Royal Warrant Holder Selectaglaze has been designing secondary glazing systems since 1966 and has been working on a framework agreement with Crossrail and Network Rail since 2011.
Rail projects and station upgrades cause noise from construction works and the company’s bespoke secondary glazing is providing insulation to affected buildings. Major rail stations are also part of critical national infrastructure (CNI) and security is a consideration. Windows in critical locations need to be protected against forced entry and the effects of blast.
Selectaglaze has developed and tested a range of security frames suitable for retrofitting. These have resisted physical attack up to level 3 of Loss Prevention Standard LPS1175 and blast to level EXV15 of standard ISO16933 (100Kg of TNT equivalent at a distance of 15M). The units are available in a range of styles including horizontal sliding, balanced vertical sliding, hinged and fixed. The preferred frame material is aluminium, a metal that can be extruded into the complex section designs needed to meet the performance demands.
Many station buildings are listed or have architectural merit and the windows need to be retained. Purpose designed secondary glazing can be sympathetic to the character of a building and as a reversible adaptation will generally receive listed building consent, the company adds.
The secondary windows are purpose made to precisely fit each window opening. Full off-site fabrication allows installation to be completed with minimal disruption to buildings in occupation, and the use of lean processing methods and flexible programming will support the very tight programmes that clients often need, according to the company.
