Saint-Gobain sold HKO and Deltec to DUBAG Group, advancing portfolio optimization and focusing on core strategic growth businesses.
Saint-Gobain has finalized the divestment of HKO, its Germany-based high-temperature industrial insulation textile business, along with its French subsidiary Deltec, marking another step in the company’s ongoing portfolio optimization strategy. The acquisition has been completed by a fund managed by DUBAG Group, a private investment firm specializing in the development and transformation of industrial businesses.
HKO and Deltec are recognized for their expertise in manufacturing advanced technical textile components designed for high-temperature insulation applications. These specialized products are widely used across a range of industries, particularly in the automotive and industrial sectors, where thermal protection and insulation performance are critical. The businesses have built strong capabilities in producing materials that help improve energy efficiency, enhance safety, and support demanding industrial processes that operate under extreme temperature conditions.
The transaction includes HKO’s manufacturing operations located across several sites in Germany and France. In Germany, the company operates industrial facilities in Oberhausen, Beuren, and Leinefelde, while its French subsidiary Deltec maintains a production site in Wattignies. Together, these facilities form a well-established manufacturing network that serves customers throughout Europe and other international markets.
During 2025, the combined HKO and Deltec operations generated approximately €45 million in revenue, reflecting their established position within the specialized industrial insulation materials market. The business also employs around 220 people across its various locations, contributing technical expertise and manufacturing know-how to the production of advanced thermal insulation solutions.
The sale underscores Saint-Gobain’s continued commitment to reshaping and strengthening its business portfolio. By divesting operations that are no longer considered core to its long-term strategic priorities, the company aims to focus resources on areas where it sees stronger growth opportunities, greater innovation potential, and enhanced value creation. The transaction aligns with Saint-Gobain’s broader objective of streamlining its operations and concentrating on businesses that support its ambitions in sustainable construction, light and sustainable building solutions, and high-performance materials.
The divestment is consistent with the goals outlined in Saint-Gobain’s “Lead & Grow” strategic plan. This roadmap is designed to accelerate profitable growth, improve operational efficiency, and reinforce the company’s leadership positions in selected markets. Through targeted acquisitions and selective disposals, Saint-Gobain seeks to continuously optimize its business mix while improving overall competitiveness and long-term financial performance.
For DUBAG Group, the acquisition represents an opportunity to further develop a niche industrial business with specialized technological expertise and an established customer base. DUBAG has a track record of investing in industrial companies and supporting their growth through operational improvements, strategic repositioning, and long-term development initiatives. Under its new ownership structure, HKO and Deltec are expected to continue serving their customers while pursuing new opportunities for expansion and innovation in the industrial insulation sector.
The completion of this transaction highlights the ongoing trend among major industrial companies to actively manage their portfolios, focusing on core growth segments while transferring specialized businesses to owners better positioned to support their next stage of development.
