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.
Description
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.

Description
The application surface must be dry, free of dust and grease. Surface elements must be removed so that the membrane is not damaged during application.
The membrane is made of a reinforcement mesh that provides excellent resistance, even under pressure caused by the blown-in insulation, which may generate mechanical stress. It is semi-transparent to simplify installation.
Recommended use: This product is intended for installation on the interior side of the building envelope and is guaranteed to withstand only indirect UV exposure for a maximum duration of 2 weeks.
Installation: Unroll the membrane and seal using tape such as: FLEXY BAND, SPEEDY BAND or EASY BAND.
Ensure that the overlap between the membranes is at least 15 cm to achieve an optimal seal.
To ensure correct and professional installation, the use of a nail sealing point is required.
Further details regarding installation can be found in the specific instructions provided by the supplier.
