Upstairs the interior walls are what I call eggboard, Im afraid i dont know the correct name, its two sheets of 1/2" plasterboard with a cardboard honeycomb pattern in between, whilst its great for dropping cables down im not sure it can support anything except picture frames ,Can anyone tell me if it would be possible, using suitable fixings to mount a 42" TV onto. We have got radiators on a couple of the walls but obviousley they have "some" support from the C/H pipes.
