Avoid Common aluminum framing patio doors

Aluminum is strong, durable, non-corrosive; but aluminum is also a highly conductive material. It conducts more heat than any other construction material, which makes aluminum frames a bad choice - unless the frames are designed with built-in insulation elements. Consider other types of frames for your patio doors, namely fiberglass and high-quality PVC.

Protect as much as possible your patio doors. Use awnings, shutters, blinds, and other similar sun-screening devices. Consider the shade of trees, and pergolas… Use draperies to minimize heat loss in the winter. Consider also wind-breaks.
