High Seam Strength comes from the melt window of the membrane. A wider temperature range assures a solid weld with the greater flexibility in varying field conditions. A high seam strength means less number of cold welds and increase productivity. Even after the roof ages it also ensures that it can be serviced just as a new one would.

The brittleness point is a measurement to determine the flexibility and is an indicator of the polymer deterioration in the membrane. The ultimate test of TPO flexibility is achieved at extremely cold temperatures. Passing the test means that the roof is aging appropriately within the life span and still meeting the initial requirements of a new membrane.

The thickness of a sheet directly affects its ability to withstand long-term weathering, abrasion, UV exposure and weldability. Over time the consistent thickness measurement means a sheet is standing up to weather and staying water tight. Losing a mil or two doesn’t seem like much until you add them up. Are you still being covered by 60 mills 7 years later?

With over 10 years in the TPO space, JM has observed how the industry standard requirements continue to evolve as the competitive landscape intensifies. But TPO roof performance and customer expectations have not changed. The roof needs to perform and withstand real-life conditions, harsh weather and REAL life temperatures.
