Sound-Absorbent
The unique non-directional structure of Roxul Insulation stone wool
content is denser than traditional insulation's. This effectively reduces
airflow and essentially, sound transmissions. Higher air flow
resistivity means better sound attenuation. Excellent overall sound
control is further achieved with several Roxul products as the density
of the stone wool content is increased – such as in our rigid and
semi-rigid board products.
What happens if Roxul
stone wool gets wet?
Roxul stone wool insulation is moisture resistant yet vapor
permeable. In the event the insulation becomes damp or wet,
the insulation, when thoroughly dried, will maintain the
original performance characteristics.
Are Roxul stone wool products mold resistant?
Roxul products are inorganic which provide no food source
for mold to grow. Roxul products are tested to ASTM C1338 –
Standard Test for Determining Fungi Resistance – and pass
with zero fungal growth.
Can Roxul stone wool
insulation soundproof my
walls or ceilings?
Roxul stone wool insulation products can help to reduce airborne sound within
your home when installed in both walls and ceilings.
Possible sources of sound transfer can occur between
adjoining floors, walls, ceilings and through electrical
receptacles and furnace vents. Most sound in the home is
airborne sound generated by music, voices, ambient noise,
etc. Impact sound is the result of foot traffic or falling
objects. If reducing impact sound is the primary concern,
additional measures such as the addition of resilient
channels or a sound absorbing layer between the sub floor
and the joists are recommended. If you require a specific
STC (Sound Transmission Class) Rating then you can call
