Project Detail

Commercial Window Shield was chosen to install fragment retention film on all the windows at the Department of Energy headquarters building in Washington. The James Forrestal Building, as the structure is known, is one of the most well-known buildings in the nation’s capitol. Assigning the project to Commercial Window Shield was made easy because the company has a GSA contract number.

The project involved applying security film to the inside surface of nearly 4,000 panes of glass. Most of the work was done by attaching the film to the window frame using Commercial Window Shield’s Blastight Film Attachment System. Some areas were not suited to the mechanical attachment, so the company used its wet-glazed system, which involves using Dow’s 995 structural silicone. Both of applications met GSA’s strict requirement for level C buildings.
