COCON 20 SD NT
ATTICS AND TIMBER FRAMES
VAPOR BARRIER SCREEN
The COCON SD 20 NT Vapor Barrier is a technical screen with high mechanical strength designed to provide long-lasting protection for insulation and wall structures.
It performs two essential functions: it is both airtight and water vapor-proof with an Sd value = 20 m. Its robust design ensures reliable installation for long-term insulation.
It is ideally suited for use in converted attics, unconverted attics, as well as for timber frame walls with ventilated exterior cladding.
APPLICATION FOR ATTICS AND TIMBER FRAMES
This versatile product is perfectly suited to the following configurations:
- Converted attics.
- Unconverted attics.
- Timber frame walls with ventilated exterior cladding.
- Indoor use only.
PERFORMANCE AND TIGHTNESS
Sd 20m
Its Sd value of 20 meters ensures optimal regulation of water vapor diffusion through the wall.
High mechanical strength
Designed to withstand the stresses of installation and preserve the integrity of the wall.
Vapor-tight
By blocking water vapor migration, it protects the insulation from moisture.
COMFORT AND ECO-RESPONSIBILITY
Airtight
Its airtightness actively helps eliminate heat loss through air leakage.
Recyclable
The COCON SD 20 vapor barrier has a reduced environmental impact, with a composition made of 65% bio-based material.
