Soundsure 300 is an acoustic resilient layer that has been designed to isolate floor screeds from the main structure of the building, delivering superior impact and airborne sound performance.
Why Soundsure 300?
Soundsure 300 is a cost-effective solution for use below all types of floor screeds, where Pre-Completion Testing is preferred to that of Robust Details. As it is manufactured from recycled rubber crumb, Soundsure is not only extremely environmentally friendly, but also provides long-lasting durability and high levels of acoustic performance.
