Why consider TPO / FPO?

  • Hot-air-welded membrane seams
  • Mechanically fixed or adhered options, where specified
  • Compatible build-ups for different structural decks
  • Details coordinated around plant, outlets and rooflights
  • Product-specific selection for exposure and roof use

TPO and FPO terminology varies by manufacturer. Specify the actual product, attachment method, compatible insulation and full roof build-up.
