Air Seal With Foam InsulationCan you see light making it’s way past your front or back door?    Take a close look all around the edges. If you can see light, then you have found a air leak. It might be time to air seal the door with self adhering foam weatherstripping.

The exterior doors have a huge job to do.

1.  Let people and pets in and out of the home.

2.  Plug one of the biggest holes in your home, the door opening.

3.  Separate the outdoor climate from the indoor climate helping to keep your home both efficiently warm and cool.

Take a moment and count the number of times your favorite door opens and closes during a day. Between the kids, pets, and working in the yard after work, the door may open and close a hundred times.

The weatherstripping is a little like the soles on your shoes, going to wear out sooner or later. The more steps you take, the sooner you need a new pair of shoes.

The video below is one that I recommend for learning how to install new weatherstripping on a door. If you can do-it-yourself, this video is for you. By the time you weatherstrip the front door, the back door, and the door into the garage, you’re in a position to see some real energy savings.

Ever wonder where that unidentified draft was coming from? You can feel it, but it is so slight it is hard to determine where it’s coming from. You might want to give your exterior doors the sunlight test. If you can see light coming through you know air is sure to follow.
