Materials & Applications


Acousticork Underscreed

High impact sound insulation in flooring screed application.

Acousticork underscreeds range offers the right product for medium to high acoustic demands. The product properties and profiling of the Acousticork floor mats are specially designed for high and variable loads.

Acousticork underscreeds are a high performance solution to insulate new buildings. These floor mats are specially designed even for high loads with low deflection. Because of this, their use can be extended to multi-use buildings (hotels, refurbishments, assembly rooms, shopping centers, supermarkets, etc.) with a stable material properties over the entire service life.

  • Improving comfort with sustainable solutions

    Outstanding impact noise insulation, Acousticork underscreed improves the quality of living and working environments. The range offers resilient layers made of natural and recycled materials that provide a low level of compressibility, reduce crack formation in the screed, and the resulting costs.


    With Acousticork underscreeds, the final costumer can be sure that the building will have fewer vibrations and less noise; less airborne, structure-borne, and footfall noise and the building will offer a better quality of life or improved working conditions.

Acousticork Underscreed U36

U36 takes sustainability and the focus on the circular economy to another level. It is made of cork, a natural and reusable raw material, with post-production circular economy materials and no rubber, to address one of the most critical problems today: noise.

Key Features

Sustainable materials with a performance capable of solving all noise-related issues

Acoustics is one of the most important criteria when it comes to insulation, as noise might be a discomfort factor in buildings. Noise easily spreads throughout buildings using its’ elements as sound transmitters. The solution found to reduce noise impact and improve thermal insulation properties is decoupling the elements by incorporating resilient materials such as underscreeds.

The nature of the application and technical specifications may require different types of materials. Within our range of underscreeds you might find a variety of sustainable materials with a performance capable of solving all noise-related issues.
