Soundproofing is any means used in order to reduce the transmission of energy from the source to the receptor places, which have to be protected.

    The normal threshold of hearing for humans is 0 decibels; a sound of 120 decibels causes irritation; if the sounds gets close to 140 decibels, there is a pain feeling. 

    The aim of soundproofing is therefore to protect people from noises, lessening or eliminating the perception, through a dispersion of the sound energy.

    Although interior doors were conceived to separate different areas of the same, macro space, the results obtained by the doors of the Pivato's collections during the tests performed according to the reference norm UNI EN ISO 10140-2:2010, stated a soundproofing value between 28 and 30 decibels, thus proving that Pivato cares and is concerned about this question.

    Formaldehyde is an organic gassy compound which was often used in the past as bactericide. Nowadays, formaldehyde is considered one of the most common interior contaminants. It can cause irritations to the eyes and the respiratory system; its carcinogenicity was confirmed by AIRC (Italian Association for Cancer Research) in 2004.

    In the wood industry, formaldehyde is used in the production of resins employed for the preparation of ureic lacquers, adhesives and papers impregnated for the nobilitation. However, the main use of these resins is in the production of MDF boards or plywood. Also for this reason, Pivato has always been using only fir or poplar semi-finished products for its doors.

    As regards the emissions in the housing, the law establishes a maximum limit of 3,5 mg/m2h. During the tests performed by CATAS institute, Pivato products proved to release an average value of 1,25 mg/m2h (the variability depends on the finish of the door), thus amply remaining under the established limit.
