Tempered glass is a type of safety glass that has been heat-treated to be much stronger than regular glass. It is an important material in many applications because it can prevent injuries and damage.
In this article, we will explore when tempered glass is required, the reasons behind these requirements, and the benefits of using tempered glass.
When is Tempered Glass Required by Code?
Building Codes
In many countries and regions, building codes require the use of tempered glass in certain areas to ensure the safety of occupants. For example, in the United States, the International Building Code (IBC) and the International Residential Code (IRC) specify the requirements for tempered glass in different types of buildings.
Windows
Windows that are located in areas where there is a high risk of impact, such as near a doorway or in a child’s bedroom, must be made of tempered glass. This is to prevent the glass from shattering and causing injuries if someone accidentally runs into it or throws an object at it.where there is a high risk of impact, such as near a doorway or in a child’s bedroom
Doors
Glass doors, such as entry doors and patio doors, must also be made of tempered glass. This is because they are frequently opened and closed, and there is a greater chance of impact. Additionally, tempered glass provides extra security as it is more difficult to break than regular glass.
Wet Locations
In bathrooms and shower areas, tempered glass is required for shower doors, shower walls, and bathtub enclosures. This is because the glass is exposed to high levels of moisture and heat, which can cause regular glass to break. Tempered glass is more resistant to these conditions and can prevent accidents.
Structural Glass Panels
In some modern buildings, glass is used as a structural element, such as in glass floors or glass walls. In these cases, tempered glass is required to ensure the strength and stability of the structure. It can withstand the weight and stress of the building and prevent breakage.
Exceptions to Building Code Requirements
There are some exceptions to the building code requirements for tempered glass. For example, in some cases, regular glass may be used if it is protected by a safety film or if it is installed in a way that reduces the risk of impact. However, it is important to check the local building codes to determine the specific requirements for your area.
Safety Considerations
Injury Prevention
One of the main reasons for requiring tempered glass is to prevent injuries. When tempered glass breaks, it shatters into small, blunt pieces that are less likely to cause serious injuries. This is in contrast to regular glass, which breaks into sharp shards that can cause cuts and lacerations.When tempered glass breaks, it shatters into small, blunt pieces that are less likely to cause serious injuries.

Protection in Hazardous Situations
Tempered glass also provides protection in hazardous situations, such as during natural disasters or accidents. For example, in an earthquake, tempered glass is more likely to stay intact or break into small pieces that are less likely to cause injuries. In a car accident, tempered glass can prevent the occupants from being thrown out of the vehicle.
Applications and Tempered Glass Uses
Shower Doors and Enclosures
Tempered glass is commonly used for shower doors and enclosures because it can withstand the high levels of moisture and heat in the bathroom. It also provides a clean and modern look that is easy to maintain.
Patio Doors and Windows
In homes with patios or decks, tempered glass is often used for patio doors and windows. This is because these areas are exposed to the elements and are more likely to be impacted by wind, rain, or debris.
Automotive Windows
Tempered glass is used for the side and rear windows of vehicles. It provides protection for the occupants and helps to prevent the windows from shattering in an accident.
Furniture and Decor
Tempered glass is also used in furniture and decor, such as table tops, shelves, and picture frames. It adds a touch of elegance and sophistication to the design and is more durable than regular glass.
Benefits of Tempered Glass
Strength and Durability
Tempered glass is much stronger and more durable than regular glass. It can withstand impacts and stress without breaking, making it ideal for use in areas where there is a high risk of damage.
Heat Resistance
Tempered glass is also more resistant to heat than regular glass. It can withstand high temperatures without breaking or warping, making it suitable for use in ovens, stoves, and other appliances.
Safety
As mentioned earlier, tempered glass is safer than regular glass because it breaks into small, blunt pieces that are less likely to cause injuries. This makes it an ideal choice for use in homes, businesses, and vehicles.
Aesthetic Appeal
Tempered glass has a clean and modern look that can enhance the appearance of any space. It is available in a variety of sizes and shapes, making it a versatile material for use in different applications.
Exceptions and Alternatives
Laminated Glass
In some cases, laminated glass may be used as an alternative to tempered glass. Laminated glass is made by bonding two layers of glass together with a plastic interlayer. It is also a type of safety glass, but it has different properties than tempered glass. Laminated glass is more resistant to shattering and can provide better sound insulation.
Safety Film
Another alternative to tempered glass is safety film. Safety film is a thin, adhesive film that is applied to the surface of regular glass. It can help to hold the glass together if it breaks, reducing the risk of injuries. However, safety film is not as strong as tempered glass and may not provide the same level of protection.
Regular Glass with Protective Coating
In some cases, regular glass may be used with a protective coating. The protective coating can help to strengthen the glass and make it more resistant to impact. However, this is not a common practice and may not meet the building code requirements in some areas.
Conclusion
In conclusion, tempered glass is required in many situations to ensure the safety of occupants and prevent injuries. Building codes specify the requirements for tempered glass in different types of buildings and applications. It is important to understand these requirements and choose the right type of glass for your needs. If you have any questions about tempered glass or need further assistance, it is recommended to consult with a professional.
FAQs
What is the difference between tempered glass and regular glass?
Tempered glass is heat-treated to be much stronger than regular glass. It is also safer because it breaks into small, blunt pieces that are less likely to cause injuries. Regular glass, on the other hand, is more brittle and breaks into sharp shards.
Is tempered glass required for shower doors?
Yes, tempered glass is required for shower doors in most building codes. This is because shower doors are exposed to high levels of moisture and heat, and there is a greater risk of impact.
Can I use regular glass instead of tempered glass?
In some cases, regular glass may be used with a safety film or protective coating. However, it is important to check the local building codes to determine the specific requirements for your area.
How much does tempered glass cost?
The cost of tempered glass varies depending on the size, thickness, and type of glass. In general, tempered glass is more expensive than regular glass, but it is worth the investment for the added safety and durability.
How can I tell if glass is tempered?
Tempered glass usually has a mark or label on the edge or corner of the glass. You can also look for a small “tempered” or “safety glass” label on the surface of the glass. If you are unsure, it is best to consult with a professional.
