Product information
This is a sheet to reduce the sound of rain by lining a metal roof with it. The mechanical energy generated by vibration is converted into the the kinetic energy generated by high molecules in the sheet, thanks to which, the product can absorb sound makes it possible for the product to absorb sound. It is made of polyolefin resin whose sound-absorbing effect is much better than that of conventional materials such as rubber and vinyl chloride.
Features
①Reduces the sound of rain by attaching the sheet to the back of metal sheets.
②Durable enough to be used for a long time.
③Easily installation thanks to adhesive backing.
④Greater performance compared with conventional materials including rubber and vinyl chloride.
⑤Starts to absorb sound and vibration as long as it is applied to about 30% of the total area of the front side of an object.
