While your windshield is made of laminated glass, your side and rear windows use tempered glass. This specialized material is engineered to keep you safer in an accident and make it easier to exit your vehicle in an emergency.
At Dixie Auto Glass, we use OEM-quality tempered glass for all side window replacements. Here is what you should know about why tempered glass matters.
Why It Matters
According to the National Highway Traffic Safety Administration, tempered glass significantly reduces the risk of serious cuts during a collision. The Car Care Council also explains that it shatters into small, blunt pieces that are less likely to cause injuries.
Understanding how tempered glass works helps you appreciate its important role in vehicle safety.
What is Tempered Glass?
Tempered glass is produced by heating standard glass to very high temperatures and then cooling it rapidly. This process creates internal tension that makes the glass:
- Four to five times stronger than regular glass
- More resistant to impacts and thermal stress
- Break into small, pebble-like pieces instead of dangerous shards
Why Side Windows Use Tempered Glass
- Safety: Reduces laceration injuries during accidents
- Emergency Egress: Can be broken quickly if occupants need to exit
- Cost-Effective: Easier and less expensive to manufacture and replace than laminated side glass
Tempered vs Laminated Glass
| Property | Tempered Glass | Laminated Glass |
|---|---|---|
| Strength | 4–5 times stronger than standard | Strong, with plastic interlayer |
| Break Pattern | Small blunt pieces | Cracks but stays in place |
| Typical Use | Side and rear windows | Windshields |
| Repairability | Must be replaced if broken | Can sometimes be repaired |
When to Replace Tempered Glass
Tempered glass cannot be repaired once it is cracked or shattered. If your side or rear window is damaged, it must be replaced with a new panel that meets OEM safety standards.
Common Questions About Tempered Glass
Can tempered glass be repaired?
No. It must be replaced when damaged because the strength is compromised.
Is tempered glass safer than regular glass?
Yes. It is stronger and breaks into small pieces that reduce injury risk.
Why isn’t tempered glass used for windshields?
Windshields require laminated glass to prevent ejection and maintain roof support in a rollover.
