Security Security Secondary Glazing
It seems that nearly every day we hear stories of break-in’s and threats of terrorism. It is unnerving and affects all of us, as we could all be at risk. 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. You may be looking to find ways to secure the contents of your building; be it physical high value objects or highly sensitive data or the people within. 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 work in harmony deflecting and yielding to absorb the blast wave. PVB interlayers are used in the laminated glass composition to stretch and contain the blast.
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, subsequent glass and interlayers absorb the lower level shock waves. Lighter, thinner bullet resistant glass can be produced by the use of polycarbonate in the lamination.

FIRE
Fire resistant glazing provides a protected escape route for occupants. Specialist glass, together with fire and intumescent seals set within appropriate framing, resists the intense heat of a fire.
CLEAN ENVIRONMENTS
Secondary glazing with its high-performance seals and easy clean surfaces can provide an efficiently sealed envelope in clean, antibacterial and positive or negative pressured environments. Fitted on the inside of primary windows or in partitions, it can be used to stop the ingress of dust and grime and provide a protected space for blinds.
There are a number of buildings which require security secondary glazing, for a number of reasons and those that can be mentioned are:
Main Pic - A number of museums have been treated with Selectaglaze secondary glazing, from more basic levels of security like Secured By Design to enhanced security depending on the artefacts and collections contained within.
The Holburne Museum, Bath was treated with Selectaglaze SBD units to provide sufficient levels of security to protect the invaluable silverware, porcelain and china collections, in addition to the oil paintings and bronze statuettes.
Left Pic - Banqueting House, Whitehall, required secondary glazing to enhance the thermal properties of the building as well as provide high levels of security to protect the historic interior of the building.
Right Pic - Supreme Court, Parliament Square was treated with secondary glazing to gain the three benefits the products can provide. Thermal enhancements, noise reduction and enhanced security, due to the location and nature of the building.
