A significant cause of energy loss is due to air leakage from windows. Air leakage from windows can
reduce indoor comfort. Energy Efficient windows have a greater ability to prevent air leakage, or energy
loss.
The window industry quantifies a windows ability to prevent energy loss by a measure called the U-Factor. Windows with a low U-Factor are most energy efficient, the lower the U-Factor the lower the
chance of energy loss.
Low U-Factor windows provide benefits for all climates; they help retain heat in colder climates and
reduce solar heat gain in warmer climates, directly reducing your energy loss. A reduction in energy loss
will reduce your energy consumption which will reduce your energy cost. |
