TPOs in Europe
I read the article "TPOscommodity or specialty?" June issue, page 38, with much interest. Overall, I think the author, Stephen A. Sharp, owner of Sharp Roofing Associates Inc., Ironia, N.J., does a nice job explaining the TPO situation in the United States.
I think your readers would be interested to know that in Europe, where flexible polyolefin (TPO in the United States) first was used as roof and waterproofing membranes, the situation is quite different.
