It is the most frequently used sound insulation product as its high density sound barrier provides high efficiency with low thickness. The most efficient sound insulation is provided when used with soft and porous sponges. It is recommended to be used together with Bondexpan or sponge pan. Non-felt PVC barriers cannot be laminated, so they are often used for floor sound insulation or between two plasterboards.
The thickness of the PVC sound barrier, sold in 1x10mt rolls, varies between 2-5mm. It does not have fireproof properties and is only black in color.
