Lightweight, hydrophobic polyester filter fabric with an attached polyproplene drainage matrix. Installed over VaproShield WRB/Air Barriers, it creates a positive drainage cavity behind cladding, promoting rapid drying of the building envelope.

Features

• Two depths: 3mm or 7mm
• Ideal for use with stucco or cultured stone
• Filter backing keeps drainage cavity clean during lath and plaster
• Easily works with traditional cladding systems such as metal panels, composite panels, and wood siding
• Increases building envelope drying capacity
• 3mm recommended for use in arid climates requiring minimum drainage and where cavity depth is restricted due to design constraints
• 7mm recommended for mixed climates and high humidity to maximize drainage and drying from liquid water and reverse vapor drive
