SONOclimat® is a rigid insulation panel that does not settle, is inert and retains all its properties over the years.

SONOclimat® is ideal for optimal energy-efficient constructions. The acoustical insulation panels are composite panels combining the performance of fibreboard panels with the expanded polystyrene (EPS)  type II  providing a thermal barrier that is efficient and continuous. 

SONOclimat® is distinguished by its superior physical properties and an excellent choice for your exterior wallsSonoclimatr4250x211 Other versions of SONOclimat® with different R values are available.
