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 could 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 upgrading your home’s exterior doors in Idaho, you’ll want to settle on the most energy-efficient option on the market. At Pella of Idaho, 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 preferred designs.

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 common. It doesn’t conduct heat very well, keeps temperatures mild 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 ideal if you are located somewhere very hot or cold.
  • Doesn’t depend on a lot of maintenance, such as painting.
  • Naturally minimizes dents and scuffs.

At Pella of Idaho, you’ll have total access to a large range of choices that suit your home’s unique design, including solid and glass fiberglass doors.

While a glass pane is an easy way to provide 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 fits with the temperatures in Idaho.

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 can’t insulate as well as fiberglass, it’s still a strong option for your front door, especially if you want additional security. Steel exterior doors are very tough, which promises considerable durability against wind and rain damage. Like fiberglass, steel doesn’t require much maintenance like painting.

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

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 Contemplate When Upgrading Your Exterior Door

Now that you’ve chosen 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 doing your door replacement project, you might be unsure of whether it’s useful to add a storm door, particularly if you previously had one. The U.S. Department of Energy says this generally isn’t worth the additional cost and won’t save you that much more energy. This combo is typically only recommended if you have an older door that’s in solid condition but requires a boost in 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 decision, as well as the weather in Idaho and your home’s specific design. This rating considers solar heat gain and U-factor.

For solar gain ratings, you’ll have the opportunity to keep your home more comfortable in the summer with lower numbers and cozy in the winter with higher numbers. Picking the ideal combination can help with better adjusting indoor temperatures.

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

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

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