Mechanical Anchoring Systems....
Plain The mechanical anchoring system has been rigorously tested to the
ISC/GSA Blast Security Criteria using various types of glass and window
units. In this system the Fragment Retention Film (FRF) is applied to the
glass and wrapped onto the exiting window frame. The film is anchored there with
an aggressive transfer adhesive. The base-plate is bolted to the window
frame, mechanically securing the film and glass in place.
A cosmetic
cap (anodized or painted to match the frame) is installed to cover the
screws, base-plate and film, and a vinyl gasket is added to provide a
clean sharp appearance. The finished installation becomes part of the
window system and is virtually invisible to building occupants.

Adhesive Attachment
With the structural adhesive system the gaskets on the existing window unit
are removed or cut to allow adhesive to extrude into the frames' rebate. The
FRF is applied to the glass and allowed to dry. Next, a black architectural
structural hardening adhesive is applied over the film, over the existing
frame, and into the frame rebate.

Daylight Application
The Often fragment retention widow film is applied directly to glass to
reduce fragmentation hazards, but it also can be anchored to existing window
frames to increase the overall performance of the glass.
Every installation configuration is specific to the requirements of
the site.
