How to Choose Between Tempered and Laminated Glass

Add Article To List
Watch Your Temper!

You have finally gotten to the point of needing glass for your Hot Rod. Now 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.

Note: When having your glass cut, tell them to place the engraved information logo in one corner of the windshield that designates glass type.
