Insul-Joint Expansion Joint Filler

Insul-Joint Expansion Joint Filler is a closed-cell, non-cross-linked polyethylene foam. Widely used in residential, commercial and industrial concrete construction applications, Insul-Joint is nearly ten times lighter than traditional expansion joint materials with the durability to prevent degradation over time. Its flexibility allows use on curves or columns without cracking or breaking. Easy to use and versatile with a peel top feature, Insul-Joint provides a cavity for sealants and can be used as a backer rod.
