VBH™ structural glazing tape from 3M
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.
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 1
2 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 in2 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.
