Insul-Joint is a closed cell (non-crosslink) polyethylene expansion joint filler designed to prevent cracks and breaks during concrete expansion and contraction. Insul-Joint can be used in all standard concrete construction, such as floor slabs, driveways, sidewalks, parking garages, highways and runways.

Insul-Joint is extruded from high quality closed cell polyethylene foam.
