A noise insulation system is provided to construct the noise insulation system conveniently by simplifying structure, and to cut down expenses by efficiently insulating impact and noise between floors. A noise insulation system(1) is composed of a first soundproof panel(10) made of expanded polypropylene, and a second soundproof panel(20) stacked and combined with the first soundproof panel and made of expanded polystyrene. An air chamber is installed between the first soundproof panel and the second soundproof panel to buffer noise, and formed by repeatedly forming lands(11) and grooves(13) in the second soundproof panel opposed to the first soundproof panel. A recessed pattern is formed in the second soundproof panel to buffer noise, and a check buffer pattern is recessed in the second soundproof panel and opposed to the first soundproof panel. A sealing member(30) is combined with edges of the first and second soundproof panels. |
