To help remodelers lessen finishing time and reduce labor costs, Andersen Windows offers prefinished white interiors in its Andersen Frenchwood inswing and Frenchwood gliding patio doors. Patio doors come with tempered, low-e glazing. Frenchwood patio doors may be ordered with either High-Performance glass for all-season climates or High-Performance Sun glass for desert and tropical climates. Additionally, Frenchwood door panels lock at the top and bottom with a hardened steel hook-bolt system. A dead-bolt locks the door in the middle. The system provides weather resistance and security.
