DETROIT, MI – Vehicle glazing has evolved from its original task of keeping bugs out of our teeth to the multi-functionality of Enhanced Technology Glass (ETG). ETG glazing solution is manufactured through a collaboration between PPG Industries and Saflex, a unit of Solutia Inc., and will be featured on General Motors 2008 full-size passenger vans.

The use of ETG by GM in its full-size passenger vans marks the first-ever use of this glazing technology in a vehicle, the manufacturer said. ETG is an advanced glazing system that is an evolution of Safe and Sound laminated glass from PPG, a product currently in use on other GM vehicles for reducing cabin noise.

Instead of using standard polyvinyl butyral (PVB), ETG incorporates the Saflex K series high security interlayer — a tough and resilient composite PVB structure especially designed for penetration resistance —– which is laminated under heat and pressure between two sheets of PPG’s glass. This creates a glazing system that is stronger and more resistant to tearing and penetration than standard laminated glazing.
