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 be number one on your priority list. That’s since inefficient windows can be responsible for the largest heating and cooling loss in your house.

They can release as much as 30% of your heating and cooling, according to the U.S. Department of Energy. So, it’s crucial that your replacement windows are the best option for the climate 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 selecting no less than double-pane windows, since single-pane windows are very inefficient. They’re also vulnerable to losing air and influencing your home’s comfort.

If your budget allows it, switching to ENERGY STAR® windows will help reduce utility expenses and save you more money over the long run. That’s because they work hard to keep your house’s ambiance in balance, no matter the weather outside.

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

  • $101–$583 yearly 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 collect. And you can also feel good knowing you’re helping reduce greenhouse gas emissions, which helps defend the environment.

Energy efficiency is critical to us at Pella. That’s why we’ve affiliated 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.

Enhance 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.

Picking the Right Window Frame Material

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

  • Top insulation: Wood windows are rated very well for insulation, because wood naturally transfers a smaller 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 faced with temperature swings. Designed for lasting durability, Pella’s proprietary fiberglass is the strongest material available for windows.**
  • Budget-friendly: Our vinyl windows are made to work with your budget while keeping your house energy-efficient. Including multiple chambers, these frames help limit heat loss and enhance efficiency.

Quality Window Installation is Essential

Good installation is just as important as the glass and window frame material you pick 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 a great fit. This stops openings and cracks that can permit in moisture and air that compromise your comfort.
