VAPOUR CONTROL MEMBRANE
VAPOR IN 120
VAPOR IN 120 is a vapour control membrane for controlling the passage of water vapour in timber structures and houses.
It consists of a functional film and a polypropylene reinforcement and is designed for application on the inside of timber roofs and walls.
VAPOR IN 120 VAPOUR CONTROL MEMBRANE: FOR AN AIR-TIGHT ENVELOPE
The VAPOR IN 120 vapour control membrane regulates the passage of moisture into the timber structure, preventing the formation of interstitial condensation within the insulation package and increasing the durability of the structure.
It is transparent, making it easy to install when insulating from the inside or for easy installation between beams. It is also available in a 3-metre version for even faster installation times.
