I have to say I was a bit miffed. Its pretty much similar to my design apart from the lumisol, I used polycarbonate but the rest was the same. I actually asked at the beginning as to what they were using so I could source it in my area, I got no reply and so waited to find out what was the miracle substance , even the decking boards were mentioned that I used on mine. I dont know why it was kept such a secret.

But the lumisol is what makes the difference so good on them for sharing this eventually.
