The placostil partition and the top in acoustic and thermal insulation, for proof hospitals, cinemas and I
well else, are in placostil.
Partitions with metal frames offer a very wide range of possibilities,
current distribution partition, apartment partition, partition wall
high height, fire partition, acoustic partition and arched partitions.
They are therefore provided with the choice of qualities and regulatory requirements of
various plates BA6, BA13, BA15, BA18, BA25, doubled, tripled and various
powers, water-repellent plate, fire plate, high hardness plate

Adhesive foam tape for acoustics and waterproofing, is used for acoustic, thermal insulation and airtightness of partitions on metal frames (top and bottom rails and side uprights), allows to limit the propagate sound waves and dampen vibrations.
Brumat cinema
Reduce noise inside the house.
Provide insulating partitions between the parts
day and night parties. Take pipes
of water of a good diameter, use a reducer of
pressure, avoid sanitary appliances backed by
a partition of a room.

Acoustic partition
Do not confuse insulation and acoustic correction.
Acoustic correction ensures the clean acoustic quality of a room. This can be where listening must be encouraged (music room) or a place where the sound level must be reduced (entrance halls, circulation).
Do not try to pack the glass wool in the partitions because its sound resistance decreases when it is compressed.
Amount 48, 45mm wool and not 50, 60 ........
Cellular foams that are too rigid and certain too dense mineral wools should therefore be avoided for this use.
RECOMMENDATION FOR AN ACOUSTIC WALL.
A partition will have optimal acoustic performance if its design meets the Mass Spring Mass law.
The principle: two dissociated plaster walls, homogeneous and airtight, which sandwich a glass wool.
The fields of acoustics. Any sound phenomenon has three phases: the production, propagation and reception of sound.
Production is linked to the fact that a body, the sound source, begins to vibrate; acoustics therefore studies vibratory movements.
The propagation of sound from the source to the ear requires a material medium, gaseous, liquid or solid. So for the acoustics, always caulk well with the map on all the periphery; ceiling, partition etc.
Fire and acoustic partitions
Adhesive mortar map.
Glue and fill the holes
Goal Nimes
Caulk well with map on the entire periphery; ceiling, partition etc. ...
The partition is mounted first then the ceiling abuts against the partition at the desired height
For example, this technology (placostil) is used to make partitions in cinema complexes and in recording studios.
By varying the thickness of the plates (13,15 or 18mm) and especially their number, by integrating or not an insulation, we can achieve all levels of performance in terms of acoustics as well as thermal.
Examples of results obtained with distributive and separating partitions very commonly used.
Note: To obtain the desired sound insulation on site, partitions must generally have attenuation indices R greater than 5 to 8
dB to the desired result.

Placostil partition
Partition-lining connection
Running linings are likely to disturb the insulation between rooms. It is therefore advisable to interrupt them at the right of the partitions as soon as standardized acoustic insulation is sought.
The dividing walls between apartments must always be connected to the structural work.
The lining, whatever its nature, comes into abutment against the partition.
