Gerband sd vario membrane is a multi-layered vapour barrier with a moisture-variable sd value. It’s used indoors to create an airtight barrier and a vapour control layer for the protection of the construction in accordance with DIN 4108. During the winter it reliably prevents diffusion of interior humidity into the roof and wall construction. As a result, during summer it allows for back fusion from the insulation as well as the wall and roof construction. It also prevents condensation that causes mildew growth and structural damage.
Applications:
- Internal vapour control membrane.
- All construction types.
- Good for new builds and renovation of old buildings.
- Especially suited to timber frame and flat roof buildings.
Features & Benefits:
- Variable diffusion resistance.
- Moisture variable, sd value 0.25-5.0m.
- Composite of a functional PA film and PP non-woven.
- Outstanding ageing resistance.
- UV resistant: at least 18 months behind glass and three months in outdoor exposure*.
- Especially useful for new buildings as well as for renovation of old buildings.
- The CE sign according to DIN EN 13984 provides the necessary security for the application in constructions to build according to all valid requirements of the EnEV and construction standards.
