Air Tight Membrane - PHS Astra (75m2)

Passive House Systems Astra Air Tight Membrane

Key features:
  • Enables airtightness and vapour control in roof and wall constructions
  • Has an optimum fixed vapour resistance level of Sd 10m
  • Allows for an ideal level of vapour control, by preventing diffusion of internal vapour into the building envelope back in winter and allowing diffusion in summer
  • Prevents a build-up of condensed water vapour within the building envelope, that facilitates mildew growth and constructional damage
  • CE sign according to DIN 13984

This Air Tight Membrane from Passive House Systems (PHS) is the Astra membrane that comes in 75m2 rolls.

It enables air tightness and vapour control in roof and wall constructions.

It has an optimum fixed vapour resistance level of SD 10m and allows for an ideal level of vapour control by preventing diffusion of internal vapour into the building envelope back in winter and allowing diffusion in summer.

The Astra Membrane from PHS prevents a build-up of condensed water vapour within the building envelope, that facilitates mildew growth and constructional damage and features the CE sign according to DIN 13984.

Storage and usage:

  • 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 to concrete or masonry PHS Internal Adhesive Sealant is recommended
  • Ensure there is a 100mm overlap of the membranes and tape with Gerband 586
