In another thread, both Grumpy and I commented on how some things were being ommitted from material specs.
For instance, at a TPO class I took, I 'learned' how to take a single piece of TPO and go around a 'box' penetration. Weld it etc, then put on seperate corner pieces.
I asked " Why not put a term piece on front, then the sides, then the back pan." We don't teach that anymore because nobody will take the time to do that. I asked if it was acceptable. Answer "Yes! It's the better way and fully acceptable and covered by our warranty."
Just one of many mysteries. Any others? I won't go into the fallacy of relying soley on I&W on lo-slopes yet. :laughing:
(But, next time you get a chance, look closely, from the gable end, at the mild hump created with 3-tabs at the headlap.)
