Sectional Overhead Doors
A sectional overhead door lifts in panels along a track and stows under the ceiling, which is why it suits warehouses and factories where the wall behind the opening is needed for racking or circulation. Panels can be insulated, glazed or fitted with a pedestrian leaf, and the door can be manual or motorised. The selection questions are practical ones: how often the door cycles each day, whether the opening is external or internal, how much headroom and side room the track needs, and whether the building needs the door to hold a thermal or wind performance as well as close an opening.
In this category
- Insulated Sectional Overhead DoorAn insulated sectional door for warehouse and factory openings, stowing under the ceiling on a track.
- Sectional Overhead Door with Windows and Pedestrian LeafA sectional door with a glazed section and an integrated pedestrian leaf, for bays that need sight lines and staff access.
Selection notes
- Count the daily cycles before choosing the operator; duty cycle decides the motor, not the door width.
- Check headroom and side room against the track layout at design stage, not after the wall is built.
- Insulated panels matter on climate-controlled buildings and on any door between conditioned and unconditioned space.
- If a pedestrian leaf is needed, specify it with the door so the panel reinforcement is engineered, not improvised.
Frequently asked questions
- Manual or motorised?
- Motorised operation is the norm for doors used many times a day. Manual is workable for low-cycle openings. The choice follows the cycle count.
- Can panels have windows?
- Yes. Glazed sections can be factory-fitted, with the position agreed so it does not clash with the track or the pedestrian leaf.
- What about wind load on external openings?
- External doors need the wind requirement stated at enquiry. It affects panel thickness, reinforcement and the track fixing.
- How is the door sealed?
- Perimeter sealing is specified with the door. Bottom astragal, side seals and header seals are selected together with the panel system.
