Safety Glass Made Safer:
"Swing Bag" Tests Compare Glass Railing Performance
To compare the impact strength and post-break performance of glass railing systems, DuPont has conducted comprehensive "swing bag" testing of tempered glass and commonly specified laminated glass in varying thicknesses and structural systems.

Choosing a stronger laminated glass interlayer can have a significant impact on glass railing barrier post-break performance. Compare the lab videos below, to see how 35-mil SentryGlas® compares with 60-mil PVB in controlled side-by-side swing bag tests.
