Polyvinyl chloride (PVC): PVC membranes are among the oldest single-plies still out there. If in contact with polystyrene insulation, the polystyrene will trigger the plasticizers within the membrane to leach out. To keep away from such membrane embrittlement, a separator sheet must be installed between the membrane and the polystyrene. To avoid membrane damage, a separator is also wanted to isolate PVC from asphalt and coal tar products. The ballasted attachment methodology isn't really useful as a result of advantageous dust particles from the ballast or particulate fall-out from the atmosphere could leach plasticizers from the membrane. PVC membranes can be found in a large number of colors and can even be printed with constructing names and logos. This membrane is generally selected for steep-slope roofs where a strong or unique color is desired. PVC is naturally a brittle materials and should be modified with plasticizers to be appropriate for roofing. Some early formulations of PVC suffered from plasticizer leaching out over time and experienced catastrophic failures. Choose PVC membranes which have been manufactured for many years to confirm their stability.
