YBS BreatherFoil FR for walls is a thin and flexible 2 in 1 insulation and venting membrane designed specifically for external walls including timber frame and modular buildings.

At only 4mm thick, this product replaces the need for a traditional breather membrane while insulating and without increasing the depth.

YBS BreatherFoil FR For Walls for Timber Frames can be installed in a factory scenario or on site by simply stapling the material directly onto timber OSB Boards allowing the reflective foil to face the external of the property.

We advise BreatherFoil to be overlapped by 75mm and the horizontal overlaps should remain untapped, to allow any moisture to dissipate. We recommend the vertical joints to be taped and sealed using Thermaseal Foil Joining Tape.

This product creates a totally draft and moisture free building during construction, and also when the project is complete!
