Acoustic Insulation for Floors and Walls
URSA Acoustic Roll is suitable as an acoustic absorbing material in separating and partition walls and floors (ceilings).
URSA Acoustic Roll - thermal conductivity 0.035 W/mK.
Density 22 kg/m³ (except 100mm minimum 12 kg/m³).
Sound insulation is required to prevent noise (unwanted sound) being transmitted from room to room within a building or from external sources. The transmission of noise within a building is by two main routes; airborne and impact. This may be further complicated by 'flanking' transmission, an indirect route through adjacent walls, floors and ceilings.
The four governing factors of acoustic insulation are;
The acoustic performance of any element depends to a large extent on detailing and workmanship. The following points must always be considered;
The sound absorption coefficient, as, of 100mm URSA Acoustic Roll measured in accordance with BS EN ISO 354 is as follows:
