Emseal Closure

Expandable sealant is used to seal out dust, air, wind-driven snow and moisture through-out metal buildings, especially roofs.  Typical application would be at the ridge, peak cap, hip and ridge, end wall and pitch break.

AST is idea as a filler in expansion/compression joints subject to movement from thermal expansion and contraction, as as a gasket in mechanically fastened, non-moving applications such as lap seams.  AST is suitable for use against metal, plastic, wood, concrete, and other materials common in metal building structures.
