The Barrier Glider from Rite-Hite is a thermal air-sealing, impactable, high-speed, cold-storage door. The Thermal-Air sealing system inflates to a 6-in. diameter, conforming fabric ducts to seal the perimeter of the bi-parting doors and creates a pressurized energy-saving seal. The ducts bathe the surrounding floor, door and mechanisms with air movement to prevent maintenance intensive ice build-ups. It uses flexible, insulated panels, that when combined with its tubular track and hourglass roller mechanical design, withstand common industrial impacts without bending or seal damage.
