Closed Cell and Non-Gassing Backer Rods

Backer Rod Installation Nomaco HBR® closed-cell polyethylene foam backer rod is used in concrete construction. HBR® acts as a barrier, limits the depth of cold-applied sealant required and prevents excessive sealant use. Nomaco SOF® Rod is a soft bi-cellular polyethylene foam backer rod used in concrete construction. It is comprised of both open and closed cells that will not out-gas when skin is ruptured and prevents sealant bubbling and failure. SOF® Rod has an outer skin and resilient interior network of cells and helps cold-applied sealants assume the optimum hour glass shape to prolong the sealant service life. You can either purchase cut-to-length or safe by purchasing by the full box.
