How Doors Can Affect Energy Efficiency in Your Home

May 13, 2022

You are not asking for too much!

Energy efficiency is essential, and every homeowner should worry about the amount of energy they use in their home. Of course, you want your home to be comfortable. After all, it is your haven, your place of peace and relaxation. But that does not mean you shouldn’t worry about your home being as energy efficient as possible. You don’t want to be spending a ton of money to heat and cool your home.

So now that you’ve taken a good long look at those old doors, you can see that they are not doing their jobright off the bat. They are not energy efficient. Look at those cracks. You can see through them. Nope, not good at all! Those old doors are zapping your energy and making you spend more on electricity, which is why finding the right energy-efficient doors.

The R Values and Why They are Important

At some point in time, you need to update those doors, both because you need higher efficiency, and it may just be time to get a new updated look for your home. But where do you start?

First things first, you need to pay attention to R-values when shopping for doors. The R-values tell you more about the door. They speak of the quality and, more importantly, of the energy efficiency level. In technical terms, the R-level denotes the door’s thermal reflection ability. The door with a higher R-value has more insulation properties, is temperature regulated, and has better soundproof qualities. And those are the primary features you want in a door, right?

Most standard doors have an average R-value of 3 to 5, with 3 being the lowest. Something you probably don’t want. On the other hand, a value of 5 is much better but still not optimal. If energy efficiency is high on your list of priorities, and it should be, then you want triple glazed doors or insulation levels with R levels that range from 5 to 9.

What is the U-value?

Another feature you must consider when buying a new door for your home is the U-value. No! Unfortunately, it's not an immediate rebate for the door, but it does offer you future savings. The U-value is the rate at which heat transfers through the door. So if the U-value is lower, the more energy-efficient it is.

Standard doors have a U-value of .65, whereas true energy-efficient doors have a U-value of .09. That's worth looking at, especially over the long run, because it can save you quite a bit of cash.

It’s A Great Investment

Replacing your doors is not like buying a $2000 pair of shoes. Your door is a part of your haven, your sanctuary. It is much more important. It is a valuable investment, and it will save you money on those high electricity bills.


Energy-efficient doors help control the interior temperature and the humidity in your home. In addition, they are safer for the environment and help reduce energy consumption. It is cost-effective to replace those old doors. So your best idea is to find a reliable door company to replace that old door.
