What is an aluminium bay window?

First, let’s see what an aluminium bay window is. An aluminium bay window is actually any window made of aluminium that comes out of the building’s wall, making different protruding shapes like square, curved, or even multiple storeys. This protruding shape lets more light come into your room and also gives an aesthetic style to your building.

The cost of bay windows is relatively high, because they are larger than other types of window styles like casement windows. Of course, the cost might vary according to the following factors:

• Number of windows: The size of your home and the number of windows you need affect the cost.
• The type of bay window: The type of bay windows and the number of panes can increase the cost. For example, aluminium sash bay windows have different prices from casement bay windows made of aluminium. Moreover, the cost of bay windows is different from bow windows.
• Glazing options: Triple glazed bay windows are more expensive than double glazed windows. However, triple glazing can reduce energy bills compared with double glazed bay windows.
• The company you choose: The cost of installation is considerable, and there is a difference between what large, nationwide companies offer and what local installers charge you.
• Frame material: If you choose other materials rather than aluminium, you might have to pay more.

Regarding the frame material, you’ll have two other common options rather than aluminium: uPVC and wood. In the UK, aluminium windows are really popular, especially aluminium bay windows. Although other bay window materials like uPVC bay windows and wooden bay windows have their advantages, aluminium is still the choice of many homeowners.

Overall, the aluminium bay windows cost is approximately between £1,550 and £2,340. The average price is around £1,945, and with the installation cost, you have to expect something between £2,050 and £3,740.

Why choose an aluminium bay window?

Now, let’s take a closer look at the pros and cons of aluminium bay windows to figure out why you have to choose this window style and this frame material.
