1/2" X-Seal™ Expandable Foam Tape - 32 ft. Roll

3/8" x 1/2" X-Seal™ Expandable Foam Tape - 32 ft. Roll

The versatility of Marco’s X-Seal™ makes it perfect for sealing any shaped gap in the construction of metal buildings, doors and windows, concrete, wood, and more. It has excellent compressibility and recovery (for minimal compression set) and its UV-stable design maintains a seal during thermal expansion and contraction of building panels. An ideal thermal and sound insulator, X-Seal is able to hold the exterior out and the interior in, while allowing vapors to move through. A hermetic seal allows the absorption of moisture and when conditions permit, the slow release of moisture through evaporation. With X-Seal, there’s no shrinkage or blow-out from closed-cell breakage, and no worry about drying out or becoming hard and brittle.

Expands to fill any-shaped gap in the construction of metal buildings, doors and windows, concrete, wood and more.
