  Aluminum-clad windows are becoming more popular for business and home owners. 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 aluminum-clad windows.
  
  

Color

• One of the primary disadvantages of aluminum-clad windows deals with color. Although they come in a wide variety of colors, 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 color of your home with your aluminum-clad windows.
  
  

Expense

• Aluminum-clad window prices start at about $250 per window, as of 2010, but adding impact-resistant and laminated glass drives costs way up. Aluminum is also a poor insulator so many aluminum window manufacturers offer higher nickel content to the aluminum, which makes them more expensive. In addition, extra sealants are required to improve thermal resistance and reduce condensation.
  
  

Energy Inefficient

• Aluminum is not consider an efficient insulator. The aluminum-clad window will transfer the temperature, and in the winter months, may feel cold to the touch. Because aluminum-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 aluminum clad windows.
