Section rack - polystyrene?

[Jimmy]

I've been reading up about producing round sections/cut comb and a few writers mention problems getting the foundation on the edges to be drawn out.
They either recommend swapping frames from the outside to the middle as the middle frames near completion or having extra insulation for the two outside frames.
Does anyone make a national size section rack from polystyrene? Would this get round the lack of warmth problem?

TIA.

Round sections are the answer really though I found when doing "round sections" that a poly super was more of an answer.
