VAPOR 140
The VAPOR 140 vapour control membrane regulates the passage of moisture preventing the formation of interstitial condensation within the insulation package.
Description
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.

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.
Recommended use: direct UV protection is guaranteed. Installation is therefore permitted on both the internal and external sides of the building envelope.
Installation: Unroll the membrane and seal using tape such as: FLEXY BAND, FLEXY BAND UV, 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.
