The Ascot overhead sectional door is an insulated sectional door which opens vertically. The door can follow the vertical wall or turn horizontally to follow the ceiling or roof pitch, with a track system selected to suit your building.
The torsion spring assembly mounted above the lintel balances the door making it suitable for manual operation by pull rope or hand chain, or by electrical operation. The 40mm thick door panels are constructed from galvanised steel sheets bonded together with high density CFC free polyurethane foam with a thermal break at each joint. Thermal ‘U’ values are:
Individual solid panels 0.6W/m²k
Full solid door 0.9W/m²k
Full door with windows OR pass door 1.0W/m²k
Full door with windows AND pass door 1.1W/m²k
Vertical and horizontal tracks, hinges, brackets, side capping and hardware are galvanised, with the assembled door running on adjustable galvanised roller carriers bolted to each individual panel. Operation is either manual spring loaded with key lock or electric.
