Cutting your utility bill: Simple, low-cost door improvements can save energy, improve comfort
from Reading Eagle
People often do not realize how leaky an old door has become. Chairs and sofas are typically not very close to a door, so drafts are not noticed. Check doors for leaks by moving a stick of lighted incense around the edge on a windy day. Observe the smoke trail for signs of leaky spots. If you are having a problem finding the leaky spots by watching the smoke trail from incense, have a helper shine a flashlight in around the edge at night and look for light coming through. Leaky spots also allow more road noise to come through, so listen for the noisiest spots around the edge.
