When it’s time to replace your home’s windows, you will probably want to choose models that are energy efficient. Choosing energy-efficient windows will not only make your house look great, but will also save you money on your monthly energy costs. The better your house is insulated, the more efficiently its heating and cooling systems will work to your advantage. Also, with beautiful new windows, you are able to take advantage of natural light and refrain from turning on your interior lights. When choosing new energy-efficient windows, there are four factors to consider:

Windows in Charlotte, NC1. Glass – While the material that the window is constructed from is important, glass is equally as important in energy-efficient windows. Look for low-e, argon-filled, double-paned windows that will provide greater insulation than a single-paned window. These windows will protect the inside of the house from the sun’s heat and UV rays in the summer, as well as prevent heat from escaping in the winter.

2. Design – Some window designs are inherently more efficient than others. Casement windows are used in areas where high winds are an issue, so they seal themselves tighter to escaping air. Double-hung windows are the most traditional type seen in homes; however, in extreme climates, they are not the best option because of the potential for air to come in between the sliders.

3. Frame – There are a variety of different materials available for window frames and each has its own pros and cons. Dependent on your style and budget, you can choose between vinyl, wood, aluminum, or wood-clad frames to help your energy-efficient windows work at peak performance.

4. Installation – No window is going to be energy efficient if it is not installed properly. Be wary of any contractor who relies too heavily on foams or sealants to get a window to fit well, since these materials aren’t waterproof and can lead to future problems. Flashing and proper caulking need to be done with an eye to detail to ensure there are no water or air leaks.
