Safety glazing is a feature for some types of glass like windows and shower doors that make the glass harder to break, as well as safer when broken. The benefit of safety glazing is that it reduces the risk of glass breaking and reduces the danger caused by broken glass. Safety glass is used in some applications, including commercial glass, automobile applications, bathrooms and shower glass, and other glass doors, windows, and shopfronts. Here we look at what constitutes safety glazing and when you might need it for your glass installations.

What is Safety Glazing?
Safety glazing is the process used to make glass less susceptible to breakage, and less dangerous when broken. While there are several different types of safety glazing, the two most common types are tempered glass and laminated glass. Tempered and laminated glass are both required to be permanently labeled indicating their glazing type, usually by etching in the corner.
Tempered glass is processed by controlled chemical or heat treatment to increase strength when compared to standard glass. Tempered glass balances the internal stresses on the glass, and causing the glass to break into small pebble-like pieces when shattered, rather than sharp panes.
Laminated glass consists of layers of glass and plastic held together by a binding interlayer. Laminated glass is also usually tempered to avoid the formation of dangerous shards, while the interlayer also prevents glass fragments dispersing.
Places Where You Need Safety Glazing
In addition to the criteria set above, certain situations require safety glazing according to minimum standards set by the International Residential Building Code. If the codes if you state differs at all to this, it’s important to keep in mind that the stricter code applies.
The sites in your home or business that require safety glazing include:
- Glass side hinged doors including storm doors
- Glass sliding doors, in both fixed and sliding panels
- Glass bifold and sliding closet doors
- Glass shower doors and shower enclosures or steam shower enclosures, hot tubs, whirlpools, saunas, and bathtubs whenever any glass including windows is within 60 inches vertically from any standing surface
- Glass in fixed or moving panels within 24 inches of either edge of the door and less than 60 inches above floor
- Glass railings
- Glass walls, glass fences and glass pool enclosures for indoor and outdoor pools within 60 inches of walking surface
- Glass walls in staircase landings within 60 inches of the top or bottom of the stairs and above the walking surface
When Do I Need Safety Glazing?
The codes that define where safety glazing needs to be installed are strictly enforceable by law. Other homeowners and contractors may misunderstand that Safety Glass Codes only apply to new houses, but this is not the case. The codes are enforceable for new, old and remodeled homes.
Codes for Safety Glazing
Safety glazing is required for any fixed or operable panel of glass that meets these criteria:
- Exposed area of an individual pane greater than 9 square feet.
- Exposed bottom edge less than 18 inches above the floor.
- Exposed top edge greater than 36 inches above the floor.
- One or more walking surfaces within 36 inches horizontally of the plane of the glazing.
Ensuring you have the right safety glazing in your home or business is essential to meet strict building codes and keep your buildings and occupants safe.
