Description
The pyramid panel is the most common model used to correct echoes and reverberation. Primarily recommended to absorb the energy of medium to high frequencies (500-4000Hz), thanks to the pyramid shape allows for both absorption and even reflection of sound waves. The pyramid sound-absorbing panel has a total height of 6 cm (2 cm base + 4 cm pyramid) with base width of 5 cm. Dimensions: The cutting of each sound absorbing product is paid the utmost attention but unfortunately polyurethane foam is a very elastic product that can move slightly during cutting. For this reason, even with the highest precision, all products can have a cut tolerance of +/- 2%. Fire reaction: Polyurethane products are not flammable but, like all plastic materials of an organic nature, they are combustible and burn in contact with the flame. Polyurethane in case of fire develops fumes and combustion gases whose composition varies depending on the characteristics of the foam (formulation, density, etc.) and the conditions of fire (ventilation, temperature, etc.). The most serious danger in the event of a fire is the development of carbon monoxide and oxygen removal from the environment. Testing shows that the composition of combustion gases developed by polyurethane foams does not generally differ from that of gases developed by products such as wood or wool.
