Choosing Replacement Windows: What Makes a Window Energy Efficient

Choosing Replacement Windows: What Makes a Window Energy Efficient

When you’re starting your project for replacement windows in Decatur, energy efficiency should top your priority list. That’s due to the fact inefficient windows can be responsible for the largest heating and cooling loss in your residence.

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 solution for the weather in Decatur.

In selecting your new windows, here are a few things to think over.

Window Panes: One, Two or Three?

Window panes are one of the most critical 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 subject to seeping air and affecting your residence’s comfort.

If it will fit your budget, switching to ENERGY STAR® windows will help decrease heating and cooling expenses and save you more money in the future. That’s because they work hard to keep your home’s ambiance in balance, despite the weather 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 accrue. And you can also feel good being aware you’re helping reduce greenhouse gas emissions, which helps protect 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 included on the ENERGY STAR Most Efficient 2020 list. This means they’re among the most efficient that you can buy.

Individualize Your Windows with Glass Options

Using special coatings and gas between window panes can keep your house more comfortable while keeping out additional ultraviolet rays. Wherever you call home, Pella offers an InsulShield® glass option that will work with your personal climate.

Selecting the Right Window Frame Material

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

  • Top insulation: Wood windows stack up very well for insulation, because wood naturally transfers a smaller amount of heat and cold.
  • High durability: Our exclusive fiberglass windows insulate similarly to wood, along with the fact they won’t melt or break down when exposed to temperature shifts. Made 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 residence energy-efficient. With numerous chambers, these frames help limit heat loss and boost efficiency.

Quality Window Installation Matters

Quality 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 go with a company like Pella of Decatur, who is knowledgeable about this service. We employ exclusive installation methods to assure your new windows are a good fit. This stops holes and cracks that can let in moisture and air that compromise your comfort.
