SYLWOOD - Sound Insulation Underlay for Wooden Floors

SYLWOOD is an advanced floor sound isolation underlay developed to elevate the performance of wooden floors by reducing structural and impact noise. Beneath its slim 3 mm profile lies a carefully engineered blend of dense rubber and natural cork granules, materials chosen for their ability to absorb vibration and limit sound transmission through the structure.

SYLWOOD is different from conventional foam underlays. It offers real sound insulation and lasting stability. It creates a flexible yet firm layer that separates the floor finish from the base structure, stopping noise from travelling between rooms while preserving the authentic feel of natural wood. 

How It Works

SYLWOOD’s high-density rubber base absorbs vibration energy before it transfers through the structure, while the integrated cork granules improve elasticity and natural damping. The result is a durable, thin, and eco-conscious layer that softens the sharp sound of footsteps and makes interior spaces quieter and more pleasant.

This product is engineered for both new and renovation projects, meeting modern acoustic requirements and providing long-lasting sound insulation for residential, commercial, and office applications.
