Insulating Conservatory Roof with extra Polycarb views pls

[Invicta]

I've read a number of posts relating to insulating a conservatory roof but haven't seen any that mention an idea I have.

First off I have to say that I appreciate the best way to insulate the roof would be to get it tiled/roofed properly but I don't have the money for that.

I have been thinking about adding a second layer of twin wall polycarbonate sheet (inside) below the original one. Attaching the sheets to the exposed horizontal surface of the joists with twist lock "buttons" so I can take the sheets off to clean them when required.

I wondered what other people think about this please?

Thanks for looking,
Bern

I doubt it will do much to be honest, plus it will look a bit naff.

Mw,

Thanks for the reply
It did occur to me that if this was such a good idea lots of people would of done it.
