Doors and windows in your home lose energy in a variety of ways
...
Conduction:
In the winter, cold air literally pulls the heat from your home. Heat
is absorbed through the window by the cold air outside. [arrow A]
Radiance:
In the summer, direct (solar) radiation pours into your home and
warms the air inside. [arrow B]
Infiltration:
In all seasons, air moves in and out of your home through tiny cracks
and crevices around your windows and doors. (A 1/16" gap around
a window amounts to a hole the size of a brick!) [arrow C]
Typically, windows
and doors have an "R-Value" of between R-1 and R-2, compared
to the rest of your home, which is typically between R-11 and R-19.
Since most building codes require approximately 25% of outside walls
to be windows and doors (for light, ventilation, and fire escape),
that means 25% of your home is not insulated the way it should be.
And it's costing you money!
