The National Construction Code (NCC) requests that all flooring products are tested to standard ISO 717 - 2 – Rating of sound insulation in buildings and of building elements. This measures the normalised weighted impact sound for floors, within Class 2 to 9 Buildings such as multi-residential applications.
The impact sound is the result of something impacting the floor and the resulting sound transmission through the floor into the rooms below. In accordance with ISO 717-2, the NCC sets a benchmark level of 62dB or less for vinyl floor coverings in commercial applications.
How is it measured?
When measuring the acoustic property of the floor covering, the ceiling construction and concrete slab thickness of the interior factor in to the impact sound result.
