What heroal does

heroal (legal entity: heroal — Johann Henkenjohann GmbH & Co. KG) is a German family-owned manufacturer of aluminium building envelope systems, headquartered in Verl with all production based in Germany and a workforce of 501–1,000 employees. Founded in 1874 as a wooden-shoe business and pivoted to roller shutters in 1950 under Johann Henkenjohann, the company took its current brand identity in 1969 with the invention of the foam-filled aluminium roller shutter slat, from which the name 'heroal' (Henkenjohann rollformt Aluminium) is derived. The portfolio covers aluminium windows, front and sliding doors, facades, sun protection, roller shutters, rolling gates, overhead coverings, fire-protection doors, and insect protection — extended recently by heroal Connect (smart-home integration) and heroal smartScan (digital measurement).

The underlying technology is built on proprietary aluminium-KS composite profiles with a patented insulating crossbar geometry and an in-house PU foam-filling process for narrow-frame passive-house-grade thermal performance (e.g., Uf 0.78 W/m²K on heroal W 77 PH). Surface finishing is differentiated through heroal SD vacuum-wrap wood, concrete, and rust decors and hwr powder coating across 500+ RAL/DB colours and the exclusive Les Couleurs Le Corbusier palette. Security products are certified to RC 3 / RC 4 (ift Rosenheim) and acoustic performance reaches up to 48 dB (Class 5).

The business model is B2B indirect sales through an exclusive, certified channel of 3,500+ Fachpartner (window fabricators, metal construction companies, specialist installers) across Germany, Europe, and select international markets. Pricing is project-quote-based and mediated by partners; end consumers and architects are engaged upstream via dedicated architect advisory services, BIM/CAD data, the heroal Communicator digital workspace, the heroal Academy training program, product configurators, and a Förderservice subsidy-consulting partnership with Fuchs & Eule. Distribution is supported by a 40,000 m² automated central logistics center and a company-owned truck fleet, with sustainability positioning underpinned by AUF membership enabling up to 85% recycled aluminium inputs.
