Seeking Construction Materials

[Jinto]

I am looking for thicker foil than the one you use on food to make corrugated iron for a diorama.
Everyone says like the foil on top of yoghurt but I need it in silver and sheets.

Thanks in advance.

Maybe corrugated lasagna sheets? They might be a bit brittle but as long as you don't get them wet you should be ok. Perhaps lacquer them with nail polish before painting, to waterproof them?

Hobbyco and Riot Arts and Crafts should have corrugated plastic or metal sheets for building model railroad buildings.

If you gently score one side of sheet styrene and fold it you could make your own corrugated plastic.

I have also heard that:

old plastic gift cards are good custom fodder

Copy paper drenched in superglue is an alternative to styrene (although you may need to glue 2 sheets together for ideal thickness.)

Just spitballing, but would corrugated cardboard with a flat side peeled off and the corrugations painted silver suit your needs?

That's is what I used to use for wargaming corrugated iron. you can pick what size corrugations you want by using different cardboard.
Also, the corrugations are nice and uniform.
