Hi, I'm new today. Does anyone know what caravan walls are made of. I here polypropylene (plastic?) is light weight, it must have another name and where can I get it or info on it. Thanks Tong

Mine is made of ply wood laminated with fiberglass on the outside and veneer on the inside.

Others are a steel of wood frame with laminate on the inside and aluminum on the outside.

Probably other methods as well.

It wouldn't be polypropylene, it may be foamed polystyrene for the insulation between either timber veneer for the inside and aluminium cladding outside. Or some have fibreglass on the outside and foamed styrene, sandwiched in the middle with ply veneer on the inside. Michael. You can buy the sandwiched sheets complete, just install! Michael

The material you are thinking about is called Monopan. It is a sandwich panel consisting of polypropylene skins and a polypropylene honeycomb core.
It is light and very tough.
It has been used for caravans. Special construction techniques are needed, but they are not a problem to learn or use.
Personally I would not use it for a caravan because it is not as good in insulation as other alternatives. It is also translucent which is a bit interesting.

I would suggest a fibreglass / closed cell polyurethane foam sandwich panel like that made by Vanglas in Yandina, Queensland. This is the material I used to build the camper section of our OKA 10 years ago. Expensive, but stunning stuff.

Have a look at myswag.org as there have been some cracker caravan builds.

When was the last time you had a wheelie bin fail...... there made out of polypropylene and get treated a bit more rougher then most caravans.

Don't do to much studying as it will only confuse you...... and if it wasn't any good nobody would be using it.

Polypropylene and polyethylene are one of the widest used man made materials around and used in a wide range of everyday products.
