Most innovative curtain-wall system or component
The M Resort Spa Casino in Las Vegas uses 3M VHB Structural Glazing Tape in its design.
An effective alternative to structural silicone and spacer tape for commercial curtain-wall applications, 3M VHB Structural Glazing Tape is made of acrylic foam. Suitable for indoor and outdoor applications, acrylic foam tape typically replaces liquid adhesives, spot welds, screws, rivets and other mechanical fasteners. The two-sided, pressure-sensitive, closed-cell acrylic foam is designed to bond to a wide range of substrates, including most metals, glass, many plastics, composites, sealed wood, paints and powder coatings. According to 3M representatives, 3M VHB Structural Glazing Tape offers the following performance benefits:
- It provides improved quality control due to consistent thickness and width
- The product comes fully cured from the tape manufacturer
- It bonds and seals simultaneously, and provides uniform stress distribution along the bond line
- The foam dampens vibration and reduces acoustic noise
- The tape’s 300 percent shear strain capability accommodates differential thermal expansion and contraction
- Viscoelastic characteristics give a proper balance of properties for reliability against wind, vibration and temperature changes
- The product is resistant to solvents, chemicals, UV and temperature cycling, and is backed by third-party testing documentation, i.e., ASTM Structural Performance Tests for Structural Glazing.
In addition, 3M VHB Structural Glazing Tape provides immediate handling strength; reduces the need for storage space since there is no cure time; eliminates spacer tape or gaskets, and the need for mix/ratio testing; requires minimal equipment; offers reduced installation time; and can be cut to fit any length, shape, size or profile, according to 3M officials. The tape has a clean crisp edge, and its appearance is enhanced by virtually invisible fastening, giving it a smooth and clean look. It is available in gray and black.
In the United States, prominent applications include Chicago’s O’Hare International Airport, Chicago’s Dearborn Center and The Walt Disney Concert Hall in Los Angeles.
