Cork is a naturally dense, resilient material — its cellular structure compresses under load and recovers, absorbing the energy of footfall and impact before it can travel through the floor structure. At 600kg\/m³ density, SilentCork3 provides meaningful mass and compliance in a thin profile that does not raise floor heights or conflict with door clearances.\u003c\/p\u003e\n\u003cp\u003eEach roll covers 15m² at 3mm nominal thickness and is suitable for bonded and loose-laid LVT, laminate, and wood floor finishes. The product is compatible with underfloor heating systems and is designed to be adhered to concrete and screed subfloors using a suitable contact adhesive. Tested acoustic results vary by floor finish: 17dB reduction with click LVT, 18dB with glue-down LVT, 20dB with sheet vinyl, and 33dB with carpet tiles.\u003c\/p\u003e\n\u003cp style=\"margin: 16px
