If you mean the twin-wall polycarbonate sheets that are used for conservatory roofs, then they would provide excellent insulation? But they would restrict the light somewhat.
As you said, you could use silicone to fix them, as polycarbonate is a relatively light material. You could use a clear one for outdoor use. You might also consider using a waterproof double sided tape for ease of removal of the panels.

If you don,t use the panels for your greenhouse, I,ll always buy them from you as I might be getting a grow house for Christmas this goes for anybody on this site as I am after a greenhouse as well.

I would think they still need to be removable because of the condensation/dirt that will get between them?
