DuPont™ Building Envelope Tape: Advanced Sealing Solution for Canadian Construction

February 4, 2026 Wilmington, DE — DuPont is pleased to announce the availability of DuPont™ Building Envelope Tape in Canada, providing superior protection and performance for residential and commercial buildings across the country.

Designed for Canadian Conditions

DuPont™ Building Envelope Tape is engineered to address the rigorous demands of Canadian climates. Its durable, UV-treated oriented polypropylene backing and strong acrylic adhesive can provide reliable sealing against moisture and air intrusion—even in extreme cold. The tape can remain pliable for a tight seal at low temperatures, making it ideal for Canada’s variable weather.

In Canada, DuPont™ Building Envelope Tape is a key component of the complete CAN/ULC S742 air barrier system when used with DuPont™ Styrofoam™ Brand XPS Insulation and DuPont™ Tyvek® Drain Wrap™ CA. This integrated system helps builders and contractors achieve code compliance and maximize energy efficiency.

Key Features and Benefits

• Superior adhesion: Tested to ASTM D3330, with a minimum adhesion of >35 oz/in.
• Strength & flexibility: Tensile strength of 30 lb./in minimum and 125% elongation for resilience.
• Weather resistance: Performs in temperatures from -40 °C to 104 °C; UV-resistant for long-term durability.
• Sustainability: Can enable repair of damaged foam insulation, helping to reduce material costs and job-site waste.
• Easy installation: Versatile and simple to apply. 

Supporting Canadian Builders

DuPont™ Building Envelope Tape is available in standard sizes (2.83 in. width, 180 ft. length, 24 rolls per case) and features a clear color for optimal visibility and aesthetic integration. Its robust construction and reliable performance make it an essential part of modern Canadian building practices.
