Abstract

The present invention provides a mechanical attachment system for attaching window film to the window frame, such as a batten, profile clamp or other structural device (referred to generally throughout the application as “attachment device”), which attachment device absorbs energy instead of simply transferring energy to the window frames (as is done in traditional devices). The absorption of energy is accomplished by incorporation of a flex area in the attachment device. The flex area bends or flexes when acted upon by blast loads and effectively eliminates the tearing effect (of the film) that all conventional mechanical attachment systems exhibit.
