Sound Absorption Insulation
The unique non-directional structure of ROXUL Insulation stone wool content is denser than traditional insulations. This effectively reduces airflow and essentially, sound transmissions.
A natural sound barrier
It’s the open, porous structure of stone wool that makes it highly efficient in protecting against noise pollution. In ceilings, noise screens, around noisy machines, in walls, roofs and floors and even underneath rail tracks, ROCKWOOL insulation acts as a natural and effective sound barrier. ROCKWOOL insulation is the number one acoustic solution when soundproofing buildings.

The Cogeco Amphitheatre is an award winning new outdoor auditorium located in Trois-Rivières Quebec. The project is the result of an open anonymous architectural competition won by Atelier Paul Laurendeau in 2011 to endow the city with a new public infrastructure to host summer shows and festivals.
ROXUL is designed to reduce sound attenuation through the wall which is the process of reducing the sound energy through the wall. Sound proofing is the process of keeping sound contained in a space preventing the sound moving from one part of the building to another. ROXUL AFB®, SAFE’n’SOUND®, CAVITYROCK®, COMFORTBOARD® 80/110, CURTAINROCK®, SAFE®, and ROCKBOARD® all provide sound attenuating properties. Please see product technical data sheets for specific information.
Sound “loudness” is measured in decibels [dB]. Sound frequency is the number of vibrations caused by the sound per unit time. The amount of sound decreased is expressed as an STC rating which is a measure of a material’s or an assembly’s ability to resist sound transfer. The higher the STC rating the more noise is blocked from transmitting through a wall or material. The decibel reduction of a wall that has an STC rating of 50 depends on the frequency of the sound. At a high frequency [baby crying, church bells] there may be a reduction between 40 – 50 dB while at a low frequency [bass drum] there may be a reduction of 10 – 15 dB.
Looking at a perfectly insulated structure which would affect mid-high frequency sound, when compared to fibre glass, ROXUL insulation provides a difference of 3 – 7 dB. However, differences in the installation between products can make an impact on the sound attenuation.
