Having trouble staying warm during this northwest winter? Below are reasons why your inefficient old windows could be the source!
- Over 50% of heat loss in a typical house occurs through the windows and doors.
- Heat conducted through glass and frames can lose the equivalent of a pint of oil every day for each window.
- Air infiltration due to a crack 1/16th inch wide in an average window frame is the equivalent of having a hole in your wall the size of a brick. In an average house this is like having a hole the size of 15 bricks.
