Keeping the heat in and the noise out, when refurbishing old and Listed properties can cause difficulty. With the pressing need to reduce the amount of energy used in buildings, secondary glazing can be a solution to a multitude of twenty first century problems.

Fitted to the room side of existing windows, Selectaglaze’s secondary glazing is sympathetically designed to meet the needs of the project. To combat draughty old inefficient windows, the installation of secondary glazing with low emissivity glass will achieve a U-value of 1.9.

With such high performing products, Selectaglaze secondary glazing has been used on a number of projects that have gone on to gain BREEAM ratings and a most recent refurbishment of a Georgian Townhouse is approaching Passivhaus EnerPHit standards, which is no mean feat.

Noise is also a major problem, whether it is containment or exclusion. Using Selectaglaze’s units, a sound level reduction of 45dB is possible, rising to more than 50dB when specialist acoustic glass is used. The results are achieved using high performance seals and an air gap between the windows of 100mm or more.

Another benefit of secondary glazing is enhanced levels of security. Selectaglaze’s range of security units have been fully tested and certified to provide protection against blast, physical and ballistic attack and 30 minute fire Integrity rating.

Where constraints from planning guidelines, lease conditions or budgets prevent the windows from being replaced secondary glazing will provide an attractive, practical and cost effective solution. It is also a reversible intervention and therefore highly appropriate for Listed and period buildings.

Established in 1966 and Royal Warrant holders since 2004, Selectaglaze is the leading specialist in secondary glazing.
