DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing a process of attaching the PE composite nonwoven fabric to the ventilation panel in the sound insulation and ventilation panel of the present invention, Figure 2 is a cross-sectional view of the PE composite nonwoven fabric is attached to the ventilation panel in the sound insulation and ventilation panel of the present invention.

The sound insulation and ventilation panel of the present invention is formed in a plate shape as a whole, the ventilation panel 300 is provided with a plurality of panel cups 302 which are formed to protrude in the bottom spaced apart a predetermined interval; And a PE composite nonwoven fabric 100 integrally molded and joined to the upper or lower portion of the vent panel 300.

The vent panel 300 is formed in a plate shape as a whole, protruding from the lower portion is provided with a plurality of panel cups 302 are spaced apart a predetermined interval. The panel cup 302 serves to resist concrete lateral pressure due to the pouring of lightweight foamed concrete 420 or plastered mortar, and the space formed between adjacent panel cups 302 is used for water discharge and ventilation. It acts as a gout.

Therefore, as shown, it is preferable that the panel cup 302 has a circular cross section and has a cylindrical shape in consideration of structural mechanical properties and lamination convenience. However, for the convenience of manufacture, the cross-section of the panel cup 302 may be made into various shapes such as a triangle and a quadrangle. Since the noise generated from the upper portion of the inside of the panel cup 302 is rotated and extinguished, it is effective in blocking light impact sound and heavy impact sound. In addition, it is preferable that the diameter of the panel cup 302 is 0.5 to 1 cm when considering the ventilation performance.
