Laminated glass now being used in side and rear windows

Detroit, Michigan – More than 40 production vehicles on display at the 2007 North American International Auto Show in Detroit use laminated glass in their side and rear windows, as well as roof applications, reports the Enhanced Protective Glass Automotive Association (EPGAA). Laminated glass appears on 36 vehicle platforms in North America today, compared to only three platforms worldwide five years ago.

The glass, which consists of a tough plastic interlayer between two glass panes, provides improved interior acoustics, safety, security and ultraviolet protection. The EPGAA says that it can protect a vehicle from entry by thieves for about 30 seconds, as opposed to one-tenth of a second for tempered glass; it could help save up to 1,300 lives annually and reduce occupant ejection in collisions; it reduces interior noise by three to four decibels; it screens up to 98 per cent of ultraviolet (UV) rays, associated with skin cancer, compared to 66 per cent by tempered glass; and vehicles with laminated glass can be easily coated with infrared (IR) coatings, which can reduce the vehicle’s interior temperature by up to 7C compared with untreated tempered glass.

Laminated glass has been used in windshields for more than 70 years; laminated glass is now being developed specifically for use in side and rear window, and roof applications.
