Description

BlazeFrame® Perimeter L-Bead-INT is PVC blended with an intumescent fire retardant polymer composite. With the intumescent already in the bead, there is no need for extra tape making this a lower cost assembly. BlazeFrame® Perimeter L-Bead-INT is easily attached with staples through the bead flange. Multiple perforations along the 1-1/8" flange enhance strong compound adhesion and the raised shoulder provides a ground for a flush finish. Rigid vinyl is rust proof, dent resistant and easy to field cut without distorting the profile.
