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. Covered with markings on top, overlaps glued with Tyvek Tape or Gerband Outside DM Tape (386). It is recommended to insulate nail spots on roofs with low slope with Tyvek Nail Tape.
