I'm about to start rebuilding my 21ft Olympic and I'd like to replace the floor with a composite floor - I believe it will be stronger, lighter and less likely to rot. I was reading about them today on the forum and you know I can't find the topics tonight.
I've read there are different types; polycore, honeycomb, balsa, but I did read somewhere in this forum you could by a sheet for around $100. I did get a quote today from ATL Composites; they quoted my $424 ex GST per 2400x1200 sheet - seems a bit excessive.
Can anyone provide advise in this area or better still direct me to a supplier that has a good product at a reasonble price.
I'm looking at it more from the weight side of things. At less than 1/2 the weight, I believe the weight can be reduced by 80-100kg on my 21 footer.
I have to look at the whole picture. I'll be fitting a bigger fridge, aiconditioner, bigger water tanks, toilet/shower etc - it all adds up. The lighter I can keep it, the easier it will be to tow and less fuel.
I tend to agree with you Greg in the weight department, and 2up you also have a valid point in that plys are much better these days especially marine grade but it is a concern of mine that you only need the moisture to get in in one point and you could be back at square one before you know it, my initial thoughts if using ply was to coat it all over in glass before glassing it to the body of the van.
If you get an email telling you that you can catch Swine Flu from tins of ham then delete it, it's Spam.
Hi oztrade, I've been lead to believe modern external ply uses the same glue as marine ply but a lot cheaper and you can get it with one good ,sanded surface or two sanded surfaces. We went down this road on our rebuild youtu.be/pklpXjGjem4 and the weight came in at 1630kg with no water tanks, air con or shower. The ply floor gave a solid base to screw the cabinets onto as nothing was attached to the outside walls
