Junction function
Door jamb (side reveal) of a rolling industrial door = a detail most commonly designed in halls (each hall has at least 1 door). In a vertical panel layout, the panel terminates at the door column of the supporting structure.
Configuration:
- Steel door column (item 02) = structural element transferring loads from the building structure + door thrust (typically 200-500 kg door weight + wind pressure when open).
- Industrial door (item 03) rolling (rolling up above the opening) or sectional (segments vertically in side tracks); standard dimensions 3×3, 4×4, 5×4 m.
- GS MW panel (item 01) meets the door column with a gap left for the flashing.
- OB-21 door flashing (item 04) = multifunctional steel flashing covering the joint between the panel and the door frame.
- On-site insulation (item 05) with mineral wool in the space between the column and the panel.
Critical installation aspects
- OB-21 dedicated flashing — wider than typical cover flashings (~200-300 mm); designed specifically for door openings, accounting for the geometry of the door’s side tracks.
- OB-21 impact resistance — the door is often struck by forklifts (a typical incident in logistics halls); OB-21 is reinforced with an additional plate or bumper; do not skimp on OB-21 thickness.
- Thermal insulation (item 05) with mineral wool in the joint — critical; without insulation, a linear thermal bridge on the door column = condensation on the column in winter.
- Sealing the gap between the door and OB-21 — EPDM or neutral silicone; check every few months (failure of the gasket = rainwater leaking into the hall).
- Door column anchors to the foundation — independent of the standard hall columns; structural calculations must account for wind pressure on the open door (typically 30-50 kg/m²).
Occurs in every hall with a standard rolling door — a similar layout is used for sectional doors.
