CRL 7241XC3 Tremco POLYshim II Black Butyl Architectural Tape 1/8" x 3/8"

CRL 7241XC3 Tremco POLYshim II Black Butyl Architectural Tape 1/8" x 3/8"

CRL 7241XC3 Black 1/8" x 3/8" Tremco POLYshim II Butyl Architectural Tape is an essential component for high-performance glazing applications. This preformed butyl tape features 100% solids content and a continuous integral EPDM shim, ensuring superior adhesion and elasticity in various compression glazing systems, including curtain walls and sloped glazing. Designed to prevent sealant squeeze-out, the continuous rubber shim effectively absorbs pressure from building and glass expansion, minimizing the risk of glass breakage. With a hardness of 57 durometer Shore "00," POLYshim II remains flexible across a temperature range from -65°F to 200°F (-54°C to 93°C), making it suitable for diverse environmental conditions. This tape meets AAMA 800-92 specifications, ensuring compliance with industry standards. It is compatible with many glazing systems and is unaffected by ultraviolet exposure through glass, providing long-lasting performance. Each roll is 40 feet long and 0.15 inches thick, offering ample material for your projects. For optimal results, avoid using POLYshim II in continuous water immersion or at temperatures exceeding 200°F. With a case quantity of 20 rolls, this product is perfect for professionals seeking reliability and durability in their glazing solutions.

CRL Tremco® POLYshim™ II Tape is a 100 percent solids, highly adhesive and elastic, cross linked preformed butyl tape. Use it in compression glazing systems wherever the design calls for high performance glazing of curtain wall, unitized curtain walls, punched and ribbon window systems, and sloped glazing applications.


The continuous rubber shim works to prevent sealant squeeze-out because it is resilient to pressure exerted by building and glass expansion or contraction. It also helps prevent glass breakage by eliminating pressure points created by improper shimming. The continuous shim eliminates the need for preshimming the lite before installing the tape. Tremco® Pre-Shimmed tape has good adhesion, heat resistance, sealant compatibility, and resistance to weathering. It can be used in conjunction with many glazing systems.
