Ceresit Ceretherm Wool is a breathable and A2 class fire resistant  system with sound-proof properties. It offers high insulating performance while guaranteeing healthy living environment. Thanks to very high vapor permeability this insulation system is a perfect solution especially for all applications exposed to higher humidity and danger of biological contamination.


  • High vapour permability
  • Durability
  • BioProtect formula strengthened by high pH – high resistance to biological contamination
  • Flexibility and resistance to mechanical damage
  • Soundproof (mineral wool)
  • Natural – eco wool plates and silicate plaster
  • Very good working parameters

Recommended substrates

Wood skeleton walls with cement fibres boards, aerated concrete (dry) poorly ventilated, aerated concrete (wet) and silicate bricks

Especially recommended

Buildings located close to forests, buildings located in high air humidity areas, public buildings with high risk of biological contamination
