Hi guys, i have seen a composite roofing product around which is colorbond foam and another sheet of colorbond...i think.
Anyone used this product at all? How do you fasten the sheets? The product i saw on TV looks about 150mm thick. So i was wondering about the achoring of the sheets. Who supplies it etc...
Would that be the same at they make site huts and industrial fridges from? I haven't seen it used as roofing but I guess that isn't a bad idea. I imagine it would be fixed in place with longer roofing screws.
I think I know what you're talking about - Thermaspan. It's basically Colorbond/Zincalume on top, a flat, white metal panel on the bottom and foam in the middle, which acts as insulation.

We're waiting for ours at the moment. Approximately 25m² is costing us $2,345 including flashing etc, so it's not cheap, but I think it's definitely worth it. It's self spanning as well.
Hope this is what you were after!
Cheers,

Yep it's pricey but it's strong and there are savings to be had with construction time and material savings......my brother in law has used it in the past in houses he has designed and built on the North Coast of NSW.

We used the stuff many years ago to cover a 4 x 4 m deck. It was about 100mm tick and spanned the whole 4m without support.
Although expensive, you save on labour and materials for the supporting structure that would normally be required.
Plus you have the added benefit that it is insulated - the deck we had it on was in Qld and faced west, yet it was very comfortable under there, even in the middle of summer.
Ive seen what you describe in a commercial situation used as a roof covering at BRL Hardy's wines where they build a huge air-conditioned wharehouse. It was in massive panels lifted into place by crane.
The most recent case was on some TV show where they are building an eco-friendly village and it is used again as a curved roof covering but is incredibly expensive.
