10mm Sure Cavity™

10mm Sure Cavity rainscreen drainage plane works because it maintains a separation between the materials used for the veneer and the structural back-up wall to drain incidental moisture and keep the building enclosure dry. 10mm Sure Cavity’s channels enable moisture that enters the building envelope to travel quickly down and out the bottom of the wall and provide a clear air gap for ventilation that won't compress like mesh based drainage matrix products.  10mm Sure Cavity meets Canadian code requirements.

Features & Benefits

• True channels conduct moisture to the bottom of walls faster than other products
• High impact polystyrene ensures durability and prevents compression, waviness, and nail drive-through experienced with fiber-based mesh products
• Saves installation time (half the time of furring strips and backer board)
• 96% post-consumer recycled content.
• The adhered fabric blocks mortar or stucco from filling the drainage channels and acts as a bug screen at the bottom

Protection from Incidental Moisture behind

• Stucco
• Thin Stone & Thin Brick
• Fiber Cement & Cedar Siding
• Brick
• Natural Stone

• Roll out 10mm Sure Cavity over the WRB on the backup wall with spunbond fabric facing the weather. Back wrap 4’’ fabric on bottom course to act as bug screen.
• Temporarily attach 10mm Sure Cavity with hammer stapler on wood backup walls or dabs of adhesive on masonry. 
• Roll out second and succeeding courses of 10mm Sure Cavity.  Overlap only the fabric.  Plastic butts directly to top of course beneath it.
• Install veneer – attachment of veneer material will sandwich 10mm Sure Cavity permanently in place in thin veneer applications.
