DescriptionTop hung, flat panelled, multi leaf folding doors. Doors can have between 3 to leaves folding to one jamb (1-way), or both jambs (bi-part). Leaves hang on the back of the opening, stack clear of the reveals, and fold inwards at 90°. This steel folding door system is ideal for very wide openings, indeed unlimited widths to be exact.
The Osprey electrically operated folding door is tested for over 250,000 continuous operations. It is a simple, robust multi leaf door system which will provide many years of trouble free operation and service.
Constructed from double skinned steel panels which are either 52mm (up to 6m high) or 62mm (over 6m high) in depth with a CFC free foam filled core.
It is a top hung, flat panelled, folding door, where the door leaves can be either fully floating or hinged at one jamb, depending in the application. The leaves can hang on the inside face (back) of the opening or inbetween and fold up to 90 degrees inwards.
Just like all our folding doors the option for a wicket door in the main door leaf is a great optional feature, allowing pedestrians to access without moving any part of the main door and leaving all secured in place. This increases overall security and helps control pedestrian access, but it also helps maintain the internal atmosphere and temperature.

Panel Construction
Door panels are constructed from 1.6mm thick (52mm thick panels) or 2mm thick (62mm thick panels) cold rolled, galvanised, dovetail channel frames with spot-welded and mitred corners with L bracket stiffeners and 5mm thick local reinforcement for hardware.
The frame is covered on both sides with 0.7mm thick galvanised steel sheets and pressure injected to all corners with 50kg/m³ CFC-free polyurethane foam to form an extremely strong, rigid, flat panel.
Wicket Door (Pedestrian) Option
Standard
No Wicket door is fitted.
Option 1
Lever furniture. Wicket door opens outwards. Hardware comprises a Briton 5520 mortise sashlock, 25mm low-profile anodised aluminium lever handles, external Europrofile cylinder with internal thumbturn, 1½ pairs of stainless steel butt hinges and a hidden door limiting stay.
85mm high step with 40mm wide aluminium threshold strip.
Option 2
Emergency escape furniture. Wicket door opens outwards. Hardware comprises a Briton 379 panic bar, external override cylinder and finger latch, 1½ pairs stainless steel butt-hinges and a hidden overhead door limiting stay. 85mm high step with 40mm wide aluminium threshold strip.
Top Track and Bottom Tracking
The top track is a 5 mm thick pressed steel ‘C’ section for direct sidewall mounting. Painted in 100µ 2-pack epoxy primer. Pendant hangers are heavy-duty fabrications, each with a Ø72 mm sealed bearing wheel, two Ø40 mm side thrust sealed bearing wheels and a Ø20 mm toughened steel shaft. Each pendant is vertically adjustable. Note: Top tracks for doors above 6000mm high or electrically operated doors over 20000mm wide have an additional 8mm continuous angle reinforcement, and pendants have 25 mm shafts.
The bottom guide channel is a 3 mm thick galvanised steel pressing with built in threshold and chamfered edges. Bottom guides are Ø35 mm nylon rollers running on Ø16 mm stainless steel shafts. Ø25 mm drainage tubes are incorporated into each 3,000 mm channel section for site connection to secondary drainage.
Colour Finishes
Standard
Outside face - choice of 8 stock colours: Colorcoat® LG Plastisol in Poppy Red, Solent Blue,
Ocean Blue *, Olive Green *, Goosewing Grey, Merlin Grey * and White, or Colorcoat® Prisma in Silver Metallic. Inside face – Colorcoat® LG Plastisol in White.
All hinges and drop bolt sleeves are black polyester powder coated in RAL 9005(M)
Option 1
Outside faces of panels are polyester powder coated in a choice of 40 stock RAL colours.
Inside face in LG Plastisol in White. All hinges and drop bolt sleeves are black polyester powder coated in RAL 9005(M).
Option 2
Inside and outside faces of panels are polyester powder coated in a choice of 40 stock RAL Colours *. All hinges and drop bolt sleeves are black polyester powder coated in RAL 9005(M).
* Dark colours. It is recommended that any door panel, which is exposed to direct sun, i.e., East, South or West elevations, should be finished in a lighter colour.
The insulation properties of the panel are so good that, if darker colours are used, the surface temperature of the panel can become unbearably hot, and the outer skin
may occasionally bubble or ripple due to tiny air pockets within the panel. Taller panels may temporarily bow slightly until the temperature falls. This phenomenon is
purely aesthetic and does not affect the structural integrity of the door. For further advice on colour selection please consult the manufacturer.
Locking and Handles
Standard
Drive motor(s) automatically lock the door in the closed position. A black aluminium pull handle is fitted internally to each leading edge to enable hand operation.
Option
A lever operated floor bolt is fitted internally to each door half and is electrically interlocked
Vision Panels/Windows
Standard - None fitted.
Option 1
Black thermoplastic ‘snap-lock’ window with integral double-glazed units (2.5~15~2.5) SAN RS UV (scratch and UV resistant) outside, PMMA UV inside. Overall frame size 770mm x 430mm.
Option 2
Thermally broken aluminium window frame with one-piece inner liner tray. Window units are double glazed (4~20~4), argon filled, low E toughened glass.
Frames are polyester powder coated in matt black to RAL 9005(M), fully sealed, and available in a choice of frame sizes as follows:
400mm x 600mm, 600mm x 600mm, 400mm x 1200mm, 600mm x 1200mm.
Electric Drive System
The Osprey uses GfA electric motor systems, one of the worlds leading motor manufacturers from Germany with leading edge technology and safety.
A GfA 60Fi (up to 28 m² per motor), or GfA 140Fi (over 28m² per motor) drive motor, each with built on frequency inverter operates the door. Both have digital encoders. The motor is mounted at the end of the top track as standard, or above the track if limited sideroom, and is connected to the leading edge pendant hanger(s) via a continuous overhead drive chain. The folding action of the leaves is achieved via a built in throwout track arrangement fixed to the top track.
A TS971 digital control system featuring digital limits set from ground level, integrated wireless safety edge, variable speed programming, cycle counter and door status / fault display, two programmable relay contacts and integrated radio receiver is supplied as standard. Open /close / stop push buttons are mounted on the IP65 control panel.
Larger bi-parting doors (over 50m²) are fitted with two motors and two control panels. Each motor and control panel will operate one door half independently of the other. Please specify if simultaneous operation is required.
Drive motors are fitted with low-level haul chains for instant manual operation in the event of power failure.
Drive motors and control panels are pre-wired with a 3m, 5m or 7m SWA cable, and fitted with a 5-pin euro-socket to plug directly into a 5-pin socket
Access Control Logic
Standard
Deadman - continuous push to open, continuous push to close. This logic must be used unless a Safety Edge and Opening Safety Sensors are installed.
Option 1
Semi-automatic - Single push to open, Single push to close. Stop button stops door. *
Option 2
Automatic – Single push to open, automatic closing after pre-set pause time (between 1 – 240 seconds). Stop button stops, and holds doors. *
*Note: Control logic. In accordance with BS EN 12453:2001, a minimum of a safety edge and opening safety sensors must be installed for semi-automatic (Option 1)
or automatic closing (Option 2).
Safety Features
Safety Edges (with Control Logic Option 1 & 2) A full height wireless opto-electronic safety edge is mounted within the leading edge seal(s) of the door. An impact on the edge during closing will automatically stop and re-open the door.
The safety edge is continuously monitored so the door cannot close automatically in the event of damage or failure of the edge. A low-battery warning audible alarm will advise when the battery needs to be replaced.
Opening Safety Sensors (with Control Logic Option 1 & 2)
Infrared presence detection sensors are fitted to the inside face of the trailing edge leaf to each door half to prevent the door impacting / crushing a person or object during movement. Active infrared detectors are fitted externally above the opening at each side of the door, and internally at high level on the inside of the door’s bunching area to prevent the door impacting / crushing a person or object during movement. In the event of any detection during door movement, that door half will stop.
