TPO

WHAT IS IT?

The TPO membrane is a single-ply roof membrane constructed from high quality thermoplastic polyolefin. The standard color for this membrane is white; however, it is available as a special order in other colors depending on the manufacturer.

WHY USE TPO MEMBRANES?

TPO offers the “best of both worlds” combining the proven flexibility and weather resistance of rubber and the performance of hot-air welded thermoplastic seams. TPO seam strengths are reportedly 3 to 4 times those of EPDM’s adhesive and tape seams. TPO is highly resistant to tears, impacts, punctures, and ponding water. TPO is a lightweight single-ply membrane which is ideal for retrofit systems without adding excessive weight to the roof deck.

FEATURES & BENEFITS

  • Long-term weathering, UV resistance & heat-aging properties
  • Resistance to harsh chemicals, industrial pollutants, abrasions, & punctures
  • High breaking & tearing strength
  • Resistance to ponding water

WARRANTIES

Most manufacturers warrant their TPO products when used in either a re-cover or new installation application for 10 or 15 years. Upgraded No Dollar Limit Manufacturer Labor and Material Warranties are also available. A standard NDL Warranty term is 15 years ;however, 20 and 30 year terms are available.
