What aluminiumwerken cleirbaut does

Aluminiumwerken Cleirbaut, operating through its Hungarian legal entity Cleirbaut Ablak Kft. (registered in Dombóvár, company number 17-09-010303), is a family-owned manufacturer and installer of custom aluminum and PVC windows, doors, sliding doors, and curtain-wall systems. The company was founded in Belgium in 1966 and has been led by managing director Yentl Cleirbaut, maintaining continuous family ownership for over 50 years. Its products are built on European third-party profile systems — primarily Aliplast (Star 75, Max Light, Visoglide, Ultraglide, Ecoline) and Van Beveren (MR50 curtain wall) — which Cleirbaut integrates, customizes, manufactures, and installs under its own brand for end customers.

The company's portfolio spans three main aluminum categories (windows & doors, sliding doors, and curtain walls) plus a PVC line, with performance certifications including Uw values as low as 0.9 W/m²K, RC2/RC3 burglary resistance, up to 42 dB sound insulation, and water/wind tightness ratings up to E2100/C5. It serves both residential customers (family houses, apartments, townhouses) and commercial/institutional projects (offices, schools, airports, hospitals, retail) across four European countries: Belgium, the Netherlands, France, and Hungary. Manufacturing is concentrated at the Dombóvár facility in Hungary, with a regional headquarters in Bonheiden, Belgium.

Cleirbaut generates revenue through one-time project-based sales of custom-manufactured and installed window, door, and curtain-wall systems, with no published pricing, no subscription or recurring model, and no disclosed named enterprise customers. Customer acquisition is driven by a website quote-request funnel and direct enterprise field sales. In September 2025, the company secured a 28.08 million HUF non-reimbursable EU grant (50% of a 56.16 million HUF project) under the GINOP_PLUSZ-1.2.4-25-2025-00283 program to fund technology modernization, digitalization, and new production equipment at the Dombóvár site through February 2027. The company has no disclosed revenue, no external investors, and no M&A activity.
