A patio cover can help make your deck or patio more inviting and comfortable when entertaining, grilling out, or just relaxing outside. Unlike a retractable awning that only provides sun protection, a patio canopy is designed with an aluminum frame and will provide protection for your outdoor space not only from full sun, but also during rainy or windy weather, making your deck or patio more useable. Side panels or curtains can provide extra protection from unseasonable weather and extend your outdoor season.
