Closure-Foam™ is economically priced without sacrificing quality. Our crosslink polyethylene foam has a unique coating that gives it better UV resistance and better durability than the industry standard. Independent testing confirms Marco's 1.5 density foam provides better UV stability than competitive products with a 2.0 density.

Designed to stay put, Marco's M63 industrial adhesive eliminates installation blow-away problems. The generous 1/4” adhesive bead can be applied to either the flat or the ribbed side of Closure-Foam, and it even adheres in subfreezing temperatures and on wet surfaces.

Closure-Foam is most commonly used without dovetails but is also available with interlocking dovetails (with or without adhesive) to eliminate gaps and ensure a snug end-to-end fit. They ship pre-scrapped leaving you with less job site cleanup.
