PVC membranes are flexible sheets made from polyvinyl chloride, a type of plastic. They are commonly used in roofing and waterproofing applications due to their durability and resistance to weather elements. These membranes can be installed in various ways, including mechanically attached or fully adhered to the surface. In addition to roofing, PVC membranes are also utilized in other areas such as pond liners and geosynthetics. Their lightweight nature and ease of installation make them a popular choice for both commercial and residential projects. They are available in different thicknesses and colors to suit various needs.
