2 in 1 Insulating Membrane

YBS Breathe-R Foil is a membrane and insulating layer for Pitched Roofs.

If you would like to insulate your roof at the same time as installing a membrane, you can replace a standard membrane with this product. This way you will insulate your roof at the same time, so you can incorporate the properties of a breather felt, with the extra benefit of thermal performance.

It’s made up of 2 layers and is only 2mm thick. The outer layer is made of a high-performing and durable roofing membrane.

The internal layer is made using highly reflective insulation grade aluminium foil (this is also fully perforated to allow moisture to escape).

Compared to a traditional breather membrane, can reduce heat loss by up to 39%. The foil insulation provides an R-Value of 0.45 which is equivalent to 20mm of Mineral Wool. Unlike other forms of loft insulation, you do not need any PPE to install Breathe-R foil. Because it doesn’t contain any harmful fibres when installed.

A roll of YBS Breathe-R Foil 2 in 1 Insulation and Membrane is 1.2m x 25m which covers a 30m2 area.
