Revolving doors are an aesthetic feature of a building entrance, as well as a practical solution from an energy efficiency perspective. Both traditional manual-style and automatic revolving doors offer a range of material choices, including polished or brushed stainless steel, brass or bronze finishes.
Curved tempered glass or laminated glass can be specified for the doors themselves and the “wings” (panels around the central shaft of the door). Originally, the federal safety glazing regulation exempted curved glass in revolving doors from meeting its impact requirements. The standard, CPSC 16CFR 1201, which was adopted in 1977, included an impact test requirement for flat glass. There were no provisions for curved glass testing.
Today, a harmonized ANSI standard ANSI Z97.1, does include testing information for curved glass. In general, both monolithic tempered and laminated glass meet the safety glazing requirements of these standards. The key difference between the two products is evident upon breakage. Tempered glass typically falls out of the frame in small particle sizes. Broken glass sticks to the inter layer if the glass is laminated. In both cases, immediate glass replacement is required.
