Secondary Glazing - Primary Windows - Acoustic Glass - Secondary Windows

Selectaglaze - Lounge

If you are looking to improve the thermal, acoustic or security performance of existing primary windows in a Listed property or one in a conservation area, then secondary glazing is often the only answer. However; with more and more developments on brownfield sites, we are seeing a rise in the use of secondary glazing to support the primary windows, to help achieve the acoustic requirements, in these extremely noisy areas.

Selectaglaze secondary glazing is an independent window fitted to the room side of an existing opening and used to control the internal environment of a building. Often primary windows cannot be replaced due to budgetary, lease or planning constraints, therefore secondary glazing offers a bespoke and cost effective solution. Units can be neatly incorporated into a building fairly quickly and unobtrusively, so it doesn't disrupt normal operations. It is also a reversible intervention that can be neatly incorporated into a building quickly and very unobtrusively; perfect for Listed buildings and new builds.

A sound reduction of 45dB is readily attainable with secondary glazing and substantiated with acoustic reports. Outstanding performances of up to 55dB are possible, when specialist acoustic glass is used.

Secondary glazing limits heat loss by almost 50% as it traps an insulating layer between the primary and secondary windows. Using specialist thermal units and glass such as Spacia or the Selectaglaze enhanced thermal casements, very low U-values can be attained which are important when trying to gain and meet high levels of BREEAM ratings and Passivhaus/EnerPHit standards.

Selectaglaze will showcase a range of its products between the 7th and 9th March 2017 at Ecobuild, ExCel London. Selectaglaze will exhibit on both days at Stand C174. To view upcoming events Selectaglaze will be attending please click here.
