How to Choose Energy-Efficient Windows for New Construction Homes

As a construction professional, you know how critical it is to have the right materials for your work. However, with various products out there, it can be difficult to find what's right for your project and for the people who eventually purchase the home you build.

That’s where our window pros can help. We specialize in matching you with products that provide comfort while keeping energy costs low. Let’s review what to consider when choosing energy-efficient windows for new construction homes.

5 Things to Consider When Choosing Energy-Efficient Windows

When it comes to choosing energy-efficient windows, there are several factors you’ll need to consider.

1. Material

Premium wood windows are desired for their warmth, design flexibility and energy efficiency. Wood is a low conductivity material, as it exchanges less heat and cold.

Fiberglass windows are another good option, since they supply insulation similar to wood. Even when exposed to shifting temperatures, the material won’t warp or break down. In fact, our proprietary fiberglass is the strongest material available for windows.1

If your clients are on a budget, vinyl windows are still a good choice for energy efficiency. Ours have multiple chambers for additional insulation. And they’re easy to care for.

Some of our windows can be customized with optional foam insulation to improve energy performance.

2. Number of Panes

Energy-efficient windows are typically dual- or triple-pane. The more panes of glass a window includes, the more energy efficient it is.

3. Glass Options

Inert argon gas can be placed between panes for greater energy efficiency and reduced thermal transfer.

You can also select from insulating glass options such as laminated, tempered, tinted or obscure glass. Low-emissivity glass coatings help keep heating and cooling where it belongs, plus they can also stop UV rays to keep artwork, furniture and flooring looking its best.

Our InsulShield® glass collection provides the most innovative energy-saving choices, created for your specific climate types.

4. Energy-Efficiency Ratings

We offer windows that meet or exceed ENERGY STAR® ratings.2 Here are a few benefits of installing ENERGY STAR windows in a new construction home:

  • Can reduce energy bills by up to 12%, when compared with non-certified windows.
  • Can save between $101-$583 each year, when compared to single-pane windows.
  • Can save between $27-197 each year, when compared to dual-pane windows.

Your clients’ actual savings will vary based on the local climate, utility prices and unique home characteristics.

Other ratings to think about include R-value and U-value, which measure how effectively windows stop airflow, as well as their level of heat transfer.

When you’re concerned about energy efficiency, the R-value of the windows you choose should be higher than R-5. The U-value should be between 0.2–1.2, according to the U.S. Department of Energy.

5. Window Style

Choosing the right window style for your location can also help with future homeowners’ energy bills. Here’s what we encourage, based on location and prominent architectural styles:

  • Northeast: single-hung, double-hung, casement, sliding
  • Northwest: bay or bow, casement
  • Midwest: casement
  • South: double-hung
  • Coastal: bay or bow, casement, sliding
