There are millions of homes in the UK and whilst a large proportion can improve insulation levels by replacing windows this is not an allowable option for listed buildings or those in conservation areas.
Large numbers of traditional pre 1919 homes and many old commercial and industrial buildings that are converted to provide homes incorporate window designs that are an important part of the UK’s architectural heritage.
Secondary glazing is a reversible adaptation to a building and hence is an acceptable solution for listed buildings up to grade 1 and for the large number of building owners that wish to retain original windows.
Selectaglaze secondary glazing is used extensively by large private estates and developers often working through architects or agents, social housing providers, private landlords, and homeowners.
The energy used to heat homes is responsible for about one fifth of UK CO2 emissions. The growing need to reduce emissions, conserve energy and manage rising energy costs will encourage improved insulation standards. Selectaglaze secondary glazing systems incorporate efficient seals to markedly reduce draughts and when glazed with low emissivity glass will reduce heat loss by up to 65%.
This will lower running costs and assist with carbon reduction objectives.
Cities and town centres are attractive places for homes but the 24 hour society can lead to untenable noise levels at night. Secondary glazing offers very effective noise insulation and will outperform normal double glazed windows. The additional secondary window is generally fitted 100-150mm away from the primary window and the wide air space limits noise transmission across the panes. In comparison the two panes of glass in normal double glazed units are set close together allowing the noise to pass through much more easily.
Selectaglaze secondary glazing systems fitted with standard glass are capable of reducing noise levels by 42 - 45dB and even higher levels if thicker glass is introduced.
Windows are normally seen as “soft targets” for intruders and a secondary window, particularly when fitted with a lock, provides a simple additional barrier to entry. Selectaglaze also offers enhanced systems accredited to “Secured by Design” and are a “Police Preferred Specification”. These windows undergo rigorous testing and the most secure range matches the resistance offered by heavy bars or grilles and avoids the home feeling like a fortress.
Selectaglaze secondary glazing is designed to have minimal visual impact on the character and design of the original building - both externally and internally. The custom made units are able to reflect the lines of the original windows, including arched, curved, round and curved on plan. The standard finish is white which matches most windows but a wide range of colours including wood grain effects is available to help the frames blend with the existing décor.
Listed Building Consent
Work on listed buildings has to be covered by a Listed Building Consent and when considering work in Conservation Areas advice should be obtained from the local Conservation Officer. In most instances, secondary glazing will be an acceptable addition.
Secondary glazing is suited to traditional homes, flats and mansion blocks or any home suffering from excessive noise. Selectaglaze can provide a comprehensive service but not throughout the UK. Products are available through Preferred Installers in some regions and details will be provided on request.
Private Estates and private landlords
Many private landlords wish to improve the sustainability of their estate and comfortable, well insulated properties can be more attractive in the lettings market. Selectaglaze will work to develop a clear understanding of the needs of the Estate to ensure continuity of treatment and a responsive service.
Many traditional commercial buildings suitable for conversion to homes are in noisy city centres, an attractive location for living and working, but dealing with excessive noise levels can be a critical factor for a successful development. Selectaglaze will work with acousticians and architects to identify the most effective solutions.
Social Housing stock includes traditional buildings some of which are listed. In these homes secondary glazing will meet the requirements of The Decent Homes Standard to improve insulation levels. Also many inner city properties will suffer from excessive noise or have security problems that must be addressed by the ‘Secured by Design’ initiative. Selectaglaze will work with maintenance teams, surveyors and other interested parties to design solutions that will work for the provider and the tenant.
