Diathonite Evolution is a 100% ecological material, made of Mediterranean raw materials, such as cork, diatomaceous earth, natural hydraulic lime NHL 3.5, clay and fibers.

It ensures a perfect thermal insulation, against cold and heat, for this reason it is a solution which ensures a total protection everyday of the year: its low thermal conductivity of 0.045 W/mK does not change over time and its composition turns it into a perfect anti-moisture material: its porosity and its high breathability absorb the rising dampness and release it out of the walls. At the same time, thanks to cork, it remains warm throught time, reducing the energy consumptions during Winter and Summer as well, improving the thermal comfort.

Furthermore, the material owns good values of sound insulation and acoustic absorption, for this reason it is a solution which can resolve many different problems by using only one product.

Diathonite Evolution perfectly represent our philosophy of Mediterranean Building and Architecture, resuming construction techniques of the past and materials of typically Mediterranean origin, transforming them into advanced solutions for the future of construction.

Key benefits

  • Perfect insulation against cold and heat
  • Highly breathable
  • Reaction to fire: Euroclass A1
  • Ecological material
  • Extemely quick application system (it can be spray-applied by plastering machines)
  • Homogeneous correction of thermal bridges
  • It is a real evolution for the building, being a combination of thermal insulation, sound absorption and dehumidification
  • It can be recycled at the end of its life cycle
