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 lose up to a third 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 Kelowna, you’ll want to select the most energy-efficient option possible. At Pella of Kelowna, our front entry doors are constructed 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 preferences.

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

Fiberglass Exterior Doors

When you’re choosing an insulation type for your home, there’s a reason why fiberglass is the most common. It doesn’t conduct heat very well, keeps temperatures pleasant and withstands moisture. The same can be said about fiberglass exterior doors, which are considered one of the top picks for energy-efficient doors.

As an added bonus, fiberglass:

  • Has lower expansion and contraction, making them perfect if you reside somewhere notably hot or cold.
  • Doesn’t need a lot of maintenance, such as painting.
  • Naturally resists dents and scratches.

At Pella of Kelowna, you’ll have full access to a wide number of models that fit your home’s unique style, including solid and glass fiberglass doors.

While a glass pane is an easy way to introduce 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 Kelowna.

Our glass selections range from 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 can’t insulate as well as fiberglass, it’s still a great choice for your front door, namely if you want added security. Steel exterior doors are consistently tough, which guarantees extensive durability against wind and rain damage. Like fiberglass, steel doesn’t rely on much maintenance like painting.

At Pella of Kelowna, our steel doors come in three popular traditional and contemporary styles, two-panel square, six panels and flush. You’ll have the option to choose from a clean white or a primed finish, so your door can be whichever color you’d like.

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

Other Things to Think About When Upgrading Your Exterior Door

Now that you’ve narrowed down the material you want, there are a couple other things you want to consider when purchasing new entry doors.

You Likely Don’t Need a Storm Door

When starting your door replacement project, you could possibly be wondering whether it’s worth adding a storm door, namely if you previously had one. The U.S. Department of Energy argues this typically isn’t worth the additional cost and won’t save you that much more energy. This combo is typically only worth it if you have an older door that’s in good 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 choice, as well as the weather in Kelowna and your home’s unique 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 warmer in the winter with higher numbers. Choosing the ideal combination should help with better balancing indoor temperatures.

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

For the best performance and energy efficiency, look for doors that are ENERGY STAR® certified. Doors that hold this certification use multiple panes of glass to cut down on heat flow, stronger core materials for extra insulation and a precise seal to decrease energy loss.

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