When Do Windows Have to Be Tempered?

Tempered GlassA big question we get quite a bit is when glass must be tempered based on code. Tempered Glass is the most affordable type of safety glass. Tempered Glass is created by heating the glass up to approximately 1200 degrees and then cooling it down rapidly. This process causes the glass to be 4 to 5 times stronger, and when it breaks, it will shatter into a million pieces, making it safer than large shards of glass.

So, what areas need to be tempered?

1. Glass in ANY door

2. Glass in any shower, bathtub area, sauna where the bottom edge of the glass is less than 60 inches above a standing surface. Basically: any window above a bathtub.

3. Glass in a fixed or operable panel adjacent to a door where the nearest edge is within 24″ of either vertical edge of the door.

4. Glass in a fixed or operable panel that is less than 18″ above the floor.
