We have discussed Sundeala at lenght on the forum, but I can't find it as a stand-alone item in the index, so it must have been when talking about baseboards in another thread.
Can anybody help by saying where :?: Was it on a layout thread :?:

There are comments about it all over the place Jeff, including yours and Petermac's own and others on the first page of this topic. Would be good to have a post on Sundeala by someone who has experience of it, good and bad points. One for the Index then.

fine, not loft board that is to dense, plus standard board is cheaper.

Interesting Owen - I didn't know there were 2 types of board (although I do know you can get "ordinary" and water resistant).  I agree - usde the cheaper one - it's absolutely fine other than as stated earlier.  Here in my part of France - chipboard is chipboard (or maybe that should be "frites"board         )

Many thanks every one, I can get chipboard at a knock down price, so many thanks.

I could not find any reference to Sundeala on this forum but there are lots on RMweb.
use google & type in
"sundeala" site:rmweb.co.uk

We have something similar down under called Canite & that needs lotsa support. One of my first "serious"  layouts used this onto top of 12mm chipboard & I used it so I could cut grooves easy for wire in the tube point rodding & to accept track pins for spiking of rail since I hand laid all track back then in the dim past.
