The highly customizable 1500 Vinyl Collection makes it easier to specify PlyGem windows by consolidating a number of different vinyl window lines into one platform. Builders start with the window type (single-hung, sliding, picture, or architectural shapes) then choose from various frames (brickmold, beveled, or flat), colors, grilles, hardware options, and energy features. Prices vary widely; the unit shown would cost between $185 and $200.
