High quality double glazing can reduce noise levels by approximately 35 dB, and triple glazing often achieves similar results. While good quality triple glazing can offer enhanced acoustic insulation, it really depends on the products, materials used and the installation. Windows manufactured with acoustic glazing often feature thicker glass, laminated layers and a wider gap between each pane.
The Window Energy Ratings (WER) is a scale developed by the British Fenestration Ratings Council (BFRC) to measure the thermal performance of windows. The BFRC label indicates the rating of the window on a scale running from A+ (the most energy efficient) to G (the least efficient). The term 'glazing' refers to the glass component of building's façade or internal surfaces.
While both options improve efficiency, triple glazing cost has its potential drawbacks, such as added weight and reduced light transmission, which can be a concern for period homes. Vacuum glazing cost may be higher upfront, but for many, the aesthetic and performance benefits outweigh the disadvantages of triple glazing in sensitive restoration projects. However, it’s important to weigh up the disadvantages of triple glazing, such as the added weight and higher triple glazing cost, particularly when comparing it to more modern alternatives like vacuum glazing. While vacuum glazing cost can also be a consideration, it offers better performance in a slimmer profile, making it ideal for heritage or listed properties.

At the same time, it allows optimum amounts of sunlight to pass through the window. Our Advance glass boasts a neutral appearance and a centre pane U value of 1.1W/2mK. Whilst a G value of 50% still allows for maximum solar heat gain into the property through the glass. Advance comparable thermal benefits to triple glazed sealed units but is much lighter meaning less strain on hinges and moving mechanisms and is a much more cost effective solution also. Secondary glazing enhances thermal insulation, reducing heat loss by up to 70% and improving energy efficiency The amount of heat saved depends on factors like the quality of installation and the type of material used.
