Plattenhardt + Wirth

What Plattenhardt + Wirth does

Plattenhardt + Wirth GmbH is a German family-owned manufacturer and builder specializing in cold storage construction (Kühlraumbau) and industrial construction (Industriebau), founded in 1965 and headquartered in Meckenbeuren, Germany. The company designs, fabricates, and installs custom cold rooms, deep-freeze rooms, controlled atmosphere (CA/ULO/DCA) fruit storage, banana ripening rooms, clean rooms and hygiene rooms for pharmaceutical and medical technology, sandwich-panel enclosures for high-bay warehouses and AutoStore automated storage systems, and turnkey food processing and aquaculture facilities. Customers include large enterprise food retailers (ALDI Süd, ALDI Nord, Hofer, EDEKA), food processors (Nestlé, Wiesenhof, Milei, Pfalzgraf, Rügenwalder Mühle, Goldsteig), pharmaceutical firms (Vetter) and logistics operators (Lufthansa Cargo, Galliker, Univec) across the DACH region.

The company's underlying technology centers on sandwich panel building systems with PIR and MIWO cores, used to construct gas-tight, fire-resistant, and insulated envelopes. Proprietary product systems include the registered Glasbord® glass-reinforced plastic panel line for hygiene interiors, the Flextor flexible door system, gas-tight CA/ULO/DCA enclosures, and inertization enclosures for fire prevention in automated warehouses, data centers, and lithium battery storage. Execution is delivered through in-house planning, fabrication, assembly, and service departments staffed by qualified technicians and specialist construction managers, with no resellers or distribution intermediaries.

Plattenhardt + Wirth operates a hybrid revenue model: the majority of revenue is generated through project-based custom construction (one-time license equivalent), supplemented by recurring maintenance and safety inspection contracts (including mandatory ASR A1.7 inspections), and a transactional spare parts business. Pricing is project-specific and quote-based, with multi-year contracts typical. The company sells directly through twelve offices in Germany and Austria and a wholly-owned Austrian subsidiary (Plattenhardt + Wirth Österreich GmbH), serving end customers across Germany, Austria, and Switzerland. Marketing is primarily direct, supported by a multilingual website (German, English, French, Italian), downloadable PDF brochures, and sustained employer brand investment (Kununu Top Company 2022–2026).

Direct peers

• Trimo d.o.o. Slovenian manufacturer of sandwich panels and modular building envelopes serving industrial and cold storage construction. Direct comparability on sandwich panel technology for cold rooms, deep-freeze, and industrial envelopes.
• Goldbeck GmbH: German turnkey industrial and commercial construction firm operating a system-building approach with in-house prefab and project delivery. Most directly comparable to Plattenhardt + Wirth on turnkey industrial building delivery in DACH, though at substantially larger scale.
• Isopan S.p.A. Italian manufacturer of insulated metal panels for industrial, commercial, and cold storage roofing and walls. Comparable as a sandwich panel specialist targeting the same end markets, including cold rooms and food processing facilities.
• BREMER AG: German turnkey construction company focused on industrial, logistics, and commercial buildings. Comparable as a DACH-based general contractor competing for similar turnkey project scopes, including cold storage and logistics hubs.
• Lindner Group KG: German family-owned specialist contractor for interior fit-out, partitions, ceilings, and clean rooms. Comparable on clean room and hygiene room construction for food processing and pharmaceutical end customers, though broader in scope.
• Metecno S.p.A. Italian-based global manufacturer of sandwich panels and PU/PIR insulated roofing/wall systems. Directly comparable product overlap with Plattenhardt + Wirth's PIR and MIWO core sandwich panel systems.

Broad incumbents

• Viessmann Climate Solutions: German-established provider of HVAC, refrigeration, and cold chain solutions. Overlaps with Plattenhardt + Wirth on refrigeration and cold storage but at much broader scope and scale, spanning equipment rather than building envelope specialization.
• Kingspan Group plc: Irish global leader in insulated panels and building envelope solutions. Comparable on sandwich panel technology and cold store envelope systems, though at vastly larger scale and with a manufacturing-led (rather than specialty contracting-led) model.

Others

• Bitzer Kühlmaschinenbau GmbH: German global manufacturer of commercial and industrial refrigeration compressors. Adjacent rather than direct: supplies refrigeration equipment that is installed inside the cold storage facilities that Plattenhardt + Wirth constructs, making them ecosystem partners/adjacents.

Regional players

• W. Hundhausen Bauunternehmung GmbH: German specialty construction firm with industrial and commercial building expertise. Comparable as a regional DACH specialty contractor competing for similar turnkey industrial and commercial building scopes, though with less specialization in cold storage.
