Professional Aerolite Ceiling Insulation Installation

Aerolite insulation remains one of the most recognised ceiling insulation products in South Africa. For decades, it has been used in homes, offices, schools, factories and commercial buildings to improve indoor comfort, reduce heat transfer and lower energy consumption.

At Cape Ceilings & Drywalling, we provide professional Aerolite insulation installation throughout Cape Town and the Western Cape. With more than 36 years of insulation experience, our team understands how to install Aerolite correctly so that it performs as intended.

Choosing the right insulation product is important, but correct installation is just as important. Gaps, compression, poor cutting and incomplete ceiling coverage can reduce the effectiveness of any insulation system. Our installation teams carefully measure, cut and fit Aerolite insulation to ensure continuous coverage across the ceiling area.

Aerolite is a glasswool insulation product designed for thermal and acoustic performance. It helps keep homes cooler during summer, warmer during winter and more comfortable throughout the year. It also provides excellent sound absorption, making it suitable for residential, commercial and light industrial applications.

Every Aerolite Insulation installation completed by Cape Ceilings & Drywalling is backed by our 5-Year Workmanship Warranty, giving customers confidence that the work has been completed professionally.

Why Choose Aerolite Insulation Installation?

Aerolite insulation is a trusted choice for homeowners and building professionals who want an effective ceiling insulation solution with proven long-term performance.

Professional Aerolite Insulation installation can help:

Reduce summer heat entering through the roof.
Retain warmth during winter.

For many South African homes, the roof is one of the biggest sources of unwanted heat gain and heat loss. Installing Aerolite above the ceiling creates a thermal barrier that slows this heat transfer, helping the building maintain more stable indoor temperatures.

What is Aerolite Insulation?

Aerolite is a flexible glasswool ceiling insulation manufactured in roll form. It is widely used in roof spaces above ceilings to improve thermal resistance and acoustic performance.

Because it is supplied in rolls, Aerolite can be fitted between roof trusses and ceiling joists, making it suitable for many South African roof structures.

Aerolite is commonly installed in:

Residential homes
Townhouses
Apartment blocks
Offices
Schools
Hospitals
Warehouses
Factories
Retail buildings
Guest houses
Hotels
Community buildings

It is available in different thicknesses, allowing property owners to choose a solution that suits their building, budget and energy-efficiency requirements.

Why Professional Aerolite Insulation Installation Matters

Choosing Aerolite insulation is an excellent investment in the comfort and energy efficiency of your property, but the quality of the installation is just as important as the product itself. Even premium insulation cannot deliver its full thermal and acoustic performance if it is installed incorrectly.

At Cape Ceilings & Drywalling, we have spent more than 36 years installing ceiling insulation in residential, commercial and industrial buildings throughout Cape Town and the Western Cape. During that time, we have seen countless examples where poor installation has significantly reduced the effectiveness of otherwise high-quality insulation.

Professional Aerolite Insulation installation ensures your Aerolite insulation performs exactly as it was designed, providing long-term comfort, lower energy consumption and reliable performance for many years.

Correct Installation Maximises Thermal Performance

Aerolite insulation works by trapping millions of tiny pockets of air within its glasswool fibres. These trapped air pockets slow the movement of heat through the ceiling, helping to maintain comfortable indoor temperatures throughout the year.

If the Ceiling insulation is compressed, poorly fitted or installed with gaps, its ability to resist heat transfer is reduced.

Our experienced Aerolite installers ensure every roll is positioned correctly so it can expand naturally and deliver maximum thermal performance throughout the ceiling area.

Why Gaps Reduce Performance

One of the most common Aerolite Insulation installation mistakes is leaving small gaps between insulation sections or around roof structures.

Although these gaps may appear insignificant, they create thermal bridges where heat can bypass the insulation.

Common areas where gaps occur include:

Around the roof trusses.
Ceiling access hatches.
Electrical wiring.
Plumbing pipes.
Roof bracing.
Air-conditioning ducting.
Roof edges.
Chimneys, where applicable.
Ceiling bulkheads.

Our installation teams carefully measure and trim every section of Aerolite insulation to minimise these gaps and maintain continuous coverage throughout the roof space.

Avoiding Insulation Compression

Glasswool insulation is designed to perform at its specified thickness.

If Aerolite insulation is compressed beneath stored items, roof timbers or other materials, the trapped air pockets are reduced, lowering its thermal efficiency.

Professional installation ensures:

Full insulation thickness is maintained.
Rolls are not unnecessarily compressed.
Insulation is evenly positioned.
Maximum R-value performance is achieved.

Maintaining the correct loft and thickness allows Aerolite insulation to continue performing effectively for decades.

Working Around Electrical Services

Modern roof spaces contain a variety of services that require careful attention during installation.

These may include:

Electrical wiring.
Junction boxes.
Solar electrical cabling.
Television cables.
Internet cabling.
Plumbing pipes.
Air-conditioning ducts.
Ventilation systems.
Ceiling-mounted extractor fans.

Our experienced installers work carefully around these services without causing unnecessary disturbance while maintaining continuous insulation coverage wherever practical.

Professional Installation Around Downlights

Downlights require special attention during ceiling insulation installation.

Every roof space is different, and the installation approach depends on the type of fittings, their heat characteristics and the manufacturer’s installation requirements.

Our Aerolite installation team carefully assesses each roof space before fitting insulation and follows good installation practices around lighting and other ceiling services to ensure a safe, professional result.

Working Around Roof Trusses

South African roof structures vary considerably depending on the age and design of the building.

We regularly install Aerolite insulation in roofs with:

Timber roof trusses.
Lightweight steel roof trusses.
Complex roof framing.
Double-volume roof structures.
Cathedral ceilings.
Renovated roof systems.

Our Aerolite installers carefully fit insulation between structural members while maintaining continuous coverage throughout the accessible roof space.

Replacing Older or Damaged Insulation

Many homes already contain insulation that was installed years ago.

During our roof inspection, we frequently discover insulation that has:

Been damaged by roof leaks.
Become flattened over time.
Been disturbed by electricians.
Been moved during plumbing work.
Been compressed by stored items.
Been incorrectly installed originally.
Been damaged by rodents or birds.

Where appropriate, we recommend replacing deteriorated insulation with new Aerolite insulation to restore the building’s thermal performance.

Safe Access Inside Roof Spaces

Working inside roof cavities requires both experience and careful planning.

Our installation teams are trained to move safely through roof spaces while protecting the ceiling below.

During every installation, we take care to:

Use safe access points.
Protect ceiling finishes.
Avoid unnecessary pressure on ceiling boards.
Work carefully around structural members.
Minimise disruption inside the home.
Leave the roof space neat upon completion.

This careful approach helps protect both the property and the newly installed insulation.

Quality Control After Every Installation

Our work does not end when the last roll of insulation has been installed.

Before completing the project, we carry out a final inspection to ensure:

Complete insulation coverage has been achieved.
Significant gaps have been eliminated.
Insulation has not been unnecessarily compressed.
Electrical services remain accessible.
The roof space has been left clean and safe.
The installation meets our workmanship standards.

This final quality check gives both our team and our customers confidence that the installation has been completed correctly.

Common Problems We Find During Roof Inspections Before Installing Aerolite Insulation

One of the biggest advantages of having your Aerolite insulation professionally installed is that every project begins with a thorough inspection of your roof space. After more than 36 years of installing ceiling insulation, we have inspected thousands of roofs throughout Cape Town and the Western Cape.

Very few roof spaces are perfect.

Many buildings contain insulation that has been installed incorrectly, damaged over time, or never properly completed during the original construction. Identifying these issues before installation allows us to recommend the best solution and helps ensure your new Aerolite insulation performs to its full potential.

Below are some of the most common problems we encounter during roof inspections.

Missing Insulation Over Garages

One of the most common issues we find is garages that have never been insulated.

Builders often focus on insulating the main living areas while leaving the garage ceiling completely exposed.

Although this may seem unimportant, heat entering through the garage ceiling can still affect rooms located above or adjacent to the garage.

Where practical, we recommend insulating these areas to improve the overall thermal performance of the home.

Incomplete Ceiling Coverage

It is surprisingly common to find homes where only part of the ceiling has been insulated.

Examples include:

Bedrooms are insulated, but passageways are left uncovered.
Living rooms insulated while kitchens remain exposed.
Extensions were never insulated after renovations.
New additions were built without matching the original insulation.

Even relatively small uncovered areas allow heat to bypass the insulation system, reducing its overall effectiveness.

Gaps Around Roof Access Hatches

Access hatches are frequently overlooked during insulation installations.

Without insulation around or above the access hatch, valuable heat can escape during winter while unwanted heat enters during summer.

Our installers carefully assess these areas and recommend practical solutions where appropriate to maintain continuous thermal protection.

Compressed Insulation

We regularly find insulation that has been flattened by:

Storage boxes.
Building materials.
Timber offcuts.
Water tanks.
Air-conditioning equipment.
People repeatedly walk through the roof space.

Compressed insulation loses much of its insulating ability because the trapped air pockets within the glasswool are reduced.

Where possible, we reposition or replace damaged insulation to restore its performance.

Roof Leaks Damaging Existing Insulation

Water damage is another common problem.

Older roof leaks often leave insulation:

Flattened.
Contaminated.
Torn.
Permanently damaged.

Before installing new Aerolite insulation, we recommend repairing any active roof leaks to protect the new insulation and maximise its service life.

Rodent Activity

Although Aerolite insulation itself is not a food source, rodents sometimes enter roof spaces through damaged roof coverings or unsealed openings.

During inspections, we occasionally find evidence of:

Rodent nests.
Droppings.
Disturbed insulation.
Damaged ceiling areas.

Where significant rodent activity is present, we recommend addressing the infestation before installing new insulation.

Bird Nesting in Roof Spaces

Small birds sometimes enter roof cavities through damaged roof tiles, loose flashing or ventilation openings.

This can result in:

Nesting material.
Disturbed insulation.
Debris.
Reduced insulation coverage.

Any entry points should be repaired before completing the insulation installation.

Insulation Disturbed by Electricians

Electrical contractors often need access to roof spaces when installing:

Additional lighting.
Solar power systems.
Alarm wiring.
Internet cabling.
Security cameras.

Unfortunately, insulation is not always repositioned correctly afterwards.

This leaves uncovered ceiling sections that reduce thermal performance.

Our inspections frequently identify these areas so they can be corrected during installation.

Solar Installation Disturbance

With the rapid growth of residential solar systems, we increasingly find roof spaces where insulation has been moved to allow electricians access to wiring.

While installing solar panels is an excellent investment, displaced insulation should always be returned to its original position once the electrical work has been completed.

Where necessary, we restore continuous insulation coverage as part of our installation process.

Poor DIY Installations

Many homeowners attempt to install ceiling insulation themselves.

While well-intentioned, DIY installations often contain problems such as:

Uneven insulation coverage.
Incorrect cutting.
Large gaps.
Excessive compression.
Missing sections.
Poor fitting around the roof trusses.
Inconsistent insulation thickness.

Professional installation ensures the insulation performs far more effectively over the long term.

Builders Cutting Corners

On some new housing developments, insulation has been installed simply to satisfy minimum building requirements rather than to maximise performance.

We occasionally find:

Large uncovered ceiling sections.
Incorrect insulation thickness.
Poor workmanship.
Incomplete installations.
Gaps around structural members.
Loose insulation rolls.

Correcting these issues significantly improves the thermal efficiency of the building.

Mixed Insulation Products

Another situation we encounter is roofs containing several different insulation products installed at different times.

For example:

Old fibreglass insulation alongside newer products.
Partial Aerolite installations.
Polyester insulation mixed with glasswool.
Sections added during renovations.

Although mixed insulation can sometimes function adequately, inconsistent installation often results in uneven thermal performance.

We assess each roof individually and recommend the most practical long-term solution.

Poor Roof Access Planning

Some roof spaces contain extremely limited access, making installation more challenging.

Our experienced team carefully plans each project to ensure even difficult-to-reach sections receive insulation wherever practical.

Years of experience working in complex roof spaces allow us to achieve excellent coverage while maintaining safe working practices.

We Believe Every Aerolite Insulation Installation Starts with a Proper Inspection

The quality of any insulation installation depends on understanding the roof space before work begins.

That is why every Aerolite insulation project starts with a careful assessment of the roof structure, existing insulation, electrical services, ventilation and overall roof condition.

By identifying potential problems before installation, we can provide practical recommendations and ensure your new Aerolite insulation delivers the maximum thermal and acoustic performance for many years to come.

New Homes vs Existing Homes – Aerolite Insulation Installation

One of the biggest advantages of Aerolite Ceiling insulation is its versatility. Whether you are constructing a brand-new home, renovating an older property or upgrading an existing building that has never had ceiling insulation, Aerolite can be professionally installed to significantly improve thermal comfort and energy efficiency.

Although the Aerolite insulation product remains the same, the Aerolite installation process differs depending on the stage of construction. At Cape Ceilings & Drywalling, we have more than 36 years of experience installing Aerolite insulation in both new developments and existing buildings throughout Cape Town and the Western Cape.

Every project begins with a detailed inspection of the roof structure, allowing us to determine the safest and most effective installation method while ensuring the insulation delivers maximum long-term performance.

Installing Aerolite During New Construction

The ideal time to install Aerolite insulation is during the construction phase, before the ceiling boards have been fitted.

With the ceiling still open, our installers have unrestricted access to the entire roof structure, allowing the insulation to be positioned accurately and efficiently across the full ceiling area.

Installing insulation at this stage also allows builders, electricians and other contractors to complete their work without disturbing finished ceilings later.

During a new-build installation, we:

Inspect the roof structure.
Confirm roof truss spacing.
Measure the total ceiling area.
Calculate the required insulation quantities.
Position Aerolite neatly between roof trusses.
Fit insulation around structural members.
Ensure continuous coverage across the ceiling.
Complete a quality inspection before ceiling boards are installed.

This method produces excellent results because every part of the ceiling is easily accessible.

Benefits of Installing During Construction

Installing Aerolite before the ceilings are closed offers several advantages.

These include:

Faster installation.
Complete roof access.
More accurate fitting.
Continuous insulation coverage.
Reduced labour time.
Easier quality inspections.
Less disruption to other building trades.
Maximum long-term thermal performance.

For new homes, this is generally the most efficient and cost-effective installation method.

Installing Aerolite in Existing Homes

Many South African homes were built before ceiling insulation became standard practice.

Fortunately, Aerolite insulation can usually be installed in existing homes without removing the ceiling.

Our installation teams access the roof space through the ceiling access hatch and carefully work above the existing ceiling structure.

Although retrofit installations require more planning and care, they can still provide excellent thermal and acoustic performance when completed professionally.

Inspecting the Existing Roof Space

Before beginning any retrofit installation, we conduct a detailed inspection of the roof cavity.

This allows us to assess:

Roof access.
Existing insulation.
Roof truss layout.
Electrical wiring.
Plumbing services.
Air-conditioning ducting.
Roof ventilation.
Downlights.
Signs of roof leaks.
General roof condition.

Identifying these factors before installation allows us to recommend the most suitable Aerolite solution while avoiding unexpected issues during the project.

Working Around Existing Building Services

Modern roof spaces contain numerous building services that require careful planning.

Our experienced installers regularly work around:

Electrical wiring.
Solar electrical systems.
Plumbing pipes.
Air-conditioning ducts.
Ventilation systems.
Alarm cables.
Fibre internet cabling.
Ceiling-mounted extractor fans.
Structural bracing.

Each section of Aerolite insulation is carefully fitted around these services while maintaining continuous thermal coverage wherever practical.

Protecting Existing Ceilings

Homeowners often worry that ceiling insulation installation could damage their ceilings.

Our experienced team takes great care while working inside roof spaces.

We:

Use established access routes.
Work from the roof structure wherever possible.
Protect existing ceiling finishes.
Avoid placing unnecessary pressure on ceiling boards.
Keep disruption inside the home to a minimum.
Leave the roof space clean upon completion.

Our careful working methods help ensure your home remains in excellent condition throughout the installation process.

Replacing Old Aerolite or Existing Insulation

Not every roof space is empty when we arrive.

Many homes already contain older insulation that may no longer provide effective thermal performance.

During our inspection, we assess whether the existing insulation remains suitable or whether replacement would provide better long-term results.

Common problems include:

Water-damaged insulation.
Compressed insulation.
Incomplete ceiling coverage.
Rodent damage.
Bird contamination.
Insulation disturbed by electricians.
Poor original installation.
Missing sections following renovations.

Where replacement is recommended, we remove the deteriorated insulation where appropriate and install new Aerolite insulation to modern standards.

Renovation and Extension Projects

Renovations provide an excellent opportunity to improve the energy efficiency of a building.

We regularly install Aerolite insulation during:

Home extensions.
Roof replacements.
Ceiling replacements.
Loft conversions.
Commercial renovations.
Office refurbishments.
Retail fit-outs.
Building upgrades.

Adding insulation during these projects is often more economical than returning after construction has been completed.

Every Roof Space is Different

No two roof spaces are exactly alike.

Factors such as roof pitch, truss spacing, ceiling height, access limitations and building services all influence the installation process.

That is why every Aerolite installation begins with a detailed assessment rather than relying on standard assumptions.

Our experience allows us to adapt the installation method to suit each individual building while maintaining high workmanship standards throughout the project.

Professional Installation Delivers Long-Term Results

Careful planning.
Accurate measurements.
Selecting the correct insulation thickness.
Safe working practices.
Attention to detail.
Thorough quality inspections.
Long-term customer satisfaction.

By following a structured installation process on every project, we ensure that your Aerolite insulation performs exactly as it was designed to, helping create a more comfortable, energy-efficient and valuable property.

How Aerolite Insulation Improves Energy Efficiency

One of the main reasons homeowners and businesses invest in Aerolite insulation is to improve the energy efficiency of their buildings. With electricity prices continuing to rise across South Africa, reducing unnecessary heating and cooling costs has become more important than ever.

A professional Aerolite Insulation installation system helps reduce heat transfer through the ceiling, allowing buildings to maintain more stable indoor temperatures throughout the year. Instead of constantly relying on heaters during winter or air conditioners during summer, insulation allows the building itself to work more efficiently.

At Cape Ceilings & Drywalling, we have installed Aerolite insulation in thousands of homes and commercial buildings over more than 36 years, and one of the first comments customers often make is how much more comfortable their property feels after the installation has been completed.

Understanding How Heat Moves Through Your Roof

Many homeowners are surprised to learn that the roof is one of the largest sources of heat transfer in a building.

During summer, the sun heats the roof covering throughout the day. That heat builds up inside the roof cavity before eventually passing through the ceiling into the rooms below.

During winter, the opposite happens.

Warm air produced by heaters, fireplaces and normal household activities naturally rises towards the ceiling. Without insulation, much of this warmth escapes into the roof space before being lost through the roof.

Aerolite insulation slows this movement of heat in both directions, helping to maintain a far more consistent indoor temperature throughout the year.

Cooler Homes During Summer

Cape Town’s summers can place tremendous heat stress on buildings, particularly those with large roof areas exposed to direct sunlight.

Without ceiling insulation, roof spaces can become extremely hot, causing indoor temperatures to rise throughout the afternoon.

Professionally installed Aerolite insulation helps by:

Reducing heat entering through the ceiling.
Slowing radiant heat transfer.
Keeping living areas more comfortable.
Reducing hot spots inside the home.
Improving comfort during heatwaves.
Creating a cooler indoor environment.

This allows families to enjoy greater comfort even during the hottest months of the year.

Warmer Homes During Winter

Winter mornings in the Western Cape can become surprisingly cold, particularly in homes without ceiling insulation.

Aerolite insulation helps retain valuable indoor warmth by reducing heat escaping through the ceiling.

Benefits include:

Warmer bedrooms.
More comfortable living areas.
Improved overnight temperatures.
Reduced heat loss.
Better winter comfort.

Instead of heating constantly replacing lost warmth, the building retains heat for longer, making indoor spaces feel more comfortable throughout the day and night.

Lower Electricity Bills

One of the greatest long-term benefits of Aerolite insulation is its ability to reduce energy consumption.

When less heat enters the building during summer and less warmth escapes during winter, heating and cooling systems do not need to work as hard.

Potential benefits include:

Reduced air-conditioner operating time.
Lower heating costs.
Reduced electricity consumption.
Improved energy efficiency.
Lower monthly utility expenses.

Although every building performs differently depending on its size, design and occupancy, ceiling insulation is widely recognised as one of the most cost-effective improvements for reducing long-term energy costs.

Less Dependence on Heating and Cooling Systems

Heating and cooling equipment work hardest when indoor temperatures fluctuate dramatically.

Aerolite insulation helps maintain a more stable indoor environment, reducing the workload placed on these systems.

This may help:

Extend the lifespan of air conditioners.
Reduce wear on heating equipment.
Lower maintenance costs.
Improve HVAC efficiency.
Reduce operating expenses.

By reducing unnecessary strain on climate-control systems, Aerolite insulation supports more efficient building operation throughout the year.

Improved Indoor Comfort

While lower electricity bills are an important benefit, many customers value the improved comfort even more.

A professionally insulated home feels noticeably different.

Occupants often experience:

More consistent room temperatures.
Fewer uncomfortable hot spots.
Less temperature fluctuation between rooms.
Better sleeping conditions.
Improved comfort during extreme weather.
A more enjoyable living environment.

These comfort improvements are experienced every day, making Aerolite insulation one of the most rewarding long-term investments for any property.

Long-Term Return on Investment

Unlike many home improvements that require ongoing maintenance or regular replacement, Aerolite insulation continues working quietly above your ceiling for decades.

Once professionally installed, it requires very little attention while continuing to provide:

Lower energy consumption.
Improved comfort.
Better building efficiency.
Increased property appeal.
Long-term financial savings.

For many homeowners, the energy savings achieved over the life of the insulation can substantially outweigh the original installation cost.

Supporting Sustainable Building Practices

Reducing electricity consumption benefits both property owners and the environment.

By reducing the amount of energy required to heat and cool a building, Aerolite insulation helps lower overall energy demand.

Aerolite is also manufactured using recycled glass, making it a responsible choice for environmentally conscious homeowners, builders and developers.

When combined with good building design and professional installation, Aerolite insulation contributes to more sustainable, energy-efficient buildings throughout South Africa.

Why Professional Installation Maximises Energy Savings

Even the highest-quality insulation cannot perform properly if it is installed incorrectly.

Common installation mistakes such as:

Leaving gaps.
Compressing the insulation.
Missing ceiling sections.
Poor fitting around roof trusses.
Incomplete coverage.

All reduce the insulation’s ability to slow heat transfer.

At Cape Ceilings & Drywalling, every Aerolite insulation installation is completed with careful attention to detail to ensure the insulation performs exactly as intended.

Our experienced installers:

Measure accurately.
Fit insulation neatly between roof trusses.
Avoid unnecessary compression.
Eliminate significant thermal gaps.
Carefully work around electrical services.
Inspect every completed installation.

This professional approach helps ensure your Aerolite insulation continues delivering reliable comfort, lower energy costs and excellent thermal performance for many years.

A Smarter Investment for Every Property

Whether you own a family home, commercial office, warehouse or industrial facility, Aerolite insulation is one of the most effective investments you can make to improve building performance.

By reducing heat transfer, improving indoor comfort and lowering energy consumption, professionally installed Aerolite insulation delivers benefits that continue long after the installation has been completed.

Combined with more than 36 years of professional installation experience, Cape Ceilings & Drywalling provides Aerolite insulation solutions that help create buildings that are more comfortable, more efficient and more economical to operate throughout every season.

Fire Safety, Moisture Resistance and Long-Term Durability

When choosing ceiling insulation, thermal performance is only one part of the decision. Homeowners, builders, architects and commercial property owners also want to know that the insulation they select is safe, durable and capable of performing reliably for many years.

Aerolite insulation has earned an excellent reputation throughout South Africa not only for its thermal and acoustic performance but also for its fire safety characteristics and long service life. Manufactured from premium glasswool, Aerolite provides dependable performance while helping create safer, more energy-efficient buildings.

At Cape Ceilings & Drywalling, every Aerolite insulation installation begins with a thorough inspection of the roof space to ensure the insulation is installed safely and performs to its full potential throughout its service life.

Aerolite’s Fire Performance

Fire safety is an important consideration in every building.

Aerolite insulation is manufactured from non-combustible glasswool fibres and carries a Class A/A 1/1 fire rating, making it one of the most trusted insulation products available for residential, commercial and industrial applications.

Although insulation cannot prevent a fire from starting, selecting a non-combustible insulation product means it does not act as a fuel source if a fire occurs within the building.

For this reason, Aerolite insulation is widely installed in:

Residential homes.
Apartment buildings.
Schools.
Universities.
Hospitals.
Commercial offices.
Shopping centres.
Hotels.
Warehouses.
Industrial facilities.

Its excellent fire performance is one of the reasons Aerolite continues to be specified by architects, builders and consulting engineers throughout South Africa.

Why Fire Safety Matters in Roof Spaces

Modern roof spaces contain a variety of services, including electrical wiring, lighting circuits, ventilation equipment and plumbing systems.

Before installing Aerolite insulation, our experienced team carefully inspects the roof cavity for any visible issues that may require attention.

Where appropriate, we recommend that damaged electrical wiring or other safety concerns are repaired by a qualified electrician before the insulation is installed.

This proactive approach helps ensure both the safety of the roof space and the long-term performance of the insulation.

Professional Installation Supports Fire Safety

Correct installation contributes to maintaining a safe and well-organised roof space.

Our installers:

Work carefully around electrical wiring.
Avoid damaging existing services.
Maintain access to equipment where required.
Follow good installation practices around ceiling fittings.
Leave the roof space neat and organised after installation.

By combining premium Aerolite insulation with experienced workmanship, we help ensure every installation is completed safely and professionally.

Moisture Resistance

The Western Cape experiences wet winters, coastal humidity and changing seasonal conditions that can affect roof spaces.

Aerolite insulation is designed to perform reliably in normal roof environments when installed in a dry, weatherproof roof cavity.

The glasswool fibres themselves do not rot and are not affected by normal atmospheric humidity.

However, like any insulation product, Aerolite performs best when protected from ongoing roof leaks and standing water.

Maintaining a sound roof covering is one of the most important factors in preserving the long-term performance of your insulation.

Resistance to Mould and Mildew

A common concern among homeowners is whether insulation encourages mould growth.

Aerolite glasswool does not provide a food source for mould, mildew or fungi.

When installed inside a dry, well-maintained roof space with adequate ventilation, Aerolite insulation contributes to a healthy indoor environment while continuing to provide reliable thermal performance.

If roof leaks occur, repairing the source of moisture promptly helps protect both the insulation and the roof structure.

Condensation Control

Condensation develops when warm, moisture-laden air comes into contact with cooler building surfaces.

Although ceiling insulation is not a replacement for proper roof ventilation, Aerolite insulation helps reduce temperature differences across the ceiling, which may contribute to reducing condensation under normal building conditions.

For buildings with specialised moisture-control requirements, we can also advise on suitable roof ventilation solutions to complement the insulation system.

Excellent Performance in Coastal Areas

Cape Town and the West Coast expose buildings to coastal humidity, salt-laden air and changing weather conditions throughout the year.

Aerolite insulation has been successfully installed in coastal properties for many years and continues to provide reliable performance when protected by a properly maintained roof.

We regularly install Aerolite insulation in coastal areas, including:

Blouberg.
Melkbosstrand.
Big Bay.
Table View.
Langebaan.
Saldanha.
Vredenburg.
Jacobsbaai.
St Helena Bay.
Paternoster.
Yzerfontein.

These properties benefit from improved indoor comfort throughout every season while reducing the impact of external temperature fluctuations.

Long-Term Durability

One of Aerolite’s greatest strengths is its longevity.

Once professionally installed and protected from water damage or unnecessary disturbance, Aerolite insulation is designed to provide reliable thermal and acoustic performance for many decades.

Unlike many building improvements that require ongoing servicing or replacement, ceiling insulation generally performs quietly in the background with very little maintenance.

This makes it one of the most cost-effective long-term investments for homeowners and commercial property owners alike.

Looking After Your Aerolite Insulation

Although Aerolite insulation requires very little maintenance, periodic roof inspections are recommended.

We suggest checking the roof space after severe storms or roof repairs for:

Roof leaks.
Damaged roof coverings.
Water staining.
Disturbed insulation.
Rodent activity.
Electrical work that may have displaced insulation.
Stored items compressing the insulation.

Correcting these issues promptly helps ensure the insulation continues performing efficiently throughout its service life.

Built to Perform for Decades

Aerolite insulation has earned its reputation through decades of reliable performance in South African homes and commercial buildings.

Its combination of excellent thermal efficiency, sound absorption, Class A/A 1/1 fire performance, moisture resistance and long service life makes it one of the most dependable ceiling insulation products available.

When professionally installed by Cape Ceilings & Drywalling, Aerolite insulation provides a long-term solution that improves comfort, reduces energy costs and contributes to safer, more efficient buildings for many years to come.

Frequently Asked Questions About Aerolite Insulation Installation

How much does Aerolite insulation installation cost?

The cost of Aerolite insulation installation depends on several factors, including the size of your ceiling area, the insulation thickness you choose, the accessibility of the roof space and whether the property is a new build or an existing home. Larger homes, double-storey properties and commercial buildings may require additional labour due to more complex roof structures. At Cape Ceilings & Drywalling, we prepare detailed quotations based on accurate site measurements rather than estimates, ensuring you receive competitive installed pricing with no hidden surprises. Contact us for a free, obligation-free quotation tailored to your project.

Which Aerolite insulation thickness should I choose?

The right Aerolite insulation thickness depends on your building, your budget and your long-term energy-saving goals. 135mm Aerolite provides the highest level of thermal performance and is ideal for homeowners looking for maximum comfort and lower energy consumption. 100mm Aerolite is an excellent all-round option for most homes, offering an outstanding balance between performance and affordability. 50mm Aerolite is commonly used where roof space is limited or for applications requiring moderate insulation levels. During our roof inspection, we recommend the most suitable option based on your specific property and requirements.

Is the 135mm Aerolite worth the additional investment?

For many homeowners, yes. The thicker insulation provides greater resistance to heat transfer, helping to keep homes cooler during Cape Town’s hot summers and warmer throughout winter. Over many years, the reduction in heating and cooling costs can help offset the higher initial investment. If you intend to remain in your property for the long term, 135mm Aerolite is often one of the most cost-effective improvements you can make.

Can Aerolite insulation be installed in an existing home?

Yes. In fact, many of our Aerolite installations take place in existing homes that were built before ceiling insulation became common. We usually install the insulation from inside the roof space through the ceiling access hatch without removing the existing ceilings. Before beginning work, we inspect the roof cavity, electrical wiring and any existing insulation to ensure the installation can be completed safely and professionally.

Can Aerolite insulation be installed over existing insulation?

In some cases, yes. If the existing insulation remains in good condition and has been installed correctly, additional insulation may be possible. However, if the insulation has been damaged by roof leaks, compressed over time, disturbed during electrical work or no longer performs effectively, replacement may provide better long-term results. We assess every roof individually before making a recommendation.

How long does Aerolite insulation installation take?

Installation time depends on the size of the property, the complexity of the roof structure and accessibility within the roof space. Most average-sized residential homes can often be completed within a single day, while larger commercial or industrial projects may require additional time. Before installation begins, we provide an estimated project duration so you know what to expect.

Will Aerolite insulation reduce my electricity bill?

Professionally installed Aerolite insulation helps reduce heat entering your home during summer and slows heat loss during winter. This allows air conditioners and heaters to operate more efficiently and often for shorter periods, reducing overall electricity consumption. While the exact savings vary depending on the building and how it is used, ceiling insulation is widely recognised as one of the most effective long-term energy-saving improvements available.

Does Aerolite insulation reduce outside noise?

Yes. In addition to improving thermal performance, Aerolite glasswool insulation also provides excellent sound absorption. Many homeowners notice reduced traffic noise, less outside disturbance and quieter indoor living spaces after installation. It can also improve acoustic comfort within commercial buildings, schools and offices by reducing sound transmission through ceiling spaces.

Is Aerolite insulation safe for homes with children and pets?

Once professionally installed above the ceiling, Aerolite insulation is a safe and reliable building product. It remains inside the roof space and does not interfere with the normal use of your home. Manufactured from high-quality glasswool with a Class A/A 1/1 fire rating, Aerolite is widely used in residential, commercial and public buildings throughout South Africa and is designed to provide many years of dependable performance.

How long does Aerolite insulation last?

Aerolite insulation is designed to provide reliable thermal and acoustic performance for decades. When protected from roof leaks, physical damage and unnecessary disturbance, it continues working with very little maintenance. Regular roof inspections and prompt repair of any leaks will help ensure the insulation remains in excellent condition throughout its service life, making it a valuable long-term investment.

Can Aerolite insulation get wet?

Aerolite insulation is designed to perform in dry roof spaces protected by a sound roof covering. If a roof leak develops, it should be repaired as soon as possible to prevent ongoing moisture exposure. During our inspections, we check for signs of roof leaks, water damage and damp insulation before beginning any installation. Once the roof has been repaired and the roof space is dry, the insulation can continue providing reliable thermal and acoustic performance. Regular roof maintenance is the best way to protect both your insulation and your home.

Does Aerolite insulation help reduce condensation?

Aerolite insulation helps maintain more consistent indoor temperatures, which can reduce the conditions that contribute to condensation. However, condensation is influenced by several factors, including humidity levels, ventilation and building design. Insulation should always work together with good roof ventilation rather than replacing it. If condensation has been an issue in your property, we can assess the roof space and recommend the most suitable insulation and ventilation solution.

Is Aerolite insulation fire-resistant?

Yes. Aerolite insulation is manufactured from non-combustible glasswool fibres and carries a Class A/A 1/1 fire rating, making it a trusted choice for residential, commercial and industrial buildings. While no insulation product can prevent a fire from starting, Aerolite does not act as a fuel source and contributes to safer building design. Before every installation, we inspect the roof space and recommend that any damaged electrical wiring or other visible safety concerns be addressed before the insulation is installed.

Can I install Aerolite insulation myself?

Although Aerolite insulation is available to homeowners, professional installation offers significant advantages. Working inside roof spaces can be physically demanding and often involves electrical wiring, plumbing pipes, air-conditioning ducting and restricted access. Correctly fitting insulation around these obstacles without leaving gaps requires experience. Professional installation helps ensure the insulation performs to its designed thermal rating while reducing the risk of accidental damage to ceilings or roof structures.

Do you remove old insulation before installing Aerolite?

Where necessary, yes. During our roof inspection, we assess the condition of any existing insulation. If it has been damaged by water, compressed over time, contaminated by rodents or incorrectly installed, we may recommend removing and replacing it. If the existing insulation remains in good condition and continues to perform effectively, we will advise whether it can remain in place. Every recommendation is based on the condition of your specific roof space.

Can Aerolite insulation be installed during winter?

Yes. Winter is actually an excellent time to install ceiling insulation because homeowners often experience the benefits immediately. Once installed, Aerolite insulation helps retain indoor warmth, making living areas more comfortable while reducing reliance on heaters. We install insulation throughout the year, although severe weather may occasionally affect scheduling. We will always keep you informed if weather conditions are likely to influence your installation date.

Will Aerolite insulation increase the value of my property?

Professionally installed ceiling insulation is viewed by many buyers as a valuable feature because it improves comfort and reduces long-term operating costs. While insulation is only one of many factors that influence property value, an energy-efficient home with lower heating and cooling requirements is often more attractive to prospective purchasers or tenants. It is an investment that continues adding value long after installation.

Do you install Aerolite insulation in commercial and industrial buildings?

Yes. Cape Ceilings & Drywalling has extensive experience installing Aerolite insulation in commercial offices, schools, hospitals, warehouses, factories, shopping centres, hotels, agricultural buildings and many other types of commercial properties. Whether the project involves a small office or a large industrial facility, we apply the same professional planning, installation methods and quality workmanship to every project.

Do you provide free quotations for Aerolite insulation installation?

Yes. We provide detailed, obligation-free quotations based on the specific requirements of your project. Wherever possible, we inspect the roof space, measure the ceiling area and recommend the most suitable Aerolite insulation thickness before preparing your quotation. This ensures accurate material calculations, transparent pricing and a solution tailored to your property and budget.

Why should I choose Cape Ceilings & Drywalling for my Aerolite insulation installation?

With more than 36 years of insulation installation experience, Cape Ceilings & Drywalling has built a reputation for professional workmanship, honest advice and dependable service. We specialise in residential, commercial and industrial insulation projects and install genuine Aerolite insulation products using experienced installation teams. Our customers benefit from accurate quotations, careful roof inspections, quality workmanship, competitive installed pricing and the peace of mind provided by our 5-Year Workmanship Warranty. Our goal is to deliver insulation solutions that improve comfort, reduce energy costs and provide lasting value.

How soon can you install my Aerolite insulation?

Installation times depend on our current schedule, the size of your project and whether the insulation is being installed in a new building or an existing property. Smaller residential homes can often be scheduled relatively quickly, while larger commercial and industrial projects may require additional planning. Once your quotation has been accepted, we will confirm a convenient installation date and ensure all materials are available before work begins. Our goal is to complete every project efficiently without compromising on workmanship.

What preparation is required before installation?

Very little preparation is required from the homeowner. We recommend ensuring that the ceiling access hatch is easily accessible and that any valuable items beneath the access point are moved before our team arrives. If the roof space is being used for storage, removing stored items beforehand allows us to work more safely and efficiently. After inspecting your property, we will advise you if any additional preparation is required before installation begins.

Will the installation create a mess?

Our installation teams take pride in maintaining clean and organised work areas throughout every project. Most of the work takes place inside the roof cavity, meaning disruption inside your home or business is generally minimal. Once the installation has been completed, we remove insulation offcuts, packaging materials and any waste generated during the project. Before leaving, we carry out a final inspection to ensure the work area has been left neat, clean and ready for normal use.

Can you install Aerolite insulation in double-storey homes?

Yes. We regularly install Aerolite insulation in double-storey homes, luxury residences, townhouses and architecturally designed properties throughout Cape Town and the Western Cape. These homes often have more complex roof structures, but our experienced installers carefully assess each roof layout before beginning work. By planning the installation correctly, we achieve excellent insulation coverage while maintaining high workmanship standards throughout the project.

Do I need to leave my home during the installation?

In most cases, no. Because the installation is completed from within the roof space, homeowners can usually remain in the property while the work is being carried out. You may hear installers moving above the ceiling, but disruption inside the home is generally limited. If a particular project requires special arrangements due to access or safety considerations, we will discuss these with you before the installation begins.

Does Aerolite insulation attract rodents or insects?

Aerolite insulation is manufactured from glasswool and does not provide a food source for rodents or insects. However, if rodents already have access to the roof space, they may still enter through damaged roof coverings or other openings. We recommend maintaining the roof structure, sealing entry points and carrying out routine inspections to minimise the risk of pests entering the roof cavity. Keeping the roof in good condition also helps protect the insulation over the long term.

Can electricians or solar installers damage the insulation after it has been installed?

Future maintenance work inside the roof space may require electricians, plumbers or solar installers to move sections of insulation to gain access to services. If the insulation is not repositioned correctly afterwards, gaps may be created that reduce its thermal performance. Whenever work is carried out in the roof space, we recommend ensuring the insulation is returned to its original position. If extensive work has been completed, we are happy to inspect the insulation and advise whether any adjustments are necessary.

Does Aerolite insulation require maintenance?

Aerolite insulation requires very little maintenance once it has been professionally installed. We recommend occasional roof inspections to check for roof leaks, disturbed insulation, rodent activity or any damage caused during maintenance work. As long as the roof remains weatherproof and the insulation is left undisturbed, it should continue providing reliable thermal and acoustic performance for many decades.
