Frequently Asked Questions


What are various windows made of and what will work best for me?
Basically there are three types of materials used. Aluminum windows, more frequently used in commercial applications due to their superior strength, conduct both heat and cold, so they're very poor insulators. Wood windows, which require constant painting and caulking, can absorb moisture, making them difficult to open and close. Using a superior hardwood or using aluminum cladding will minimize the problem. Solid vinyl windows, however, never need painting and won't show scratches, because the color goes throughout the material. This is why vinyl windows are quickly becoming the most popular choice for both new construction and replacement applications.

In addition, you should certainly consider custom-sized windows for the very simple reason that they'll fit better. Stock-sized windows require extensive carpentry work both inside and outside your house. That can be very costly and inconvenient. Alside custom-sized windows, on the other hand, are manufactured to fit your existing window opening. You get the style and options you want while maintaining your glass area.

Is there any difference in how Vinyl windows are made?
There are two basic types of construction: Mechanically fastened windows are screwed together at the corners. And welded windows, becoming more and more popular, that use a chemical or heat process for joining. Alside produces mechanically fastened and welded windows. Our mechanically fastened windows feature a unique overlap corner design for extra strength, while our welded versions utilize state-of-the-art heat welding equipment. Beware of windows with mitered corners screwed together or chemically welded corners, as they probably won't perform as well for you.

Can I replace my old windows with different styles or types?
Certainly, since all replacement windows are custom made, you can literally please yourself. Our design professionals are only too pleased to help in the design process.

Aren't all window manufacturers essentially the same?
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 China and other foreign countries. We're proud to say that every window and door we sell is manufactured right here in the U.S.A.

Do Vinyl windows require a lot of maintenance?
Because frames and sashes are made of vinyl, you can say goodbye to painting and caulking. Vinyl windows won't stick, and you don't have to remove storm windows in order to clean them. In fact, you can do it all from inside your home. An occasional wipe with a damp cloth will keep your windows looking like new for years to come.

I have been reading about different test results on windows. How should this impact my buying decisions?
Be careful when looking at extremely specific results since many of them do not really indicate how well the window will work for you. Some apply to just certain parts of the window, like the glass and its R-value, and do not give an overall picture. Tested in nationally-certified labs windows are engineered to provide the optimum in energy savings and are monitored by the National Fenestration Rating Council.

What is more important in saving energy, the frame or the glass?
Since 80% of a window is glass, real heating and cooling savings come from what is known as "improved glass performance," not a high R-value on the frame. Our Vinyl manufacturers use the latest technology, known as a high performance warm edge spacer system. This spacer system helps to improve the performance and the longevity of the insulated glass unit, and is standard on all High Performance Low E windows.

What is the ENERGY STAR® Program?
The ENERGY STAR® progam was created by the Environmental Protection Agency and the U.S. Department of Energy to help consumers in the recognition of energy-efficient products.
