Resine Isolanti, since 1929


Today, as then, the company's mission is to continually improve the performance of materials, without ever losing sight of cost competitiveness and environmental protection.

Our story.

Resine Isolanti O. Diena Srl was established in Milan in 1929 as a company specializing in thermal insulation. With the advent of the Second World War, the business addressed itself to naval and hospital sectors. The end of the conflict and the momentum created by Italy’s reconstruction pushed the company to resume research at full capacity and to accelerate development with ever greater determination in the field of organic resins. The objective was to produce expanded insulating materials for both civil and industrial sectors. These were years of great growth, in which expanded urea (Aerocel Montecatini) and the first rigid resin casting foams were conceived. In 1952, the company continued expansion thanks to the production know-how of Montecatini, establishing its own factories in Bresso. The market success, the advanced research and extensive analysis of laboratory test results allowed the company to develop a product based on phenolic foam, SUPERCEL.
