SFBA BB has been designed for use with both roofs and walls, ideal for timber frame and modular designs and at only 4mm thick it can offer a thermal resistance value of up to 0.833 W/m2K when adjacent to a 20mm air gap either side of the product to help maximise space and thermal efficiency.
SFBA BB's breathable design helps to reduce the risk of condensation whilst also providing a secondary rain barrier and improved air tightness. SFBA BB is a fire retardant bubble membrane with a reflective silver foil on one side.
