Looking for the isotherm price list for DIY installations? Below are the Isotherm prices available in South Africa. It’s important to note:
- tiled roofs use the 750mm wide double packs
- corrugated or metal roofs use the 1.2 wide single packs
It might seem like the 1.2m wide rolls are cheaper than the 750mm wide at first glance, but in fact, you get more area per roll in the latter. They work out to around the same price in the end.
