Groven+

What Groven+ does

Groven+ is a Belgian KMO (small-to-medium enterprise) that designs, fabricates, installs, and maintains architectural facades, with origins tracing to Groven SA (1965) and the current entity established in 1998. The company operates three units — Groven+ Gevelbouw (facade construction), Groven+ Portal (portal and entry systems), and Groven+ Service (maintenance and remediation) — and is integrated into the B-Steel division of the Buyck Group since 2016, with 51-100 employees. Its core products include curtain walls, windows with thermal break, structural glazing (VEC), domes, facade cladding, and access doors, supported by a patented Five-S facade system and a 7,200 m² CNC-equipped production facility in Belgium. Service contracts of up to 10 years create a recurring revenue layer beyond the initial construction project.

The business model is B2B enterprise sales into the non-residential construction and property management sectors, with pricing structured per project and per maintenance contract. Groven+ serves architects, developers, general contractors, and building owners across the Benelux, Northern France, and the Paris region, with a footprint that includes Belgium, France, and the Netherlands. Notable delivered projects include Casa Ferrero, Antwerp Bosuil Stadium, Brucity Centre 58, Belliard 9, The Wings Diegem, Havenhuis, and Knokke Hospital, several of which carry BREEAM, WELL, and DGNB certifications. The company's recent merger of Groven+ NV and Groven+ Portal SA in June 2024 consolidated its construction and portal operations under a single legal entity, simplifying go-to-market and joint bidding on integrated facade-plus-portal tenders.

Scale indicators4 records

Recent moves18 records

Expansion highlights4 records

Broad incumbents

• Technal (Hydro Building Systems): Aluminum building systems brand of Norsk Hydro, supplying curtain walls, windows, and solar protection. Overlaps with Groven+ on commercial facade product lines and benefits from parent Hydro's raw-material integration.
• Aluprof: Polish aluminum systems manufacturer with growing Western European presence. Competes with Groven+ on aluminum curtain walls, windows, and facade cladding, especially on price-sensitive non-residential tenders.
• Permasteelisa: Large international facade engineering and contracting group owned by Manni Group. Competes with Groven+ on premium curtain wall and structural glazing tenders but operates at significantly larger scale and broader geographic footprint.
• Wicona (Hydro Building Systems): Aluminum facade, window, and door systems brand within Hydro. Directly comparable to Groven+ on unitized curtain walls and high-performance commercial envelopes across European markets.

Direct peers

• Seele Group: German glass-engineering specialist executing complex structural glazing and free-form facades (e.g., Apple Stores). Closely comparable to Groven+'s Five-S Coque and structural glazing work on architecturally demanding non-residential projects.
• Schüco: German-headquartered global leader in aluminum curtain wall, window, and facade systems. Directly competes with Groven+ in Benelux/France architectural glazing on large non-residential projects, with comparable VEC and unitized facade offerings.
• Reynaers Aluminium: Belgian aluminum facade and window systems manufacturer serving the same Benelux/French non-residential market. Direct overlap with Groven+ on curtain wall, thermal-break window, and bespoke profile projects.

Others

• FAC Belgium (Federatie Aluminium Constructeurs): Belgian federation of aluminum constructors that awards the Quality Label held by Groven+. Industry body rather than competitor, but defines certification and quality standards against which Groven+ and peer installers are benchmarked.

Emerging players

• Aluk Group: Italian-headquartered aluminum window, door, and curtain wall systems supplier active in Western Europe. Overlaps with Groven+ on mid-market commercial facade projects in Benelux and France.
• Jansen (voestalpine): Steel and stainless-steel profile systems specialist within voestalpine, focused on fire-rated facades and steel-glass construction. Comparable to Groven+'s stainless-steel Five-S frames and increasingly relevant for complex specialty facades.
