Straight answers

Buying low-e pass-through windows

Can I enter a nonstandard width and height?

Yes. Any positive dimensions can enter project review, including fractional sizes. The exact sash, panel, glass, hardware and fabrication limits are verified before a price or production size is approved.

Why is the final price not calculated from square footage?

Operation, sash or panel weight, glass, frame, sill, screen, controls, hardware, crate and freight can change independently of area. The quote uses a verified product configuration rather than an unsupported area formula.
