135mm Aerolite R-Value

Always check the r-value and density of the product you are installing in your roof. There are many products that are 135mm thick but have much lower specifications. Give a local installer a call and check the required thickness for your area.

• 135mm – R-value 3.38 (product r-value)
• 135mm – R-value 3.8    (including roof)

Additionally, if you stay in Johannesburg, Pretoria or Western Cape then make sure you don’t install the 100mm. The 100mm is below spec for the colder regions.

Any aerolite installer that recommends you use it (except for in Durban) does not know the building laws in South Africa.

135mm Aerolite Price Per Square Meter

The 135mm aerolite fiberglass insulation price (installed) will differ from home to home. Additionally, many factors come into play. The difficulty of the installation is an important factor to consider when installing this product. High-pitched roofs will get a lower price per meter squared. This is because our installers will have sufficient space to stand in the roof and install.

Low-pitched roofs will often need to be insulated from the outside. This means that we might have to take off the roof tiles and it will be extremely time-consuming. We could insulate 2 – 3 homes in the time it takes to remove a roof and install it from the outside.
