Valley & Hip Sealer 3/4"X1"X19'10.2"

Emseal metal roof and building sealants are self-adhering tape seals made from resilient, open-cell polyurethane foam impregnated with a water-based acrylic-modified asphalt emulsion (AST Hi-Acrylic).  They replace and outperform liquid sealants, butyl-tape sealants and closed-cell closures.

The open-cell foam is impregnated, compressed  and shipped in reels. The stored strain-energy of compression in the foam means continuous back-pressure is exerted against surfaces to be sealed. This pressure, combined with the adhesive nature of the impregnation, assures reliable adhesion to both substrates. As the sealed components shrink and expand with seasonal temperature changes, long-term sealing contact with the substrates is maintained.

Seal out dust, air, wind-driven snow, and moisture through joint details in metal buildings and similar structures, both pre-manufactured and site-built.

Ideal as joint fillers in expansion/compression seals in joints that are subject to movement from thermal expansion and contraction of a structure, and as gasket-type seals in mechanically fastened, non-moving applications such as lap seams.

Suitable for use against metal, plastic trim, and other materials common in metal building structures.

Use in all applications where the material will be allowed to expand to fill voids.

Provides a durable and versatile solution to these typically difficult-to-seal panel contours at eaves, hips, valleys, peaks, concealed gutters, etc.

Use small-sizes in flat-on-flat “gasket” applications (side laps, end laps, valley, hips and laps with closures) where the material will be held at a high degree of compression by fasteners such as clips, screws, etc.

In gasketing applications Emseal metal roof and building sealants are hard-working, long-lasting, high-performance alternatives to butyl-tapes which generally squeeze out; or to closed-cell materials which suffer compression set and additionally tend to dry out and crumble.
