Selecting Replacement Windows: What Makes a Window Energy Efficient

When you’re starting your project for replacement windows in Terre Haute, energy efficiency should top your priority list. That’s due to the fact inefficient windows can be responsible for the biggest heating and cooling loss in your residence.

They can release as much as 30% of your heating and cooling, according to the U.S. Department of Energy. So, it’s essential that your replacement windows are the best option for the temps in Terre Haute.

In designing your new windows, here are a few things to think over.

Window Panes: One, Two or Three?

Window panes are one of the most important pieces of an energy-efficient window. We recommend going with at minimum double-pane windows, since single-pane windows are very inefficient. They’re also liable to leaking air and impacting your house’s comfort.

If your budget allows it, installing ENERGY STAR® windows will help reduce energy bills and save you more money over the years. That’s since they work hard to keep your house’s ambiance in balance, regardless of the conditions outside.

On average, ENERGY STAR says regular residences that get these windows can save*:

  • $101–$583 yearly when replacing single-pane windows.
  • $27–$197 yearly when replacing double-pane, clear glass windows.

Over the life span of your windows, those savings can really collect. And you can also feel good being aware you’re helping reduce greenhouse gas emissions, which helps protect the environment.

Energy efficiency is critical to us at Pella. That’s why we’ve associated ourselves with ENERGY STAR since 1999 and offer windows that meet or exceed certification in all 50 states. Windows from our Architect Series®, Lifestyle Series, 350 Series and 250 Series are included on the ENERGY STAR Most Efficient 2020 list. This means they’re among the most efficient that you can get.

Customize Your Windows with Glass Options

Adding special coatings and gas between window panes can keep your house cozier while blocking additional ultraviolet rays. Regardless of where you call home, Pella offers an InsulShield® glass style that will work for your specific climate.

Selecting the Ideal Window Frame Material

When selecting your updated windows, you’ll have a couple of materials to select from. Here’s how they rate for energy efficiency:
