W. R. MEADOWS sheet and liquid-applied moisture barriers:

1. AIR-SHIELD_™
Self-Adhering Air/Vapor and Liquid Moisture Barrier

DESCRIPTION 
AIR-SHIELD self-adhering air/vapor and liquid moisture barrier is part of a total W. R. MEADOWS system to complete the building envelope. It is a roll-type product that is nominally 40 mils thick. The membrane’s controlled thickness is fabricated from cross-laminated polyethylene bonded to specially modified asphalt.This unique, self-adhesive membrane, protected by a special release paper, is strong and durable. It remains flexible when surface mounted and will adhere to most primed surfaces at minimum temperatures of 40° F (4° C). The membrane provides excellent protection as a tough barrier that won’t shrink, sag, dry out, crack, or rot. It offers excellent resistance to punctures during installation. The self-healing characteristics of AIR-SHIELD facilitate recovery if minimal damage is sustained under normal use applications, i.e. when penetrated with self-tapping screws or nails.

PACKAGING 
AIR-SHIELD is packaged in rolls of 38.5″ (.97 m) x 75′ (22.86 m). AIR-SHIELD can also be cut to desired width.

Optional sizes include:
4″ x 75′, 6″ x 75′, 9″ x 75′, 12″ x 75′, 16″ x 75′
18″ x 75′, 20″ x 75′ and 24″ x 75′.

2. AIR-SHIELD_™ LOW TEMP
Self-Adhering Air/Vapor and Liquid Moisture Barrier

DESCRIPTION
AIR-SHIELD LOW TEMP self-adhering air/vapor and liquid moisture barrier is part of a total W. 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. The membrane’s controlled thickness is fabricated from cross-laminated polyethylene bonded to specially modified asphalt.This unique, self-adhesive membrane, protected by a special release paper, is strong and durable. It remains flexible when surface mounted and will adhere to most primed surfaces at minimum temperatures of 20˚ F (-7˚ C). The membrane provides excellent protection as a tough barrier or flashing that won’t shrink, sag, dry out, crack, or rot. 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.

USES 
AIR-SHIELD LOW TEMP is designed for a variety of uses.  Primary applications include cavity wall and masonry wall construction. AIR-SHIELD LOW TEMP works equally well as an air, vapor, 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.

FEATURES/BENEFITS

• Low permeability – prevents the transmission of air and inhibits moisture vapor through porous building materials.
• Superior adhesion, even down to 20˚ F (-7˚ C).
• Cross laminated polyethylene film has excellent tensile strength, elongation, and tear resistance.
• Modified membrane is flexible at low temperatures.
• 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.
• Self-healing characteristics facilitate recovery if minimal damage is sustained under normal use applications.
• No flame required.
• Standard and extra-low temp versions also available.

PACKAGING 
AIR-SHIELD LOW TEMP is packaged in rolls measuring 38.5″ (.97 m) x 75′ (22.86 m).  AIR-SHIELD LOW TEMP can also be cut to desired width.

Optional sizes include:
4″ x 75′, 6″ x 75′, 9″ x 75′, 12″ x 75′, 16″ x 75′
18″ x 75′, 20″ x 75′ and 24″ x 75′.

3. AIR-SHIELD_™ LM
Liquid Membrane Air/Vapor and Liquid Moisture Barrier

DESCRIPTION
AIR-SHIELD LM is a single-component, liquid-applied, water-based, polymer-modified air/vapor and liquid moisture barrier. AIR-SHIELD LM cures to form a tough, seamless, elastomeric membrane, which exhibits excellent resistance to air and moisture transmission.

USES
AIR-SHIELD LM has been specifically formulated to act as an air/vapor and liquid moisture barrier within the building envelope.  It may be applied to most common surfaces and integrated into various wall systems.  AIR-SHIELD LM is suitable for both new construction and restoration.  Primary applications include cavity wall and masonry wall construction. AIR-SHIELD LM works equally well as an air and/or vapor 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, and plywood.

FEATURES/BENEFITS

• Low permeability – prevents the transmission of air and inhibits moisture and vapor from passing through porous building materials.
• Highly flexible – bridges cracks, which may form in the substrate.
• Environmentally compatible – AIR-SHIELD LM is non-toxic.
• User friendly – single-component, water-based technology allows for simple, safe application and easy cleanup.
• Liquid applied – simplifies detailing and assures a monolithic, seamless membrane when applied to a rough or smooth surface.
• Sprayable – with appropriately configured airless spray equipment – low application costs.
• Excellent adhesion – remains firmly bonded to the substrate, even when applied over damp
• VOC content is 0.0 g/L. Produces no harmful odors.
• Compatible with other asphalt-based emulsion products.
• May be applied to “green” concrete.
• Self-sealing – Nails and fasteners can be used without compromising performance.

4. AIR-SHIELD_™ LSR
Liquid Membrane Air/Vapor and Liquid Moisture Barrier

DESCRIPTION
AIR-SHIELD LSR (liquid synthetic rubber) is an asphalt-free, single-component, synthetic rubber based liquid air/vapor and liquid moisture barrier. AIR-SHIELD LSR cures to form a tough, seamless, elastomeric membrane, which exhibits excellent resistance to air and moisture transmission.

USES
AIR-SHIELD LSR has been specifically formulated to act as an air/vapor and liquid moisture barrier within the building envelope.  It may be applied to most common surfaces and integrated into various wall systems.  AIR-SHIELD LSR is suitable for both new construction and restoration.  Primary applications include cavity wall and masonry wall construction. AIR-SHIELD LSR works equally well as an air 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, and plywood.

FEATURES/BENEFITS

• Non-asphaltic – designed to meet stringent fire code requirements.
• Low permeability – prevents the transmission of air and inhibits moisture and vapor from passing through porous building materials.
