Wijnsma Kozijnen

What Wijnsma Kozijnen does

Wijnsma Kozijnen B.V. is a Dutch family-owned manufacturer of plastic (PVC) and aluminum window frames and doors, headquartered and produced in Drachten, Friesland. The company runs a fully in-house factory equipped with a modern machine park and robotization, with stated annual capacity of approximately 12,000 window frames. Production is built on GEALAN profile systems, notably the S9000 NL series with acrylcolor® coating technology, and the portfolio spans Reno (renovation) frames, Prefab Stelkozijnen mounting frames, GEALAN kunststof kozijnen, and a Maatwerk & Specials line for non-standard specifications. The firm has over 20 years of operating history in kunststof kozijnen for renovation and project-based construction, with 11–50 employees and no disclosed external investors, parent, or M&A activity.

The go-to-market is a direct B2B sales motion targeted exclusively at construction professionals: contractors (aannemers), installation companies (montagebedrijven), property maintenance firms, and housing corporations. Pricing is project-based, quote-driven, and not publicly listed, with multi-year contracting arrangements. The commercial front-end is Wijnsma Portaal — an Azure-hosted online configurator launched to enable buyers to size and specify frames, receive instant quotations, generate branded client proposals, and track project status. Distribution is direct from the Drachten factory to project sites, with no intermediaries or resellers. Geographic focus is Northern Netherlands, primarily Friesland and adjacent cities (Leeuwarden, Heerenveen, Sneek, Dokkum, Harlingen, Bolsward, Lemmer, Burgum, Joure, Wolvega, Gorredijk), though documented projects extend to Purmerend, Zaandam, Lelystad, Wormerveer, Groningen, Rotterdam, Den Haag, Enschede, and Scheemda.

The customer base includes over 100 named partners and references more than 300 companies trusting Wijnsma, with disclosed enterprise customers such as Parteon, Centrada, WormerWonen, WVH, VvE Robert Kochplaats, Stebru Bouw, Bouwbedrijf Jan Vet, Bouwbedrijf KBK Volendam, and Lenferink. Revenue figures are not publicly disclosed, the company is privately held as a Dutch B.V. (KvK 57317208), and the business has won the 2019 Duurzaam Bouwen Award (Gouden) for the School De Leister Igge Opeinde project and holds a Trustindex rating of 4.63 across 631 reviews.
