Thermal and acoustic insulation, waterproofing and coatings for building sector.

Sassoferrato, Ancona




Diasen is an international company that has been designing, developing and producing sustainable construction materials for over 25 years to waterproof, isolate and restore any type of surface.

Diasen, always focusing on the environment, the development of the territory and the well-being of people, has decided to become a Certified B Corporation as this type of environmental certification is full agreement with the company's mission.

The certification process for Diasen was the occasion to measure the company's performance from another point of view, that of environmental sustainability, the development of local realities, and employee welfare.

The Environment is life, home and habitat. It is also the source of all our materials. Water, Earth, Wind and Fire, the four natural elements are at the base of the production process at Diasen: in fact from Nature we source all the raw materials of our products, and during the manufacturing processes we aim to maintain and highlight their characteristics. Our products are designed to improve the conditions of life in the environment closer to people: their homes. The aim is to protect them from high levels of humidity and thermal losses, using the same methods adopted in Nature. Respect for the environment is our duty, and this is reflected in the standards that we follow to improve our processes, products and relationships with employees, clients, suppliers and the territory where we work.

What makes us a better company?
