Abstract: A retractable dual screen system provides auxiliary environmental protection for garage door openings. An upper housing is mounted on an exterior of a garage door, including two rollers and is accessible for maintenance or repair by a removable cover. A first roller is a vinyl insect screening, and a second roller contains polyolefin material to provide an additional layer of insulation to help reduce heat loss and gain through the garage door. The second roller also provides a vapor barrier to help protect the garage door against high winds. A dual track system selectively allows both rollers to be independently deployed over the garage door opening.
