Coccioterm MGN is a thermal insulating plaster based on lime, natural perlite and traditional cocciopesto (brick powder) with excellent insulating and sound-absorbing properties, and good mechanical resistance. 

It is based on the ancient concept that the porosity of the lime and crushed terracotta give the product a high vapor permeability and an exceptional ability to regulate the humidity present in the masonry.

Coccioterm improves the comfort of your building because:

  • It improves the thermal performance of the building, keeping the walls warm and dry.
  • Due its outstanding thermal insulation saves energy and heating costs.
  • Thanks to the thermal capacity and thermal inertia of the brick dust (terracotta) and natural perlite (a fluffy volcanic material) cocciopesto plasters function as an energy reservoir: even out temperature oscillations, improving overall thermal comfort.
  • The natural hygroscopicity of the fired brick powder combined with the natural porosity of lime regulates the humidity of the internal environment by acting as a hygrometric buffer.
  • It is a highly breathable plaster that prevents the formation of mould due to moisture stagnation.

Why Cocciopesto?

Milled terracotta or brick (in Italian: cocciopesto) was used in antiquity for their well-known thermal and hygrothermic properties. 

Earthenware plasters have been used extensively in Roman heating plants due to their ability to accumulate heat and absorb the moisture from hot flue gases.

Cocciopesto plasters have been in use since about 500 B.C., traditionally made of pure slaked lime mixed with crushed tile or brick powder. Initially a Phoenician plaster adopted by the Romans, it has been widely used in the construction of aqueducts, Roman baths, roads and underfloor areas. They can be found in a lot of archaeological areas and historic buildings throughout Europe as the Romans have "exported" and used cocciopesto plasters throughout the former Roman Empire.
