In this video, we learn how to insulate an attic pull down with Roy Honican. Doing this can help keep your home warmer and more energy efficient. First, measure around the top of the attic so you can build a box that will stand on top of it. To build the box, use foam board that is 1" thick. Cut the size to the sizes you just measured. After this, use foam tape to tape all the pieces together. Once you're done with this, you will have a large box and you will be ready to go back upstairs. Place weather stripping underneath where the box will go above the pull down stairs, then drop the box down and you're finished!
