Which is the best windshield for replacement? What is the difference between OEM and aftermarket glass?

I'm trying to replace a broken windshield on my car. And I got quotes from $95 to $190. Some gives Life-time warranty on glass, others on labour.. Some say they use OEM glass others say they use aftermarket glass. Are aftermarket glass bad? How do you distinguish between OEM and aftermarket glass? And what's the catch in the huge price difference?Which is the best windshield for replacement? What is the difference between OEM and aftermarket glass?
On a new car, every part comes from the original equipment manufacturer (the OEM), including the windshield. For windshield replacement, you have the option to select a replacement made by a company that manufactures OEM windshields, such as PPG, or glass made from non-OEM manufacturers (';aftermarket glass';). Both OEM and aftermarket glass must comply with the Federal Motor Vehicle Safety Standards, but ?there are two important OEM benefits:

An OEM replacement windshield is produced from original equipment-style tooling. This type of windshield will have the appearance of your car's original windshield and will fit properly in the window frame making noise and leakage problems much less likely.





OEM glass manufacturers partner with automobile producers to enhance overall functionality and improved performance. Because of their close work with carmakers, OEM manufacturers have a greater knowledge of the engineering demands a car can place on the windshield and their replacement windshields are made using the same quality assurance systems as for new vehicles.

Safety glass is used in all automobile glass. It is manufactured to reduce the likelihood of injury, if it breaks. There are two different types: laminated glass and tempered glass.



Windshields are made from a lamination process. A windshield actually consists of two pieces of glass, bonded together by a vinyl inter-layer. This vinyl layer cushions your head during impact. If a windshield breaks during impact, the broken pieces will generally adhere to the plastic lining.



Side and rear windows consist of tempered glass, which is produced by heating the glass to more than 1,100掳F and then rapidly cooling it. This results in the outside surfaces of the glass becoming harder than the center of glass and, therefore, is stronger than regular glass of the same thickness. If broken, tempered glass will break-up into very small pieces.
