Mechanical Anchorage Systems

Mechanical Anchorage Systems are available in a range of types and applications. There will be one which is specifically suited to your needs.

Cord Restraint Systems

These Mechanical Anchorage Systems comprise flexible shock absorbing cords, designed to arrest the inward travel of laminated or filmed glass. They are comparatively inexpensive and relatively easy to install. They work very effectively in conjunction with a daylight blast mitigation window film installation. Cord restraint systems are often ideal for retro fitting buildings which may not be considered targets, but are in close proximity to targets. Restraint systems may not be acceptable where visual aesthetics are important.

Catch Bar Restraint Systems

There are two primary differences between a catch bar restraint system and a cord restraint system. (1) It is a substantial piece of chanelled metal used to catch the glass (2) It is very rigid and utilizes the structure of the window frame and the building to maintain it’s strength. Therefore, the structure surrounding the windows must be evaluated for their ability to withstand the forces that the catch bar restraint system will transfer during an incident. Another obvious consideration is that the catch bar restraint system may obscure the view from the window. It is important to take these factors into account before specifying these particular Mechanical Anchorage Systems.

Gull Wing Restraint Systems

The gull wing restraint system is designed to hold the filmed broken glass in the window frame when the incident occurs. These Mechanical Anchorage Systems comprise an extruded plastic profile forming an angle with one face bonded to the blast mitigation window film on the glass and the other face bonded to the window frame. If the window breaks the gull wing restraint system will either hold it in place or hinder it from flying into the building.

Clamping Restraint Systems

The clamping restraint systems are engineered to be highly reliable and repeatable. Blast mitigation window film is applied to the inside of the glass with an overlap of 2 inches on every side of the window that is to fitted with the clamping restraint system, which is then fitted around the frame over the tail of the blast mitigation window film. The clamping restraint system is fixed to the film using high adhesive double back tape. It is then screwed into place through the base profile in the window frame. Its grip surface clamps the edges of the blast mitigation window film. These types of Mechanical Anchorage Systems can be applied to 1, 2 or 4 sides of the window frame, depending on the level of protection required. It may also be screwed into the window frame in a variety of ways to optimise the buffering and shock absorbing element of the system.
