The Gerband SD Air Tight Membrane is a high quality air tight membrane that enables air tightness and vapour control.

This is used extensively in Ireland and typically used in walls and roofs.

In winter time it reliably prevents diffusion of interior humidity into the roof and wall construction and then in summer time it allows for back fusion from the insulation as well as the wall and roof construction.

This ultimately prevents condensation forming and it is this condensation that facilitates mildew growth and constructional damage.

This membrane is 1.5 metres wide by 50 metres long so gives a total coverage of 75m2.

Key features:

  • High quality air tight membrane that enables air tightness and vapour control
  • Used in walls and roof
  • In winter it reliably prevents diffusion of interior humidity into the roof and wall construction
  • In summer it allows for back fusion from the insulation as well as the wall and roof construction
  • This prevents condensation that facilitates mildew growth and constructional damages
  • 1.5m x 50m so a total coverage of 75m2
  • Double layered
  • 50 year warranty

The excellent ageing resistance of the Gerband SD Control air tight membrane means it will be reliable for years to come.

Gerband SD Control air tight membrane is best while being used indoors as a vapour barrier.

This is in order to build an airtight layer for the protection of the construction according to DIN 4108.

Carrier

  • Double-layered laminated film
  • Outstanding ageing resistance

Installation and application information:

  • 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 double-sided tape.
  • Gerband 586 or a suitable grommet should be used for penetrations.
  • For bonding barrier overlaps, penetrations and repair spots, Gerband 586 or a similar tape is recommended
  • For connections to concrete or masonry Gerband FORTAX 6400 is recommended.
  • Ensure there is a 100mm overlap of the membranes and tape with Gerband 586 or another suitable tape.
  • Ensure the corner overlaps are completely sealed.
