insulating coating insulating coating - DIATHONITE THERMACTIVE.037


  • Function:

    insulating, dehumidifying

  • Location:

    indoor, outdoor

  • Type of support:

    for walls

  • Component:

    lime-based, cork-based

  • Options:

    ecological, lightweight, fire, antibacterial


Thermal spray cork-based plaster for inside and outside, suitable for thermal insulation and dehumidification. Composed by natural raw materials, the product is suitable for historic refurbishment and green building.

Cork-based natural lightweight thermal coat (grain size 0 - 3 mm – 0 - 0.12 in), lightweight silica filler and natural volcanic materials with suitable grain-size distribution. Composed by natural hydraulic lime NHL 5, the product is antibacterial and prevents the development of moulds and condensation. Diathonite Thermactive.037 is ready to use, has good performances according to fire reaction, high porosity and breathability. Thermocoat performs heat and cold insulation, contributes to indoor thermo-hygrometric comfort and maintains its properties over time.
