THERMO-ACOUSTIC INSULATION

Acoustic or noise pollution is a form of widespread disturbance presently: in fact, human activities that produce loud noise have increased substantially over the years.

To improve comfort in living and working areas, when we use a premises it is important to limit the sound pressure inside.

Optimum acoustic reclamation is obtained through the use of sound-absorbent materials, sometimes in conjunction with soundproofing elements.

By acoustically isolating the walls of a building the passage of sound from the outside to the inside is totally or partially prevented; it is possible to achieve good soundproofing insulation through the installation of heavy materials such as: solid wood or high-density chipboard, steel or marble, which guarantee good sound insulation, or using deformable soundproofing materials such as lead sheets, rubber or glass.

In the case where the source of the noise disturbance is inside the building, it is possible to reduce the reverberation time, and then the reflection of sound waves on the walls and ceiling by using sound-absorbing coating materials directly inside the buildings; these are largely divided into two types, fibrous and those with open cells. Among the first are cork, fibreglass, rock wool and wood fibres; among the second plaster-based expanded perlite, polyurethane foam, exfoliated vermiculite, melamine foam and polyethylene. They reduce acoustic wave reverberation times in noisy places such as canteens, gyms, restaurants, schools etc., they increase user and worker comfort and the activities within them are therefore more enjoyable.

ADVANTAGES OF ACOUSTIC INSULATION

LIVING COMFORT

If the home is in an area with lots of traffic or in an industrialized area, residents greatly improve their quality of life.

WORKING COMFORT

Reducing noise pollution created in the workplace will improve the working conditions of the workers and not increase noise outside.

TAX SAVINGS

If soundproofing contributes to thermal insulation it is possible throughout 2015 to tax-deduct 65% of the expenditure incurred staggered over ten years thanks to government incentives for improving energy efficiency ratings, or equal to 50% over ten years in the case of building renovations.
