TPO Basics and Benefits
We discussed TPO membranes in a previous post; also known as thermoplastic polyolefin, TPO membranes are highly reflective and feature heat-welded seams for extra strength. Add energy-efficiency and weathering package options to the list of features that make TPO an attractive choice for many commercial roofing projects. Professional Roofing magazine reports “One factor driving the growth of TPO and PVC membranes is the ‘green’ building movement. Global warming has become a focal point for many property owners, specifiers and government agencies.” Additionally, the use of larger TPO sheets may reduce the labor costs of installation. cites “cost considerations, ease of fabrication, and potential for improved performance” among the reasons to choose this roofing material. The Johns Manville website states their “best-in-class TPO formulation has remained unchanged since launch and has proven to be durable under real-world conditions of heat and ultra-violet (UV) exposure.”

Benefits of TPO membranes listed on the Johns Manville website include:

  • Cost-effectiveness without compromising reliability
  • Membranes reinforced with a polyester fabric and manufactured with an ultraviolet-resistant thermoplastic polyolefin formulation
  • The Johns Manville formulation makes for installation with more pliability, flexibility and weldability
