Backer Rods

Written by 

This topic includes information related to backer rods installed during construction. Backer rods are round performed joint seals made from open or closed cell foam. They are used within joints between similar or differing construction materials to fill a joint or gap. A sealant is typically applied to open cell backer rods to prevent air or moisture infiltration, closed cell backer rods inherently deter air and moisture.
