Try This: Build Your Own Interior Shutters

Try interior shutters instead of draperies to add to the R-value and to the character of your home.

Measure your window frame opening carefully. Remember, the shutters will be framed in wood trim, so include the thickness of the trim when calculating the size of the foam board. Measure, score and cut the fibrous paper facing on both sides of the foam board with a utility knife. Then the board can be snapped cleanly with a good karate chop. Be sure to protect your hands with gloves.
