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
