With over 10 years in the TPO space, JM has observed how the industry standard requirements continue to evolve as the competitive landscape intensifies. We performed a series of roof-cuts on jobs installed and evaluated the performance of our TPO overtime in different weather conditions, including relative humidity, UV index, and average ambient temperatures.
The results show that our membrane stands up to various conditions and still meet current ASTM standards verifying that our formulation is proven to last.
