In today’s architectural landscape, striking design must blend seamlessly with structural integrity—and premium materials are essential. That’s where curtain wall glazing tape comes in: a high-performance solution that ensures durability, weatherproofing, and aesthetic appeal in modern building exteriors. Capital Tape Company has been at the forefront of this innovation for over three decades, supplying tailored glazing tape solutions for curtain walls and storefront systems.
What Is Curtain Wall Glazing Tape?
A curtain wall is a non-structural outer façade, typically constructed from aluminum or steel frames paired with glass infills. It protects a building from the elements without bearing load, relying on precise sealing and adhesion to perform effectively.
Curtain wall glazing tape plays a critical role here—serving as a gasket, thermal barrier, and adhesion layer. The right tape ensures:
- Aesthetic clean lines without bulky sealants
- Resistance to wind, water, and thermal cycling
- Vibration cushioning and long-term structural support
Why Capital Tape’s Glazing Tape Stands Out
1. Structural Spacer Tapes — VK Series
The VK Series is the core of Capital Tape’s structural glazing lineup. Made from closed-cell PVC foam and offered in heavy density, these tapes provide structural support while eliminating the need for urethane gasketing.
- VK1810: single-sided adhesive
- VK1826: double-sided adhesive
- Compatible with top-tier silicone systems (e.g., DOW, GE)
These tapes are extremely durable, virtually indestructible, and custom-cut in standard (¼”, ⅜”, ½”) and non-standard sizes (3⁄16″, 5⁄16″), with fast lead times: 1–2 business days for standard and 3–5 for custom cuts.
New: Gray VK Series Tape
A recent addition, the Gray VK Series offers all the heavy-duty benefits of the classic VK Series while providing a more visually neutral finish that blends with contemporary curtain wall aesthetics. This version features improved thermal resistance, low condensation, and enhanced weather, fungus, and oxidation resistance.
2. Compressible & Storefront Glazing Tapes
For storefront systems and lighter use cases, Capital Tape offers low- to medium-density PVC foam tapes that deliver flexibility without compromising seal integrity:
- CT510 Foam – low-density, single-sided PVC
- CT710 Foam – low-density, single-sided PVC with great acoustic dampening
- V1510 Foam – medium-density, AAMA-certified (810.1-92), PVC, single-sided
- V1526 Foam – medium-density, AAMA-certified, PVC, double-sided with plastic liner
These tapes are highly conformable and ideal for varying gap sizes and storefront glazing needs.
3. Protective Films for Curtain Wall Applications
Capital Tape’s protective films safeguard surfaces during fabrication, transit, or installation—especially useful for delicate glass or metal panels within curtain walls:
- CT309BU: medium-tack polyethylene film, up to 12 months outdoor use
- CT181: UV-stabilized polyolefin, pressure-sensitive, flexible, easy one-piece removal
- CT5335: heavy-duty, UV polyolefin with rubber adhesive for industrial substrates
These films protect against scratches, dirt, and UV exposure, then peel cleanly—crucial for preserving architectural finishes.
