brain pick- corrugated glass fibre sheet?

[sandsnakes]

Hi all

I want to put a 'window' in a corrugated sheet steel roof. I recall ages ago seeing opaque glass fibre corrugated sheet being used for this, I think it was glassfibre. Does anybody know who makes it, what its made of, what its called and where to get it?

I am not interested in the clear PVC stuff from B&Q as its not that strong and eventually degrades in sunlight.

You can get clear UV stabilised polycarbonate sheeting too. Mostly used for porchs and conservatories.

cheers,
