5 mm Rubber Acoustic Underlay for Sound Reduction Flooring

5 mm Rubber acoustic underlay for Sound Reduction Flooring

ANIKA Acoustic ANK-700NC05 is a 5 mm acoustic floor underlay made from recycled rubber granules in China. It helps reduce the transmission of footfall and other impact noise to rooms below.

Installed as a continuous resilient layer within a compatible floor assembly, the rubber underlay helps limit the transfer of vibration from the walking surface to the supporting structure. It is supplied in 1 m × 11 m rolls for contractors, flooring distributors and project buyers.

Technical Specifications

Project performance depends on the slab or subfloor, floor build-up and installation details. Refer to the test report for the tested configuration.

Typical Applications

• Apartment and condominium floors where footfall noise is a concern.
• Hotel guest rooms and serviced apartments.
• Floating screeds and other compatible acoustic floor assemblies.
