Calculate the Total Cost of a Door, Including Energy Losses
Choose the city closest to your location, and the calculator will automatically apply the local annual average temperature and wind conditions. Enter your indoor temperature and fill in the specifications for your door and a competing door. When you''re done, click the button at the bottom to compare total costs.
Note: Do not use the "best average" U-value, since it only reflects the most insulated part of the door panel. Instead, use the total U-value, which accounts for windows, pedestrian doors, and seals.
