Best Exterior Doors for Insulation

Windows and doors are an easy way to add character to your home. But the wrong ones or old ones may cost you in terms of energy efficiency. That’s because leaky or inefficient ones can leak up to a third of your home’s heating or air conditioning, according to the Department of Energy.

When you’re upgrading your home’s exterior doors in Terre Haute, you’ll want to settle on the most energy-efficient option on the market. At Pella of Terre Haute, our front entry doors are designed with energy efficiency and long-term performance in mind. And you’ll have the choice to customize them for your home, with just the right hardware, color and glass features for your preferences.

Here are our top picks for best exterior doors for insulation.

Fiberglass Exterior Doors

When you’re picking out an insulation type for your home, there’s a reason why fiberglass is the most sought-after. It doesn’t conduct heat very well, keeps temperatures stable and resists moisture. The same can be said about fiberglass exterior doors, which are frequently one of the top options for energy-efficient doors.

As an additional bonus, fiberglass:

  • Has low expansion and contraction, making them ideal if you live somewhere notably hot or cold.
  • Doesn’t depend on a lot of extra care, such as painting.
  • Naturally minimizes dents and scratches.

At Pella of Terre Haute, you’ll have full access to a broad range of options that adhere to your home’s unique aesthetic, including solid and glass fiberglass doors.

While a glass pane is a straightforward way to bring more natural light into your home, you might want to know if it will make the door less insulating. With energy-efficient glass available, you’re guaranteed to find a style that works with the weather in Terre Haute.

Our glass selections include full light to one-quarter light, with optional glazed glass for added privacy. You’ll be able to further customize your door with caming, beveling and between-the-glass grilles and blinds.

Steel Exterior Doors

While steel can’t insulate as well as fiberglass, it’s still a great choice for your front door, namely if you want extra security. Steel exterior doors are consistently tough, which ensures extensive durability against wind and rain damage. Like fiberglass, steel doesn’t depend on much maintenance like painting.

At Pella of Terre Haute, our steel doors come in three fashionable traditional and contemporary styles, two-panel square, six panels and flush. You’ll be free to select from a crisp white or a primed finish, so your door can be whichever color you’d want.

We partner with Baldwin, a superior hardware brand, so you’ll have extra security enhancements for your steel door and extra peace of mind.

Other Things to Think About When Replacing Your Exterior Door

Now that you’ve chosen the material you want, there are a small number of other things you want to think about when purchasing new entry doors.

You Typically Don’t Need a Storm Door

When doing your door replacement project, you might be unsure of whether it’s beneficial to add a storm door, particularly if you previously had one. The U.S. Department of Energy suggests this usually isn’t worth the extra cost and won’t save you that much more energy. This combo is typically only useful if you have an older door that’s in good condition but needs added insulation.

Don’t Forget to Review Energy Performance Ratings

Every entry door has an energy-efficiency rating from the National Fenestration Rating Council. You should keep this in mind when making your choice, as well as the weather in Terre Haute and your home’s specific design. This rating includes solar heat gain and U-factor.

For solar gain ratings, you’ll have the opportunity to keep your home cooler in the summer with lower numbers and warm in the winter with higher numbers. Choosing the perfect combination will help with better balancing indoor temperatures.

With U-factor, you’ll want to choose a lower number. This means the door is better at trapping heat inside.

For ideal performance and energy efficiency, try doors that are ENERGY STAR® certified. Doors that hold this certification come with multiple panes of glass to restrict heat flow, superior core materials for improved insulation and a tight seal to prevent energy loss.

These types of doors could slash your energy expenses while making your home more comfortable. And lower energy use means added protection for the environment and natural resources. At Pella, we’ve remained a proud partner with ENERGY STAR since 1999 and offer many doors that meet or exceed ENERGY STAR certification standards in every state.

There’s a reason why Pella is the #1 preferred entry door brand by homeowners.* Our outstanding exterior doors can be customized and you’ll receive useful advice from our staff throughout the process, from your consultation to installation and everything in between.
