Secondary Glazing Offers a Number of Sustainable Benefits


A discreet way to enhance the soundproofing and condensation control for your windows is by using an installation known as secondary glazing. This cost-efficient solution provides a dependable way to minimise noise and reduce energy costs in urban areas. The method is regularly used for structures in conservation areas as well as in listed buildings.

A Reversible Alteration

Secondary glazing involves the use of a lightweight aluminium material, thereby making it a subtle yet notable window upgrade. This type of renovation is considered to be a reversible alteration and is supported by the Listed Property Owners Club and English Heritage. The frames used for the installation are not only unobtrusive but they need little maintenance or care. You can either install a face-fixed update which fixes to an existing window, or a reveal-fixed improvement which entails fixing the glazing into the window reveal.

How Secondary and Double Glazing Differ

Sometimes secondary glazing is confused with double glazing. Double glazing is different than secondary glazing as it works by capturing air between two glass panes. The trapped air, in turn, creates an insulation barrier that serves three functions: it prevents heat loss or gain, reduces noise, and lowers condensation.

When Secondary Glazing Is Used

On the other hand, secondary glazing for listed buildings entails adding a slim-line window to an existing window and frame. By fitting the glazing, you can save about ten percent on your energy costs. According to the Energy Saving Trust, secondary glazing is an “ideal solution” if you are an individual or business that cannot replace the windows in your structure with a double glazing process.

The Benefits of Secondary Glazing

The advantages of secondary glazing cannot be overlooked. Not only does the installation minimise drafts and reduce noise but it also provides an extra security barrier. Condensation control, as noted, is strong and the environmentally-friendly option reduces the carbon footprint.

Windows Are Made to Measure

All aluminium frames that are used for double glazing are painted a standard white. However, you can also choose from a variety of RAL colour alternatives. In fact, you can select from over 200 hues. The windows used for secondary glazing are made to measure with choices that accommodate most window styles.

Bespoke Window Styles

Among the choices, horizontal sliders are the most popular selection. However, as noted, secondary glazing providers can also install other styles such as vertical sliders, fixed windows, hinged units, and lift-out windows. The installation can also be configured to form arched-type units.

The Best Soundproofing Choice

If soundproofing is needed, then experts suggest employing a different thickness of glass in the glazing process than what is used in your current windows. For example, acoustic glass supplies the optimum in noise reduction.

Keep Heat from Escaping with Thermal-Coated Glass

Also, for maximum performance thermally, specialists suggest using low E glass which features a heat-reflecting coating that keeps heat within a room. Talk to a secondary glazing specialist today to make sure you choose a renovation that is best suited for your property.

If you own a structure that is a listed building, then don’t hesitate to make an affordable upgrade such as secondary glazing. This latest innovation ensures both the historical value and sustainability for a commercial or residential building in the UK.
