Fastflex™ is a closed-cell polyethylene foam joint 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. Fastflex is available in continuous lengths in wall thicknesses of 3/8” and ½” and widths from 1” through 8”.
