Capital Tape has expanded its line of high-performance structural spacer tapes with two new Silicone-Compatible Structural Spacer Tapes, the CT1826 and CT3200.
Designed for demanding structural glazing, curtain wall, gasketing, cushioning, and spacing applications, these silicone-compatible tapes provide manufacturers, glazing contractors, fabricators, and engineers with alternatives to traditional high-density urethane gasketing.
Both CT1826 and CT3200 Silicone-Compatible Structural Spacer Tapes are designed for use with structural silicone and offer excellent adhesion to common glazing substrates, including glass, aluminum, stainless steel, painted metal, and vinyl.
What Are Silicone-Compatible Structural Spacer Tapes?
Silicone-Compatible Structural Spacer Tapes are specialized foam tapes designed to provide consistent spacing between components while remaining compatible with structural silicone systems.
In structural glazing and curtain wall applications, spacer tape can help establish a controlled gap between substrates while also providing cushioning, vibration dampening, and temporary positioning during assembly.
Because the spacer becomes part of a larger glazing assembly, compatibility with the structural silicone used in the application is an important consideration. CT1826 and CT3200 are specifically designed for applications where silicone compatibility and dependable spacer performance are required.
New CT1826 Structural Spacer Tape
CT1826 is a dense, durable structural spacer tape designed for demanding applications involving structural silicone.
Its double-sided adhesive construction provides strong adhesion to a variety of common substrates, including glass, aluminum, stainless steel, painted metal, and vinyl. CT1826 is particularly well suited for curtain wall structural silicone applications and projects where high-density urethane gasketing has traditionally been used for spacing, vibration dampening, or cushioning.

Applications for Silicone-Compatible Structural Spacer Tape
These new Silicone-Compatible Structural Spacer Tapes are designed for a wide range of applications where controlled spacing and silicone compatibility are important.
Potential applications include:
Structural Glazing — Structural glazing systems require careful consideration of the materials used throughout the assembly. Silicone-compatible spacer tape can provide consistent spacing and cushioning while working alongside structural silicone.
Curtain Wall Systems — CT1826 and CT3200 are suited for curtain wall applications involving structural silicone, providing an alternative to traditional gasketing materials for appropriate applications.
Two- and Four-Sided Structural Glazing — CT3200 is designed for two- and four-sided structural glazing systems and can provide spacing and cushioning within these assemblies.
Gasketing and Cushioning — Both tapes can be considered for applications where high-density urethane gasketing is traditionally used for spacing, vibration dampening, or cushioning.
Glass-to-Frame Applications — The adhesive properties of these structural spacer tapes make them suitable for bonding and spacing applications involving common substrates such as glass, aluminum, stainless steel, painted metal, and vinyl.
