Insulation & air sealing

 Insulation & air sealing

The U.S. Department of Energy recommends an R-49 insulation rating in the attic because Colorado is considered a northern, cold climate state.

Insulating and sealing 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, keeping it cooler in summer and warmer in winter. ENERGY STAR® estimates that a knowledgeable homeowner or skilled contractor can save up to 20% on heating and cooling costs (or up to 10% on their total annual energy bill) by insulating and sealing.

  • 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
