Air barriers

This synthetic building wrap is made of non-woven polypropylene with a breathable layer. Airtight and waterproof, it blocks infiltration while allowing vapour to escape thanks to its breathable properties, thus preventing condensation and mould. It can be applied to various materials such as plywood, OSB panels, gypsum, brick, stucco, wood, or vinyl.

This 12" x 75' self-adhesive through-wall membrane provides continuous air- and water-vapor sealing for residential and commercial envelopes. At 40 mils (1 mm), it combines SBS-modified elastomeric bitumen with a trilaminated woven polyethylene facer. The self-adhesive backing speeds installation and supports consistent performance in all-weather conditions. Compatible with spray polyurethane foam insulation, it integrates cleanly into typical wall assemblies. Supplied in roll format, it offers efficient coverage for walls, flashings, transitions, and openings to help maintain a continuous air and vapor barrier across the enclosure.

Designed for wall assemblies and flashing transitions in residential and commercial applications, this self-adhered through-wall membrane provides continuous air- and water-vapor sealing. The 9" x 75' roll, 40 mil (1 mm) thick, is made of SBS-modified elastomeric bitumen with a trilaminated woven polyethylene facer, compatible with spray polyurethane foam insulation. It helps achieve clean, continuous transitions around openings, wall intersections, and other critical interfaces.

Designed for through-wall transitions and flashing details in residential and commercial applications, this self-adhered, all-weather membrane helps ensure reliable air- and water-vapor in wall assemblies. The 4" x 75' roll, 1 mm (40 mils) thick, is made of SBS-modified elastomeric bitumen with a trilaminated woven polyethylene facer that is compatible with spray polyurethane foam insulation. Supplied as a continuous roll with straight-cut edges, it integrates smoothly into typical building-envelope systems for new construction and renovation. An nominal 75 lb/in resistance provides a helpful reference during installation planning.

Seal through-wall transitions and flashing details with this self-adhesive air and vapor barrier membrane. Supplied as a 6" x 75' roll at 1 mm (40 mils) thickness, it installs in all weather conditions and helps maintain continuous air barrier performance for residential and commercial applications. Made of SBS-modified elastomeric bitumen with a trilaminated woven polyethylene facer, it is compatible with spray polyurethane foam insulation for high-performing assemblies. Designed for walls, openings and transitions, it provides reliable air and water-vapor sealing.

This self-adhesive through-wall membrane seals air and water vapor in commercial and residential building envelopes. The 18" x 75' roll is 1 mm (40 mils) thick and installs in all weather for fast, reliable performance. Made of SBS-modified elastomeric bitumen with a trilaminated woven polyethylene facer, it is compatible with sprayed polyurethane foam insulation, ensuring high-performance assemblies. The roll format simplifies application, creating continuous seals and clean detailing across at transitions.

Apply this wood waterproofing membrane as a protective, bonding undercoat before coatings. It rolls or brushes on smoothly and comes in an 11 L format suited to small and medium projects. Beyond surface prep, it can function as an air and vapor barrier on building walls and as a waterproofing layer in projects targeting better air and sound insulation. Suitable for renovations or new work, it supports reliable adhesion and consistent results for professionals and DIY users.

Designed for wood substrates, this liquid membrane creates a protective, bonding undercoat before applying additional coatings. It rolls or brushes on to form a uniform base and can also serve on building walls as an air/vapor barrier or as a waterproofing membrane when the project requires it. The 3.78 L pail offers a light gray/white matte finish suited to professional work and renovations alike.

Manage air movement and incidental moisture at exterior walls with this breathable building wrap. The non-woven polypropylene sheet includes a breathable coating and comes in a 9' x 100' roll for continuous coverage. Lightweight and easy to install, it’s suitable for both new construction and renovation projects. Tested to meet Canadian building code standards, this air barrier delivers reliable, professional-grade protection that ensures long-term performance and structural integrity.
