Building acoustics cannot be separated from the use of low-inertia radiant systems. For this reason, RDZ, always attentive to the issues of footfall noise insulation, introduces two important novelties to be combined with its radiant systems: a desolidarising acoustic mat to be placed under the low inertia radiant system called ACU UPL-M, and a second acoustic mat to be placed under the cladding called ACU UT-M. The latter, in the case of undertile installation has a dual advantage: in addition to acoustically insulating the flooring, it drastically reduces the risk of cracking of the covering even in the presence of accidental screed breakage.







RDZ dehumidifiers are available in different wall or false ceiling models and allow the maximum efficiency of the system as well as a very high physical well-being to be obtained.
