YBS Breather Foil Fire Retardent Membrane 1.35 x 25m

Looking for a two-in-one insulating venting membrane when working with timber frame and modular building constructions? YBS BreatherFoil will outperform traditional breathable membranes and greatly increase the U-value of a timber frame wall.
Whether pre-fabricated or assembled on site, you’ll be sure of maximum flexibility when detailing timber frame walls or dormer cheeks, without the expense of thicker timber frames or higher priced materials. 
BreatherFoil’s unique design allows the application to breathe while offering improved thermal performance. Its core bubble profile offers great thermal benefits by trapping air within the small bubble pockets. The outer aluminium foil layers increase the overall thermal performance, due to their high reflectiveness.
