Encapsulation is a molding process where a polymer trim is formed directly around the perimeter of the glass. This trim is shaped precisely to fit the vehicle body and is designed to support adhesive bonding, improve alignment, and streamline installation. 

Encapsulated sidelites offer more than just a clean finish. The molded edge can include built-in style features, attachment points, or even hinges for side windows in vehicles like minivans and wagons. This solution helps improve manufacturing efficiency, enables bolder vehicle designs, and contributes to a more refined appearance.
