Kingflex flexible sound absorbing insulation sheet is a kind of universal sound absorbing material with open cell structure, designed for different acoustic application. Kingflex coustic Insulation For HVAC Ducts,Air Handling Systems,Plant Rooms And Architectural AcousticsExcellent internal shock resistance. Extensive absorption and dispersion of external stresses in local positions. Avoid material cracking due to stress concentration Avoid the cracking of hard foamed material caused by impact. Reduces duct and plant room noise substantially Quick and easy installation - no bitumen, tissue paper or perforated sheet required Non-fibrous, no fibre migration Extremely high noise absorption per unit thickness Built-in ''''Microban'''' protection for product lifetime High density to dampen duct rattling & vibration Self extinguishing, does not drip and does not spread flames Fibre free super silent microbe resistant
