Good Roof Insulation is key to keeping your home warm in winter and cool in summer. It’s one of the most important investments you can make in your home, and it’s not as expensive as you might think. Cheap Roof Insulation can do more harm than good. We have a wide range of Thermal Insulation Products to choose from, so you can find the perfect one for your home. Our products are made from high-quality materials that will keep your home comfortable all year round.


As a homeowner, you know that Roof Insulation is important for keeping your home comfortable. But did you know Thermal Insulation is compulsory in all new homes? Insulating your home is one of the best ways to save energy and money, so make sure your home is up to code! For this reason, it is important not only from a financial perspective but also because energy costs significantly impact global warming and climate change. This change aims to build more energy-efficient homes, resulting in less need for heating and cooling. Roof insulation is particularly important, as it blocks 90% of heat flow via the ceiling into the home. A further 30% is lost via the windows, so if you have double-glazed windows, you won’t lose any heat through them.


There are many types of thermal insulation on the market, from home insulation products to high-temperature industrial insulation used in furnaces and boilers. However, we are only focusing on insulation for homes and Soundproofing and acoustics.


Isoboard Thermal Ceilings are by far the most popular ceiling option on the market today.

2.5 Star Isotherm ceiling Insulation

Isotherm insulation was once a trusted product with a 4-star rating. However, it is no longer approved by the SABS, and its rating has been reduced to 2.5 stars. The main reason for this is because Isotherm is now considered a combustible material. For this reason, it cannot be installed in hospitals or schools, as the fire risk is too high. However, Isotherm can still be used in other applications where the fire risk is not as significant. Sadly Isotherm is no longer popular.
