They are designed to fit the majority of commercial wall applications between 450 and 600mm centered studs.
Polycoustic™ commercial batts (14kg/m3) are made from a blend of polyester fibres bonded with a low melt fibre to produce a 100% polyester insulation.
Polyester fibres are made from synthetic polymers known as polyethylene terephthalate (PET) - chemical substances found mainly in petroleum.
To reduce landfill, plastic drink bottles are recycled to produce a portion of the fibres used to manufacture polycoustic commercial batts. The strong fibres are soft to handle and the high density gives them the rigidity required to stand in a steel stud wall cavity, making for easy installation where an improved reduction in noise transfer between rooms is desired compared to the standard ISB range, while still using a polyester product.
