GT Series

Material: GT Series Glazing Tape
Description: LAMATEK's GT Series Glazing Tape is used to seal glass into wood, aluminum and vinyl frames. The closed cell foam seals against air, moisture, dust and light penetration while serving to fill any irregularities in the sash extrusion. Our GT Series Glazing Tape also provides cushioning, vibration and shock absorbtion, thermal insulation, and sound deadening properties. This product also features good UV resistance.

All versions of our GT Series Glazing Tape have been AAMA* tested and approved by an independent testing lab. Copies of this approval, as well as test results, are available upon request.

*American Architectural Manufacturing Association (AAMA) 810.1-91 for Expanded Cellular Glazing Tape, Type 1.
