Today's windshields are designed to help protect you in the case of an accident. They help keep passengers in the vehicle upon impact and keep the roof intact.
The windshield is an important component of the airbag deployment system.
Your windshield is classified as a "safety device" because it provides structural strength to your vehicle and helps to keep passengers inside the car if an accident should occur. It supports the inflation and performance of passenger side airbags. The passenger side airbag deploys upward and off the windshield at speeds up to 200 mph. Federal Motor Vehicle Safety Standards require adhesives to be nearly six times stronger for cars with passenger side airbags.
Your windshield is one of your vehicle's most important safety features. In fact, doing a safe, certified replacement requires some pretty exacting procedures. Not only does the new adhesive have to be heated to 180°, the old adhesive has to be meticulously pared down to 1/16th of an inch and the glass has to fit perfectly into the pinchweld (the metal frame on the vehicle).
SDAT is the amount of time required for your car to remain out of service until the new auto glass part can properly operate as a safety device. Cars with passenger side airbags require either more time or a faster acting auto glass adhesive to reach Safe Drive Away Time because of the additional strength necessary to support the deployment of the passenger side airbag. Federal Motor Vehicle Safety Standards require adhesives to be nearly six times stronger for cars with passenger side airbags.
A windshield is made of safety glass - - two layers of glass sandwiched around a layer of plastic. Separating these layers makes recycling a challenge, so most broken windshields that other auto glass companies replace end up in landfills. That adds up to about 600 million pounds of auto glass a year!
