NGA announces new Heavy Glass Door Design Guide

The National Glass Association (NGA) is proud to announce the publication of its newly updated Heavy Glass Door Design Guide, the guide replaces the previous 1999 edition

The Heavy Glass Door Design Guide is a must-have resource for architects, fabricators and contractors who require technical information and application suggestions for fully tempered and tempered laminated, heavy glass storefront and entrance system design.

“Since its original publication in 1999, the Heavy Glass Door Design Guide has served as an invaluable resource for those who utilize these products in their projects,” said Ron Biberdorf, Trulite Glass and Aluminum Solutions. “Frameless structural glass systems can enhance the efficiency of sustainable projects as well as create dramatic aesthetics, and this new edition reflects design trends and materials that will help ensure the continued growth and desirability of this industry segment.”

Structural guidance is provided on types of glass doors, hardware and entrance components; swinging, sliding door systems; top and floor-mounted systems; and application recommendations for fully tempered and tempered laminated glass entrance systems.

NGA’s Advocacy and Technical Director, Urmilla Sowell, added, “The inclusion of tempered laminated glass enhances the usefulness of the [guide] to reflect current industry trends and capabilities for heavy glass doors.”
