About UPVC By many standards UPVC is a new building material, first used broadly during and after World War II to meet many of the critical infrastructure and safety needs of that time, it blends attributes of traditional materials with advanced performance characteristics of today’s and tomorrow’s building products. Durable, environmentally sustainable, versatile and low maintenance requirements are just a few of the properties that have propelled the growing use of UPVC in the built environment and made it one of the most important materials used in the building industry progressively over the last 60 years. Advantages of UPVC: Great insulator Low maintenance Energy efficient Recyclable Not corroded by salt air Does not warp or discolour Will not rust UV protected Cost effective and extremely affordable Low impact on the environment
