Effective glazing ideal for homes and businesses

Ensuring your existing windows remain untouched and unobstructed, secondary glazing features the installation of a discreet, slimline aluminium frame onto either the window reveal or the inside face of your existing window. This allows for improvements in thermal efficiency and security, without compromising the look and feel of your property.


Radiance Doors aims to become your first choice of installers in the Bury area. We have built up an enviable reputation for quality, and are ready to take on any project, big or small. We source products from Granada Secondary Glazing: a highly regarded manufacturer of secondary glazing.

The perfect choice for heritage buildings

If you own a listed or heritage property, or are within a conservation area, secondary glazing is the ideal choice. It allows you to improve the thermal efficiency of your home or workplace (by up to 65%), all whilst adhering to planning regulations and limitations.

Thanks to Granada Secondary Glazing's fantastic range we can install fixed, hinged, lift out and bespoke or arched windows. We can also supply units with a horizontal or vertical slider.


Secondary glazing is suitable for roadside properties, and can help reduce how much noise enters your home by as much as 80%.

Minimise condensation in your property

For condensation that forms on windows, an effective solution is to install secondary glazing. Our secondary glazing collection allows for low-level ventilation within the window reveal cavities, which in turn prevents the inner glass from becoming too cold. Ultimately, this prevents condensation from forming.


The unique trickle ventilation system that is installed into all our secondary glazing windows provides a simple, effective method of allowing background ventilation to enter your home and to control condensation levels.

Very pleased with the result

I got a good impression from Richard when he came over to look at the doors and I'm very pleased with the result. Excellent new doors, the installation guys cleaned up perfectly, could not be happier.
