TPO Love

what brand is that in those pics?>>>

Well, I see some Stevens. Maybe some Genflex and Carlisle. The one that shows the corner of a curb looks more like a PVC, but since there's nothing to give it scale, the actual pattern is a little tough to discern.

The reason these split at the lap is>>>

Only light snow on the hills above Cody. That must mean the picture was taken in July.B)>>>

Mike, the lesson here should be................. I don't type just to entertain myself, trust me when I tell ya something. LOL

PS: We encountered our first failed Carlisle TPO today. I should be able to post the pics tomorrow. Much the same of what>>>

General field condition of the membrane surface. Yes, the little dark tear-drop marks are holes that eaten away. I think they tend to form in the thinnest part of the membrane above the high points in the scrim. "Thickness over scrim" is a number you>>>
