I have taken a DN1 frame and put polystyrene sheet inside it. A quick spray of adhesive on the faces and a sheet of baking foil as a reflector makes a good insulated dummy boardI've put polystyrene sheet between the correx filling the empty frame and used them on either side of the box overwinter. Think they give more insulation than a part-drawn or empty brood frame. ?
