Evidence of effectiveness and LNEC laboratory data
R'Acoustic 20 is a 20 mm thin acoustic insulation made from high-density recycled textile (90 kg/m³, mass per unit area 1.8 kg/m²) using the multi-layer process developed by Ceilingo. Its airborne sound reduction performance has been measured by LNEC (National Civil Engineering Laboratory of Lisbon) at Rw 50 dB in a 290 mm double brick partition configuration. To see where this product fits within the range and compare the three available thicknesses, please consult the Ceilingo range of acoustic and sound insulation products.

Case study: music studio
Our client, a drummer in a band, soundproofed his entire recording studio with R'Acoustic 20. The result speaks for itself: despite the power of a drum kit played at full volume, absolutely no sound escapes outside the building.

Quick installation on the ceiling
Watch an insulation professional fix R'Acoustic 20 directly onto a solid concrete ceiling using a pneumatic nailer. The installer uses an ingenious adaptation on his panel lifter to unroll the insulation easily from his ladder. Simple and effective installation, ideal for blocking noise between floors.

Everything you need to know about R'Acoustic 20
Five key questions about the R'Acoustic 20 thin sound insulation, with technical and legally binding answers.
What is the sound reduction index of R'Acoustic 20?
R'Acoustic 20 achieves a weighted sound reduction index Rw = 50 dB (C = −1; Ctr = −5), measured at LNEC (National Civil Engineering Laboratory in Lisbon) in accordance with standard NP EN 20140-3 and assessment EN ISO 717-1:1996. The measurement was carried out on a 290 mm wall comprising two 0.11 m hollow bricks, a 30 mm air gap and R'Acoustic 20 (20 mm, 1.8 kg/m²). Test report reference: 43/2008-LNEC/LEA, dated 21 July 2008.
On which substrates can R'Acoustic 20 be installed?
R'Acoustic 20 can be installed indoors on four types of substrate: walls (as acoustic lining for partitions or party walls), ceilings (under concrete slabs or wooden floors, fixed using a nail gun or staples), floors (as an underlay before screed or floating parquet) and roofs (as a roof underlay to treat airborne noise and improve the acoustic comfort of attics). Its surface mass of 1.8 kg/m² and compressive strength of over 2 t/m² enable it to retain its dimensional stability under load.
Is R'Acoustic 20 effective against impact noise?
The LNEC test for R'Acoustic 20 focuses on the attenuation of airborne noise (voices, television, music), for which the Rw performance of 50 dB is applicable in accordance with EN ISO 717-1. Impact noise (footsteps, impacts, objects falling onto the floor) is covered by a separate standard, EN ISO 717-2, and is not covered by the Rw measurement. For projects where the priority is comfort under a floating floor, Ceilingo offers the R'BULL Pro 5s, a 5 mm underlay for floating floors.
What is the composition of R'Acoustic 20?
R'Acoustic 20 is composed of high-density recycled textile fibres (wool, cotton and synthetic fibres) woven without glue using the multi-layer process developed by Ceilingo. Its high density of 90 kg/m³ activates the law of acoustic mass: the higher the density of a material, the more effectively it blocks airborne sound waves. This eco-design gives the product a reduced environmental impact compared to traditional synthetic insulation materials, whilst ensuring durability and dimensional stability over time.
Is an air gap required to achieve Rw 50 dB?
The Rw 50 dB rating is measured at LNEC on a double-skin wall incorporating a 30 mm air gap between the two brick facings. This air gap acts as a mechanical decoupler between the two faces and contributes directly to the system’s overall performance. The Rw 50 dB value therefore characterises the complete system (290 mm wall) and not the insulation alone. In a configuration without an air gap or on a single partition, the acoustic performance will differ. For precise sizing according to your project, contact Ceilingo technical support.
