The Hormann APU F42 Thermo is the effectively insulated and highly stable door that allows large volumes of light through. With windows created from Duratec maximum scratch resistant glass, your windows will stay clean and scratch free wash after wash.
If you seek full use of daylight, good thermal insulation and a high level of stability are called for then the Hormann APU F42 Thermo door can meet these requirements threefold; on account of the cold-repelling 16mm thick double glazing, the aluminium extrusions with thermal breaks and the PU foam-insulated steel bottom section. This is 100% CFC-free. This combination produces a remarkable thermal insulation value.
The aluminium extrusion has an overall thickness of 42mm. The outer and inner shells incorporate thermal breaks with glass fibra reinforced polyamide ribs and are at the same time positively bonded. This ensures a high degree of stability and protects the structural fabric.
The 750mm high bottom section in steel: white aluminium (based on RAL 9006). The glazing frames in aluminium: anodized to DIN 17611 stained in a natural colour (E6/EV1). Optionally available in Stucco or Micrograin surface finish without a surcharge.

Enhanced Thermal Glazed Door for Energy-Conscious Facilities
Hybrid Construction with Thermal Enhancement
Balanced Performance for Commercial Applications
The APU F42 Thermo strikes an effective balance between visibility, natural light transmission, and thermal efficiency, making it ideal for:
Substantial Opening Dimensions
Improved Thermal Specifications
The thermal break technology delivers measurably improved U-values compared to standard APU F42 Vision specification. The enhanced thermal performance reduces heating and cooling costs, making the door suitable for climate-controlled facilities where energy efficiency impacts operational budgets. The precise thermal improvement depends on glazing specification and overall door configuration.
Glazing and Frame Options
The aluminium frames accommodate double-glazed or optionally triple-glazed units, with thermal break glazing beads maintaining improved thermal performance throughout the glazing system. The narrow-profile frames maximise glazed area whilst securely retaining glass units and maintaining weather sealing.
Robust Steel Bottom Section
Wicket Door Integration
Integrated wicket door option provides convenient pedestrian access with 940mm clear passage width. The wicket door maintains thermal efficiency whilst enabling personnel movement without full door operation, reducing energy losses and improving operational efficiency in facilities with frequent foot traffic.
Weather Protection and Sealing
Comprehensive weather sealing includes all-round perimeter sealing on four sides plus intermediate seals between door sections. The door achieves Class 3 wind load resistance (120 km/h) and Class 3 watertightness (70 Pa), providing robust weather protection despite extensive glazing. Class 2 air permeability minimises infiltration losses.
Surface Finishes
Electric Operation
Safety Systems
Energy Efficiency Considerations
The enhanced thermal performance delivers operational cost savings in climate-controlled facilities. Reduced heating or cooling losses through the door translate directly to lower energy consumption. The natural light benefits additionally reduce artificial lighting requirements, further improving overall building energy efficiency.
