Contact Ullman Scicily and check with Pablo. Like I said, I suspect that the 'invisible chute' is made of window material, but who knows. Surely not a woven cloth, but some kind of laminate. I dont know more about that spi. I guess there is a reason Pablo dont have more information about it on his webpage.
