Why choose Elitexa flame-retardant soundproofing foam?

Density and performance

Most conventional sound-absorbing foams have a density of only around 20 kg/m³. Elitexa’s ten-times higher density (200 kg/m³) provides real sound blocking and sound absorption, not just echo reduction.

Low-frequency performance

While standard foams are mainly effective above 1000 Hz, Elitexa absorbs sound from as low as 40 Hz. This is especially important for:

• studios

• home cinemas

• mechanical noise

• bass-dominant environments

Structural advantage

Its dense, grid-like internal structure does not allow sound waves to pass through easily. Instead, it absorbs and dampens a significant portion of the sound energy, functioning as a true soundproofing layer.

To further improve both aesthetics and soundproofing performance, we recommend combining the product with Bilnora felt panels. This achieves even better sound insulation while saving on professional installation and additional material costs, as the system can be installed independently at home.

These properties make Elitexa sponge particularly suitable for situations where precise sound reproduction and effective sound isolation are essential. Whether in a studio, a home cinema or even a public space, Elitexa sponge is an excellent choice for creating the desired acoustic environment. To further improve the aesthetic and sound insulation aspects, we recommend combining the product with Bilnora felt panels to achieve an even better sound insulation effect. You can also save on the cost of professional labour and additional material costs.

Applications

Wall, ceiling, behind drywall

• built into drywall partition systems

• glued directly to walls, can be wallpapered or skim-coated

• ceiling sound insulation

Underfloor use

• under parquet flooring

• suitable as laminate underlay and carpet underlay

• reduces impact and footstep noise

Thanks to its high density, it does not compress and provides a stable walking surface.
