Enhanced Protective Glass (EPG) is a glass product for all-around window protection. Made by laminating a sheet of polyvinyl butyral (PVB) between two sheets of glass under heat and pressure, EPG offers four benefits for your vehicles and officers. 1. EPG safeguards vehicle contents by protecting from intrusion. EPG provides more than ten times the intrusion resistance of standard tempered glass. 2. When impacted, the glass adheres to the PVB interlayer. This means officers can replace or repair the window after their shift, keeping them on the street protecting the community. 3. EPG can reduce wind and traffic noise by up to 6 decibels compared to standard tempered glass. This noticeable improvement allows the driver and passengers to communicate more easily. 4. With its protective PVB interlayer, EPG blocks out up to 95 percent of the sun's harmful UV rays. This helps protect the vehicle's interior and equipment from fading and deterioration.
