Description

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 according to DIN 4108.

Gerband sd VARIO Membrane is a reliable airtight and vapour control layer. 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 facilitates mildew growth and constructional damages.

Carrier

  • 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*.

Color

  • White with print.

Special features

  • Fulfills the requirements of the EnEV as a moisture-variable vapour barrier,
  • 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.

Application

  •  Store in dry rooms from 5C to 25C, protected from UV-radiation,
  • The membrane should be applied perpendicular to the direction of the application surface i.e. studs, rafters and joists,
  • The membrane should be fixed with staples every 150mm or with PHS Double Sided Tape,
  • PHS Argo Joining Tape or a suitable PHS Grommet should be used for penetrations,
  • For bonding barrier overlaps, penetrations and repair spots, PHS Argo Joining Tape or a similar tape is recommended,
  • For connections co concrete or masonry PHS Internal Adhesive Sealant is recommended,
  • Ensure there is a 100mm overlap of the membranes and tape with PHS Argo Joining Tape or another suitable tape.
