How the window material affects the average cost of double glazing
Apart from the style of a window, the material for the frame used also impacts on the average cost of double glazing:
Unplasticised Poly Vinyl Chloride, otherwise known as uPVC, has been one of the most popular choices for double glazed windows in the UK since the eighties.
uPVC double glazing is thermally efficient, low maintenance and secure. It's also the most economical material for windows.
The average cost of double glazing for uPVC casement windows is between £600 to 1,800 depending on size, glazing design and how many are being replaced in the property.

Another easy to maintain window frame choice that's popular for it's slimline appearance.
Aluminium isn't as thermally efficient as uPVC but does offer a contemporary look and most often used in modern properties.
The cost of double glazed aluminium windows is 25% more than uPVC but 25% less than timber frames.
Nothing beats the look of well-maintained wooden window frames. A quality hardwood window is a good investment for a home and can add significant value, especially in period properties.
The oldest material choice of windows, timber frames can last for years if they are well looked after, but they are high maintenance and need a lot of attention.
The average cost of wooden double glazing windows is 25% more than aluminium and 50% more than uPVC.
