New product release: The hard-to-find VK Series Gray Structural Glazing Tape, ideal for curtain wall systems, is now available in custom cut sizes from Capital Tape Company.
VK Series Overview
VK Series Tape is available in black and now in gray, as seen below. The VK Series is used primarily within curtain wall systems to provide security and a virtually impenetrable barrier between the glass and frame. This remarkably versatile tape is made in the USA and is available from Capital Tape in standard and non-standard widths.
The VK Gray Structural Glazing Tape
The 1/4-inch thick, double-coated/double-sided VK Series gray structural glazing tape is a closed-cell PVC foam tape that is designed specifically for professional-grade structural glazing.
Extremely tough, dense, and virtually invincible, this tape’s low thermal conductivity significantly reduces heat transfer and prohibits water seepage and condensation on windows, doors, and metal systems. The VK gray glazing tape offers excellent resistance to weather, fungi, water, and oxidation. It’s the perfect choice for:
- Curtain wall structural silicone applications.
- Any application that relies on costly, high-density urethane gasketing for spacing, vibration, dampening or cushioning.
- Excellent adhesion to stainless steel, glass, aluminum, painted metal and vinyl.
Curtain Wall Structural Glazing
Curtain walls are typically constructed from aluminum or steel frames with glass panel infills and serve as an outer layer of a building to protect against external elements, though they do not bear any structural weight. Over time, the curtain wall industry has evolved with innovative designs and shifting environmental standards, resulting in a broad range of available products. For architectural glazing applications such as storefront glazing, Capital Tape provides a complete line of silicone-compatible glazing tape products, along with light-density PVC foams ideal for hollow metal and storefront glazing and for sealing gaps. Capital Tape’s compressible glazing tapes deliver the reliable support required for a variety of unique glazing systems.

The VK Series gray tape provides excellent adhesion to stainless steel, glass, aluminum, painted metal, and vinyl, and was developed for customers looking for a domestic product that delivers a cost-effective, professional alternative for their structural glazing needs.
