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 can cost you in terms of energy efficiency. That’s because ill-fitting or inefficient ones can leak up to 30% of your home’s heating or air conditioning, according to the Department of Energy.

When you’re swapping out your home’s exterior doors in Decatur, you’ll want to pick the most energy-efficient option possible. At Pella of Decatur, our front entry doors are manufactured with energy efficiency and long-term performance in mind. And you’ll have the chance to customize them for your home, with just the right hardware, color and glass features for your preferred designs.

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

Fiberglass Exterior Doors

When you’re deciding on 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 comfortable and withstands moisture. The same can be said about fiberglass exterior doors, which are typically one of the top choices for energy-efficient doors.

As an additional bonus, fiberglass:

  • Has reduced expansion and contraction, making them perfect if you reside somewhere especially hot or cold.
  • Doesn’t need a lot of upkeep, such as painting.
  • Naturally resists dents and scrapes.

At Pella of Decatur, you’ll have total access to a broad number of choices that complement your home’s unique style, including solid and glass fiberglass doors.

While a glass pane is a great way to provide more natural light into your home, you might be concerned if it will make the door less insulating. With energy-efficient glass as an option, you’re sure to find a style that suits the temperatures in Decatur.

Our glass selections range from full light to one-quarter light, with optional glazed glass for additional 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 won’t insulate as well as fiberglass, it’s still an excellent option for your front door, namely if you want extra security. Steel exterior doors are naturally tough, which guarantees substantial durability against severe weather. Like fiberglass, steel doesn’t need much maintenance like painting.

At Pella of Decatur, our steel doors are offered in three attractive traditional and contemporary styles, two-panel square, six panels and flush. You’ll have the chance to pick from a clear white or a primed finish, so your door can be any color you’d want.

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

Other Things to Consider When Upgrading Your Exterior Door

Now that you’ve narrowed down the material you want, there are a few other things you ought to have in mind when purchasing new entry doors.

You Likely Don’t Need a Storm Door

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

Don’t Forget to Examine Energy Performance Ratings

Every entry door has an energy-efficiency rating from the National Fenestration Rating Council. You’ll want to keep this in mind when making your decision, as well as the weather in Decatur and your home’s unique design. This rating covers solar heat gain and U-factor.

For solar gain ratings, you’ll have a chance to keep your home more comfortable in the summer with lower numbers and cozier in the winter with higher numbers. Selecting the ideal combination will help with better balancing indoor temperatures.

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

For the highest performance and energy efficiency, look for doors that are ENERGY STAR® certified. Doors that possess this certification have multiple panes of glass to reduce heat flow, superior core materials for improved insulation and a precise seal to reduce energy loss.

These types of doors sometimes decrease your energy costs while making your home more comfortable. And less energy needs means more protection for the environment and natural resources. At Pella, we’ve been a proud partner with ENERGY STAR since 1999 and offer many models that meet or exceed ENERGY STAR certification standards in all 50 states.
