Noise proof raised access floor Teknofloor srl
TK SOFT

The TK SOFT solution is the only patented system with certified performance which drastically reduces the impact noise transmitted from one floor to another.
Our solution means that noise levels considerably lower than those required by law can be achieved thus combining the advantages of a raised floor system with those of noise insulation: another Teknofloor® breakthrough.

In Italy legislation on permissible noise levels states that in this field the framework law no.447 dated 26 October 1995 applies. This law establishes the sphere of jurisdiction of the State, Regional authorities, Provincial authorities and Municipalities, introducing plans for acoustic remediation and supplying dispositions on the matter of acoustic impact.Law no. 447 "Passive acoustic requisites for buildings" Ministerial Decree 5/12/1997 indicates the maximum limits for the level of impact noise transmitted (L'nw):

Type of building
L'nwResidential, Hotels 63 dB
Hospitals, nursing homes, schools 58 dB
Offices, places of worship, commercial premises 55 dB

The law lays down that the impact noise perceived one floor away must not exceed a certain level. It is therefore clear how important the observance of such requisite is, both to avoid economic damage and to guarantee maximum comfort to the future occupants.For example, in the case of offices, with a floor 20 + 4 cm high in a clay /cement mix (300 kg/m2) a foreseen noise level of 77 dB is established: our system permits a reduction of 33-35 dB, to achieve a transmitted value of approximately 42-44 dB: absolutely superior performance compared to traditional systems.
