K-Fonik 120/240 is a product that combines the features of thermal insulation and sound-absorbing material. The product has a flexible, open structure and is therefore so effective at absorbing acoustic energy. It serves as an independent layer or as a complementary layer on proper sound insulation, e.g. K-Fonik GK. This solution is used e.g. in the construction of machinery and equipment as well as in industrial pipelines.
