Q. I need advice on the type of glass to use in a residential elevator shaft. The openings are punched and will have removable stops. Can we use tempered glass or should we use a heat strengthened laminated glass? (Additional information: There are four (4) stories connected and this is an interior application. The glass panels are approximately 42&rdquo x 102&rdquo. Stairs surround the exterior of the elevator shaft and there is no fire resistant rating for the elevator shaft wall.)
A. Since you have indicated there is no fire resistance rating requirement for the elevator enclosure, the requirements for safety glazing would govern. Please note however that the only scenario I am aware of in which the walls of the elevator hoistway enclosure are not required to be fire-resistant rated is if the elevator hoistway occurs in an atrium that is separated from the remainder of the building, as required by the IBC. So let us take a look at 23 nice pictures jalousies and glass door curtain below.

Basically, the IBC will require all of the glass in the enclosure to meet the requirements of ANSI Z97.1 or CPSC 16 CFR Part 1201. This is glazing that is commonly referred to as safety glazing, and tempered glass is most commonly used to meet it.
