VAPOUR CONTROL MEMBRANE WITH REINFORCING GRID
VAPOR IN NET 140
The VAPOR IN NET 140 vapour control membrane for controlling the passage of water vapour in timber structures and houses is the reinforced version of the VAPOR IN 120 membrane, the best seller in our range. It has the same functional film and the same non-woven fabric with the addition of a polypropylene reinforcing grid inside that increases its mechanical performance. It is ideal for frame systems.
VAPOR IN NET 140 vapour control membrane: perfect airtightness and great strength.
The VAPOR IN NET 140 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. VAPOR IN NET 140 is designed for indoor application.
The reinforcing grid offers great strength even in the event of pressure caused by the insulating material being blown, the installation of which gives rise to mechanical tensions that the reinforcement can compensate for, guaranteeing safe installation at all times. It is semi-transparent to simplify installation.
It is one of the products for which the EPD and LCA environmental declarations have been developed.
