DECK-O-FOAM expansion joint filler is a flexible, lightweight, non-staining, polyethylene, closed-cell expansion joint filler. It is a chemical resistant, ultraviolet stable, non-absorbent, low density, cost-effective, compressible foam that offers an extended service life in both interior and exterior applications. DECK-O-FOAM is supplied with a convenient, pre-scored removable strip to provide a uniform sealing reservoir in the joint.

It is compatible with all currently available cold-applied sealants.
