PwC Switzerland is pleased to announce that it has advised ISO-CENTER AG ("ISO-CENTER"), a leading Swiss distributor of technical insulation materials and solutions, on its sale to Baustoff + Metall Gesellschaft m.b.H. ("Baustoff + Metall"). PwC acted as lead advisor to ISO-CENTER and its shareholder.
Headquartered in Basel, Switzerland, ISO-CENTER is one of Switzerland’s leading providers of technical insulation and insulation materials for building technology and industrial applications. With more than 35 years of market experience, over 3’500 products, five logistics sites and a highly digitised E-Shop, the company serves customers across Switzerland with reliable product availability, technical know-how and short delivery times.
Built over two generations by the Eisenhart family, ISO-CENTER has developed from its entrepreneurial roots into a well-established specialist in the Swiss insulation market. Under the family’s stewardship, the company expanded across Switzerland, broadened its product and service offering, and invested in logistics, digitalisation and customer service. Throughout this growth journey, ISO-CENTER remained firmly rooted in its family-owned heritage and in the values that have shaped the business for more than 35 years.
With a clear sense of responsibility towards employees, customers, suppliers and the company’s legacy, the shareholder initiated a highly selective succession process to secure ISO-CENTER’s long-term future. Baustoff + Metall was chosen as the preferred partner due to its family-owned structure, shared entrepreneurial mindset, strong cultural fit and long-term perspective. The transaction therefore provides a strong foundation for ISO-CENTER to preserve its identity and continue its successful development under new ownership.
Baustoff + Metall, headquartered in Vienna, Austria, is a family-owned, highly specialised wholesale and full-range provider of products for dry construction, technical insulation, roof and facade insulation, timber construction, floor screed and building components. The group combines specialist trade, industrial activities and consulting capabilities under one roof and operates an extensive European footprint.
The transaction represents a strong strategic fit for both companies. ISO-CENTER gains a long-term industrial partner with a complementary product portfolio, broad European network and deep sector expertise, while Baustoff + Metall strengthens its technical insulation offering and enters the Swiss market. Together, the companies are well positioned to ensure continuity for employees, customers and suppliers and to support further growth.
The transaction was signed on 7 July 2026. The parties have agreed to keep the transaction details confidential.
