Hangar Door Parameters

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

Opening 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, e.g., side room for sliding/stacking, headroom + inside room for raised types

Wind load resistance: Capacity to resist wind pressure, 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: 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/m²K

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 (rigid panels): 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.)

Fabric tension/weight: Pretension for tautness, density, tensile/tear strength, e.g., 2-10 N/cm pretension; 19-32 oz/yd²/900-1500 g/m² density (ASTM D751/EN ISO 1421:2017 or equiv.)

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