Hangar Door Parameters

Clear opening width: Total clear width for aircraft entry with maneuvering clearance, e.g., wingspan + 3-6 ft/1-2 m

Height: Vertical clearance including safety buffer above tallest aircraft, e.g., tail height + 3-6 ft/1-2 m

Interior clearances: Space required for door operation (side room for sliding/stacking, headroom for bi-fold/lift)

Wind load resistance: Capacity to resist wind pressures, e.g., 20 psf/1 kPa min to 100+ psf/4.8+ kPa (ASTM E330/ASCE 7, EN 12219 or equiv.)

Fire rating: Resistance to fire spread through door, e.g., 60-180 minutes (UL 10B/IBC, EN 1634 or equiv.)

R-value (insulation): Thermal resistance of insulation material, e.g., R-10/RSI 1.8 min to R-32/RSI 5.6 (ASHRAE 90.1, EN 12428 or equiv.)

U-value (heat loss): Overall heat transfer of total door assembly, averaged to square meter, e.g., ≤0.6 W/m²·K

Opening speeds: Operating velocity range for safe/efficient travel, e.g., 0.5-1.6 ft/s/0.16-0.5 m/s

Deflection limit (bottom rolling): Maximum panel flex without binding/seal failure, e.g., L/120 span, 1 ft/305 mm max on 120 ft leaf (AISC 360/IBC, EN 1993 or equiv.)

Dead load (fabric): Full door weight transfers to header beams via tension cables/tracks, e.g. 100 lb/ft width (NFBA/ASCE 7-22, EN 15275 or equiv.)

Fabric tension/weight: Tensile/tear strength and fabric thickness, e.g., 900-1500 g/m²/19-32 oz/yd² (EN ISO 1421:2017, DIN 53354 or equiv.)

Drive systems: Drive mechanism and control specifications, e.g., motors, warning systems, control panels
