ACOUSTIK™ Rubber Flooring Underlayment

Recycled Rubber Flooring Underlay

Every step tells a story—but it shouldn’t be heard in the room below. Produced from recycled tire rubber, Acoustik™ creates a hidden layer of acoustic protection beneath finished floors, helping transform noisy buildings into quieter, more enjoyable environments. Its resilient construction absorbs footfall, vibration, and everyday impact noise while reducing sound transmission between rooms and floors. Unlike tree bark based underlayments that can compress and lose effectiveness over time, Acoustik™ is engineered for long-lasting performance, providing dependable sound control, added comfort underfoot, and enhanced thermal insulation. From bustling apartment buildings and hotels to offices, schools, and custom homes, Acoustik™ helps create spaces where conversations are clearer, distractions are fewer, and comfort begins from the ground up.
