Choosing Replacement Windows: What Makes a Window Energy Efficient

Choosing Replacement Windows: What Makes a Window Energy Efficient

When you’re planning your project for replacement windows in Casper, energy efficiency should top your priority list. That’s since inefficient windows can be responsible for the largest 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 match for the temps in Casper.

In picking your new windows, here are a few aspects to keep in mind.

Window Panes: One, Two or Three?

Window panes are one of the most critical parts of an energy-efficient window. We suggest going with no less than double-pane windows, since single-pane windows are very inefficient. They’re also vulnerable to seeping air and influencing your home’s comfort.

If your budget allows it, switching to ENERGY STAR® windows will help decrease heating and cooling expenses and save you more money over the long run. That’s because they work hard to keep your house’s temp in balance, regardless of the weather outside.

On average, ENERGY STAR says normal residences that upgrade to these windows can save*:

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

Over the lifetime of your windows, those savings can really add up. And you can also feel good knowing you’re helping reduce greenhouse gas emissions, which helps shield the environment.

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

Individualize Your Windows with Glass Options

Adding special coatings and gas between window panes can keep your house comfier while blocking additional ultraviolet rays. Wherever you live, Pella has an InsulShield® glass style that will work for your individual climate.

Selecting the Right Window Frame Material

When creating your updated windows, you’ll have a few materials to select from. Here’s how they rank for energy efficiency:

  • Top insulation: Wood windows stack up very good for insulation, because wood naturally transfers a lesser amount of heat and cold.
  • High durability: Our exclusive fiberglass windows insulate much like wood, along with the fact they won’t melt or break down when experiencing temperature swings. Designed for lasting durability, Pella’s proprietary fiberglass is the strongest material available for windows.**
  • Budget-friendly: Our vinyl windows are created to match your budget while keeping your house energy-efficient. Including multiple chambers, these frames help limit heat loss and increase efficiency.

Quality Window Installation is Important

Excellent installation is just as important as the glass and window frame material you select for your new windows.

That’s why you’ll want to choose with a company like Pella of Casper, who is skilled in this service. We follow exclusive installation methods to ensure your new windows are an excellent fit. This avoids holes and cracks that can allow in moisture and air that compromise your comfort.

You can also trust our team to respect your house during your no-mess, no-guess installation day. They’ll clean up after themselves and will even take care of your old windows.
