Genuine wood has a look and a feel to it that nothing else can match. Wood is classic; wood is solid; wood is the real deal. Virtually all other window frames attempt to mimic the look of wood. Genuine wood frames help to insulate a home far better than almost any other kind of window. Real wood provides 400 times more insulation than steel window frames and 1,800 times as much as aluminum-frame windows. The additional insulation that real wood provides can help keep a home warm in the winter and cool in the summer and can save the homeowner on utility bills all year round. Wood-framed windows also provide an excellent barrier to outdoor sounds”much more so than virtually any other frame.
