What Klug-Conservation does

Klug-Conservation (legal entity Walter Klug GmbH & Co. KG) is a German family-owned manufacturer of conservation and archival materials, founded circa 1870 and headquartered in Immenstadt, Germany. The company produces age-resistant papers, conservation and mounting boards, corrugated boards, honeycomb panels, archival boxes, enclosures, tubes, folders, glues, and accessories designed for long-term preservation of movable cultural assets. Proprietary technical capabilities include a transparent archival paper manufactured from 100% pure virgin fibers free from sulfur, acids, lignin, plasticizers, and metals, and products certified to the Photographic Activity Test (ISO 18916), DIN EN ISO 9001, and FSC standards.

The company serves archives, museums, libraries, conservators, and professional art framers across D-A-CH, France, North America, South America, Oceania, and Asia via overseas sales partners. Its go-to-market is sales-led with regional sales teams for D-A-CH, Export, and France, supplemented by an e-commerce storefront and online mount and box configurator tools for custom product specification. The revenue model is one-time and project-based sales of archival products, with quotation-based pricing for many items and custom-configured products manufactured exclusively per customer specification and excluded from withdrawal rights.

Klug-Conservation has launched new SKUs in early 2026 (KS10 archival box; Passepartout board 024 and museum board 025) and joined the Climate Neutral Allgäu 2030 Alliance. Leadership consists of Managing Directors Peter Lang and Peter Langhammer. The company does not disclose revenue and has no external private equity or venture capital investors, reflecting an organically-financed, multi-generational family business operating in a specialized conservation materials niche.
