Beware of windows with mitered corners screwed together or chemically welded corners, as they probably won't perform as well for you. Certainly, since all Alside replacement windows are part of Alside's Window System. You may want to consult an independent design specialist to find the type of window that best complements your home's natural design. No matter what style or combination of styles you choose, however, Alside can custom-manufacture it all for you. Not at all.
Many companies buy their parts and glass from various outside sources.
You should also know that although a lot of manufacturers claim their windows are American-made, many in fact may be imported from Canada and other foreign countries. We're proud to say that every Alside window is manufactured right here in the U.S.A. 5. You should look for a window that offers both superior strength and energy efficiency.
