Thanks for all the responses. Much appreciated. I'll up the thickness to
18mm as recommended.
I don't want to use contiboard as I need a specific depth to make custom fit
shelves in a utility room. There's a boxed in downpipe at one end and want
the shelves to be exactly same front/back depth. Also I want to sand, prime
and paint them with the same emulsion as the wall to blend in.
