Make the frame 1/2" smaller than the dimensions of the window frame. The storm fits by friction and provides around R-2.3, while reducing the SHGC by a factor of 85%. These interior storms can be made for around $1 per square foot, and pay for themselves in heat savings in from 1 to 3 years (depending on climate and existing windows)
