RFU Data Sheet

RFU is a certified underlay system that has been internationally tested and proved to be the first in its kind to meet the requirements of the Building Regulations. RFU has been tested on a concrete as well as on a wooden substrate.

The results showed an outstanding reduction of impact sound of 22 dB Δ Lw / 10 dB ΔLlin in combination with laminate as from 7 mm thick, according
to BS-EN-ISO 140-8 / 717-2. This improvement has been obtained on a concrete base floor with an affixed screed*.

With this result RFU is not only the ideal underlay system for parquet and laminate, it also guarantees a longer lifespan of both flooring types. RFU is fitted with a special VVP-layer that makes sure that while cutting, no fibers are separated from the panels. It also contributes to the outstanding sound reducing qualities.

RFU is made out of pure natural wood leavings from pine trees and can therefore be fully made into compost. The RFU panels have a natural color and provide, besides the already mentioned sound reduction, a perfect thermal insulation as well, and it provides outstanding leveling qualities of up to 3 mm for every kind of substrate.
