Requirements For Safety Glass

Safety glass is required when the window measures more than 9 feet, the bottom is more than 18 inches from the floor, the top is more than 36 inches from the floor, or there is a floor within 36 inches of the glass. However, safety glass is an International requirement in all doors regardless of measurements.

Annealed Glass

Annealed glass, often called standard glass, is a soft glass that is created by thermally heating glass and slowly controlling the way it cools down. Annealed glass breaks into long shards, which can cause injury.

Tempered Glass

Tempered glass is an extra-strong glass that cannot be cut. Tempered glass is made by taking annealed glass that is already cut to a desired size, then heating it up and cooling it quickly. Tempered glass is resistant to breaking. It shatters into small pieces, to help prevent injury.

Laminated Glass

Laminated glass is two pieces of glass laminated together. Laminated glass holds together when shattered. It may break into shards, but it will stay together within the frame.

Wired

Wired glass is a fire-resistant glass commonly used in commercial buildings such as schools or hospitals. It is not traditionally used in residential buildings.

Fire-Rated Glass

Fire-rated glass is glass that is specially treated to withstand fire. It is rated by the amount of time it can withstand fire.
