Dynamic Loads (Deadload Support)
With a design strength of 12 PSI (85 kPa), 3M™ VHB™ Structural Glazing Tapes are used for dynamic tensile or shear loads (such as windloads). Established with material property testing, as well as ASTM dynamic load testing the design provides a safety factor of atleast five and used in curtain wall applications.
Static Loads (No Deadload Support)
3M™ VHB™ Structural Glazing Tapes for static tensile of shear loads (such as dead weight loads, snow loads and other long term loads) uses a design strength of 0.25 PSI (1.7 kPa). To provide a safety factor of at least five 4 in2 of tape per pound of load must be used to support static loads.
Important: Dynamic and static load calculations should be performed on unsupported deadload structural glazing applications. For application, ensure the output of the wider tape width is used as the appropriate tape width.
