With interior insulation, it is important that there are no cavities on the cold side of the thermal insulation and that the construction is airtight. The soft insulating wool in the ISOnatura® construction nestles seamlessly even on uneven surfaces, effectively preventing convection currents in the critical zone. Rockwool is mineral, so it cannot mold, rot or rot.
The mineral and vapour-permeable gypsum carrier boards with tongue and groove are glued airtight and filled with gypsum. Optional for critical substrates: A vapor barrier ensures additional safety.
