The term “glazing tape” is frequently used throughout the residential and commercial window industry but it can mean very different types of products to different users. In the following blog, we will present the most critical information necessary to understand how structural glazing tape works for commercial applications, the typical physical properties, and the associated benefits.
3M™ VHB™ Structural Glazing Tapes
If you’re in the curtain wall, window wall, or storefront segment, the “glazing tape” you refer to could be a “structural glazing tape”. This type of tape uses a high strength, monolithic, foamed acrylic adhesive system that can bond an insulated glass unit into a metal framing system. The acrylic foam is viscoelastic and provides high elongation properties allowing it to effectively handle the varying loads of wind and weather.
3M™ VHB™ Structural Glazing Tape is a closed cell, double-sided acrylic foam tape that has the capability to develop very high bond strength and excellent long term holding power when bonded to a glass and metal framework. It was developed to replace structural silicone sealants in structurally glazed curtain wall,window wall, and commercial window units.
Construction
- Adhesive: High Performance Acrylic
- Adhesive Carrier: Conformable Acrylic Closed Cell
- Foam Thickness: 2.3 mm (0.090 in)
- Density: 720 kg/m3 (45 lb/ft3)
- Tape Color: Gray (G23F) or Black (B23F)
- Liner: 0.125 mm (0.005 in) Red Polyethylene Film Performance
Properties
The following technical information should be considered representative and should not be used for specification purposes.
- Peel Adhesion: 440 N/100 mm (25 lb/in width,stainless steel, ASTM D 3330)
- Normal Tensile: 480 kPa (70 lb/in, aluminum T-block, ASTM D 897)
- Dynamic Overlap Shear: 450 kPa (65 lb/in²,stainless steel, ASTM D 1002)
Key Benefits
If the proper procedures are followed, the benefits of using structural glazing tape are many. They include:
- More efficient processing: Immediate handling strength, no cure time, faster through-put and unit delivery. No mixing, curing, or liquid adhesives. Less than 5% waste, reduced labor costs, fewer process steps, and no equipment maintenance.
- Improved appearance: No color mismatching, streaking, or voids. Clean look from the interior side of the glass and consistent thickness and width.
- Reliable quality: Proven technology used in construction applications since the early 1980’s. Non-destructive testing with the ability to test all panels without deglazing.
