EMSEAL MST Multi-use Foam Sealant Tape, Aluminum Gray, 1/4-in. Thick (expands to 1 in.) x 1-in. Wide, 6-Meter Reel - Moisture, Dirt, & Air Barrier for Metal Buildings & Joints

If you are looking for a sealant that's ideal for protecting metal roofs, window wells, AC window units, window casings, and similar joints and seams, this advanced, proprietary Sika EMSEAL AST Multi-Use Foam Sealant Tape is the perfect choice. Simply peel and place — the tape will expand to adjust to contours, gaps, and other varying surfaces for a tight, strong seal that keeps out moisture, air, dirt, dust, and other debris. And, it maintains that seal even if your surfaces expand or contract in response to increasing heat or cold. Tolerates temperatures as low as -40°F and as high as 185°F for a versatile, high-performance solution.
