R. MEADOWS system to complete the building envelope. It is a roll-type product that is nominally 40 mils thick and is ideal for cold weather applications.\u00a0 The membrane&#8217;s controlled thickness is fabricated from cross-laminated polyethylene bonded to specially modified asphalt.<\/p>\n<p>This unique, self-adhesive membrane, protected by a special release paper, is strong and durable.\u00a0 It remains flexible when surface mounted and will adhere to most primed surfaces at minimum temperatures of -7\u00ba C. The membrane provides excellent protection as a tough barrier or flashing that won&#8217;t shrink, sag, dry out, crack, or rot.\u00a0 It offers excellent resistance to punctures during installation. The self-healing characteristics of AIR-SHIELD LOW TEMP facilitate recovery if minimal damage is sustained under normal use applications, i.e. when penetrated with self-tapping screws or nails.<\/p>\n<p><strong>USES<\/strong><br \/>\nAIR-SHIELD LOW TEMP is designed for a variety of uses. Primary applications include cavity wall and masonry wall construction.\u00a0 AIR-SHIELD LOW TEMP works equally well as an air, vapour, and liquid moisture barrier on precast concrete, cast-in-place concrete, masonry (concrete block), interior and exterior gypsum board, Styrofoam, primed steel, aluminum mill finish, anodized aluminum, primed galvanized metal, drywall, plywood, and OSB.<\/p>\n<p><strong>FEATURES\/BENEFITS<\/strong><\/p>\n<ul>\n<li>Low permeability &#8211; prevents the transmission of air and inhibits moisture vapour through porous building materials.<\/li>\n<li>Superior adhesion, even down to -7\u02da C.<\/li>\n<li>Cross-laminated polyethylene film has excellent tensile strength, elongation, and tear resistance.<\/li>\n<li>Modified membrane is flexible at low temperatures.<\/li>\n<li>Excellent adhesion to prepared substrates of precast concrete, cast-in-place concrete, masonry (concrete block), interior and exterior gypsum board, Styrofoam, primed steel, aluminum mill finish, anodized aluminum, primed galvanized metal, drywall, and plywood.<\/li>\n<li>Self-healing characteristics facilitate recovery if minimal damage is sustained under normal use applications.<\/li>\n<li>No flame required.<\/li>\n<li>Standard and extra-low temp versions also available.<\/li>\n<\/ul>\n<p><strong>PACKAGING<\/strong><br \/>\nAIR-SHIELD LOW TEMP is packaged in rolls measuring 0.97 m (38.5&#8243;) x 22.86 m (75&#8242;).\u00a0 AIR-SHIELD LOW TEMP can also be cut to desired width.<\/p>\n<p>Optional sizes include 10.1 cm (4&#8243;), 15.2 cm (6&#8243;), 22.8 cm (9&#8243;), 30.5 cm (12&#8243;), 40.6 cm (16&#8243;), 45.7 cm (18&#8243;), 50.8 cm (20&#8243;) and 61 cm (24&#8243;), all 22.86 m (75&#8242;) long.<\/p>\n<p><strong>COVERAGE<\/strong><br \/>\nCoverage is approximately 22.3 m\u00b2 (240 ft.<sup>2<\/sup>). Net coverage when lapped 63.5 mm (2.5&#8243;) is 20.9 m\u00b2 (225 ft.<sup>2<\/sup>).<\/p>\n<p><strong>STORAGE<\/strong><br \/>\nAIR-SHIELD LOW TEMP should be stored palletized and protected from rain and\/or physical damage.\u00a0 Do not store at temperatures above 32.2\u00b0 C for extended periods of time.\u00a0 Do not leave membrane exposed to direct sunlight. Do not double-deck pallets.\u00a0 Store away from sparks or flames.\u00a0 Outdoors, store AIR-SHIELD LOW TEMP on pallets and completely cover.<\/p>\n<p><strong>SPECIFICATIONS<\/strong><\/p>\n<ul>\n<li>Meets CAN\/CGSB-51-33, Type I Water Vapour Permeance Requirements<\/li>\n<li>2015 National Building Code of Canada<\/li>\n<li>ABAA Section 07261 Self-Adhering Air and Vapour Barrier Specification<\/li>\n<\/ul>\n<p><strong>MAINTAIN ENERGY EFFICIENCY<\/strong><br \/>\nAIR-SHIELD LOW TEMP provides an effective barrier to air exfiltration and infiltration, reducing condensation within the wall assembly and increasing efficiency of a building&#8217;s mechanical system.\u00a0 Wet insulating materials lose much of their &#8220;R&#8221; factor performance characteristics, reducing the energy efficiency of the structure.\u00a0 W.

Strike masonry joints flush. All walls to receive AIR-SHIELD LOW TEMP must be capped to prevent moisture infiltration from entering the wall during construction. Concrete surfaces must be smooth and without large voids, spalled areas, or sharp protrusions. Concrete must be cured a minimum of 14 days and must be dry before AIR-SHIELD LOW TEMP is applied. Where curing compounds are used, they must be clear resin-based, without oil, wax, or pigments.<\/p>\n<p><strong>Surface Conditioning <\/strong><strong>\u2026<\/strong> All surfaces to which AIR-SHIELD LOW TEMP is to be applied must be addressed.\u00a0 <a href=\"https:\/\/can.wrmeadows.com\/en-ca\/mel-prime-wb-canada\/\">MEL-PRIME<sub>\u2122<\/sub>\u00a0W\/B<\/a> water-based adhesive can be used when temperatures are above 4\u00ba C.\u00a0 Use <a href=\"https:\/\/can.wrmeadows.com\/en-ca\/mel-prime-canada\/\">MEL-PRIME<\/a> adhesive in colder weather and at higher application temperatures for maximum adhesion. MEL-PRIME may be applied with a roller to an area that is to be covered the same day. Uncovered areas must be re-applied with MEL-PRIME the next day. See product container for complete application, drying information, and precautions.<\/p>\n<p><strong>Application Method \u2026<\/strong> AIR-SHIELD LOW TEMP can be applied at minimum temperatures of -7\u00ba C.\u00a0 Apply membrane to addressed surface by removing the release paper and rolling the membrane firmly into place. Remove the release paper only as the membrane is being applied. Ensure the membrane is fully adhered and remove all wrinkles and\/or fish mouths.\u00a0 Cut the membrane with a utility knife to detail around protrusions and masonry reinforcing. Seal all end laps and protrusions with <a href=\"https:\/\/can.wrmeadows.com\/en-ca\/pointing-mastic-canada\/\">POINTING MASTIC<\/a>. Overlap subsequent courses of membrane a minimum of 63.5 mm (2.5&#8243;).
