Effective Jan. 1, 2016, we will be using the current U.S. Department of Energy recommendations for attic insulation instead of the 2009 IECC recommended values. Because Colorado is considered a northern, cold climate, the Department of Energy recommends an R-49 insulation rating in the attic.
Did you know?
Sealing and insulating the "envelope" or "shell" of your home — its outer walls, ceiling, windows, doors, and floors — is often the most cost effective way to improve energy efficiency and comfort. ENERGY STAR® estimates that a knowledgeable homeowner or skilled contractor can save up to 20 percent on heating and cooling costs (or up to 10 percent on their total annual energy bill) by sealing and insulating.
- Seal air leaks throughout the home to stop drafts
- Add insulation to block heat loss in winter and heat gain in summer
- If one of the leaks is through inefficient windows, replace them with ENERGY STAR qualified windows
