System and operation
Fixed, projected, hung, storefront, curtain wall and window wall use different frames, hardware, fabrication and testing paths.

Insulating, tempered, laminated, spandrel, privacy, frit and acoustic glass change cost and availability. Anodized and painted finishes have different minimums and lead times.
