Hybrid Flat Roof

The Problem

Being a new build extension with a hybrid flat roof, it was vital that Paul achieved a 0.18 U-value to comply with building regulations. This needed to be done without having to increase the overall height of the extension, which other solutions couldn’t achieve.

The Solution

Talking to the SuperFOIL technical team, Paul was given a solution that achieved his required U-value as well as not adding any height to the extension.

Using a combination of SF40, SFTV and PIR board, Paul managed to achieve a lower U-value of 0.17. The SuperFOIL products used also provided him with a radiant barrier and vapour control layer.

SF40 is a 65mm thick product with an R-rating of 3.47 when used in a roof. As well as providing thermal insulation, it also acts as a vapour control layer and radiant barrier. SF40 provides an airtight finish to any project and is simple to install.

Paul praised the technical team stating that the “technical support was excellent and got building control off our backs”. He also added that the products were “Excellent” and “very easy to use”.
