Sure Cavity™ Rainscreen Drainage Plane

SC5016, SC5032

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

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™. Only the fabric overlaps the course below (the top of the lower corrugated polystyrene sheet abuts the bottom of the upper corrugated polystyrene sheet).
• WRB, Sure Cavity™ and metal lath to extend down over top of foundation wall a minimum of 2".
