New means better and more efficient investment so is the new window changing. Age and temperature change the window by causing the frames and panes to expand and contract causing gaps in the seal that means less insulation for your home.

Insulating your house better means changing your windows and a double pane window does it better. It is even an economic investment by affecting your heating and cooling bills. Double pane windows are windows with two panes of glass glazed to the movable part of the window. This window is designed specifically to insulate your home.
