I'm helping my dad build a caravan and we don't know what to use for the interior walls. we were looking into getting 3mm ply but unsure what to get from bunnings if anyone had any suggestions or links to some kind of ply/marine ply we could use for the interior panelling would be greatly appreciated.
Welcome to the Bunnings Workshop community @mariacb22. Thank you so much for joining us and sharing your question about what timber to use for the interior walls of your caravan project.
I would love to be doing my own caravan restoration. It's a great project because after you finish it, you can go on adventures with it. There are a few schools of thought about the material used for the interior of a caravan. The most popular of course is using Marine Plywood, then there is just plain plywood followed by specialist products such as AA grade finish Caravan plywood.
Would it be possible for you to post a photo of the caravan both inside and out? This will give our members a better idea of what you're working on. We can then offer you advice and information on materials and methods for your project.
