Product Details

  • Product #HE017

Air-Bloc 17MR is a liquid-applied, elastomeric membrane designed to provide a vapor-permeable air and water barrier when applied to above-grade wall assemblies. It is single component, water-based, and cures to a tough monolithic rubber-like membrane, which resists air leakage and water penetration. Air-Bloc® 17MR includes antimicrobial technology to create an integral mold-resistant membrane, and offers a broad application temperature range with proprietary fire resistance technology to achieve compliance with stringent NFPA 285 requirements.

  • Excellent adhesion to most construction surfaces such as exterior gypsum boards, CMU, concrete, stone, wood and metal
  • Excellent adhesion to most wall construction surfaces – can be applied to damp concrete
  • Meets highest industry performance standards
  • Vertical and lateral flame propagation: meets NFPA 285 Exception #2 per ASTM E1354 and ASTM E84

Air-Bloc 17MR is used in the construction of high-performance wall assemblies requiring vapor permeability in an air and water barrier. Air-Bloc 17MR is integrated with Henry® flashings and accessories as part of a complete wall system meeting the highest industry performance standards. Air-Bloc 17MR is commonly used on variety of wall substrates and sheathing prior to installation of exterior insulation and cladding.

  • Low temperature application down to 20°F (-6°C) with no additives required

  • Proprietary fire resistant technology provides superior fire performance with ASTM E1354

  • Seamless, vapor permeable elastomeric membrane for above grade walls

  • Easy, low cost spray application using simple equipment

  • Integral mold resistant formulation
