How it Works



Similar to car windshields and aircraft windows, KeepSafe is made by permanently bonding a thick polyvinyl butyral (PVB) plastic interlayer (Saflex) between two panes of glass under intense heat and pressure. Once sealed, the glass "sandwich" works as a single unit and appears transparent, just like ordinary glass. The result is windows and door systems with a durable, scratch resistant, and high-performance security protection.
