 COMPARATIVE RESULTS OF THE TEST
BETWEEN A SUSPENDED CEILING WITH AKUSTIK+SYLOMER
VS RUBBER SUSPENSIONS.
|
Table 2 compares the RA sound isolation index according
to the number of plasterboards.
The improvement is self-evident. the Akustik+sylomer®
mounts offer a superior isolation to the rubber mounts. This
difference is so great that it may be said that a ceiling
with a plasterboard with Akustik+sylomer® offers the same
isolation as a ceiling with two plasterboard rubber suspensions.
This therefore means savings in time and material. |

The savings in plasterboard and labour costs make these
mounts particularly interesting. both technically and economically.
In order to provide a better analysis of the differences between
the rubber mounts and the akustik+sylomer® mounts. table

| The results of these tables
show that the isolation differences are in the low frequency
range. which is particularly interesting for the isolation
of premises interesting for the isolation of premises particularly
difficult to isolate. |
