What Sure Cavity does:

  • The adhered fabric blocks mortar or stucco from filling the drainage channels and acts as a bug screen at terminations
  • It has superior appearance on thin veneers vs. furring strips due to less ridging, cracking, and waviness
  • It saves installation time (half the time of furring strips and backer board)
  • High impact polystyrene ensures durability, rigidity, and longevity
  • Vertical channels promote rapid drainage. Sure Cavity (and Gravity Cavity) are the only "True" channel drainage plane (drainage mat) products on the market today
  • Perforations allow cross-ventilation for better drying
  • Compartmentalized channels promote pressure equalization
  • It prevents bridging
  • Exceeds ASTM E-2273
  • UV Tested - Over 9 Weeks
