Plastic tiles for roofing?

[emosbur]

Sorry to ask this, as I am sure it has been answered before. I am lookink for platic sheets for tiles, stone walls and the like. Time ago I saw a post witj links to several manufacturers, one was a cheap one. But I only find Wills in my search, and if I search for "tiles" I get a lot of messages (may be that the problem is that I am using the wrong words to search).
May you point me to sources for this material?

Many thanks.

Emilio.

Do a search of the forum there was a discussion a few weeks ago on this very topic. Wills/Peco are another option but your best sources are model railway shops, I have various makes of pan tiles in plastic.
