2-Minute Tech: Hot Rod and Custom Glass Tip

Laminated Windshield Glass Tip

You have finally made it to the point of needing glass for your hot rod or custom car or truck project.

So, what do you need to know?

There is a difference between glass for the windshield and for side or rear windows:

  • Windshields use “Laminated Safety Glass”. This means there is an inner and outer piece of glass laminated to a .030″ thick plastic liner. This glass stays in place when it breaks. It is designated “AS-1”.
  • Side and Rear Glass is traditionally made of “tempered glass”. This glass is very hard and doesn’t break easily, but when it does, it shatters into a thousand pieces. It is designated “AS-2”. The NSRA and other street rod organizations recommend that you use only “AS-1” in windshields — Never use “AS-2” for your windshield.
  • Laminated Safety Glass ~ A finished windshield consists of two glass layers sandwiched around a plastic interlayer:
