Best Exterior Doors for Insulation

Windows and doors are a great 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 leaky or inefficient ones can lose up to thirty percent of your home’s heating or air conditioning, according to the Department of Energy.

When you’re upgrading your home’s exterior doors in Ketchum, you’ll want to pick the most energy-efficient option out there. At Pella of Ketchum, our front entry doors are constructed 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 style.

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 withstands moisture. The same can be said about fiberglass exterior doors, which are considered one of the top choices for energy-efficient doors.

As an additional bonus, fiberglass:

  • Has lower expansion and contraction, making them better-suited if you are living somewhere particularly hot or cold.
  • Doesn’t depend on a lot of upkeep, such as painting.
  • Naturally resists dents and scratches.

At Pella of Ketchum, you’ll have complete access to a wide range of models that complement your home’s unique design, including solid and glass fiberglass doors.

While a glass pane is a good 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 to choose from, you’re sure to find a style that works with the weather in Ketchum.

Our glass selections consist of 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 a good material for your front door, particularly if you want extra security. Steel exterior doors are naturally tough, which guarantees substantial durability against wind and rain damage. Like fiberglass, steel doesn’t require much maintenance like painting.

At Pella of Ketchum, our steel doors come in three fashionable traditional and contemporary styles, two-panel square, six panels and flush. You’ll be able to choose from a striking white or a primed finish, so your door can be any color you’d prefer.

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

Other Things to Consider When Replacing Your Exterior Door

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

You Probably Don’t Need a Storm Door

When starting your door replacement project, you may be wondering whether it’s beneficial to add a storm door, namely if you previously had one. The U.S. Department of Energy states this usually isn’t worth the additional cost and won’t save you that much more energy. This combination is typically only recommended if you have an older door that’s in solid condition but needs extra insulation.

Don’t Forget to Assess 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 Ketchum 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 perfect combination should help with better regulating indoor temperatures.

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

For the best performance and energy efficiency, look for doors that are ENERGY STAR® certified. Doors that bear this certification have multiple panes of glass to restrict heat flow, stronger core materials for enhanced insulation and a firm seal to decrease energy loss.

These types of doors sometimes reduce your energy bills while making your home more comfortable. And less energy needs means added protection for the environment and natural resources. At Pella, we’ve continued to be a proud partner with ENERGY STAR since 1999 and offer many products that meet or exceed ENERGY STAR certification standards across the country.
