The cost of isotherm depends on a few factors. There is a different isotherm price for each thickness.
Firstly, which thickness are you wanting to install. You should check with your local installer. See which thickness is right for your climatic region.
Johannesburg, Pretoria and Western Cape require the 145mm isotherm for best results. Durban and surrounding areas require the 100mm.
Why does the cost of isotherm per square meter vary according to the size of the home
Another thing to take into account. The size of your home. Additionally, the cost of isotherm per m2 can vary from home to home. Firstly, we run large qualified teams of installers. Each team has a site supervisor. This is to ensure the installation is done quickly and efficiently.
A home that is 50m2 will get a higher price per m2 than a home that is 300m2. This is because we have to cover the costs of our teams. Setting up at each installation takes a lot of time as well. Its easier to insulate 2 x 100m2 homes in a day than 4 x 50m2 homes.
Why does the price of isotherm per m2 vary according to the difficulty of the installation
Every home is different. Some homes have easy access through the trap door and sufficient space to walk around in the roof. These installation go quickly and it means you get a slightly lower isotherm price per m2.
Other roofs we have to lift tiles or remove sheeting to install from the outside. These installations are very time consuming. Therefore the price of isotherm per m2 will be higher. Suspended ceilings also take longer to install in. Which increases the isotherm cost per square meter. We have to work from below one tile at a time. It could take a full day to complete a large suspended ceiling. Furthermore, that same installation would only take a couple hours in a normal roof. All these factors influence the cost of isotherm.
