Choosing Replacement Windows: What Makes a Window Energy Efficient

Choosing Replacement Windows: What Makes a Window Energy Efficient

When you’re beginning your project for replacement windows in Ketchum, energy efficiency should be number one on your priority list. That’s due to the fact 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 important that your replacement windows are the smartest match for the weather in Ketchum.

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

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, as single-pane windows are notoriously inefficient. They’re also subject to leaking air and affecting your home’s comfort.

If your budget allows it, upgrading to ENERGY STAR® windows will help lower energy costs and save you more money over the years. That’s due to the fact they work hard to keep your home’s temp in balance, no matter the climate outside.

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

  • $101–$583 yearly when replacing single-pane windows.
  • $27–$197 each year 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 decrease greenhouse gas emissions, which helps protect the environment.

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

Customize Your Windows with Glass Options

Adding special coatings and gas between window panes can keep your home comfier while stopping extra ultraviolet rays. Regardless of where you reside, Pella offers an InsulShield® glass solution that will work for your individual climate.

Selecting the Ideal Window Frame Material

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

  • Top insulation: Wood windows stack up very well for insulation, as wood inherently transfers a smaller amount of heat and cold.
  • High durability: Our exclusive fiberglass windows insulate almost identically to wood, besides they won’t melt or break down when faced with temperature shifts. Engineered for lasting durability, Pella’s proprietary fiberglass is the strongest material available for windows.**
  • Budget-friendly: Our vinyl windows are designed to match your budget while keeping your residence energy-efficient. Including several chambers, these frames help limit heat loss and increase efficiency.

Quality Window Installation Matters

Excellent installation is just as essential 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 Ketchum, who is knowledgeable about this service. We use exclusive installation methods to assure your new windows are a good fit. This avoids gaps and cracks that can allow in moisture and air that affect your comfort.

You can also count on our team to be thoughtful toward your house during your no-mess, no-guess installation day. They’ll clean up after themselves and will even take away your old windows.
