PVC corrugated waterproof sheet is made of high-quality single-layer thick mineral plant fiberboard impregnated with asphalt under high temperature and pressure. It has high compressive strength and excellent waterproofing performance because it is formed at high temperature. Its service life is as long as 70 years. It promises 25 years of quality assurance.
As the underlying layer of various tile materials, PVC corrugated waterproof sheet really plays the role of waterproof, ventilation, heat insulation and dehumidification. Because the permeable layer structure formed by this material is very simple, and PVC corrugated waterproof sheet is easy to cooperate with other insulation materials and roof tiles, which not only reduces the total cost of roof engineering, but also makes construction simpler, so the quality of roof engineering is more assured.
