Much like windows, exterior doors play a large role in energy efficiency and “curb appeal” for your home. It is important to make sure your doors are air-tight and properly installed to insure the least amount of energy and money is wasted. Replacing older doors in the home may reduce heating and cooling bills by as much as 10%, resulting in your home to become more energy and cost-efficient.
There are a variety of different materials that exterior door replacements can be made out of, but these are the most common:
Steel doors add security and are energy efficient. They are easy to install and look good in appearance. A steel door’s lifespan is between 5 and 7 years and is durable, but may not last for a long period of time if your home is located in severe weather or associated with heavy usage.
If you are looking to boost your “curb appeal” substantially, a wood door may be the way to go. However, these doors require a lot of maintenance, and you must paint the door annually to prevent damage.
It is important to realize the materials a door is made out of is only one of the criteria involved with efficiency. The Energy Star associated with every door should help you understand how energy and cost-efficient the door will be.
