Closure-Foam™ comes in more than 450 standard profiles and custom sizes that are easy to order. Designed to stay put, Marco’s M63 industrial adhesive eliminates 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.

Closure-Foam is economically priced without sacrificing quality. Marco’s 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.
