Ondutis SA115 superdiffusion membrane

Ondutis SA115 superdiffusion membrane is a non-woven polymeric material with a piled surface on both sides. Thanks to this composition, the membrane film has high vapor permeability, prevents the formation of water droplets from condensate, and retains heat well. Keeps the insulation and internal structures of the house dry, prevents the weathering of the heat-insulating layer.

Therefore, Ondutys SA115 is advisable to use when insulating building facades and roofs. It can also be used as a temporary roof covering, but only for 1 month.

The membrane is mounted with the logo facing up, and the unpainted side close to the insulation. When installing an insulated roof, there should be a ventilation gap of at least 3 cm between the external finish and the SA115. For gluing the joints and abutments, you need to buy mounting tape.
