RESILIENT HIGH PERFORMANCE UNDERSCREED MEMBRANE MADE OF RECYCLED POLYMERS
SILENT FLOOR PUR
SILENT FLOOR PUR is the highest performing sound insulation in the SILENT FLOOR family. Properly applied in the underscreed, the product increases the acoustic performance of the finished floor. It is also an excellent supplementary solution for impact noise and floor soundproofing of timber, steel or masonry structures.
APPLICATIONS
- Combined with resilient profiles, it solves the problem of structure-borne noise
- Underscreed application makes it effective against impact noise and provides excellent soundproofing
- Also suitable for the renovation of vertical partitions, it works as acoustic insulation applied to supporting walls
Thanks to the special polyurethane compound, it offers excellent elasticity and achieves impact noise attenuation values of over 30 dB.
SILENT FLOOR PUR: high soundproofing.
Added to its excellent soundproofing performance, SILENT FLOOR PUR is a sustainable product because it consists of polyurethane derived from production waste. It is recycled and recyclable.
As a noble polymer, polyurethane maintains elasticity over time without subsidence or changes in performance, ensuring product durability.
SILENT FLOOR PUR is made combining a waterproof membrane with a resilient component obtained from recycling latex and foam rubber. Its effectiveness as a sound-absorbing and insulating material has been approved in the laboratories of the Industrial Research Centre of the University of Bologna and the Building Envelope Lab of the Free University of Bolzano.
It does not contain substances harmful for people and the environment.

Specifications
Supply and installation of resilient high performance underscreed foil made of recycled polymers, type SILENT FLOOR EVO
Composition:
- Waterproof membrane coupled with a resilient component made from recycled latex and foam rubber. Does not contain harmful substances. Tested and certified by the Industrial Research Center of the University of Bologna
Properties:
- Dynamic stiffness s’ [MN/m³] : 11
- Creep : ≤ 0,7
- Theoretical estimate of the degree of impact sound attenuation ∆L [dB] : 33,5
- System resonance frequency f0 [Hz] : 47,5
- Compression deformation stress [kPa] : 17
- Thickness [mm] : 10
Suitable for timber-to-timber installation to create a physical and mechanical separation between the two elements, thus avoiding the transmission of vibrations caused by impact sound. To increase the vibration absorption capacity, it is advisable to install the profile both below and above the timber floor. Install the profile on the upper section of the wall and fix it mechanically with staples every 40/60 cm. Then install the horizontal panel of the floor and repeat the operation.
