145mm Isotherm Price – Including Installation

We recommend getting it professionally installed. There are many things that could go wrong in the roof when attempting a DIY installation. Additionally, wiring in older houses can make installations very tricky. On average the 145mm isotherm price per m2 installed is between R89m2 and R105m2.

Additionally, the installers will have to determine the difficulty of the installation. A standard roof with a high pitch and space to stand and work will get a cheaper isotherm 145mm price per m2 as the installation will be a lot quicker. Furthermore, more difficult installations with lots of wiring and low pitched roofs will get a higher price.

Insulating a Flat Roof

You can insulate a flat tiled roof or flat corrugated roof. We can lift the metal sheeting or the tiles and install the insulation. Once complete we close up the roof. Doing it this way will increase the cost of the installation. It takes much longer and requires a bigger team. Another thing to consider is the cavity space in the flat roof section. Some flat roofs require a thinner thickness to prevent material compression. Compressing the material is good for sound but not great for thermal insulation.

What Is The 145mm Isotherm R-value?

When checking the thermal capabilities of an insulation product, the higher the R-value, the better the thermal performance of the insulation. As a matter of fact, the higher isotherm cost per roll achieves an excellent R-value. The 145mm isotherm R-value is 3.37 (product only) and an R-value of 3.7 (including roofing materials).
