A building's roofing material provides shelter from the natural elements. The outer layer of a roof shows great variation dependent upon availability of material, and the nature of the supporting ...
Membrane roofing is a type of roofing system for buildings, RVs, ponds, and, in some cases, tanks. It is used to create a watertight covering to protect the interior of a building. Membrane roofs are most commonly made from synthetic rubber, thermoplastic (PVC or similar material), or modified bitumen. Membrane roofs are most commonly used in ...
PVC decking is composed entirely of polyvinyl chloride (PVC) and contains no wood. [1] PVC decking is a more expensive option in the alternative decking industry, but it provides significant fade and stain resistance and lower maintenance requirements compared to other products, including real teak wood.
A vinyl roof membrane is a polyvinyl chloride (PVC) roofing membrane used in commercial construction. Vinyl roofing membranes have been around for over 40 years in the U.S. and longer in Europe [citation needed]. The British Board of Agrément states that certain vinyl roof membranes "should have a life in excess of 40 years."

A TPO roof membrane consists of three layers: a TPO polymer base, a polyester reinforcement scrim middle layer, and a TPO polymer top ply, which are heat-fused at the factory. TPO roof membranes typically come in three standard thicknesses: 45-mil, 60-mil, and 80-mil. Standard TPO membrane colors are white, grey, and tan, with custom colors ...
A more recent design is the installation of a roof deck with foil-backed foam along with a second deck that is air-gapped away from the foil-backed foam to allow air to flow vertically to a ventilation outlet at the peak of the roof—it is a double-deck design with an air gap. This design improves efficiency. [13]
