Foam board on offerat Hobbycraft

[3Valve]

Not sure if this is a nationwide thing but my local Hobbycraft was offering 4 sheets of A1 foam board for £10 today. Well, it would be rude not to.

Gareth, is this foam BOARD, which is the same rigid, hard material throughout, or foam CORE, which is the very lightweight foam sandwiched between two layers of glossy paper?

Was advertised as foam board, but it isn't of solid construction. Definitely some form of sandwich construction going on but the inner core looks to be foam too on these. Confused now.

I think you will find this is a foam-cored BOARD. - As in paper, not plastics...
Mr D will give definitive on this I am sure, but I do not think this will last outside??

It is the paper core stuff. Strip back a corner to check. Bugger.

Andy Rush used to use this sort of stuff outside. We got two different sorts from a guy we knew near March and 1 sort lasts outside well the other does not. Both were a card exterior! What Andy used to do was to PVA the sides and sprinkle Kiln Dried Sand on the surface. This method did not make any difference to the one type of board that delaminated. I have in my Garden the remains of his old Engine Shed that I have converted to a 2 story Factory and it is still going strong some 6-7 years after construction. It is a little Camera shy but does appear in all of these pictures.

Ah, this isn't honeycombed in the middle, it's completely solid, but it still does look like a paper core. At the end of the day I can use it indoors, but I think if I can adequate seal the edges it could be usable outdoors with some sort of outer cladding or render.

It's definitely different to the "proper" solid stuff I've already got in the mancave but all is not lost methinks.

I bought some of this from Hobbycraft. It is a sandwich of foam between card. I'm building a G scale station building from if for my indoor layout (see seperate thread). Its easy to work with but probably unsuitable for use outside without lots of coats to protect it.
