3 Acoustic insulation - Intro U-Boot Silence - The solution In recent years the awareness of home comfort has become increasingly widespread. Developers and end users require outstanding performance and quality characteristics, appropriate to their expectations and demand specific warranties from the manufacturer and the designer. While on the subject of energy saving leaps and bounds have been made in recent years, the problem of acoustic comfort is still underestimated. Recent studies have also shown that people who live in areas not adequately insulated acoustically have trouble sleeping, irritability, reduced productivity at work. For these reasons, non-compliance with minimum noise insulation performance may compromise the very validity of the certificate of habitability and produce a considerable loss of property value. The noise in buildings, depending on its origin, is classified as: - airborne (it propagates through the air, such as radio, TV, shouting between people); - by impact (it propagates through structures such as shock, stamping, machinery vibration, falling objects, etc..) - by technical installations (drains, burners, air conditioners, fans). The D.P.C.M. 05/12/97 has introduced a classification of residential areas (Table A) which has fixed the passive acoustic requirements for buildings, their components and technological systems with the purpose to reduce human exposure to noise and thus improve the conditions of acoustic comfort (Table B). The UNI 11367:2010 "Acoustics in buildings - Rating of sound housing units - assessment and verification procedure in place" standard establishes, on the other hand, the procedure for assessment and verification in place of sound insulation of buildings and sets, similarly to what happens for the energy needs, a classification on the basis of their performance at the sound reduction level (Table C). U-Boot Silence is the sound insulation mantle specifically designed to be used on slabs lightened with the U-Boot Beton® system, which "silences" for good the annoying airborne noise and by impact. The application of U-Boot Silence on these lightened slabs delivers excellent insulation performance by placing the building into Class I (UNI 11367:2010) for the airborne noise and impact.
