YBS BreatherFoil FR for Timber Frames is a 2-in-1 Breathable and Venting Membrane. It is designed and certified to replace a traditional breather membrane, aswell as greatly improving the U-value due to it’s reflective outer foil layer.

BreatherFoil FR for walls protects the timber frame’s structure during it’s construction, as it creates a wind & draught free seal.

The product can be installed in a factory scenario or on site by simply stapling the material directly on plywood timber boards allowing the reflective foil to face the external of the property. BreatherFoil FR for walls should be overlapped by 75mm and the horizontal overlaps should remain untapped, to allow any moisture to dissipate. The external of the timber frame can be installed with the external finish of your choice, such as Brick, Blockwork & Cladding.
