Soprema Sopraseal Stick 1100T – Self-Adhered Air & Vapour Barrier Membrane

The Soprema Sopraseal Stick 1100T is a self-adhered, elastomeric membrane designed to provide superior air, vapour, and water resistance for above-grade wall assemblies and roof transitions. Its robust SBS-modified bitumen composition ensures long-term durability and flexibility, even in harsh Canadian climates.

Key Features:

• Self-adhesive SBS bitumen membrane with polyethylene film facing

• Excellent adhesion to most construction substrates (gypsum, concrete, wood, metal)

• Cold-applied – no torching or primer required on clean surfaces

• Maintains flexibility in low temperatures

• Provides continuous air and vapour barrier for building envelope protection

• Meets or exceeds CAN/CGSB-37.58 and ASTM E2357 performance standards

Typical Applications:

• Exterior wall assemblies behind cladding systems

• Roof-to-wall and window-to-wall transitions

• Metal panel systems, masonry walls, and sheathing boards

Installation Guidelines:

• Apply to clean, dry surfaces above +10 °C for best adhesion

• Overlap seams by at least 2" (50 mm)

• Use roller pressure to ensure full contact and seal

• Store rolls vertically in a dry, shaded area
