The Costs of Double Glazing

Double Glazed Windows in EnglandDouble glazing is often necessary to keep the temperature in the home comfortable and to keep out the noise. Many homes in Birmingham are old and only have single-glazed windows. To get the benefits of double glazing, you should replace all your existing single-glazed windows. However, it can get quite expensive. 

The money you spend depends on several things. Aside from the number and size of the windows, you also have to consider the material and design. Here are some costs to expect based on the number of openings.

Single opener casement

This type of window is usually the most affordable, according to Finesse Windows. You only have to deal with a simple window, seal, and hinge. A 600 x 900 mm window using uPVC costs about £200 and more. A 1200 x 1200 mm one will cost £300 and up. If you want to let more light in, you can go for a rectangular 940 x 1600 mm window, which starts from £450. A typical three bedroom house with 12 windows costs £4,500 and up for the materials and installation.


You can expect to pay quite a bit more for this type. One 600 x 900 mm sash window using uPVC will cost you up from £500, while a 1200 x 1200 mm one will cost £600 or more. You can also choose wood instead. Double-glazing a three-bedroom house with 12 windows starts from £10,000 for materials and installation.

Tilt and turn

If you want to go fancy, you can choose tilt and turn windows using wood. A 2-light 1200 mm tilt and turn window will cost you £800 or more. If you use uPVC, the price for a 2400 x 1200 mm drops to £500. A standard 1600 x 900 mm tilt and turn window made of uPVC is the most affordable at £240 and up. These average prices are only for the materials and do not include installation.
