Many South African homes lose valuable heating during winter and gain excessive heat during summer because their ceilings are poorly insulated. Installing quality ceiling insulation is one of the most effective ways to improve year-round indoor comfort while reducing heating and cooling costs.

Isotherm insulation has become one of South Africa’s most recognised polyester insulation products thanks to its durability, thermal performance and environmentally friendly composition. Unlike traditional fibreglass insulation, Isotherm is manufactured from recycled polyester fibres, making it soft to handle, non-irritating and safe to install.

Cape Ceilings & Drywalling provides complete Isotherm ceiling insulation installation for new homes, existing properties, offices, schools and commercial buildings throughout Cape Town and the Western Cape.

Isotherm Frequintly Asked Questions

1. What is Isotherm ceiling insulation?

Isotherm ceiling insulation is a high-performance polyester insulation manufactured from recycled PET fibres. It is designed to reduce heat transfer through your ceiling, helping to keep your home cooler during summer and warmer throughout winter. Isotherm is also non-toxic, non-irritating and environmentally friendly, making it a popular insulation choice for South African homes.


2. Is Isotherm insulation suitable for homes in Cape Town?

Yes. Isotherm performs exceptionally well in Cape Town’s climate by reducing heat gain during hot summer months while helping retain warmth during cold, wet winters. Professionally installed Isotherm insulation improves indoor comfort throughout the year while reducing energy consumption.


3. What are the benefits of installing polyester ceiling insulation?

Polyester ceiling insulation offers numerous benefits, including improved indoor comfort, lower electricity costs, reduced heat loss, better temperature control and improved acoustic performance. It is also manufactured from recycled materials, making it an environmentally responsible insulation solution.


4. Is Polyester insulation environmentally friendly?

Yes. Isotherm is manufactured from recycled polyester fibres obtained from PET plastic bottles. The product is recyclable, contains no harmful chemicals and contributes to a more sustainable building environment while delivering excellent thermal insulation.


5. Does Isotherm insulation reduce electricity costs?

Yes. Properly installed ceiling insulation reduces the amount of heat entering or leaving your home, meaning air conditioners, heaters and heat pumps operate more efficiently. This can significantly reduce monthly electricity consumption over time.


6. Is Isotherm insulation safe to install?

Yes. Unlike traditional fibreglass insulation, Isotherm does not contain glass fibres, making it soft to handle and non-irritating to the skin. Professional installation ensures the insulation is fitted correctly for maximum performance.


7. How long does Isotherm insulation last?

When professionally installed and kept dry, Isotherm insulation can provide reliable thermal performance for many years without requiring replacement. It does not easily deteriorate under normal ceiling conditions.


8. Can Isotherm insulation be installed in existing homes?

Absolutely. Most existing homes can be upgraded with Isotherm insulation without removing the ceiling. Our installation team accesses the roof space and installs the insulation neatly between the ceiling joists where possible.


9. Is Isotherm insulation suitable for new homes?

Yes. Installing Isotherm insulation during construction is highly recommended because it allows the insulation to be fitted before the ceiling is closed, ensuring complete coverage and maximum thermal performance.


10. Does Isotherm insulation help reduce noise?

Yes. In addition to its thermal performance, Isotherm also provides acoustic benefits by helping reduce noise transfer from the roof space and improving overall indoor comfort.


11. What thickness of Isotherm insulation should I install?

The correct thickness depends on your home’s design, roof construction and thermal performance requirements. Our team can assess your property and recommend the most suitable Isotherm insulation solution for maximum energy efficiency.


12. Does Isotherm insulation absorb moisture?

Isotherm polyester insulation is designed to resist moisture absorption better than many traditional insulation products. However, roof leaks should always be repaired promptly to protect both the insulation and ceiling structure.


13. Is Isotherm insulation suitable for commercial buildings?

No. Isotherm insulation should not be used in commercial buildings as it is a B/B 1/2 insulation


14. Can Isotherm insulation be installed with downlights?

Yes. Modern LED downlights can usually be accommodated during installation, provided the correct clearances and manufacturer recommendations are followed. Our installers ensure insulation is fitted safely around lighting fixtures where required.


15. Does Isotherm insulation comply with South African building requirements?

Yes. Professionally installed ceiling insulation assists buildings in meeting the thermal performance requirements contained within the South African National Standards (SANS) for energy-efficient building design.


16. How long does Isotherm insulation installation take?

Most residential ceiling insulation installations can be completed within a single day, depending on the size of the property, roof accessibility and the complexity of the installation.


17. Can ceiling insulation be installed without replacing my ceiling?

Yes. In most homes, ceiling insulation is installed through the roof space without removing the existing ceiling. This allows the upgrade to be completed quickly with minimal disruption to your home.


18. Why should I choose professional Isotherm insulation installation?

Professional installation ensures the insulation is fitted evenly without gaps or compression, allowing it to perform as intended. Correct installation also helps maximise energy efficiency, improve comfort and extend the lifespan of the insulation.
