‘Our heavy acoustic foam HEAVY Duty Tec with its high mass is suitable for noise insulation and structure-borne sound insulation in the technical area. Apart from standardised sound insulation panels, we also offer the production of special shapes. This is particularly interesting for use on machines. As a result of the practical self-adhesive kit, the absorber can be installed easily, even in difficult positions.’
