Insulated Sectional Overhead Doors

DP Doors & Shutters high specification Sectional Overhead Doors are designed for large external openings to give unobstructed access and low maintenance, trouble free, weather proof service. A choice of widths and heights is available, as every door is made to customer’s individual requirements, and can cater for low headroom, high lift, contour (following the roof line) and vertical lift situations.

Construction is of materials specially selected to withstand the rigours of daily use, making them ideal for high traffic areas. Door panels are constructed from galvanised steel sheet bonded with high density CFC free polyurethane foam, producing a strong rigid section with excellent ‘U’ value and a thermal break between panels. All associated hardware is of galvanised steel and seals at the top and bottom and at each side ensure weather protection.

Each door is counterbalanced by tempered helical springs mounted at high level on roller bearings for quiet, smooth operation, with cable tensioning devices. Operation can be manual via continuous chain or push up with pull down cord, or electrical via appropriate single or 3 phase motor with push button control and emergency cut-off with hand operation facility. Automatic activation can be by all types of electronic control mechanisms and safety edges can be supplied. Options include external locking, pass door and double glazed windows.
