Bay & Bow Windows

Viviano hand crafts every dimensional projection window to your specifications utilizing only the very finest raw materials. The frames of the window, as well as the head and seat boards, are constructed using the most high-end furniture-grade oak or birch plywood available.

The mullion posts between the windows of the unit are not only structural, but they are also completely filled with energy efficient, die-cut polystyrene foam. The head and seat boards are tied together as one, using steel through-rods, making the unit incredibly strong and weathertight.

Our warranty fully covers defects and parts failure for the life of the product. Any and all service issues are personally handled by a member of our staff to your complete satisfaction.
