Superdiffusion membrane SA130 Ondutis

Ondutis SA130 superdiffusion membrane protects the outer insulating layer in the walls and on the roof from the penetration of wind and precipitation. It has high vapor permeability: drains condensate to the outside.

It is a dark-colored polymer canvas with an insulating inner layer and fluffy outer sides that retain heat and prevent moisture from condensing and accumulating on the surface. As a result, thermal insulation and internal elements of the walls remain dry and do not freeze in winter. To preserve this effect, it is important to observe the installation rules: leave a ventilation gap between the membrane and the external finish of the roof or wall, and lay the SA130 membrane itself close to the insulation. The joints must be glued and sealed with mounting tape.

On the roof, Ondutis SA130 can be used as a temporary roof covering, but not longer than 2 months.
