5-Pack - All-Purpose Foam Sealant Tape for Windows, Doors, & Metal Roofs/Buildings - EMSEAL AST, 1/2 in Thick (expands to 2 in) x 1 in Wide, 4-Meter Reel

A high-quality alternative to typical lightweight weather-stripping tapes.All-Purpose-Sealant Tape from EMSEAL is a robust, self-expanding, asphalt-infused foam product that seals where others don’t and offers durability far in excess of cheaper alternatives.

• Used to seal out dust, air, wind-driven snow, and moisture through joint details in metal buildings and similar structures, both pre-manufactured and site-built.
• UV-stable; will not dry out and become hard and brittle; seals gaps.
• Conforms to contours and fills gaps; will not extrude from between joints like caulk or butyl-tapes; good thermal and sound insulator.
• Excellent compressibility and recovery; maintains a seal during thermal expansion and contraction of building panels; no shrinkage or blow-out due to closed-cell breakage.
• Supplied with adhesive on one side. After removal of packaging, begins gradual expansion, more slowly in cold weather than in hot.
