CGT 6100
CGT 6100 is Cascade’s structural glazing tape, a high-density elastomeric PVC foam with dual-sided acrylic adhesive used as a semi-rigid spacer in two- and four-sided structural glazing. It is chemically compatible with all silicones and breathes so the silicone cures, bonds to glass, stainless, aluminum, painted metal and vinyl, and improves U-values by impeding heat transfer. Available in 1/8", 3/16" and 1/4" in black or grey on a 5-mil blue liner, cut to custom widths.
Made by Cascade Glazing Tape
Cascade Glazing Tape (CGT) is our own line of glazing and spacer tapes, slit in-house to the exact widths and thicknesses the glazing trade needs. From the CGT 1000 polyethylene glazing tape to the CGT 6100 structural spacer, CGT 1500 PVC foam and 1210G cap tape, it is the product Cascade Aqua-Tech was built on.
