18x14 fiberglass mesh WORKS FOR MOST EXISTING GARAGE DOORS: Lifestyle Screens work with most existing garage doors. Unfortunately, Lifestyle Screens DO NOT work with low headroom garage door tracks. From the inside, please measure your actual garage door (NOT your garage opening) twice before ordering your Lifestyle Screen. GET MORE OUT OF YOUR GARAGE: The Lifestyle Screen allows you to easily transform your garage into a versatile living space. The Lifestyle Screen is a perfect choice for someone looking to convert their garage into much more than a parking space for your car in ways such as a man cave, exercise room, a recreation room, kids and pet’s room, hobby area, and much more! WORKS ALONGSIDE YOUR PERMANENT GARAGE DOOR: The fully retractable, spring loaded system of the Lifestyle Screens allows the unit to work independently from your permanent garage door tracking system in order to ventilate or brighten your garage in seconds. When in use, the Lifestyle Screen occupies the same position as your permanent garage door. When not in use, the Lifestyle is in a horizontal position and positioned directly under your permanent garage door. EASY TO USE: The spring-loaded, counterbalance system and the practical design of the Lifestyle allows for the lowering and raising of the Lifestyle Screen with ease. Lifestyle Screens comes standard with an industry-first retractable center door to allow for easy entry and exit. There are also Lifestyle Screens available without the center passage door. DURABLE MATERIALS: The Lifestyle's frame is composed of architectural grade, 2"x2", 050 gauge aluminum with a powder coated finish. You have three different screen fabric choices: the 18 x14 standard charcoal fiberglass mesh that allows for maximum airflow, two upgraded 17 x 20 PVC Coated Polyester options which allow for improved durability, privacy and pet resistance. Finally, choose from three different frame colors and a variety of standard sizes (custom sizes are also available).
