Acoustic Insulation - K-Flex

18
A unique and effective solution
for sound insulation of tubing.
Domestic and commercial buildings
(hotels, hospitals, etc...) have to
meet stringent requirements for
acoustic features.
A certified solution (by the
Fraunhofer laboratory) offers the
best approved result for specifiers
and general contractors.
Description
Ready-to-use system for acoustic
insulation of tubing.
K-FLEX K-FONIK ST GK
Fraunhofer institute certificate no. p-ba 247/2006
To assess the correct level of
soundproofing for waste pipes,
reference should be made to Italian
legislation DPCM 5/12/1997, and also
tests capable of simulating the true
operating conditions of the products,
as per the standards set by DIN EN
14366 and DIN 52219.
These tests enable the evaluation of
acoustic comfort in terms of LASmax
and LAeq (sound pressure level)
not just through R or Rw, typical
parameters for sound insulation of
walls, but are by no means exhaustive
for tubing applications.
Products not specifically tested for the
above parameters are therefore not
valid for use with waste pipes.
