Acoustic insulation secondary glazing - noise reduction for Listed buildings and new builds
Selectaglaze Ltd
Most traditional single glazed windows, in Listed buildings, with poorly sealed frames offer little defence against noise. New developments on brownfield sites with new double glazing, strain against the high sound levels.
A single glazed primary window generally provide 20dB to 30dB reduction, which when you take the following figures into account, is not a very good barrier to everyday noise pollution. An acceptable sound pressure level for a bedroom is 30/35dBA and 45/ 50dBA for a classroom and traffic on busy roads reaches 70-80dBA. Well sealed secondary glazing with a cavity of at least 100mm from the primary window, can reduce noise in excess of 45dB. Combine secondary glazing with double glazed windows and a 56dB reduction is achievable.

Security and safety secondary glazing protecting environments and providing duty of care
Selectaglaze Ltd
Windows are often soft targets for intruders. If subjected to a bomb blast, flying shards of glass will be an extreme hazard. Secondary glazing provides an extra protective barrier; ideal for Listed buildings.
Some systems also aid containment;such as laboratories and secure health facilities, or offer protection against fire arms or spread of fire. Units have been tested and are accredited to a number of bodies: SBD PAS24:2016, LPS1175 SR1 SR3, ISO 16933 EXV19 EXV45, EN1522/1523 and BSEN 1363-1, 1364-1.
Units are suitable for museums Government Indemnity Scheme, critical national infrastructure, laboratories subject to HSE standards and buildings deemed vulnerable/high risk.
The result is safer, more secure environments at home,places of work or public buildings.

Thermal enhancing secondary glazing - energy saving for Listed buildings
Selectaglaze Ltd
An independent secondary glazed window, correctly installed and well-sealed on the inside of the primary widow, will significantly minimise air leakage. It traps an insulating layer of air that can reduce heat loss by up to 50% using standard glass and 65% with low-E glass.
U-values of 2.6 can be reached with standard secondary glazing, however if low-E glass is used they can further reduced to 1.8 and even further if enhanced thermal sealed units are used.
If you are a landlord; residential or commercial, and have Listed or heritage buildings in your estate, thermal enhancing secondary glazing can help improve EPC ratings and meet MEES regulations. In addition it will also help to reduce energy consumption and bills.
