Harryvan Kozijnen

What Harryvan Kozijnen does

Harryvan Kozijnen B.V. is a Dutch custom wooden window and door manufacturer founded in 1930 and headquartered at Korenmolendreef 11 in Slochteren, Groningen. The company produces exterior frames (buitenkozijnen), interior frames (binnenkozijnen), and specialty/custom products including pivot doors (taatsdeuren), folding doors (vouwpui) with Centor E3 hardware, doors for monumental buildings, and untreated frames for natural-aging applications. Manufacturing is performed entirely in-house in a modern factory, combining CNC-controlled machine programming with traditional woodworking craftsmanship; an integrated digital workflow links quotation, CAD drawing, machine-program generation, material procurement, and invoicing in a single system. The company holds KOMO, CE, Hout100%, FSC, and PEFC certifications and processes FSC/PEFC-certified wood as standard.

The company operates a B2B enterprise field-sales model targeting construction companies, contractors, builders, and architects across Northern Netherlands (Groningen, Drenthe, Friesland, Overijssel, and Flevoland). Revenue is generated through quote-based, project-by-project pricing on custom orders, with multi-year contract cadence and pricing dependent on wood species, dimensions, finish, and complexity. Notable recurring relationships include Van Calkar Bouwbedrijf (partnership since 1972, renewed 2012), architect firm JK Houses, and corporate account FritsJurgens (pivot-door partner). Marquee projects include Provinciehuis Groningen (15th-century provincial building), Stadhuis Meppel (new city hall by Kraaijvanger architects), Hanzehogeschool Groningen, Theater De Spiegel Zwolle (opened by Queen Beatrix in 2006), and the Johan Willem Frisokazerne renovation. The company is privately held, with Marcel Beuzenberg as Algemeen directeur (General Director), and operates as part of a group that includes sister company De Vries Trappen (stairs manufacturer) under shared ownership.

Scale indicators3 records

Recent moves6 records

Expansion highlights5 records

Others

• BUVA: Dutch hardware manufacturer of multi-point locking systems, ventilation grilles, and door hardware, headquartered in the Netherlands. Listed by Harryvan as a standard hardware supplier, making it a domestic adjacent partner in the same wood window/door value chain.
• Hoppe: German family-owned hardware supplier of handles, escutcheons, and locking systems for windows and doors; explicitly specified by Harryvan as standard hardware on its products. A supplier rather than a competitor, but a critical adjacent partner in the same custom wood window value chain.
• Centor: Australia-based hardware specialist for folding door and large-opening systems (Centor E3 hardware up to 115 kg). Harryvan integrates Centor hardware into its vouwpui folding doors, making Centor an adjacent enabling supplier rather than a direct competitor.

Direct peers

• Finstral: South Tyrolean family-owned manufacturer of made-to-order wood-aluminum and PVC windows and doors. Directly comparable to Harryvan's custom-fabrication, premium-quality positioning and integrated factory model, although Finstral operates at significantly greater scale across multiple European countries.
• Internorm: Austrian family-owned window manufacturer producing premium wood, wood-aluminum, and PVC windows across Europe. Comparable to Harryvan as a custom-focused wood window maker, but at substantially larger scale, competing for similar high-end residential and heritage specifications.

Broad incumbents

• Deceuninck: Belgian broad incumbent in PVC window and door profile systems, supplying fabricators and construction OEMs across Europe. Operates in the same Dutch fenestration value chain as Harryvan but is a material-substitution alternative (PVC) rather than a custom wood competitor.
• Reynaers Aluminium: Belgian-headquartered broad incumbent in aluminium window, door, and curtain-wall systems, active across the Benelux construction market. Competes with Harryvan for commercial and high-end residential facade projects, but with a much broader product portfolio spanning aluminium and not specialising in solid wood.
• Schüco: German global broad incumbent for window, door, and facade systems in aluminium, PVC, and steel. Targets the same B2B Dutch construction and institutional customer base as Harryvan, but as a large, multi-material systems supplier rather than a custom solid-wood fabricator.
• VELUX: Danish broad incumbent in roof windows and skylights, owned by the VKR Foundation. Not a direct wooden frame competitor but shares the same architectural/builder specification channel in the Netherlands and operates at vastly larger scale with adjacent window products.
• Hörmann: German family-owned broad incumbent in doors, frames, and building envelope products, active across Europe including the Netherlands. Overlaps with Harryvan in wooden and steel door/frame categories but operates at much greater scale and with a broader, standardised product portfolio.
