There may be several reasons why you should think of replacement windows for your home... If you have an old model home fitted with single pane windows, please understand you are losing a significant amount of energy through the glass both for cooling and heating. Window dressings such as cloth curtains are certainly helpful but the right thing to do is to replace the windows with new, vinyl, double glazed windows. The latest types of windows are much easier to clean than the old wood framed ones.The vinyl windows can be completely cleaned from the inside, making them not only energy efficient but also convenient to maintain. The most popular replacement windows are undoubtedly vinyl because they are easy to install, come in a variety of colors, and does not require painting.
Presently, we find that in most replacement windows, sealed insulated glass has replaced the old single-glazed prime window. Sealed, insulated glass is coated or filled with argon or other gases to further reduce heat loss and raise the window's R-value. Most sealed insulated glass has metal spacers at the edges. Infiltration rating or U-factor is the term used for measuring the window's ability to reduce air leakage through the gaps between the sash and the frame. Look for windows with low U-factor infiltration numbers preferably less than 0.35. To prevent condensation, look for windows that have warm air technology. Building experts opine that casement and awning windows are tighter than double-hung or horizontal slide-by windows. That is because casement and awning windows seal by compressing the sash against the weather strip.
