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.
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.
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.
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 shockwaves. Lighter, thinner bullet resistant glass can be produced by the use of polycarbonate in the lamination.
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.
“Securing the contents of a building is critical; be it physical high value objects, highly sensitive data or the people inside.”
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.
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.
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; to the Main Hall window openings being 3.6m high and 2.0m wide.
Security was high on the agenda when plans were made for the restoration process of Tudor Hall, Newark, into a museum. Some of the historical artefacts including graffiti dates back to the early 1600s and are irreplaceable. Security measures taken need to be sympathetic to the building’s elegance and historical significance. Forty-five windows were treated using a range of Selectaglaze’s bespoke products, including units certified to Loss Prevention standard LPS 1175 level SR3 and PAS24, all accredited to Secured by Design.
Founded in 1966, Royal Warrant holder Selectaglaze has gained a reputation as a leading secondary glazing specialist offering high performance noise insulation, improved building energy performance, environmental control and certified security. Products are fully tested and assessed for performance and twice-yearly quality audits are conducted through the company’s ISO 9001 accreditation and LPCB.
