All-Purpose Foam Sealant Tape for Windows, Doors, & Metal Roofs/Buildings - EMSEAL AST, 5/16 in Thick (expands to 1 in) x 1 in Wide, 4-Meter Reel

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. 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.
