Designing Replacement Windows: What Makes a Window Energy Efficient

Designing Replacement Windows: What Makes a Window Energy Efficient

When you’re beginning your project for replacement windows in Terre Haute, energy efficiency should be number one on your priority list. That’s since inefficient windows can be responsible for the biggest heating and cooling loss in your house.

They can lose 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 option for the climate in Terre Haute.

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 important components of an energy-efficient window. We recommend going with at least double-pane windows, since single-pane windows are especially inefficient. They’re also predisposed to leaking air and impacting your residence’s comfort.

If your budget allows it, installing ENERGY STAR® windows will help decrease energy bills and save you more money in the future. That’s since they work hard to keep your residence’s temp in balance, no matter the conditions 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 span of your windows, those savings can really collect. And you can also feel good being aware you’re helping reduce greenhouse gas emissions, which helps protect the environment.

Energy efficiency matters 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 included 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 house cozier while blocking additional ultraviolet rays. Regardless of where you call home, Pella provides an InsulShield® glass style that will work for your specific climate.

Selecting the Ideal Window Frame Material

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

  • Top insulation: Wood windows stack up very good for insulation, since wood naturally transfers less 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. Created 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. With several chambers, these frames help decrease heat loss and increase efficiency.

Quality Window Installation is Essential

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

That’s why you’ll want to go with a company like Pella of Terre Haute, who is skilled in this service. We use exclusive installation methods to make sure your new windows are a good fit. This prevents gaps and cracks that can allow in moisture and air that affect your comfort.

You can also depend on our team to respect your house during your no-mess, no-guess installation day. They’ll clean up after they’re done and will even haul away your old windows.
