Selectaglaze secondary glazing systems using low emissivity glass can reduce heat loss by more than half and achieve a U-value of around 1.9. With sealed unit glazing this is further reduced, and a figure as low as 0.8 can be achieved.
Bespoke manufacture and high-performance seals ensure the tightest fit, reducing air infiltration and almost eliminating drafts.
Selectaglaze glazing has been used to help achieve BREEAM ratings on various projects, Wiltshire Town Hall and Ham Yard Hotel have achieved a BREEAM excellent rating, and Albany House and Mortimer Street apartments have received a BREEAM “Very Good”. In addition a recent project saw a Georgian Townhouse retrofit with secondary glazing which approaches Passivhaus EnerPHit standards.
