We often get questions from homeowners asking what type of door is most energy efficient. There are a lot of factors that go into determining energy efficiency, but the first question you should ask yourself is not about the door itself, but about your home’s construction.
The first step in selecting an energy-efficient door is to take a look at your home’s windows, walls and other doors. If your front door is flanked by large picture windows or if you have limited insulation in your walls, then adding a new insulated door could be a great way to save on utility bills. On the other hand, if your home has plenty of insulation and there aren’t any major drafts coming through the existing windows and doors, an insulated door will do little to improve its overall energy efficiency.
The best way to determine whether or not your home could benefit from an insulated front entry door is by doing what’s known as a blower test. This test involves sealing all the windows and doors of your home to see how much air escapes when a powerful fan is applied at various points around the house. A professional can also perform this test for you, although it can be fun and educational for the whole family.
Most Energy-efficient Doors
An energy efficient front door will help you save money and be more comfortable. But what type of door is most energy efficient? The truth is that any exterior door will work to block drafts and save you money. It’s the quality of the installation that really matters. But there are some doors that will work better than others.
Let’s start with a rundown of the different types of energy efficient doors:
1. Fiberglass Doors
These doors are highly energy efficient, as they are very good at resisting heat transfer in both directions. They are also durable and relatively maintenance free.
2. Steel Doors
Steel is a popular choice for front entry doors because it’s durable and affordable. But steel is also an excellent insulator, which makes steel doors energy efficient choices for your home. Steel doors are available in a variety of sizes and styles to suit most homeowners’ needs, and they’re usually painted when purchased so they don’t require painting after installation.
Of course, steel doors are not as energy efficient as fiberglass, but they tend to cost less so they can fit into your budget if you’re not looking for top-of-the-line efficiency. And if you accessorize them with foam insulation, weather stripping, and other accessories, steel doors can perform quite well.
3. Wooden Doors
Wood is a natural insulator and great at blocking heat transfer from inside out or outside in. Wooden doors come in many styles and have a timeless look about them, though they will require regular maintenance to keep their looks up to par and their durability.
4. Vinyl Doors
Vinyl doors are among the most energy efficient on the market today. These materials are strong and durable, so they will not warp or crack over time. They comprise a heavy-duty frame that can withstand extreme weather conditions and still keep heat inside the home where it belongs.
