Impact Resistance
The ability of a glass system to withstand impact from objects, human body loads, and wind-borne debris, tested per ASTM standards and building code requirements.
Technical Details
Impact resistance testing for glass railings follows ASTM E2353 (guard testing) requiring resistance to a 100 lb soft-body impact and 200 lb concentrated load at the top. For hurricane zones, ASTM E1996 large missile impact testing applies. Glass thickness, tempering, lamination, and support configuration all affect impact performance. The International Building Code references these standards for compliance.
Frequently Asked Questions
What impact tests do glass railings need to pass?
Glass railings must pass ASTM E2353 guard testing, including a 100 lb pendulum soft-body impact and 200 lb concentrated load at the top rail. In hurricane zones, additional ASTM E1996 large missile impact testing (9-lb 2x4 at 50 fps) is required.
