Best Energy Efficient Exterior Doors

November 14, 2023

The goal of replacing your home elements like the electronics, doors, windows, roof, etc. is to lower down the amounts of energy consumed by them. The ultimate aim is to get the least utility bills. Each element of your house can significantly contribute in this.

A good insulating door keeps the outdoor weather out of your house and prevents unwanted heat exchange. It also prevents air and temperature leak from the house. This means that the amount of energy used to heat or cool your house internally is not wasted if you have energy efficient doors. The best energy efficient doors act as a seal between the temperatures inside and outside the house. Let's look at some of the best energy efficient doors that are also great in aesthetics.

Fiberglass Exterior Doors

Fiberglass is a poor conductor of heat and electricity. Due to this property, fiberglass doors offer up to almost four times the insulating R-value of the wooden doors. These doors are highly weather resistant which means the rate of heat loss will be minimal.

Vinyl Doors

Vinyl is another energy efficient door material. Vinyl door provides good thermal insulation which blocks external heat or cold air to enter the house. Also, it retains the temperature inside the house. These low maintenance doors are also available in vinyl-cladded wooden options.

Steel Doors

Steel doors are also energy efficient as steel is a good thermal insulator. The only drawback is that it is a good conductor of heat, which means you can feel the coldness or hotness when touching this door.

Wooden Doors

Widely and commonly used wooden doors are poor insulators of heat. They are the least energy efficient doors out of all the materials. They absorb the heat and even cause heat flow.

Most of these doors have a core filled with polyurethane foam that adds to the energy efficiency factor.

Glass and Weatherstripping

If you want your exterior door with glass panes, there are energy efficient options available for the glass too. Glass with a higher low-E coating are energy efficient as they reflect most of the heat outside. Another energy efficiency solution is weatherstripping. Weatherstripping is the application of insulating strip around the door perimeter to avoid air and heat flow. Weatherstripping ensures that absolutely no heat is exchanged and adds an additional barrier to the flow.

Always look for Energy Star rated doors and glass panes for your exterior doors. You can select the material and style on your own, but don't try to install the door by yourself.
