Mechanical Attachment System

This method is used for enhanced glass retention, anchoring 8 Mil or thicker safety film to the window frame with a metal batten system. The safety film is installed to the glass, overlapping the window frame by approximately 1 inch. A metal batten system is placed over the overlapped film and screwed into the existing window frame, securely attaching the window film to the frame. Depending on the type of glass retention needed, the mechanical system can be attached as a one-sided (top), two-sided or four-sided installation.
