The Window Specialist most frequently asked question:

How to best realize savings on utility bills with new window installation or replacement?


Good quality windows, installed properly can yield substantial energy savings. The amount of savings depends on the type of window chosen and the type and condition of the windows being replaced.

In the average home, 38% of the heat loss is through the windows and doors. Heat loss from drafty, single-pane windows or aluminum sliders may be as much as 50%. The poorer the performance of your current windows, the more dramatic the savings. Is LowE3 better than LowE2?  Not necessarily.
