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.  10mm Sure Cavity’s channels are better than fiber-based mesh because they enable moisture that enters the building envelope to travel quickly down and out the bottom of the wall.  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)
• Provides LEED credit value with its 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

• 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.
