Aluminum windows vary widely in quality and construction.  With a proper coating and a heavy duty design, aluminum windows can be useful in high wind applications such as high rises and in coastal areas, and on certain projects.  Aluminum windows are often limited to a couple of colors but offer a strong and weather resistant product at a fair price if you use a good product.  PGT builds aluminum windows in Florida that meet local and national building codes and are proven to work in our environment.
