ISOCELL is natural thermal insulation made from cellulose fibers, which is created by recycling clean, unmixed newspaper. Coarsely fibered, mixed with mineral salts and ground in a mill, Isocell cellulose makes it rot-proof and fire-resistant. Production of cellulose insulation takes place at four of our own plants, in Hartberg (Austria), Berlin (Germany), Schoppen (Belgium) and in Tibro (Sweden).  Two more plants in France (Morlaix and Servian) operate with ISOCELL know-how.
