Secondary glazing offers the advantages of contemporary glazing solutions, such as heightened energy efficiency and draft prevention, all without compromising the integrity of your original external windows.

Secondary glazing presents an optimal solution when you are unable to replace your existing windows.

Secondary glazing is an additional layer of glazing installed on the inside of your existing windows. It is a cost-effective and efficient way to improve the insulation and soundproofing of your home or office. Secondary glazing is ideal for listed buildings where the windows are historic and can not be replaced.

Secondary glazing offers a range of benefits

The installation of secondary glazing in your home offers a multitude of benefits. It’s important to note that this service is different from replacement double glazed windows, as it entails fitting an additional window internally, in front of the existing external sash or casement window. This approach is particularly advantageous if you live in a listed building, are constrained by planning regulations, or wish to maintain the authenticity of your historic property.

Here are some benefits of secondary glazing:

Thermal icon1. Improved Energy Efficiency

Secondary glazing can significantly improve the energy efficiency of your home or office by reducing heat loss through the windows. The additional layer of glazing creates a barrier that traps heat, preventing it from escaping. This means you can save on your heating bills and reduce your carbon footprint.

Soundproofing icon2. Enhanced Soundproofing

Secondary glazing also provides excellent soundproofing benefits. The additional layer of glazing acts as a sound barrier, reducing noise pollution from outside. This is particularly beneficial in urban areas where traffic noise and other external sounds can be a nuisance.
