Although corrugated iron is not easy to find, or rather, it has to be specially ordered not bought "off the shelf", we do have one corrugated material that is readily available. That is a mix of inert fillers bound by some tar-based mix. Following this topic, I called a pal who is planning to replace his garage roof, and who, when last I spoke to him, was debating the merits of various coverings. He eventually settled between two choices, this corrugated, what-ever-it-is, and felt. The cost of 3/4" board, covered with two layers of felt, the top one with a sanded surface, and all properly bonded, was about 15% less than the corrugated stuff, and that would only have been the single thickness of the actual material, ad this less heat insulation. Not hard to see why he settled on felt.

I think I've hit on the reason why wriggly tin doesn't rust in the antipodes...it's cos, being UNDERNEATH the earth, the rain drips away from the ridges into space. :o)) Len Smith MODEL ENGINEERING DISCUSSION LIST.
