Backer rods / Sealant cords

Backer rods are usually round, flexible lengths of foam that are used as a “Backing” in joints or cracks to help control the amount of sealant /caulking used and create a back stop. Different sizes/diameters are available for optimal fitting to the size of the joint being sealed. Beside shape, an important attribute is the variety of foam cell structure types: Closed cell, open cell and bi-cellular. It’s important to understand that cell structure makes a critical difference when it comes to irregular joint application, the desired flexibility in the joint, or sealant being used. The product is made of polyethylene foam, making it compatible with most common sealants or caulking.
The product is used in expansion and contraction joints to minimize the depth and amount of sealant used. It provides a backfill on building joints and this is characterized through its excellent compatibility with all standard sealing materials. It is used for vertical and horizontal joints in interior and exterior.
