Windows have the challenging feat of trying to let light in while keeping weather out. And though this seems a simple process, it is actually quite difficult considering that windows actually provide a poor barrier to radiant energy and inclement weather.

Most people compensate for inadequate windows by augmenting with heating and cooling systems instead. A better, and more cost efficient remedy would be to inspect your current windows and research available replacement window options. Because the fact still remains that the wrong window could be costing you much more than you realize.

Types of Replacement Windows

When selecting a replacement window, there are many quality products, variety of styles, colors, and materials to choose from. Before you begin your search, consider your homes' architectural style, amount of windows in your home, the climate you live in, and your budget constraints. The following types of windows can provide you with a good starting point.

1. Single-pane. These provide little, if any, insulation and are comprised of a single piece of glass encased between a wood or vinyl frame.
2. Double-pane. These energy efficient windows provide a buffer zone of air between two panes of glass. They can significantly reduce heat loss and add a great deal of insulation.
3. Low Emissive Coating. These windows utilize a micro-think metallic coating that reflects heat and helps to improve the thermal quality of double-pane windows.
4. Spectrally Selective Coating. This coating blocks selected rays from entering the home and helps to protect sun bleaching. The coating is built into the glass and can offer privacy dark-to-light options.
5. Window Casings. Choose between vinyl, wood, and aluminum, as well as a variety of colors and stains.

What is an Energy Efficient Replacement Window?

According to a national energy survey, replacing single-paned windows with double-paned ones can save the average consumer 75 cents on the dollar, as compared to heating and cooling alternatives. Most window manufacturers today represent a windows' energy efficiency in terms of a U-value (conductance of heat) or an R-value (resistance to heat flow). Look for one with a high R-value or a low U-value (.35 or lower is considered quite good).

With dealer and tax incentives, coupled with a 20-year warranty, offered for most windows, you can't help but offset your current energy costs with new replacement windows.
