HDPE Protection/Barrier Courses

Continuous Spacer Shims

Arrow-Shim Extrusions are used recessed between sash and glass or plastic sheet in conjunction with a sealant cap bead. Arrow-Shim Extrusions are designed to control and provide proper face clearance cap bead spacing while providing a uniform cushion along the entire perimeter of the glass. Easier to install than round shims.
