Designing Replacement Windows: What Makes a Window Energy Efficient

Designing Replacement Windows: What Makes a Window Energy Efficient

When you’re planning your project for replacement windows in Bloomington, IN, energy efficiency should be number one on your priority list. That’s because inefficient windows can be responsible for the biggest heating and cooling loss in your residence.

They can lose 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 wisest fit for the temps in Bloomington, IN.

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 essential pieces of an energy-efficient window. We advise going with at minimum double-pane windows, due to the fact single-pane windows are notoriously inefficient. They’re also prone to leaking air and impacting your residence’s comfort.

If it will work with your budget, upgrading to ENERGY STAR® windows will help reduce utility expenses and save you more money over the long run. That’s since they work hard to keep your house’s temp in balance, regardless of the weather outside.

On average, ENERGY STAR says normal residences that install 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 cycle of your windows, those savings can really collect. And you can also feel good knowing you’re helping decrease greenhouse gas emissions, which helps shield the environment.

Energy efficiency is important to us at Pella. That’s why we’ve partnered 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 install.

Enhance Your Windows with Glass Options

Using special coatings and gas between window panes can keep your house comfier while keeping out additional ultraviolet rays. Wherever you live, Pella provides an InsulShield® glass style that will work with your personal climate.

Picking the Right Window Frame Material

When selecting your modern windows, you’ll have several materials to pick from. Here’s how they rate for energy efficiency:

  • Top insulation: Wood windows rank high for insulation, as wood intrinsically transfers a smaller amount of heat and cold.
  • High durability: Our exclusive fiberglass windows insulate similarly to wood, besides they won’t melt or break down when experiencing temperature shifts. Designed 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 enhance efficiency.

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

That’s why you’ll want to select with a company like Pella of Bloomington, IN, who specializes in this service. We employ exclusive installation methods to assure your new windows are an excellent fit. This stops gaps and cracks that can allow in moisture and air that impact your comfort.
