Tempered Glass Knowledge from Your New Jersey Glass Installer

Your Image Glass New Jersey glass installer stays updated on the local and Universal Building Codes that must be adhered to when it comes to commercial glass installation such as with glass doors and windows. Although they bring this knowledge with them to every project, it can be beneficial for commercial customers to understand the basics of why tempered safety glass is used and where in commercial installations.


Tempered glass goes through a manufacturing procedure that ultimately makes it as much as five times as strong as other forms of glass. The procedure involves heating the glass up, and then cooling it down rapidly. This process makes the glass stronger, and also changes the way the glass breaks. The glass shatters into small blocks that are much less likely to cause injury. That is why Tempered glass is also called Safety glass.

The building codes that control where and how tempered glass are installed include:

1. Glass in any door.
2. Glass in any kind of shower, bathtub area, hot tub, steam room, sauna or whirlpool area where the bottom edge of the glass is less than 60 inches above a standing surface and drain outlet.
3. Glass in fixed or operable panels adjacent to a door where the nearest exposed edge of the glazing is within a 24” arc of either vertical edge of the door in a closed position and where the bottom edge of the glazing is less than 60” above a walking surface.
4. Glass in fixed or operable panels that meets all of the following conditions:

  • Bottom edge is less than 18” above floor
  • Top edge is greater than 36” above floor
  • Total area of glass is greater than 9 sq. ft. (1296 sq.in.)
  • One or more walking surfaces within 36” horizontally of the glazing

5. Glass in walls used as a barrier for indoor or outdoor swimming pools or spas when both of the following exist:

  • The bottom edge of the glazing is less than 60” above a pool side of the glazing
  • The glazing is within 5 feet of a swimming pool or spa deck area

6. Glass in walls enclosing stairway landings or within 5 feet of the bottom and top of stairways where the bottom edge of the glass is less than 60” above a walking surface.
