Hemp brick HESTIA INSULATION High
quality acoustic insulation
Grooves on bricks eliminate
acoustic & thermal bridges
The composition of
the Hestia blocks gives it an exceptional sound insulation quality, and
as they do not need to be covered for finishing by a plasterboard
(disastrous acoustic insulation) the
absorption of the inner sounds is maximum.
A single
wall in a room covered with Hestia bricks blatantly mitigates the
reverberation of sounds Construction of a recording
studio in Provence.
Comment from the engineer on the acoustic qualities of hemp
brick insulation: "Its own, a shiny hair, not
bad at all, very pleasant to work, and above all! unwanted low resonances ". Guy Roots: "I just
rediscovered my instructors in this isolated hemp brick studio. more angle effect, mate
without ever being deaf .. a good foot to take and mix the sound!" http://www.studiomatik.com/

Insulation of the 4 walls of a yoga room
I
am very happy to have these bricks, the participants of the yoga class
are also, happily surprised by the atmosphere
that emerges from the
room.we must also specify that hemp also has a good
thermal quality.With 20 cm
of cellular concrete and the 10 blocks of hemp, I
can get 17 ° without additional heating. Knowing that I
heat the room next to the
wood and the door remains open.That's always happy with the result and
one last thing,
the pose is easy and that's great.

walls of a rehearsal room, the hemp bricks of the ceiling are just placed on

corresponds to a totally reflective material
1 to a totally absorbent material
The sound absorption α is measured using
a device
called 'kundt tube', the density of the HESTIA block is too
low for the material to achieve a sound insulation
by mass
effect, it would rather tend to transmit the waves by
vibratory effect ,.
However, this
material has a
high open porosity, the emitted wave penetrates into the material and
amortizes along the capillaries by
viscous effects,
this explains these unique qualities of absorption of
waves.
