PVC hollow sheet has good sound insulation effect: PVC hollow sheet can absorb noise or reduce noise passing through when it is affected by external noise such as rainstorm, hail, gale and so on.
Tough texture and high strength: another basic feature of PVC hollow sheet roof is that it must be able to withstand unexpected impact and cannot be damaged by natural external forces.
Volume stability: the PVC hollow sheet has low expansion coefficient and tensile property, which ensures that the geometric size of the tile remains unchanged even if the temperature changes greatly.
