Is there any difference in how windows are made?
	There are two basic types of construction for vinyl windows. Mechanically fastened windows are screwed together at the corners. Welded windows, becoming more and more popular, that use a chemical or heat process for joining. All of our window manufactures utilize a state of the art welding process called fusion welding which uses a heat joining process. Beware of windows with mitered corners screwed together or chemically welded corners, as they probably won't perform as well for you.
	I have been reading about different test results on windows. How should this impact my buying decision?
	Be careful when looking at extremely specific results since many of them do not indicate how well the window will work for you. Some apply to just certain parts of the window, like the frame and it's R-value, and do not give an overall picture. Others avoid R-value or U-value ratings altogether. Tested in nationally certified labs and their own modern test facilities. All of our window manufacturers windows are engineered to provide the optimum in energy savings and are rated by the National Fenestration Rating Council.
	What about strength protection and noise reduction?
	You should look for a window that offers both superior strength and energy efficiency. Our manufacturer's computer controlled processes ensure perfectly square window sashes and mainframes with superior strength. And for exceptional energy efficiency, an interlock at the meeting rail helps protect your home against the elements or unwanted intrusions. In addition, the insulating glass units trap dry air, creating an exceptional comfort barrier.
	Will your vinyl windows be a good investment?
	Yes, for a variety of reasons. First, you may realize significant savings on your heating and cooling bills that others won't with aluminum windows or some wood products. Second, they're virtually maintenance free, which eliminates painting and other maintenance costs. And, finally, all of our manufacturers offer a solid Lifetime Limited Warranty for your peace of mind.
	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 manufacturers use the latest technology, known as high performance warm edge spacer system. This space system helps to improve the performance and the longevity of the insulated glass unit, and is standard on all our windows.
	Can I design any window configuration that I want?
	Pretty much, since all or our windows are custom-made. No matter what style or combination of styles you choose, We can probably custom-manufacture it for you, including the combinations, which require special shaped windows.
	What should I look for in a new construction window?
	You should certainly consider custom-sized windows because they will adapt easier to any special design configuration that your architect may present to you. Stock sized windows might require extensive carpentry work and are often not available sizes to suit your design. Custom-sized windows, on the other hand, are manufactured to fit your designated window opening. You get the style and options you want while maintaining your glass area.
