Isocheck weight-enhanced Barrier Mat acoustic flooring systems are primarily used to enhance airborne sound. Their low-frequency damping properties are frequently utilised to improve floors and walls that have been found to fall short of an airborne sound test. Isocheck weight-enhanced Barrier Mat 5 (2 - 3mm) is constructed of high-density barium sulphate loaded thermoplastic polymer, plasticised with phthalate esters and containing mineral fillers. They are black (in colour), bitumen free, ecologically neutral and recyclable. .
