What is the Energy Star Certification?

Energy Star is an international standard for energy-efficient consumer products. This same standard applies to many products such as kitchen appliances, building products, computers, etc.

The Energy Star window certification program in the United States is designed to help you select energy-efficient windows optimized for your climate.

Energy Star replacement windows must meet minimum performance criteria to qualify for Energy Star certification. The NFRC criteria are based on whole window performance ratings and are different for each of the four United States climate zones as follows:

  • Northern Zone: U-Factor of .27 or less, SHGC any
  • North Central Zone: U-Factor of .30 or less, SHGC of .40 or less
  • South Central Zone: U-Factor of .30 or less, SHGC of .25 or less
  • Southern Zone: U-Factor of .40 or less, SHGC of .25 or less

Colorado Springs is in the northern zone.

All of The Window Source replacement windows and doors we sell are available with our energy star replacement windows upgrade.


What does Low-E mean for my windows?

The term Low-E means low emissivity. Low-E is a coating treatment applied to the window pane.

When a window is treated with Low-E the surface emits lower levels of radiant heat. All surfaces reflect, absorb, and transmit heat. A Low-E coating reduces the amount of heat transfer through the window.

Hence, the Low-E coating reflects heat, so your home stay cooler in the summer and warmer in the winter.

The Low-E coating is applied to the inside of the pane, so it won’t scratch off.

In addition, Low-E protects against UV fading of any furniture that receives direct sunlight.

We guarantee the certification of our Energy Star replacement windows, so you will receive the best Low-E that is optimized for the Pikes Peak region.

What are the advantages of Argon Gas?

Window efficiency is further improved by using Argon gas to fill the space between the panes.

Argon gas is denser than air and therefore provides more thermal efficiency than having air between the panes. The Argon gas acts as an insulator, working in both summer and winter to protect your home from outside temperatures.

Argon gas also helps prevent frost from forming at the bottom of a window and improves the sound barrier capability of a window, thus lowering the noise in your home from outside sources.

Argon gas is odorless and non-toxic and should last the lifetime of a double-glazed window.

How much do high-efficiency replacement windows in Colorado Springs cost?

Our High-Performance Package energy efficiency option is an add on cost to our replacement windows and doors.  The cost of this treatment varies depending on window style and size.

You can expect this treatment to add to the cost of each window, but keep in mind the price will vary depending on the size and style of a particular window.

Will I get a return on investment by installing energy-efficient replacement windows?

The return on investment from lower utility bills depends on the type of windows you are replacing, and the style of window you are installing.

Did you know a gap in your window frames as small as 1/16 of an inch lets in as much cold air as leaving the window open three inches?

If you have old, leaky single-pane windows with wood or aluminum frames then you are going to enjoy a significant reduction in utility bills.  We often see savings of 25% or more.

Window style is also a factor in improving the energy efficiency of your home.

Picture windows, casement windows and hopper windows are the most energy-efficient styles of windows. This is due to the air-tight nature of the design of these windows.

Therefore, you need to factor window style, window size, and the condition of your existing windows into your energy savings calculations.

You should also consider the increased value of your Colorado Springs home that will result when you install new high-efficiency replacement windows.  Your home will be both worth more and gain curb appeal after you upgrade your windows.
