Phenolic insulation board is not only insulation, sound absorption and sound insulation effect is very good also
in fact, the optical properties of phenolic insulation board and phenolic insulation board sound-absorbing function can use phenolic insulation board, light wall of sound insulation system is the outer walls of buildings. Traditional phenolic board not only can be used for exterior insulation system, can be also prepared to act the role of surface composite insulation decoration plate, can also be used to build the traditional EPS/XPS/fire belt, PU external wall insulation system will be used for fire prevention in the curtain wall insulation insulation materials, fire door insulation materials, as well as low or high temperature fire insulation thermal insulation material. External wall insulation system of typical structure to a + + + keel phenolic board plasterboard plasterboard. Sound insulation effect is the main phenolic insulation board, it absorbs part of the sound waves through the plasterboard, reduce the sound waves in the cavities formed between the plasterboard, keel and gypsum board of reflection. In order to achieve increased wall sound insulation function. By the professional test instrument, adding phenolic insulation board in the external wall insulation system of exterior wall sound insulation effect is higher than without phenolic insulation board of plasterboard 8 ~ 15 db.
should be paid attention to, phenolic insulation board in the construction process of easily crushed due to improper operation or cracking. In the external wall insulation system, therefore, should pay attention to the construction technique of phenolic insulation board, in addition, because of the characteristic of the phenolic foam, usually buy phenolic insulation board often occurs pulverization and embrittlement phenomenon. But the only way to solve this problem is to buy a fairly thick phenolic insulation board. Phenolic plate thickness, however, it is easy to fall off, because phenolic board quality is more important in the external wall insulation system, therefore in the construction of exterior wall insulation system, should pay special attention to the thickness of the phenolic insulation board and construction process.
