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
  • Perforations allow cross-ventilation for better drying
  • Compartmentalized channels promote pressure equalization
  • It prevents bridging
  • Exceeds ASTM E-2273
  • UV Tested - Over 9 Weeks
How to Install Sure Cavity
  • Position Sure Cavity™ with the spunbond fabric facing to weather with 4" fabric skirt wrapped back under bottom on first course.
  • Spunbond fabric 4" skirt should overlap the top of the lower course of Sure Cavity™.
  • Construction paper, Sure Cavity™ and metal lath to extend down over top of foundation wall a minimum of 2".
