Acoustic well-being within buildings and homes is becoming an increasingly felt and widespread theme. Therefore, in recent years, numerous laboratory tests have been carried out to verify the optimization of acoustic insulation.
Sd Stampi, the leading company in Carpi specialized in polyurethane molds, reveals the test results.
Think of wild horns, sudden braking noises, shouting, screaming, voices, whistles. They are all noises that penetrate our home and that our ear perceives as annoying at the expense of our home comfort.
In Italy the issue of noise insulation is regulated by Law 447/1995 on noise pollution. There are also “passive acoustic requirements for buildings” to be respected during the design phase to comply with these standards.
When dealing with masonry structures and therefore, mostly heavy, the principle on which the insulating process is based is that the greater the mass of the structure, the higher the degree of acoustic insulation.
With regard to wooden structures (lighter) the principles become more complex.
Specifically, they are based on design choices that reduce the elastic properties of the structures in order to obtain significantly higher noise insulation.
Laboratory tests have shown that if rigid polyurethane foam panels are used, introducing them inside the layers that make up the structure, the rigidity of the structure increases with a decrease in the vibrational process and therefore with a net increase in the performance of soundproofing.
Polyurethane is considered one of the best acoustic insulators to guarantee the environmental comfort of buildings.
