Kozijnen Unie

What Kozijnen Unie does

Kozijnen Unie is a privately held Dutch wholesale and installation company headquartered in Deurne, Netherlands, specializing in windows and door frames (kozijnen) made from Kunststof (PVC), aluminium, and wood. The company sources frames directly from six European manufacturers — Aluprof, Reynaers, and Schüco for aluminium and mixed systems, and Gealan, Aluplast, and K-vision (Kömmerling) for PVC — and resells them under its own brand alongside custom wooden frames in Sapeli Mahonie, Meranti, Red Grandis, and Accoya. Product offerings include fixed windows, tilt-turn (draai-kiep) windows, front and back doors, sliding doors, and folding doors, configured online through a free quote calculator with options for HR++ or triple glazing, foiled wood-look finishes, and bespoke sizing.

The company's go-to-market combines direct-to-consumer e-commerce (kozijnenunie.nl) with field sales to contractors (aannemers) and construction companies (bouwbedrijven), and includes a single retail showroom in Deurne. Revenue is generated primarily through one-time unit sales (€300–€4,500 per window/door depending on material and size), optional professional installation services, and accessory sales (screens, ventilation grilles, roller shutters). The website is published in 13 languages, and delivery plus installation extend across the Netherlands and Belgium. Pricing is positioned 10–20% below competitors via direct factory sourcing, supported by a 10-year frame warranty and 5-year hardware warranty, free delivery above €2,500, and 14-working-day lead times.

Operationally, Kozijnen Unie does not develop proprietary technology; its competitive edge rests on supplier relationships, cost-efficient distribution, and bundled installation rather than on a software or product platform. No disclosed revenue, headcount, ownership structure, or financial backers were identified in the source data, and the company holds no disclosed patents, awards, or certifications.

Direct peers

• Belisol: One of the largest window and door installers in Belgium and the Netherlands, operating a multi-city showroom-and-installer network. Directly comparable in business model as a multi-brand dealer with own installation teams serving both trade and consumer customers.
• Toeleveringonline.nl: Online Dutch building materials supplier explicitly referenced in Kozijnen Unie's pricing analysis as the direct price benchmark. Operates an e-commerce storefront selling construction materials to contractors and consumers across NL.

Broad incumbents

• Gealan: German manufacturer of PVC window and door profile systems (S 9000, S 8000). Direct overlap with Kozijnen Unie's Kunststof range; comparable as a profile-system manufacturer serving European dealers.
• Aluprof: Polish leading European manufacturer of aluminium window, door, and facade systems. Comparable in product category as both supplier and competitor in the aluminium frames segment across European markets.
• Reynaers Aluminium: Belgian global manufacturer of premium aluminium window, door, and facade systems. Functions as both a key supplier and a potential competitor if Reynaers expands dealer-direct or end-consumer channels in Benelux.
• Schüco: German global manufacturer of innovative window, door, and facade systems in both Kunststof and aluminium. Key supplier to Kozijnen Unie and broad player across European markets.
• Weekamp: Dutch manufacturer of custom wooden window and door frames, comparable in product category and Dutch market focus but operating as a manufacturer rather than as a multi-brand reseller/installer.
• Deceuninck: Belgian global manufacturer of PVC window and door profile systems. Overlaps with Kozijnen Unie's Kunststof category (competing with Gealan, Aluplast, K-vision) but at the manufacturer level rather than as an installer.
