The panelThe Bugnato sound absorber is a classic model used for basic correction of medium-high frequencies, in which high performance is not required. Suitable for the correction of study rooms, meeting rooms, etc. Dimensions: Maximum attention is paid to the cutting of each sound-absorbing product but unfortunately expanded polyurethane is a very elastic product, which can move slightly during cutting. For this reason, even with the highest precision, all products can have a cutting tolerance of +/- 2%. Reaction to fire: Polyurethane products are not flammable but, like all organic plastic materials, they are combustible and burn in contact with flame. In the event of a fire, polyurethane develops fumes and combustion gases whose composition varies depending on both the characteristics of the foam (formulation, density, etc.) and the fire conditions (ventilation, temperature, etc.). The most serious danger in the event of fire is represented, as for all organic compounds, by the development of carbon monoxide and the removal of oxygen from the environment. Experiments demonstrate that the composition of the combustion gases developed by polyurethane foams does not generally differ from that of the gases developed by products such as, for example, wood or wool.>
