Advantages of TPO

60 Mill TPO Tuttle ISD 

TPO is highly resistant to tears, impacts, and punctures with good flexibility to allow for building movement. TPO's are available in white, light gray, and black with thicknesses of either 45 mils (.045") or 60 mils (.060"). The width of the membrane depends on the manufacturer but they usually come in widths of six to twelve feet and are one-hundred feet in length.

TPO membranes are installed fully-adhered, mechanically-attached or ballasted. Fully-adhered means that the roof is "glued" to the substrate using a special adhesive. 

What actually happens is the glue creates a chemical bond with the membrane.

TPO systems to seal around odd shaped penetrations or a small cluster of Penetrations. The TPO Penetration Pocket fits penetrations up to 3 ½” (90 mm)in diameter

Thermoplastic polyolefin (TPO) single-ply roofing membranes are among the fastest growing commercial roofing products and have gained broad industry acceptance for their many performance and installation advantages.  As demand increases for heat-reflective and energy efficient roofing systems, TPO single-ply roofing membranes continue to provide exceptional resistance to ultraviolet, ozone and chemical exposure.
