Stone wool batt Roxul insulation excellent Sound-Absorbent in addition to it's thermal properties.
The unique non-directional structure of Rockwool stone wool content
is denser than traditional insulations. 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
Rockwool Roxul products as the density of the stone wool content is increased – such as
in our rigid and semi-rigid board products.
What is a good sound environment?
Noise should be dampened to such an extent that it no longer interferes with
the activity you were set out to do. Just 30 dB(A) is disturbing to sleep. Noise
with sound levels of 35 dB(A) or more interferes with the intelligibility of
speech in smaller rooms.
Even lower background levels are needed for adequate speech intelligibility
for vulnerable groups - such as the hearing impaired, the elderly, children in
the process of language and reading development, and individuals who are not
familiar with the spoken language
Rooms with many hard surfaces may result in disturbing ‘echo’ which must be
avoided. A reverberation time below 0.6 seconds is desirable, even in a quiet
A 10 dB difference is perceived by the human ear as a doubling (or halving)
of the audible sound.
A COMMON MISCONCEPTION
NOTE: AFB is NOT
the same as the residential batts called Roxul Safe 'n' Sound found in some
local home improvement stores. While they have similar uses Safe 'n' Sound is
geared toward very basic residential uses and is a less dense product (only
2.5lbs/cf compared to AFB's 2.8lbs/cf).

What does STC mean?
STC stands for Sound Transmission Class. This rating is used to compare the acoustic isolation of different materials. The method used to calculate the STC rating is ASTM E413.
What does NRC mean?
NRC stands for Noise Reduction Coefficient. The NRC of a material can be found by using either the Reverberation Room Method (ASTM C423) or the Impedance Tube Method (ASTM C384).
