Selecting Replacement Windows: What Makes a Window Energy Efficient

Selecting Replacement Windows: What Makes a Window Energy Efficient

When you’re starting your project for replacement windows in Idaho, 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 leak as much as 30% of your heating and cooling, according to the U.S. Department of Energy. So, it’s important that your replacement windows are the best match for the climate in Idaho.

In designing 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 essential parts of an energy-efficient window. We advise going with at minimum double-pane windows, due to the fact single-pane windows are very inefficient. They’re also liable to leaking air and affecting your residence’s comfort.

If it will fit your budget, switching to ENERGY STAR® windows will help decrease energy expenses and save you more money over the years. That’s due to the fact they work hard to keep your residence’s temperature in balance, no matter the climate outside.

On average, ENERGY STAR says regular homes that install these windows can save*:

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

Over the life span of your windows, those savings can really accumulate. And you can also feel good realizing you’re helping minimize greenhouse gas emissions, which helps defend the environment.

Energy efficiency is important 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 listed on the ENERGY STAR Most Efficient 2020 list. This means they’re among the most efficient that you can install.

Customize Your Windows with Glass Options

Including special coatings and gas between window panes can keep your house more comfortable while keeping out more ultraviolet rays. Regardless of where you call home, Pella offers an InsulShield® glass style that will work with your personal climate.

Selecting the Right Window Frame Material

When selecting your new windows, you’ll have a couple of materials to pick from. Here’s how they stack up for energy efficiency:

  • Top insulation: Wood windows are rated very well for insulation, since wood intrinsically transfers less heat and cold.
  • High durability: Our exclusive fiberglass windows insulate similarly to wood, plus they won’t melt or break down when experiencing temperature swings. Engineered for lasting durability, Pella’s proprietary fiberglass is the strongest material available for windows.**
  • Budget-friendly: Our vinyl windows are designed to fit your budget while keeping your house energy-efficient. Featuring multiple chambers, these frames help decrease heat loss and boost efficiency.

Quality Window Installation is Important

Good installation is just as critical as the glass and window frame material you choose for your new windows.

That’s why you’ll want to go with a company like Pella of Idaho, who is knowledgeable about this service. We follow exclusive installation methods to assure your new windows are an excellent fit. This avoids gaps and cracks that can allow in moisture and air that impact your comfort.
