GullWing Anchoring System

An application of window film will provide your building with a valuable additional layer of valuable protection, but applying the film in conjunction with an attachment system such as GullWing will deliver the most comprehensive security possible.  

As an approved provider and installer, The Window Film Company is able to offer the GullWing Attachment System. This system uses a flexible membrane that is attached to both the filmed glass and the window frame, serving to hold them both in place in the event of an explosion or attempted security breach.

As an attachment system, with the sole aim of GullWing is to prevent the filmed glass from leaving the window frame, helping mitigate against injury or damage inside the building. It works by absorbing the additional energy that the glass is subjected to and redistributing it across the opening.

The system is installed after the installation of SafetyShield window film and the flexible membrane expands when the glass is acted on by an outside force, effectively absorbing a portion of the energy whilst ensuring that the glass and film remain within the frame. This system is available in three different sizes in order to accommodate different window frames, with the membrane available in either black or grey.
