Phenolic insulation board is not heat preservation, sound absorption and sound insulation effect is very good also _ langfang three friends of insulation materials co. , LTD
because of high quality heat preservation effect of phenolic insulation board, by many users and phenolic insulation board, sound absorption and sound insulation effect is little people talk about actually phenolic insulation board is not heat preservation, sound absorption and sound insulation effect is very good also.
phenolic insulation board is the main raw materials of phenolic foam, and phenolic foam is a kind of very good sound insulation, sound-absorbing materials so phenolic insulation board not only has the characteristics of light weight, small coefficient of thermal conductivity, non-combustible also have very good sound absorption and sound insulation effect, and coefficient of phenolic insulation board of national standard of phenolic insulation board with clear requirement and defined, which is why phenolic insulation board can be as the sound-absorbing material is widely used in building external wall insulation system. Phenolic insulation board in the working principle of external wall insulation system is what?
in fact light properties of phenolic insulation board and phenolic insulation board sound-absorbing function make phenolic insulation board can be used for light wall of sound insulation, that is, building external wall insulation system. The typical structure of external wall insulation system is keel plasterboard + + phenolic board + gypsum board. Mainly is with the function of sound insulation in the sound-absorbing phenolic insulation board, it absorbs part of the sound waves through the plasterboard, reduce the sound waves in a cavity formed between the plasterboard, keel, gypsum board of bounces back and forth, so as to enhance the role of the wall between the volume. Through professional equipment testing after adding phenolic insulation board exterior insulation system of exterior wall sound insulation effect is better than only use plasterboard not adding phenolic insulation board insulation results improve ~ decibels.
it is important to note phenolic insulation board easy in construction process due to the improper operation crush or cracked. Therefore phenolic insulation board need to be paid attention to in the construction technology of exterior insulation system, besides regular buy phenolic insulation board often occurs due to the nature of the phenolic foam pulverization, embrittlement, but the only way to solve this phenomenon is to buy a phenolic insulation board thickness, the thickness of a phenolic plate due to its quality is on the external wall insulation system is easy to fall off, so be especially careful when in building external wall insulation system of phenolic insulation board thickness and construction technology.
