As building codes and environmental trends continue to evolve, so too does the diversity of roofing material options. These factors, along with others, make construction specifiers’ roofing installation and selection prowess of utmost importance. Among the available choices is thermoplastic polyolefin (TPO).
When properly applied, tests can yield valuable insight into the installed performance of systems, aid investigators in determining the cause of a failure, or help to determine if a product is performing to its intended level.
Siphonic roof drainage differs from conventional gravity drainage in what is called ‘full-bore flow.’ Unlike conventional drainage, a fully engineered siphonic roof drain system prevents air from entering, allowing the pipes to be completely full of water.
