VAPOUR CONTROL MEMBRANE
VAPOR 140
The VAPOR 140 vapour control membrane regulates the passage of moisture preventing the formation of interstitial condensation within the insulation package.
VAPOR 140, the vapour control membrane that regulates the passage of humidity.
It consists of a functional film and polypropylene protective layers and is designed for application both on the inside and outside of roofs and walls. UV resistant, it can be used directly on top of the wooden plank.
