Automotive Side Window Repair FAQs

Laminated side glass gives you more opportunity to repair breaks.

For several decades, tempered glass has been used for side windows on vehicles. As glass technology advances, many automakers are now switching to laminated glass making side window repair possible.

How is laminated side glass different from the glass in a windshield?
Laminated side glass is thinner than windshield glass. Side glass is usually 3.8mm whereas windshields are between 4 and 5mm thick.

Why is this type of glass now being used on vehicles?
A federal mandate will require all cars to have ejection protection during a roll over by 2018 and laminated glass conforms to this standard. In addition, laminated side glass offers the following benefits:

  • Blocks 99% of ultraviolet rays.
  • Keeps the interior cooler, allowing less usage of the AC which saves fuel.
  • Allows for a quieter ride as it blocks more road noise than tempered glass.
  • Protects from outside projectiles and occupant ejection during accidents.
  • Acts as a theft deterrent.

Can I do a repair on the laminated side glass of a vehicle?
Yes, it is possible to repair a break on the side glass of a vehicle. However, the side glass is more vertical than the windshield which can make repairing it a bit more challenging. Also, many side windows contain a film which also must be taken into consideration.

What is the process for repairing side glass?
The process is the same as repairing a break on a vertical windshield. If you are using the ecoVac™, G3™ or ProVac 2000™ injector, the ProVac Vertical Adapter gives you the ability to perform this type of repair.

How can I tell if the side glass is laminated or tempered?
If there is damage, especially a bull’s-eye, star or combo break, then you can be sure that it is laminated glass. If it were tempered glass, the damage would have caused a catastrophic failure (a pile of millions of tiny pieces of glass where the window used to be).
