The Hormann ALR F42 and ALR F42 Thermo industrial sectional door has Duratec synthetic glazing and offers excellent transparency and good thermal insulation thanks to the glazing profiles and thermal break.
The bottom door section is delivered with PU infill and aluminium sheet cover, both sides Stucco-textured as standard. Optionally, the door is available fully glazed without surcharge.

Superior Thermal Performance with Full Aluminium Construction
High-Performance Thermal Specifications
The ALR F42 Thermo achieves impressive thermal insulation values, with U-values as low as 1.6 W/(m²·K) for a standard 5000 x 5000mm door size. This exceptional thermal efficiency makes the door suitable for applications where temperature control is critical, including food processing facilities, pharmaceutical manufacturing, cold storage warehouses, and logistics centres handling temperature-sensitive goods.
All-Aluminium Construction Benefits
Full aluminium construction delivers numerous practical advantages for industrial applications. Aluminium's natural corrosion resistance eliminates rust concerns, making these doors ideal for coastal locations, chemical processing environments, and facilities exposed to moisture or aggressive atmospheric conditions. The lightweight properties of aluminium enable smoother operation with reduced stress on operators and hardware components, extending service life and reducing maintenance requirements.
Substantial Opening Capabilities
The ALR F42 Thermo accommodates exceptionally large opening dimensions, with maximum width capacity of 8000mm and maximum height of 7500mm. These substantial dimensions make the door suitable for large-format industrial applications including aircraft hangars, ship repair facilities, manufacturing plants, and logistics distribution centres requiring oversized vehicle access.
Advanced Glazing Options
For applications requiring vision panels or natural light transmission, the ALR F42 Thermo can incorporate glazed sections with thermal break glazing beads. These maintain the door's enhanced thermal performance whilst providing visibility and daylight benefits. Double-glazed or triple-glazed units can be specified to match overall door thermal performance requirements.
Robust Weather Protection
The door achieves excellent weather resistance performance, including Class 3 wind load resistance for stability in exposed locations, Class 3 watertightness (70 Pa) for effective rain exclusion, and Class 2 air permeability for minimal air infiltration. All-round perimeter sealing on four sides, combined with intermediate seals between door sections, creates comprehensive weather protection.
Durable Surface Finishes
Standard anodised E6/C0 finish provides excellent corrosion resistance and a contemporary metallic appearance. RAL powder coating options enable colour-matched specification to complement corporate branding or architectural requirements, with a comprehensive colour palette available.
