Construction Specifier: Hazards of Traditional Wired Glass

Stairwell-aI haven’t posted much about traditional wired glass lately, but the hazard continues to be present in existing schools and other facilities.  I have an article on it in this month’s Construction Specifier in case you need a refresher.
