SOUNDPROOFING MATERIAL FOR INTER LAYER NOISE PROOFING AND FLOOR FORMING METHOD FOR INTER LAYER NOISE PROOFING OF A CONSTRUCTION USING THE SAME

摘要

The present invention relates to an interlayer insulating material for noise reduction and, more particularly, open and closed cell member by laminating the insulating material to form a shell member, by forming a plurality of protrusions on one surface of the member to be closed cell air layer is further formed between the two members, the density of the insulating material and the sound and light weight sound generated by the air layer between the layers relates to a method for forming the floor of the building using the interlayer insulating material, and this anti-noise for noise protection for the interlayer to be blocked or reduced. ; wherein the insulating material is a closed cell member is a plurality of circular protrusions formed on a surface and; The open-cell circular projection member formed to be laminated on the surface of the closure shell member; characterized by made of a ; Thus, the present invention is a closed cell and a number of members of a circular projection formed on one surface, said circle By stacking the open cell by a projection member formed on a face to be an air layer is formed between the two members, the number of the air layer and by using this insulating material that can be cut off or reduce the impact sound transmission of such noise by the noise of the building block layers provides a method for forming a floor that has made possible.
