High Performance Construction Seam Sealing

Sheathing Tape 1640CW

1640CW is a permanent, high performance pressure sensitive tape solution for the seaming and sealing of joints in house wraps, sheathing materials, vapour barriers & foam insulation. It also provides instant repairs to ripped and torn construction films and membranes. It’s aggressive, UV-resistant solvent acrylic based pressure-sensitive adhesive is partnered with the flexibility and conformability of UV stabilized polypropylene film. This provides superior sealing and protective benefits, whilst offering ease of handling that are the characteristics of a high performance tape. 1640CW has exceptional temperature resistance, performing at sub-zero as low as -40ºC, through to 100ºC.
