Energy Absorbing Systems
Cable Catch, Tilt & Turn Windows, Doors, Curtainwalls
When protecting an opening against high blast levels, the window (or door) is equipped with a thin cable stretched between the jambs. The glass “balloons” in and stretches the cable that activates the energy-absorbing devices located at its ends.This is WindowGard's Defender’s Energy-Absorbing “cable catch” system. WindowGard Defender can incorporate blast protection in new and existing construction as well as in landmark and historic buildings.
