I'm not sure of that stuff allowing more light...
I'm familiar with that stuff. Sharp edges, saggy and ugly, but then again. So am I, I suppose.
I havent ever worked with it, but if it is for a green house roof I would hope it does not sag. It comes in "clear" so fingers crossed that equates to allowing more/plenty of light. I wonder if it has sharp edges and such, if that could be softened with something. I haven't looked up the DIY on it as of yet. I was hoping it faired better than all I have looked up on acrylic since acrylic warps. I suppose final option would be to make my own glass top...
