Can Energy-Efficient Insulating Windows Really Save You Money?




There are a lot of “quick fixes” out there, like caulking and weatherstripping, that promise to improve your windows’ insulation and reduce air leakage.  But the reality is, these are not long-term solutions and they rarely do much to make a noticeable difference in your heating and cooling costs.

If your home has old or inefficient windows, you may be wondering  ̶  should I purchase energy-efficient replacement windows?  Will they help me save on energy costs? Will my investment pay off in the long run?  What do all the ratings mean, and what windows should I consider?

XO Windows is Arizona’s largest window distributor, and we’ve got the answers. Keep reading to find out how our new MI EnergyCore™ windows can help you lower your energy bills and keep your home more comfortable.

First, What do All Those Ratings Mean?

Understanding performance ratings is the first step to knowing what type of windows are best for your home and climate. In Arizona, we have the challenge of keeping a home cool and comfortable despite extreme heat and high solar radiation.

Here are some terms you should know:

U-factor:  A window’s U-factor measures the amount of heat transfer, making it a marker of the window’s insulation. The range is usually between 0.25 and 1.25; the lower the number, the more energy efficient the window.

Performance Grade:  The American Architectural Manufacturers Association (AAMA) gives this numeric rating, which defines the overall performance of a product.

R-value:  The R-value measures thermal resistance; it refers to how much a window resists heat conduction.  A high R-value indicates a more energy-efficient window.

What Makes a Window Energy Efficient?

There are several factors that make a window more or less energy efficient; these include:

The frame can affect the window’s resistance to heat conduction and is typically wood, fiberglass, aluminum or PVC.

The glass works to absorb solar radiation; reflective coatings or glazing filter out heat. Double- or triple-paned glass is more energy efficient than single-paned windows.

The design can be based on the window’s shape and orientation, climate, style, security and functionality. Windows designed with insulating factors and quality construction in mind will make the window more resistant to water and air penetration.

Save Money with MI EnergyCore Windows

For consumers who want stylish windows, maximum performance and optimal energy efficiency, the MI EnergyCore Window System can’t be beat. Let’s take a look at what these windows provide in terms of energy efficiency:

MI EnergyCore windows are manufactured with patented AirCell™ PVC frame technology, which provides multiple air and water barriers. This frame blocks thermal conductivity better than any other material  ̶  3 times more than wood, 4 times more than rigid PVC and 6 times more than fiberglass.  The frame supports many residential window sizes and styles.

Along with an energy-efficient frame, TMAX™ Insulating Glass is argon-filled and triple-paned. The extra barriers to heat transfer gives it a superior thermal performance, and improved sound control reduces noise.

The design is engineered to provide multiple air/water barriers such as improved weatherstripping,  interlocking meeting rails and maximum draining sills, which all help keep your home dry.

All MI EnergyCore windows have an AAMA Performance Grade of at least 40.

The windows have an R-value of 5 and U-factor of 0.2, exceeding ENERGY STAR® standards and placing them in the top tier of energy-efficient windows available today.

What Does this Mean for You?

MI EnergyCore insulating windows have been proven to reduce heat loss by 30-40%, and your energy bill will reflect those numbers. The more heat you can keep IN your home in the winter, and OUT of your home in the summer, the less you have to pay at the end of the month.

When these award-winning windows are properly installed, they can truly help maximize your home’s performance and comfort and minimize your heating and cooling costs.

If you’re ready to make your home more energy efficient, contact XO Windows to find out if MI EnergyCore windows are right for you.
