Helping projects achieve BREEAM ratings

Wasted energy and the thermal efficiency of our buildings have become important topics on both an environmental and financial level.  Our buildings account for more than 40% of all carbon emissions, therefore the requirement to create ways to reduce our ‘footprints’ has become a major concern.

Selectaglaze secondary glazing systems using low emissivity glass, can reduce heat loss by more than half across the window and achieve a U-value of around 1.9. With sealed unit glazing this is further reduced, and a figure as low as 1.3 can be achieved.

When achieving airtightness is a requirement, secondary glazing can provide significant improvements when changing the original draughty windows is not possible. This is generally when a building is Listed or sits within a conservation area.  Air permeability performance below 5m3/h.m3 is readily achieved with Selectaglaze sliding systems and below 1m3/h.m3 with Selectaglaze hinged systems.

Secondary glazing is an independent window fitted to the room side of a building, and is a discreet and fully reversible adaptation, widely accepted by most Heritage bodies. All of Selectaglaze’s units are bespoke to the individual window and using high performance seals ensure the tightest fit, reducing air infiltration and virtually eradicating drafts.

Selectaglaze secondary glazing has been used on buildings across different sectors from Listed offices to new build hotels helping projects achieve high BREEAM ratings. Selectaglaze has worked on projects such as Wiltshire Town Hall and Ham Yard Hotel which have both achieved a BREEAM “Excellent” rating and Albany House and Mortimer Street apartments have received a BREEAM “Very Good”.

The Selectaglaze range is extensively tested and offers designs to suit all buildings across all sectors.
