This is also a very important part of the replacement process when it comes to windows. Choosing a window frame is as important as the glass itself. The three main types of frames used when buying replacement windows are: vinyl, wood and thermally broken aluminum. Here is a rundown of each:
* Vinyl: These frames have seen soaring improvements in quality as of late. They have a somewhat negative reputation because of their past performance. But today, vinyl is made with an increased level of durability and is virtually maintenance free. It is the same color throughout the frame, which means blemishes go unnoticed. Quality vinyl windows are help in place through welding, instead of screws, which means great reinforcement. They are available in white or beige, which means that they won’t overheat. Vinyl window frames should be certified by the National Fenestration Rating Council and the air space between the two panes of glass should always be at least half of an inch.
* Thermal break aluminum frames: These frames contain a specific thermal barrier that keeps the frame from conducting heat or cold. However, it should be noted that this window frame type is not as energy efficient as vinyl or wood. Thermal frames should also be certified by the National Fenestration Rating Council and have an air space of half an inch between panes. There should also be interlocking sashes and double locks on all windows exceeding 30 inches.
* Wood frames: Wood window frames are a great choice and should have some of the same specifications at the former two frames, with certification through the National Fenestration Rating Council and a half inch of air space. It is also important to use wood types that won’t warp once installed. Wood window frames will always be more expensive but they are always rated the highest frames from consumer reports.
