Understanding California Building Codes- When Tempered Glass is Mandated for Compliance

When is Tempered Glass Required by Code California?

Tempered glass, also known as toughened glass, is a type of safety glass that is five times stronger than regular glass. It is designed to shatter into small, rounded pieces rather than sharp shards, which can help minimize injury in the event of breakage. In California, the use of tempered glass is governed by various building codes and regulations to ensure the safety of its residents. This article will explore when tempered glass is required by code in California.

1. Shower Enclosures and Doors

One of the most common applications of tempered glass is in shower enclosures and doors. According to the California Building Code (CBC), tempered glass is required for all shower doors and enclosures. This is to prevent injuries that could result from glass shards in the event of a breakage. The CBC mandates that the glass must be at least 1/4 inch thick and meet specific safety standards.

2. Windows and Skylights

Tempered glass is also required for windows and skylights in certain situations. The CBC specifies that tempered glass must be used in windows and skylights located in rooms with a floor-to-ceiling height of 80 inches or more, as well as in windows and skylights within 18 inches of the top of a stairway. This is to ensure that in the event of a breakage, the glass will not cause serious injury.

3. Balconies and Railings

For balconies and railings, tempered glass is required to meet safety standards. The CBC mandates that the glass must be at least 1/4 inch thick and meet specific safety requirements. This is to ensure that in the event of a fall, the glass will not cause injury to the person falling or those below.

4. Storefronts and Doors

In storefronts and doors, tempered glass is required to meet safety standards. The CBC specifies that the glass must be at least 1/4 inch thick and meet specific safety requirements. This is to ensure that in the event of a breakage, the glass will not cause injury to pedestrians or employees.

5. Pool Fences and Enclosures

For pool fences and enclosures, tempered glass is required to meet safety standards. The CBC specifies that the glass must be at least 3/8 inch thick and meet specific safety requirements. This is to ensure that in the event of a breakage, the glass will not cause injury to children or pets who may be near the pool.

In conclusion, tempered glass is required by code in California for various applications, including shower enclosures, windows, balconies, storefronts, and pool fences. These requirements are in place to ensure the safety of residents and minimize the risk of injury in the event of glass breakage. It is essential for architects, builders, and homeowners to be aware of these regulations and ensure that tempered glass is used where required.
