Q-Door QF4 Manually operated folding door

SIZE & PANEL DIVISION

To ensure the best insulation and minimal air leakage, each door is precisely adapted to your specific opening.

• Width: 2,4 m – 7 m
• Height: up to 6 m
• Panel thickness: 56 mm
• Panel material: 0.6 mm SSAB Greencoat® steel with C5 corrosion class and bio-based coating. The sheet is bent for maximum rigidity.
• Core: High-density polyurethane foam, chemically bonded to all components. Each cubic centimetre contains tens of thousands of gas-filled cells that block heat and cold transfer.
• Panel configurations: 0+4, 1+3, 2+2, 3+1, 4+0
• Wicket door: Minimum threshold height 130 mm. Maximum door width = section width minus 340 mm. Available for SK2 and SK3.
• Windows: Gas-insulated, with thermal breaks.
  • Max total window area (motorised): 43% of panel surface
  • Max window width = section width minus 300 mm
  • Min spacing between rows: 200 mm
  • SK2 models can include windows; SK3 cannot.

PERFORMANCE

• Expected service life: 30 years
• Wind load resistance: Class 5
• Water tightness: Class 2 or 3 (depending on configuration)
• Opening speed: ~0.25 m/s (depends on door width)

PANEL STRUCTURE

The door consists of four panels and can be configured with 0, 2, or 4 panels on either side:

• 0+4
• 1+3
• 2+2
• 3+1
• 4+0

SURFACE, CORROSION PROTECTION & INSULATION

Each 56 mm panel is clad with SSAB Greencoat® 0.6 mm steel, C5 corrosion class, and bio-based coating. The bent sheet provides torsional stiffness, and the panel core of high-density foam offers excellent insulation.

• Best U-value (individual panel): ~0.22 W/m²K
• U-value (example 5x5 m door): 0.90 W/m²K
• T-value (example):
  • Motorised: 0.9 m³/h per m²
  • Manual: 1.5 m³/h per m²

If you want another color we can coat your door with any of the 10 million colors in the NCS- and RAL-systems.
