1 - fiberglass = flammable and needs maintenence
2 - good question and one they will be regretting for a long long time, I guess the eggheads that came up with it have used the method before

don't know
sounds idiotic to epoxy screws in place, I mean moronic

oke:
3 - maybe there was no room above for that, who knows, you'd have to see the drawings and plans.
I thought the epoxied screws were in question Larry. I heard they were too short. Also I can't imagine an epoxy being strong enough to hold up that kind of weight. That whole project is flawed with all the cost cutting shortcuts taken because of the overpriced coruption. Too many problems they just passed over to deal with later, that's not right. Whoever hired incompetent contractors should be held responsible also. There seems to be plenty of blame to go around and now the finger pointing begins.
