WeldTite PVC Membrane
WeldTite Reinforced PVC membrane is a heat-weldable single-ply thermoplastic Poly (Vinyl Chloride) sheet designed for new roof construction and re-roofing applications. WeldTite PVC membrane is based on poly (vinyl chloride) resin in amounts greater than 90% of the total polymer content suitably compounded with plasticizers, stabilizers, pigments and other ingredients to exceed the physical property requirements and accelerated durability tests of ASTM D44341 Standard Specification for Poly(Vinyl Chloride) Sheet Roofing. The membrane is specifically formulated for long-term weather resistance with low volatility plasticizer and superior outdoor grade titanium dioxide pigment.
Physical properties of the membrane are enhanced by a strong, polyester fabric that is encapsulated between the PVC based top and bottom plies. The combination of the fabric and PVC plies provide WeldTite PVC reinforced membranes with high breaking strength, tearing strength and puncture resistance. The relatively smooth surface of WeldTite PVC membrane produces a total surface fusion weld that creates a consistent, watertight monolithic roof assembly.
CI’s WeldTite white PVC membranes are LEEDTM (Leadership in Energy and Environmental Design) compliant. The U.S. Green Building Council (USGBC) designed the LEED Green Building Rating System. White WeldTite is an ENERGY STAR® and California Title 24 rated roof product.
WeldTite Reinforced PVC membrane is available in highly reflective white 50-mil, 60-mil and 80-mil nominal thicknesses.
