Norseal closed-cell foam tapes function as a gasket, forming a "seal" to prevent air, vapor, moisture and sound infiltration. A proper gasket will interface between two dissimilar surfaces. Unlike traditional sealing methods like caulks, mastics or pre-compressed materials, our foam tapes are easier to handle, compressible to create a superior seal, and will dampen vibration.
