Benefits Of TPO Single – Ply Roof Systems

Thermoplastic Polyolefin Roofing Membranes (TPO)

A typical low-slope roofing system consists of three components: a structural deck, a thermal insulation barrier and a waterproofing membrane, which consists of reinforcing fibers or fabric sandwiched between two sheets of flexible matrix.  The matrix material is either asphalt- or polymer-based.  In “single-ply” membranes, the matrix is made of flexible polymer.  The reinforcement provides dimensional stability for the membrane as well as strength to resist stresses in service.  It is generally made of chopped short glass fiber strands packed in a mat, or continuous polyester fiber arranged in a grid or in a non-woven mat.

Benefits of TPOs
The following benefits and characteristics of TPO are:

  • environmentally friendly and recyclable
  • seams can be heat welded
  • available in many colors
  • resistant to heat and UV degradation
  • resistant to may chemicals
  • good cold-temperature flexibility
  • no external plasticizers added

The result is an ideal commercial roofing system that is reliable and cost effective.  The TPO system is one of the latest single-ply, flat roofing technologies on the market today.  The TPO systems can be installed fully adhered or mechanically fastened.
