dblmattest23mm, 7mm (Black) VaproMat™ with attached Filter Fabric applied over WrapShield SA® WRB/AB creates a cost effective, positive drainage cavity.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
