Short Description

MasterSeal AWB 660 I air-/water-resistive barrier and Class 1 vapor retarder

Quantity Needed

MasterSeal AWB 660 I is a one component fluid-applied air/ water-resistive barrier that can also function as a Class I vapor retarder.

  • Based on Silica Fortified Rubber™ chemistry, this water-resistant, resilient membrane may be spray-, roller-, or brush-applied directly to approved above grade wall substrates.
  • It provides excellent secondary moisture protection behind most wall claddings including brick, siding, metal panels, EIFS and stucco.
  • Features of MasterSeal AWB 660 I air/water-resistive barrier and Class 1 vapor retarder
    • Approved for projects requiring Air Barrier Association of America (ABAA) performance specifications and quality assurance
    • Meets ASTM E2357, ICC-ES AC212 and ICC-ES AC148 requirements; fully qualified as an air/water-resistive barrier and flexible flashing material
    • ICC-ESR 3310 evaluation report confirms compliance with IBC, IRC and IECC requirements
    • Safe: water-based, low VOC and non-flammable
  • Benefits of MasterSeal AWB 660 I
    • As a liquid-applied, continuous membrane it eliminates seams, lap joints and staples; transmits wind load directly to the substrate
    • Silica Fortified Rubber technology offers strength, durability and self-sealing properties and require you to apply less material to achieve effective functioning
    • Can be applied at temperature at low as -4 °C (25 °F) when MasterSeal AWB 960 AC is added
    • MasterSeal AWB 660 I qualifies as both an air/water-resistive barrier and flexible flashing material because it meets ASTM E2357, ICC-ES AC212 and ICC-ES AC148 requirements
    • Applicator friendly, quick applying and fast drying; it can be spray-, roller-, trowel- or brush-applied at low wet-film thickness
    • Its textured surface allows sealants, adhesives and spray polyurethane foam to firmly bond to MasterSeal AWB 660 I
