Breathable Diffusion Membrane with Micro-perforations, 1.5x50m, 75m2

Diffusion film with micro-perforations. Used in roof constructions as a waterproof and windproof membrane with a high vapor permeability coefficient. Also used in wall constructions as a highly breathable windproof insulation. It is recommended to isolate nail spots in roofs with low slope with Gerband Nail Sealing Tape (603).
