insulation losses
  • Insulating your home and ductwork is an inexpensive and easy project to do, so go for it.

    While we are on the subject:
    In the average home:
    35% of heat is lost through the gaps around doors and windows.
    18% directly through the doors and windows themselves!
    (a door or window cannot hold in the heat as well as an insulated wall)
    17% through the floor into the unheated basement or crawlspace.
    13% through poorly insulated walls.
    10% through the ceiling into the attic.

    That leaves only 8% to keep you warm!
