Hearing about break-ins or threats of terrorism has become a regular occurrence, which can be unsettling. Selectaglaze secondary glazing can provide an unseen level of security to any property. It creates a second barrier of protection from the inside that can prevent the most determined thief or protect the occupants from the effects of bomb blast.
Securing the contents of a building is critical; be it physical high value objects, highly sensitive data or the people inside. If this is the case, secondary glazing could provide the solution.
Physical attack - Under physical attack secondary glazing works by providing a second barrier to entry. At lower risk levels it must prevent manipulation of the locks and catches or removal of the glass or glazed panels. As the performance increases it must resist levering or use of cutting tools including penetration of the glazing, which at higher risk levels will be a sophisticated combination of glass, resin and polycarbonate.
Blast mitigation - Secondary glazing can protect occupants and contents from the effects of an explosion by containing the flying shards of glass from the breakup of the primary window under the blast load. Fixings, frame, locks and glass are all designed to absorb the blast wave.
Ballistic - Protection from firearm attack is achieved by several layers of glass of various thicknesses laminated together. The front layers of glass are designed to shatter, thereby absorbing the initial impact energy, the subsequent glass and interlayers absorb the lower level shock waves.
Fire - Fire resistant glazing provides a protected escape route for occupants. Specialist glass and intumescent seals set within appropriate framing, resists the intense heat of a fire.
Banqueting House, London was treated with Selectaglaze blast units to provide ample levels of security to protect the Rubens ceiling painting, historic architectural features and those who visit/use the Royal Palace. The design replaced the blast net curtains as well as providing a significant level of noise insulation. Testing was carried out for what turned out to be the largest ever single casement to be blast tested in the UK, as the Main Hall window openings are 3.6m high and 2.0m wide.
