Barrier Fold bi-folding cooler/freezer door combines a highly efficient sealing system with impact resistance, high speed, and a small footprint. In addition to creating a tight, conforming seal, the air seal system also broadcasts warm air across door and surrounding floor area to prevent frost and to reduce maintenance and operating costs. Door is reportedly 42% more efficient than PVC fast doors. Rite-Hite Doors, Inc., Milwaukee, WI
