You want to replace your windows to lower the energy consumption of your home and lessen the carbon footprint, but deciding to do so is only the first of many decisions to make before the new panes are installed. The types of windows to choose from are numerous, and prices vary greatly; therefore, it is important to be informed about available window options. Here are three critical factors in choosing the perfect replacement windows for you.

Climate Is Key

Many double-pane and triple-pane windows are factory sealed with argon gas used as an insulating factor. Argon gas is heavy enough to slow the transfer of heat between indoors and outdoors, thus keeping your home cooler in the summer and warmer in the winter. Look for the low-e transparent reflection window coating for energy efficiency as well. Your area’s climate may often determine which type of window is preferable, but look beyond the number of window panes and choose a window with openings most appropriate to the climate.

Performance and Location Are Significant

Window location often determines which type of replacement windows you need. Fixed windows will not open, but they may have a high thermal performance rating due to the lack of gaps and possible air leaks. Casement windows are next in efficiency because of the seals that compress when the glass is cranked closed, and these awning-type closures are great at preventing leaks. The sliders are less efficient, but many people prefer this style of window because of the ease of opening and closing the large panes.

Numbers Are Necessary

The National Fenestration Rating Council rates windows for homes and businesses. One of the most important rating numbers is the U-factor. Make sure the window is marked “AA” for residential use, and then check the U-factor. The lower the numbers, the better the insulation will be for your home. These figures are an excellent way to compare different types and glass styles, and to find the perfect replacement windows for your home.
