Secondary Glazing Installation

Professional, reliable and experienced installation team

We offer a comprehensive range of well-designed and reasonably priced windows which are cleverly designed for ease of fitting – as standard the windows include an aluminium frame combined with an integral timber frame to make it easy to fit to your existing window frame whatever the circumstances.


What are the installation costs?

Fitting secondary glazing in your home should be seen as an investment, an investment that brings multiple benefits including savings on household bills, thermal insulation benefits, noise reduction and more. It is also the ideal solution for retaining the character of the building, especially if the building is listed where the value needs to be retained.
