The
acoustic comfort in
individual rooms of the house, to a large extent, corresponds to the material
from which the internal walls will be built. We
advise you on how to make the walls inside your home so that they become good
guardians of sounds
The
acoustic insulation of internal walls of the house is also important as
external walls. It
will depend on the comfort of the household members staying in individual
interiors. In
order for the noise coming from behind the wall not to hinder their rest, work
or sleep, it is worth considering the choice of materials for internal walls. The
acoustic insulation of internal walls, from airborne sounds, is determined by
the R'A1 index. According
to the standard, in the basic standard, the value of the R'A1 index for
internal walls, between rooms, should not be less than 30 dB. In
the case of walls between rooms and the kitchen or bathroom, it must be higher
and be 35 dB. If
we want an increased acoustic standard, this indicator should be at least 40
dB.
Quiet
brick walls
As
far as the internal load-bearing walls are concerned, we should not have a
problem with their sound insulation, as it is usually guaranteed by the large
mass of these divisions. In
the case of partition walls, more attention should be paid to their thickness
and choice of materials. The
proper acoustics will be ensured by solid bricks or silicate-lime blocks. It's
good that the wall made of them should be 8-10
cm thick. In
order to achieve even higher acoustic insulation of internal walls, it is worth
choosing a thicker partition (eg 14
cm) - especially if it is to separate from a room more exposed
to noise, such as a bathroom or a small music room. The
impact on the acoustic insulation of partition walls has also a way to finish
them. Traditional
plasters - for example cement-lime plasters - work best here.
Quiet
partitions with a lightweight skeleton construction
A
partition wall with a frame structure, although it is relatively light, if it
is properly made, it can effectively suppress annoying sounds. Before
installing the perimeter profiles, fixed to the walls, floor and ceiling, they should
be secured from the bottom by sticking the acoustic tape. It
prevents the transmission of sounds from other partitions adjacent to the
partition wall. In
order to improve the acoustic insulation of the lightweight wall by about 8 dB,
instead of lining of single plasterboards, it is worth using two layers. Another
solution is the use of plasterboards type F - with increased fire resistance. They
are distinguished by a higher weight than standard A-type boards, which
improves the insulation of the partition.
In
order for the partition wall, with a frame structure, to isolate well against
noise, the space between the panel cladding should be filled with mineral wool. It
is recommended that the thickness of the wool be slightly smaller than the
width of the profiles so that it does not touch the liner.
