Special shape windows: the ultimate in custom

Special shape windows can distinguish your home. If you own a custom-designed house with special windows that need replacing, most major window manufacturers like Marvin, Pella, Simonton and Milgard make shapes that fit snug and sound. Common and uncommon shapes include the circle, octagon, elliptical, quarter-round, eyebrow, trapezoid, pentoid, partial or half chord, and triangle. Within most large shapes, you can also order multiple, divided lites in smaller shapes that complement the overall window. Materials include wood--maple, oak and cherry--as well as vinyl- or aluminum-clad frames. In-sash windows can be made to match daylight openings in your existing doors and windows.

Other options include grids to match architectural styles like prairie or colonial. Manufacturers allow you to choose from factory-assembled window combinations that offer a custom-like appearance at a lower cost. Low-e coatings and insulating glass round out a wealth of special window options.
