Aluminium-clad windows are becoming more popular for business and homeowners. They are becoming more popular due to the fact that they are ideal cladding for harsh environments because they can't be dinged or dented. They are also low-maintenance once installed, while remaining aesthetically pleasing. There are, however, several disadvantages to using aluminium-clad windows.


One of the primary disadvantages of aluminium-clad windows deals with colour. Although they come in a wide variety of colours, you can not paint them. More painting or staining is required because of the new exterior and interior trim. Repainting is not recommended since it is extruded, it not as easy to shape. Vinyl looks slightly bulkier compared to metal and wood. Therefore, you may have a difficult time trying to match the exterior colour of your home with your aluminium-clad windows.


Aluminium-clad window prices start at about £162 per window, as of 2010, but adding impact-resistant and laminated glass drives costs way up. Aluminium is also a poor insulator so many aluminium window manufacturers offer higher nickel content to the aluminium, which makes them more expensive. In addition, extra sealants are required to improve thermal resistance and reduce condensation.

Energy Inefficient

Aluminium is not consider an efficient insulator. The aluminium-clad window will transfer the temperature, and in the winter months, may feel cold to the touch. Because aluminium-clad windows are thinner than wood or vinyl windows, the glass is also thinner. This makes them easier to break and less insulating. Due to the lack of efficiency, there is no tax credit offered on aluminium clad windows.
