Structural Glazing Tape...
success in thousands of buildings since 1990
Durable for
ongoing confidence
Eye appeal from a
distance and even up
close from the inside
and out
Simplified
application saving
time and materials
• Clean edge lines
• Tape bonds, seals and conforms
to a variety of surfaces
• Color remains consistent from one
end to the other
• No color change as seen between
structural silicone and spacer
tape/gasket
Reliability
guaranteed
• Up to 20-year warranty for
qualifying applications
• Bonds with excellent dynamic
strength to replace wet glazing
• Resists environmental conditions
such as UV, moisture, heat,
and cold
• Viscoelasticity absorbs shock and
allows movement for reliability
against wind, vibration, and thermal
expansion/contraction
• Speeds assembly and delivery
• Bonds on contact with no drying,
fixturing, and liquid mess
• Saves the time, labor, and materials
of spacer tape, gasketing, masking,
and clean-up
• Eliminates the time and testing of
2-part systems for glass/butterfly,
snap time, and mix ratio

Application Guidelines
3M
™
VHB
™
Structural Glazing Tape is a two-sided pressure sensitive adhesive acrylic foam tape designed to
bond glass to metal frames in glass curtain wall systems. Each application will be reviewed on a project specific
basis. Application guidelines will be based upon adhesion test results generated by 3M Technical Service. These
project specific application guidelines will be provided to the customer and must be followed during the glass
bonding process.
Design Guidelines
Note: For tape area calculations, the following guidelines can be used. Please ensure that each project is
reviewed and approved by your local 3M Technical Service representative.
Dynamic Loads (deadload support)
For dynamic tensile or shear loads (such as windloads), a design strength of 12 psi (85 kPa) is used for 3M
™
VHB
™
Structural Glazing Tape. This design strength provides a safety factor of at least 5 and was established
based on material property testing as well as ASTM dynamic load testing for curtain wall applications.
Static Loads (no deadload support)
For static tensile or shear loads (such as dead weight loads, snow loads, and other long-term loads), a design
strength of 0.25 psi (1.7 kPa) is used for 3M
™
VHB
™
Structural Glazing Tape. This means 4 in
2
of 3M
™
VHB
™
Structural Glazing Tape per one pound of load should be used to support static loads. This guideline provides a
safety factor of at least 5.
Important: Dynamic and static load calculations should be performed on unsupported deadload structural glazing applications.
The calculations resulting in the wider tape width should be used as the appropriate tape width for the application.

Tape for Architectural Panels
For more than 20 years, engineers
worldwide have been specifying 3M
™
VHB
™
Tapes to permanently bond and
seal architectural panels. In commercial
construction from Australia to Brazil,
the United States to the United Arab
Emirates, applications have continued
to expand indoors and outdoors for
panel to frame bonding and stiffener
attachment.
