What ck kozijnen does
CK Kozijnen B.V. is a privately held Dutch installation company founded in October 2009 by Cas Kunst and headquartered in Dordrecht, Netherlands, at Planckstraat 7. The company supplies and installs custom-made facade elements — window frames, entrance and balcony doors, sliding walls, dormers, facade cladding, sun protection systems, screens, roller shutters, and home extensions — in uPVC, aluminum, and wood, with HR++ double glazing as standard. Its uPVC frames use a five-chamber profile system with galvanized steel reinforcement, UV filters, and reduced plasticizer content for durability, and sliding wall systems carry a 10-year warranty.
CK Kozijnen serves two segments from a single showroom: a primary private/homeowner market and a secondary business market comprising contractors, ZZP'ers, timber companies, construction firms, and homeowners' associations (VVE's). The go-to-market is showroom-led direct sales: customers view products at the Dordrecht location, receive personal consultation, and request quotes either in person or via the ckkozijnen.nl website. The company employs a fixed team of in-house installers, providing end-to-end service from quotation through delivery and fitting.
Revenue is generated on a project basis through one-time sales of manufactured-to-order products bundled with installation services; pricing is not publicly disclosed and is provided on quote. Marketing relies on the showroom, Google reviews, project photography galleries, social media, and customer referrals rather than paid acquisition. The company has operated continuously for 15 years, reports a 9.3/10 average customer satisfaction rating, and has been named best company in the Dutch construction sector for nine consecutive years based on customer feedback. It is GDPR-compliant, has no disclosed investors or parent company, and shows no M&A, funding, or multi-site expansion activity in the available data.

One partnership is on record.
- Stichting ANDERSminorCK Kozijnen supports Stichting ANDERS Drechtsteden, a charitable foundation. In a specific project, they supplied a new uPVC door for a Dordrecht resident who needed to accommodate a mobility scooter in their shed. This represents the company's social responsibility initiative and community involvement rather than a commercial partnership.

ck kozijnen competitors and assessment
Company assessmentDirect peers
- Deceuninck: Belgian-headquartered global manufacturer of PVC window and door systems with strong Dutch market presence through a dealer/installer network. Highly comparable because Deceuninck supplies the same uPVC profile category (windows, doors, sliding systems) that CK Kozijnen installs, and competes for the same Dutch residential renovation end-customer.
- Reynaers Aluminium: Belgian aluminum window, door, and sliding-system manufacturer with extensive Dutch dealer coverage. Directly comparable to CK Kozijnen's aluminum product line (aluminum kozijnen, hef-schuifdeuren, schuifpuien), competing for the same Dutch premium residential and commercial facade projects.
- Veka: German PVC profile manufacturer serving European window fabricators and installers including in the Netherlands. Directly comparable to CK Kozijnen on the uPVC kozijnen category — Veka supplies the five-chamber-class profiles that competing Dutch installers and CK's competitors use to fabricate window frames.
- Aluprof: European aluminum window, door, and facade systems manufacturer with active Dutch market sales. Comparable to CK Kozijnen's aluminum kozijnen, sliding-door, and facade-cladding product lines, serving the same commercial and high-end residential Dutch market.
- Gealan: German PVC window and door profile manufacturer with Dutch distribution. Comparable to CK Kozijnen on uPVC windows and doors, supplying the same type of multi-chamber profile systems that Dutch installers like CK compete with at the end-customer level.
- Inoutic (Profine Group): European PVC window and door systems brand under Profine, active in the Dutch market. Comparable to CK Kozijnen's uPVC kozijnen and deuren product range, competing for Dutch residential renovation projects through installer networks.
- Heroal: German manufacturer of aluminum window, door, sliding, and sun-protection systems. Directly comparable to CK Kozijnen's aluminum kozijnen, schuifpuien, and zonwering/rolluiken product categories, serving the same Dutch residential and light-commercial segment.
Broad incumbents
- Schüco: German global leader in window, door, and facade systems with a wide Dutch partner network. Comparable to CK Kozijnen across the full facade portfolio (windows, doors, sliding walls, sun protection) but operates as a much larger, broader portfolio player rather than a regional specialist.
- Kawneer: Global aluminum architectural window, door, and curtain-wall systems brand. Comparable to CK Kozijnen's aluminum window/door offering but operates as a much larger broad-line commercial facade incumbent rather than a residential specialist.
Regional players
- Kozijnen.nl: Dutch online-first kozijnen retailer and installer serving customers across the Netherlands. Closest business-model peer to CK Kozijnen (B2C kozijnen specialist), but operates nationally with a digital lead funnel rather than from a single regional showroom like CK.
