The Hormann ALR F42 is an aluminium industrial sectional door designed and ready for on-site cladding by others, with either timber, metal or many other suitable exterior building materials. The facade cladding door base consists of frame profiles with PU sandwich infill. The horizontal profiles are cladded.
You can design the on-site, flush fitting facade cladding according to your design with either timber, metal, ceramic or plastic.
Please Note: There is a maximum weight per door unit depending on size and mechanism specification, please ask for further details.
Many modern buildings require bespoke door designs and require doors which blend in completely with their facade. This door is perfect for just such applications, offering all the benefits of a sectional door mechanism and the vertical movement for minimal disruption at ground level insude and outside the entrance. Manual or electric operation with a whole range of access controls for the perfect management and security of the door.

Unlimited Architectural Expression with On-Site Cladding
The Hormann ALR F42 "Create Your Own Design" represents a revolutionary approach to industrial sectional door specification, enabling architects and building designers to achieve virtually any exterior aesthetic whilst maintaining the proven engineering excellence of Hormann's industrial door mechanisms. This innovative system provides an aluminium framework sectional door ready for on-site cladding with materials of your choice, delivering unmatched design flexibility for prestigious commercial developments, architectural showpieces, and corporate facilities requiring distinctive visual identity.
The ALR F42 framework accepts exterior cladding materials including timber, metal panels, ceramic tiles, composite materials, plastic sheets, and numerous other architectural finishes up to 46mm thickness. This extraordinary versatility enables the door facade to seamlessly integrate with surrounding building materials, creating visual continuity that makes the door almost invisible within the overall architectural composition.
Professional Framework System
The underlying ALR F42 mechanism utilises robust 42mm-deep aluminium sections providing the structural framework and operational mechanisms, whilst the exterior face remains ready for your specified cladding application. The lightweight yet strong aluminium framework ensures smooth operation despite the additional weight of external cladding materials, with industrial-grade hardware components sized to accommodate the combined mass.
The framework's maximum load-bearing capacity accommodates substantial cladding materials, enabling specification of premium timber species, heavy metal panels, or thick composite materials without compromising operational performance. Professional installation guidance ensures proper cladding attachment methods that maintain door flexibility whilst securely retaining facade materials.
Design Freedom and Material Choice
The cladding possibilities are virtually limitless. Timber cladding enables beautiful natural wood aesthetics matching surrounding building timber work, with options from Western Red Cedar to tropical hardwoods. Metal cladding can replicate adjacent architectural metal panels in copper, aluminium composite, steel, or zinc. Ceramic tiles or panels provide Mediterranean or contemporary aesthetics. Composite materials offer modern finishes with minimal maintenance requirements.
This design flexibility proves particularly valuable for:
• Premium vehicle showrooms requiring brand-specific aesthetics
• Corporate headquarters matching distinctive architectural styling
• Heritage buildings where doors must harmonise with existing facades
• Mixed-use developments integrating industrial premises within residential zones
• Retail environments requiring sophisticated visual presentation
Substantial Opening Dimensions
The ALR F42 accommodates opening widths up to 7000mm and heights up to 4500mm, providing substantial access dimensions whilst maintaining the structural integrity required for cladding applications. The dimensions are sized to accommodate the additional weight of external materials whilst ensuring reliable long-term operation.
Thermal Performance Considerations
With PU sandwich infill panels within the aluminium framework, the ALR F42 achieves thermal insulation U-values around 2.6 W/(m²·K) before cladding application. The addition of appropriate cladding materials can further enhance thermal performance, particularly when timber or insulated composite panels are specified.
The door's inherent thermal efficiency combined with carefully selected cladding materials creates effective temperature control for premises requiring environmental stability.
Engineering and Installation
Successful implementation of the ALR F42 requires professional planning and installation. Cladding materials must be specified considering weight distribution, fixing methods, and operational flexibility. Hormann provides technical guidance on acceptable cladding types, weights, and attachment systems to ensure optimal performance.
The door framework accommodates standard industrial electric operators or manual operation, depending on door size and cladding weight. Spring-balanced mechanisms are precisely calibrated to the final combined weight, ensuring smooth, low-effort operation throughout the door's service life.
Weather Resistance and Durability
Despite the custom cladding application, the ALR F42 maintains robust weather resistance performance. Proper cladding installation with appropriate weatherproofing ensures rain exclusion and wind resistance. The aluminium framework provides inherent corrosion resistance, whilst cladding material weather performance depends on the selected specification.
Unique Aesthetic Achievement
For projects where standard industrial door appearance proves incompatible with overall architectural vision, the ALR F42 provides the solution. The door mechanism's reliability and engineering excellence combine with complete aesthetic freedom, enabling truly distinctive results that enhance building appearance whilst maintaining functional industrial performance.
