Secondary Glazing

Secondary Glazing

Secondary glazed windows are an effective and cost-efficient solution for enhancing the thermal insulation and acoustic performance of homes or buildings.

Secondary glazed windows are installed on the interior of the existing windows, creating a layer of air between the two, which is an effective barrier against noise, drafts, and heat loss.

One of the significant benefits of secondary glazed windows is their ability to reduce energy consumption and lower the carbon footprint. The insulation between the two windows creates a thermal barrier, reducing heat transfer and air leakage, resulting in lower energy bills. Additionally, secondary glazed windows can help to reduce noise pollution, making them an excellent option for properties located near busy roads or airports.

Overall, secondary glazed windows are a cost-effective way of improving the energy efficiency of buildings while delivering maximum performance regarding sound insulation, thermal performance, and security. They can also help to preserve the historical character of a property while providing superior insulation compared to traditional single-glazed windows.
