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 might cost you in terms of energy efficiency. That’s because ill-fitting or inefficient ones can leak up to thirty percent 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 Casper, you’ll want to choose the most energy-efficient option on the market. At Pella of Casper, our front entry doors are made with energy efficiency and long-term performance in mind. And you’ll have the opportunity 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 selecting an insulation type for your home, there’s a reason why fiberglass is the most popular. It doesn’t conduct heat very well, keeps temperatures comfortable and repels moisture. The same can be said about fiberglass exterior doors, which are thought of as one of the top picks for energy-efficient doors.

As an additional bonus, fiberglass:

  • Has miminal expansion and contraction, making them better-suited if you live somewhere especially hot or cold.
  • Doesn’t need a lot of maintenance, such as painting.
  • Naturally resists dents and scratches.

At Pella of Casper, you’ll have total access to a broad variety of choices that adhere to your home’s unique style, 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 as an option, you’re guaranteed to find a style that works with the climate in Casper.

Our glass selections include full light to one-quarter light, with optional glazed glass for extra 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 a good material for your front door, namely if you want additional security. Steel exterior doors are naturally tough, which offers long-lasting durability against severe weather. Like fiberglass, steel doesn’t depend on much maintenance like painting.

At Pella of Casper, our steel doors come in three popular traditional and contemporary styles, two-panel square, six panels and flush. You’ll have the option 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 quality hardware brand, so you’ll have additional security features for your steel door and extra peace of mind.

Other Things to Contemplate When Replacing Your Exterior Door

Now that you’ve picked out the material you want, there are a small number of other things you ought to have in mind when purchasing new entry doors.

You Generally Don’t Need a Storm Door

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

Don’t Forget to Check 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 Casper and your home’s specific design. This rating covers solar heat gain and U-factor.

For solar gain ratings, you’ll be able to keep your home more comfortable in the summer with lower numbers and warmer in the winter with higher numbers. Picking the ideal combination should help with better stablizing indoor temperatures.

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

For the highest performance and energy efficiency, consider doors that are ENERGY STAR® certified. Doors that bear this certification have multiple panes of glass to reduce heat flow, resilient core materials for enhanced insulation and a firm seal to prevent energy loss.

These types of doors can decrease your energy bills while making your home more comfortable. And lower energy use 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 across the country.
