Insulated Sectional Overhead Doors
Door panels formed from galvanised steel sheets bonded together with high density C.F.C. FREE polyurethane foam to provide a ‘U’ value of 0.44 W/m²K with a thermal break between panels. Vertical and horizontal tracks, hinges, brackets, cappings and hardware are galvanised, with the assembled door running on adjustable galvanised roller carriers, bolted to each individual panel. Each door is counterbalanced by means of tempered helical springs at high level, mounted on bright steel plates with self-aligning roller bearings for smooth quiet operation. Cable tensioning devices are fitted as standard to all doors. Rubber seals are fitted to the top and bottom of each door with P.V.C. seals to each side of the opening for protection against weather.
Manual operation by means of continuous galvanised hand chain or ‘push up’ with pull down cord. Electric operation by means of 415 volts 3 phase supply drive motor with emergency disconnection and hand chain or push up operation in the event of power failure.
Standard external finish on door panel is white polyester primer. Standard internal finish on door panel is stipple white polyester primer. All manually operated doors are fitted with a recessed lifting handle and spring-loaded shoot bolt as standard.
