Nomaflex® is a closed-cell extruded polypropylene foam that is easy to handle and extends the service life of concrete by acting as an insulator for contraction and expansion joints. It is supplied in 5’ and 10’ lengths and 3-1/2” through 6” widths. For more information on Nomaflex and to view installation photos, click here.
Flat Rod™ is a closed-cell polyethylene foam expansion filler that is supplied with a convenient tear-off strip. When the tear–off strip is removed, it creates a void for the sealant in order to prevent surface cracking. Flat Rod is available in continuous lengths in wall thicknesses of 1/4” through ½” and widths from 1” through 6”. Click here for product sheet.
SOF® Rod is a bi-cellular polyethylene foam backer rod product. It is extremely flexible and can be used with cold-applied sealants. SOF Rod is non-gassing to prevent sealants from bubbling and failure. It is available in 3/8” to 4” diameter. Click here for product sheet.
HBR® is a closed-cell, polyethylene, foam joint filler that is used as a backing material for elastomeric and other cold-applied sealants. It helps the sealant assume the optimum shape to prolong service life and acts as a barrier to the flow of sealant through the joint. It will not absorb water and is available in ¼” to 6” diameter.
