Howdy hargs - Regret to advise that I know nothing about this product.
However.......I've been considering something (anything) to cope with heat inside the CT on really hot days. I have to say this looks (and reads) as a pretty good option to me.
I notice these guys have it sitting directly on the CT canvas, as do other ideas that I've seen. I wonder if this will result in rubbing of the canvas and is it the most effective way of keeping the heat out. Is that your concern too?
It seems to me that the principle of the Tropical Roof is that lovely air gap to create an air flow and cooling effect. However, clearly this product can be extended over the roof on poles for the fly / tropical roof effect. But I'm as lazy as the next bloke and if I can get away with using less poles and just leave it on, then that's fine by me.
I'm interested in what your thoughts are and what others have to say.
