Acoustic Wall Insulation

The non-directional fibre orientation of ROCKWOOL stone wool effectively traps sound waves and reduces vibrations, preventing the passage of sound through its structure. When installed, this improves the acoustic performance of a wall.

Protection from unwanted noise can have a positive effect on our physiology, learning capacity and social behaviour¹. In offices and schools, reduced noise pollution can improve productivity. At home, better acoustics can also support improved sleep and general comfort.

It depends on the material. Thermal insulation and soundproofing are independent properties, but both are often linked to material density. ROCKWOOL stone wool insulation is effective from both a thermal and acoustic perspective.

Some acoustic insulation also delivers thermal performance. Before choosing which insulations products you want to use, it’s best to consider all of your requirements including thermal, acoustics and fire safety; and choose solutions which meet all of them.

R-value is a measure of thermal performance, rather than the soundproofing qualities of an insulation product. You might also see U-values, which are the reciprocal of R-values and also indicate thermal performance. For optimal indoor comfort, choose insulation solutions with a low U-value.

Different insulation materials offer different performance benefits, and it’s also important to remember that fire resilience may vary. Look for insulation solutions which offer thermal, acoustic and fire safety performance simultaneously to achieve against all of your requirements.
