Designing Replacement Windows: What Makes a Window Energy Efficient

Designing Replacement Windows: What Makes a Window Energy Efficient

When you’re starting your project for replacement windows in Owensboro, energy efficiency should be at the top of your priority list. That’s due to the fact inefficient windows can be responsible for the greatest 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 crucial that your replacement windows are the wisest fit for the temperatures in Owensboro.

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 critical pieces of an energy-efficient window. We advise choosing no less than double-pane windows, since single-pane windows are especially inefficient. They’re also subject to leaking air and impacting your house’s comfort.

If it will fit your budget, switching to ENERGY STAR® windows will help reduce heating and cooling costs and save you more money in the future. That’s since they work hard to keep your house’s temperature in balance, despite the climate outside.

On average, ENERGY STAR says regular houses that get these windows can save*:

  • $101–$583 annually 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 knowing you’re helping reduce greenhouse gas emissions, which helps shield the environment.

Energy efficiency is important 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 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

Adding special coatings and gas between window panes can keep your home more comfortable while blocking extra ultraviolet rays. Regardless of where you call home, Pella provides an InsulShield® glass style that will work with your personal climate.

Selecting the Ideal Window Frame Material

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

  • Top insulation: Wood windows rank very well for insulation, since wood inherently transfers a smaller amount of heat and cold.
  • High durability: Our exclusive fiberglass windows insulate similarly to wood, plus 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 work with your budget while keeping your residence energy-efficient. With numerous chambers, these frames help limit heat loss and boost efficiency.

Quality Window Installation is Important

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

That’s why you’ll want to select with a company like Pella of Owensboro, who is skilled in this service. We employ exclusive installation methods to assure your new windows are a good fit. This prevents gaps and cracks that can let in moisture and air that compromise your comfort.
