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.
Description
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.

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.
It consists of a functional film and a polypropylene reinforcement and is designed for application on the inside of timber roofs and walls.
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.
