Protect PWAB Party Wall Air Barrier

Protect PWAB (Party Wall Air Barrier)

Research has shown that Party wall cavities can allow a significant amount of air movement to move in the cavity causing associated loss of energy. To reduce this, the cavity is required to be effectively sealed. Protect PWAB Pack has been specifically designed to be airtight yet vapour open to achieve this requirement.

  • PWAB membrane is highly vapour permeable in excess of the minimum value required for wall membranes.
  • Completely water and airtight.
  • Lightweight and easy to install.
  • Available in a handy 300mm x 25m roll suited for timber frame party walls.
  • PWAB Pack includes the Protect Reinforced Universal Tape to make the air tight seal on the roll edges.
