ROCKWOOL France

What ROCKWOOL France does

ROCKWOOL France S.A.S. (registration no. 305394397) is the French operating subsidiary of Denmark-based ROCKWOOL A/S, the world's leading manufacturer of stone wool insulation. Headquartered at 111 rue du Château des Rentiers, 75013 Paris, the entity was founded in 1978 and operates with 501–1,000 employees supporting wholesale distribution of stone wool building materials to the French construction market.

The company's core offering is a portfolio of stone wool insulation products derived from volcanic rock and produced using proprietary melting technology. Key SKUs include AFB (Acoustical Fire Batt) for interior steel and wood stud walls, Cavityrock for exterior cavity and rainscreen assemblies, Comfortboard 80/110 as rigid exterior continuous insulation, Comfortbatt for residential thermal applications, Safe'n'Sound for fire-and-sound interior partitions, and Toprock DD for low-slope roofing. Differentiated performance claims center on fire resilience above 1000°C, 65+ year maintenance-free durability, moisture repellence, thermal efficiency (100x lifetime energy savings versus production), and acoustic absorption.

ROCKWOOL France monetizes almost exclusively through B2B hardware sales of these insulation products, distributed via a hybrid channel of building supply retailers, specialist insulation distributors, and direct enterprise sales relationships with commercial contractors, developers, architects, and specifiers. Pricing is quote-based and not publicly disclosed. Support functions include technical documentation, building-science consultation, and a LEED Letter Generator to embed products into French and EU sustainable-building certification workflows. The entity also benefits from group-level sister brands (Rockfon, Rockpanel, Grodan, Lapinus) for cross-selling into acoustic, façade, horticultural, and engineered-fiber verticals.
