Amelioration veranda insulation polycarbonate roof

Hi the éconologistes,
I come to you for a question on porches.
Recently acquired a house, the latter to a veranda north, north / north / west exactly.
positive point is that the northern front of the house is protected by the conservatory. The walls of the rooms overlooking the veranda are not cold and it greatly increases the comfort.
negative, the porch is not very hot.
As I dealt with the attic insulation for the rooms: 20cm insulation roll over the rooms. I think it can be quite a bit to improve the thermal insulation of the conservatory, which will be equally beneficial for the home.
Rather than a long explanation, a diagram:
so the veranda is in two parts:
- A game with a corrugated iron roof that dates back high against the wall of the house but has a false ceiling (to 2m20) insulated with glass wool 20cm, that part of it that is ok.
- And a second portion with a polycarbonate ceiling, the big downside of course.
It is the former that made proprios ask polycarbonate last few years (less than 10 years) but they are simple plates 16mm. The plates are placed with aluminum profiles that make thermal bridge which suddenly gives condensation.
The idea would be to improve the insulation of polycarbonate ceiling without losing the contribution of light or heat in the afternoon when it's sunny, the house being slightly oriented towards the west.
I therefore was my idea.
Would it make sense to place a second layer of polycarbonate below the first?
Again a diagram:
No need much explanation here I think, basically the idea is to place the second layer of polycarbonate (blue) as on the drawing.
In your opinion is that it may be beneficial? Or is better to redo everything correctly with larger plates and insulating but more expensive course? What I could not do right away for lack of much diminished budget in part by the chassis, attic insulation, electricity and some other works
