In the whole frequency to crash in the scope of the very good voice blocking effect, to most effectively isolated from the noise and air crash spread noise.

　　The foam is a kind of high density of foam, its penetration rate, aperture is made by the special design, can do sound insulation, shock absorption, waterproof,

　　Mouldproof, applicable to all kinds of moist environment. A kind of green environmental protection, the service life is more than 30 years. Simple construction, installation in the cutting tool cut,

　　No other tools,

　　Thickness of 11 mm, sum right standardization level improve quantity can crash of 22 decibels

　　Three layer compound structure, high density surface to prevent the construction process of the accident broken impact sound insulation effect

　　Internal full close pore structure make insulator has excellent waterproof performance, compressive strength, flexibility and resistance to chemicals performance

　　Is construction way:

　　1, when construction will be clean, and the sound insulation material cutting into the ground needed size.

　　2, meet, will support the ground sound insulation material cutting into the shape of the pillars, and take the hem up high of about 100 mm, meet wall also need the 100 mm.

　　3, material cohesion is fixed, with glue in material to build JieChu need 10-20 mm.

　　4, sound insulation materials in the ground above 5 cm of concrete filled after can.

　　5, in the concrete dry before please don't walk
