Roofing solutions for TPO membranes

Learn about the advantages of using ENGAGE™ TR POEs in TPO roofing membranes. 

  

Tough, resilient, flexible, and waterproof

ENGAGE™ TR POE brings to low-sloped roofing membranes across the globe. The unique olefin block-copolymer, which is used in the top and bottom layers of roofing membranes to provide exceptional performance, is an essential part of Dow’s diverse portfolio of roofing science innovations. 

Roofing innovations that outperform

Roofing membranes produced with ENGAGE™ TR POE overcome the limitations of conventional polypropylene-based TPO roofing membranes. They’re tougher, more flexible and have superior UV resistance. That means easier installation, increased longevity due to weatherability and excellent hail resistance.
