What Cezam does

Cezam is a Belgian manufacturer of PVC and aluminum windows, doors, and sliding systems, headquartered in Sensenruth (Bouillon) with a second PVC fabrication facility in Bertrix. The company produces a structured product portfolio spanning three PVC window systems (Optimum OP74, Excellium EX83, Kubus KS100), three aluminum window systems (Ecofutural EF65, Star 75, Star 90), three aluminum sliding systems (Greenslide, Proglide, Ultraglide), two PVC sliding systems (SI 150, EX 190), and corresponding door lines, plus complementary products including verandas, curtain walls, dome roofs, fire-rated joinery, garage doors, interior partitions, bioclimatic pergolas, and mosquito nets.

All products carry CE marking.

Cezam operates exclusively through a B2B channel: a network of professional distributors and installers covering Wallonia, Brussels and South Flanders in Belgium, Northern France (including Lille, Reims, Sedan, Metz), and the entirety of Luxembourg, totaling more than 500 collaborators across the three countries. End customers can submit online quote requests through cezam.net, which are routed to local distributors for measurement, quoting, installation, and after-sales service. Pricing is quote-based and not publicly disclosed. Core technology partnerships with Aliplast (aluminum profiles), Gealan (Acrylcolor), and Siegenia (ECOPASS thresholds) underpin the product platform, with secondary integrations to Somfy (motorization), Renson (ventilation), Fuhr (hardware), and Hormann/LDoor/Winsol (garage doors). Annual production capacity is stated at 30,000 joinery pieces.

The business model is straightforward unit-sales manufacturing: Cezam fabricates finished joinery systems in Belgium and sells through trade-channel partners who bundle installation and after-sales services.

Direct peers

• Aliplast: Belgian aluminum profile systems supplier and fabricator that both supplies profiles to Cezam and competes with it in finished aluminum windows and doors. Strong regional overlap in BeNeLux and a comparable emphasis on thermal performance and color-fast Qualicoat-Seaside finishes.
• Finstral: South Tyrolean fabricator of PVC, aluminum, and timber-aluminum windows and doors sold across Italy, Germany, Switzerland, and Austria. Comparable premium positioning, vertical integration, and direct relationships with architects and installers for residential renovation.
• Deceuninck: Belgian PVC window and door systems company with strong presence across Europe and North America. Comparable in PVC window technology, design focus, and Belgian heritage; competes with Cezam for premium PVC renovation and new-build projects in the BeNeLux region.
• Reynaers Aluminium: Belgian-headquartered fabricator of premium aluminum windows, doors, and sliding systems for residential and commercial projects across Europe. Direct competitor in the same Belgian aluminum fenestration segment, with comparable 'Made in Europe' premium positioning and overlapping distribution model.
• Gaulhofer: Austrian premium window and door manufacturer specializing in timber-aluminum and PVC systems with strong energy efficiency certifications. Comparable product positioning and reliance on certified, professional installer channels in German-speaking and adjacent markets.
• DAKO: Polish manufacturer of PVC, aluminum, and timber windows and doors supplying Western European markets through distributor networks. Comparable business model (fabricator selling through dealers), with strong overlap in distributor-led residential renovation demand.
• Internorm: Austrian manufacturer of premium PVC, timber-aluminum, and aluminum windows and doors sold across Europe. Comparable in product positioning (premium, energy-efficient fenestration), target customer (professional installers and end consumers), and emphasis on thermal/acoustic performance certifications.

Broad incumbents

• Schüco: German global incumbent in aluminum and PVC window, door, and façade systems with operations in over 80 countries. Larger and broader portfolio than Cezam, but directly competes in premium European fenestration projects and pulls on the same professional installer channel.
• Hörmann: German market leader in garage and entrance doors that also supplies Cezam's garage door line. Larger incumbent with broader product portfolio and pan-European brand recognition; competes indirectly through complementary door categories in residential construction.

Others

• Gealan: German PVC profile systems manufacturer that supplies Cezam with the exclusive Acrylcolor surface technology. Not a direct fabricator competitor, but an upstream technology partner whose licensing terms and capacity directly shape Cezam's differentiated product offering.
