PVC insulation supplies, like PVC fittings & jacketing are manufactured from polyvinyl chloride, an impact resistant and durable material. PVC fittings & jacketing are designed to fit over insulated pipe fittings, providing protection to the underlying structures. PVC insulation supplies provide vapor retardant protection to insulated pipes and come in a number of different options such as couplings, cut and roll, elbows, end caps, fittings, and more. PVC offers a lower overall cost, durable and long-lasting protection, as well as an aesthetically-pleasing finish.
