Anti-UV Waterproof Tensile Membrane Structure for Roofing Parking Lot Architecture

PVC Tarps, or polyvinyl chloride tarpaulin, is available as a woven or non-woven material, and has been a staple in the fabric membrane roofing industry since the early 1960s.

PVC membrane is a cost-effective alternative to traditional roofing systems and can be produced in a multitude of colors to coordinate with individual building project needs. When produced in bright white, this flexible fabric membrane reduces radiant heat gain, keeping interior temperatures cooler during warmer weather conditions.

PVC membrane is commonly coated with a protective acrylic or PVDF top coat with a design life of approximately 15-20 years. If PVC membrane is exposed to high levels of UV in such areas like Florida or in the Southwest U.S., the design life of PVC is approximately 10-15 years.

Technically, PVC is a molecule comprised of carbon, hydrogen and chlorine. The combination of these elements results in a single-ply membrane that is simple to manufacture. During fabrication, remnants can be recycled and melted down to be reproduced, resulting in less waste.

Because PVC is a thermoplastic, this membrane can be softened into a semi-solid state and infused with UV light inhibitors and anti-soiling fungicides. During installation, multiple sheets of the fabric can be overlapped and fused together in a process known as weldable seam technology. Once cooled at room temperature, these sheets form one continuous membrane.
