If you have the sizes, we can give you an instant price on your project.

We price the Innerglass Window by the United Inch. The formula is Width + Height = U.I.

We calculate the price of a 30” by 50” compression window in Low E glass as follows:

30 + 50 = 80 United Inches x $3.25 = $260
11 square feet in clear glass x $3 = $33 + $260 = $293 Total
11 square feed in Low E glass x $6 = $66 + $260 = $326.00 Total
