QUICK OVERVIEW
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.
- 3mm, 7mm drainage matrix
- 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
