This course will offer a basic understanding of the benefits of specifying cellular PVC (Poly Vinyl Chloride) railing systems, pergolas and gutters for residential construction projects. Railing systems in residential construction and remodeling have long been considered both decorative and functional however options have been historically limited to architects. Traditional railing materials like natural lumber, vinyl, and composite materials have been the standard choices available for years, but these materials pose several challenges in aesthetics, durability, affordability, and limited design options. Today railing systems can be created using cellular PVC which offers many advantages over traditional railing.
