Cathedral ceilings can add charm and beauty to a house, but they may not be energy efficient. However, there are ways to build an energy efficient cathedral ceiling so that you can enjoy the aesthetic of the structure without increasing your utility bills.
Instructions
1. Use deep ceiling joists to allow for thicker insulation. If you're going to be using 10-in. insulation, build the cathedral ceiling with 12- to 16-inch ceiling joists.
2. Place a radiant barrier in the cathedral ceiling. An aluminum foil radiant barrier, installed with the foil side facing the sun, blocks heat transfer and make your cathedral ceiling more energy efficient.
3. Install a ceiling fan with a reverse switch in your cathedral ceiling. This helps distribute warm air in the winter and draw cooler air up in the summer, keeping room temperatures balanced.
4. Avoid recessed lighting in a cathedral ceiling, as heat can escape from around such fixtures. It is recommended to use track lighting when you have a cathedral ceiling. If recessed lighting must be used, make sure they are airtight and IC (Insulation Contact) rated to make your cathedral ceiling more energy efficient.
5. Caulk around any electrical boxes or heating of air conditioning vents in the cathedral ceiling, or use foam gaskets. Caulk holes in ceiling joists where wires are run through.
