What Stadur Productions does

Stadur Productions GmbH & Co. KG is a privately held German manufacturer of composite materials, founded in 1982 and headquartered in Hammah, Lower Saxony. The company produces sandwich elements, shower elements, printable lightweight foam boards, and semi-finished polyolefin products across five product lines: Building (sandwich elements for windows, doors, and facades), Bathroom (floor-level shower elements and accessories), Advertising (VISCOM EASYPRINT printable boards), Technics (sandwich elements for vehicle and industrial applications), and Semi-finished products (polyolefin sheets and compounds). Its core proprietary technology is Stadurlon, a high-performance plastic co-developed with BASF in Ludwigshafen as a PVC-free alternative, extruded at Stadur Composite GmbH & Co. KG in Karstädt and used as the top layer in sandwich elements. Stadur operates four German manufacturing sites (Hammah, Stade, Karstädt, Pliezhausen) with vertically integrated production from raw material extrusion through finished sandwich element assembly. Customer-facing sub-products include the FrameTec frame widening system and ProfileTec threshold subbase system, both listed in the DGNB Navigator for sustainable building certification. The company also manufactures an Element:one shower board jointly developed with Lamurista GmbH for exclusive DACH distribution.

Stadur generates revenue through direct, consultation-driven B2B sales of customized composite products on a project-by-project basis. The sales organization is structured by department (Building, Bathroom, Advertising, Technics) with regional coverage in Germany, France, and Eastern Europe. Pricing is not publicly disclosed; customers engage through dedicated Inside Sales Managers and Sales Managers for tailored specifications such as custom lengths up to 7000mm. The go-to-market emphasizes expert advisory consultation supported by trade fair participation (KPA, NUFAM, Batimat), technical documentation downloads, and customer testimonial content. Customers include enterprise window and door manufacturers (Ventana Deutschland), bathroom product distributors (Lamurista), and SMB digital printers (Stichnothe Druckformen GmbH). Sustainability positioning includes PVC-free products, halogen-free materials, emission-free production adhesives, 100% manufacturing waste recycling, and a 4000 m² on-site photovoltaic installation. Ownership is family-controlled through the Sylvester family, with no external private equity or venture capital disclosed.

Core offering

Stadur Productions manufactures composite sandwich elements and high-performance plastic sheets for the building, bathroom, advertising, and industrial sectors. Its core product is the proprietary Stadurlon plastic (developed with BASF as a PVC-free alternative), which is extruded and bonded with foam or PET cores to produce finished sandwich panels, shower elements, printable boards, and industrial components. Products are customized per project (lengths up to 7000 mm, custom thicknesses, profile depths) and sold directly to enterprise customers through a department-specific sales organization.

Product overview

Stadur Productions is a German company specializing in innovative composite materials (Verbundwerkstoffe) with five product lines: Building (sandwich elements for windows, doors, facades), Bathroom (shower elements and accessories), Advertising (VISCOM EASYPRINT printable lightweight foam boards), Technics (sandwich elements for vehicle construction and industry), and Semi-finished products (polyolefin sheets and compounds). The company's core proprietary technology is Stadurlon, a high-performance plastic developed with BASF as a PVC alternative, which serves as the top layer in their sandwich elements. Key sub-products include FrameTec (frame extensions) and ProfileTec (threshold subbases) for thermal insulation, available in standard and PET variants with recycled content. The products are manufactured at multiple German locations (Hammah, Stade, Karstädt, Pliezhausen) and are distributed globally.

Partnerships

Four partnerships are on record, tiered core and minor.

• BASFcoreStrategic or Co-development PartnerSTADUR co-developed the proprietary Stadurlon high-performance plastic material in collaboration with BASF in Ludwigshafen. This was a significant co-development partnership that created STADUR's core proprietary technology — a PVC-free alternative to traditional PVC used in composite sandwich element cover layers. BASF's expertise in chemical engineering combined with STADUR's application knowledge produced the Stadurlon material now manufactured exclusively by STADUR Composite GmbH & Co. KG.
• Ventana Deutschland GmbH & Co. KGcoreStrategic or Co-development PartnerLong-standing partnership where STADUR supplies custom ProfileTec threshold profiles for Ventana's special window constructions. STADUR developed customized threshold profiles for lift-and-slide doors meeting specific requirements for thermal insulation, stability, and custom dimensions up to 7000mm. The partnership includes joint quality standards development and ongoing collaboration on new product developments.
• Lamurista GmbHcoreStrategic or Co-development PartnerJoint product development partnership resulting in the Element:one shower board for seamless surface applications. STADUR and Lamurista co-developed a custom shower board with integrated drainage channel and custom slope milling. The product is exclusively distributed by Lamurista in the DACH region. The collaboration is characterized by mutual trust and open exchange.
• NFF - Nordtreff Fenster FassademinorStrategic or Co-development PartnerSTADUR is a member of the NFF (Nordtreff Fenster Fassade), an industry association of 13 companies from the window and facade sector.
