This torch-on underlay is a glass fibre-based roofing layer supplied in a 16m x 1m roll, suitable for use in flat roofing systems. It features a sanded upper surface and a thermofusible film on the underside for ease of installation with a roofing torch.
Commonly used as a base or intermediate layer beneath cap sheets, the underlay provides a practical solution for both new build and refurbishment projects. Its flexibility allows for secure detailing around penetrations and upstands on site.
