Tyvek by DuPont is the industry-standard house wrap for residential and commercial building envelope construction across Canada. Available at Windsor Plywood, Tyvek housewrap and flashing tape products create a continuous weather-resistant barrier that blocks wind and moisture infiltration while allowing water vapour to escape from within the wall assembly. Proper installation of Tyvek at windows, doors, and penetrations is a critical step in preventing moisture damage, improving energy efficiency, and ensuring long-term structural performance in Canadian conditions. Windsor Plywood carries Tyvek HomeWrap and coordinating Tyvek Tape for a complete air and moisture barrier system.

Frequently Asked Questions
What Tyvek products does Windsor Plywood carry?
Windsor Plywood carries Tyvek HomeWrap house wrap and Tyvek Tape flashing tape. Tyvek HomeWrap is the industry-standard weather-resistant barrier for residential and light commercial construction across Canada. Tyvek Tape provides a matching self-adhesive sealing tape for seams, laps, and penetrations in the Tyvek air barrier system.
What does Tyvek house wrap do in a wall assembly?
Tyvek acts as a weather-resistant barrier (WRB) that blocks bulk water and wind-driven rain from infiltrating the wall assembly while allowing water vapour to pass through from inside the wall to the exterior. This outward vapour drive is an important part of wall drying potential in Canadian cold climates. Tyvek installed with properly lapped and taped seams creates a continuous air and water barrier behind the cladding.
How is Tyvek properly installed on walls?
Install Tyvek horizontally starting from the bottom of the wall, with each successive course lapping over the top of the course below by a minimum of 6 inches. Fasten with cap nails or cap staples at 12 to 18 inches on-centre into studs. Wrap and tape around window and door openings. Seal all seams, tears, and penetrations with Tyvek Tape. The installation sequence — bottom up with outward-lapping joints — ensures water drains out rather than into the assembly.
Does Tyvek need to be protected from UV exposure?
Yes. Tyvek has a limited UV exposure tolerance of approximately 120 days before UV degradation begins to reduce its performance. It should be covered with cladding within this window. If the exposure period is exceeded, inspect the Tyvek for brittleness and tears before closing it in. On large projects with extended exposure, contact DuPont for guidance on inspection and replacement requirements.
Can Tyvek Tape be applied in cold weather?
Tyvek Tape performs best when applied at temperatures above 4 degrees Celsius. At temperatures below this threshold, the adhesive becomes less effective and may not bond reliably to the Tyvek surface. For cold weather installation, warm the tape and the application surface before taping, and consider installing the tape prior to cold snaps when site conditions allow. Application temperatures should be confirmed with the Tyvek product documentation.
