But times have changed.
New technologies have brought multiple fire-rated glass or fire-rated glass ceramic options that meet the required fire-resistance ratings without the unsightly wires blocking views and, more importantly, with the addition of impact resistance.
Traditional wire glass is not safety glass; if accidentally or intentionally impacted, the glass will shatter, likely leading to injuries. In fact, wire glass is no longer permitted in U.S. new construction except in rare occasions. In Canada, a movement is on to reform wire glass regulations, according to US Glass magazine.
According to the publication, the changes were spurred by a $5.5 million lawsuit after a secondary school student accidentally put his hand through a door’s wire glass instead of pushing on the pushbar. It’s one of several similar incidents around North America. With a multitude of clear, fire-rated glass options, the need for wire glass is practically nonexistent. Among Vetrotech’s many fire-rated offerings is its latest technology, Keralite Select, a glass ceramic that installs into standard fire-rated frames and doors, and comes in 20-, 45-, 60-, 90-, and 180-minute fire ratings.
Boasting superior clarity and sharpness, Keralite Select is the farthest thing from the aesthetics of a wire glass. Keralite Select has a color-rendering index of 97.1 (out of 100), the highest R96a value for glass ceramics, it has the lowest haze value at 0.5%, and bears no cloudy appearance even in variable lighting conditions.
Comparable to float glass in quality, the surface doesn’t have the “orange peel effect” common to standard fire-rated glass ceramics. In schools and other public buildings, the result is doors that are safe and secure—with a look that feels welcoming, not institutional.
