1mm Thick Medium Density PVC Foam

This kind of PVC foam can be used for sound insulation of PVC floors.

PVC foam is a type of closed-cell foam that is often used as a soundproofing underlayment for PVC flooring. It is made of polyvinyl chloride (PVC), a versatile plastic that is known for its durability, water resistance, and affordability.

Soundproofing is the ability of a material to reduce the transmission of sound. PVC foam is a good soundproofing material because it is dense and has a high closed-cell content. This means that it is able to absorb and trap sound waves, preventing them from traveling through the floor.
