Utility room with plastic roof questions

[ScottishGasMan]

Hey have a new house, got a small utility room with a Twinwall Polycarbonate Sheet roof on it. Now while it lets in tonnes of much needed light, its

Loud as hell in the rain/any bad weather
Cold
Has a huge amount of condensation on it
Loud as hell.

Now my budget for jobs like this is pretty tight at the moment due to me needing to re-plum and re-wire the house.

I had thought, I could get some more sheets of the roofing and fit them to the underside/lowwer portion of the joists which would leave a gap between the current ceiling and a new false one of about 3 or 4 inch, so there would be an air gap to keep a little more heat in, hopefully drown out the sound a bit and means the condensation would at least drip off or run down wall, rather than run down to the ends of the wooden joists and keep rotting them

I suppose I should have asked my question lol, sitting here wandering why I have no replyes


Can any one see a problem with me doing this? And is it likely to have much effect?

Cheers

Adding another layer of roof sheets will obscure more light but will not eradicate condensation, which will inevitably fall onto the rafters as well as the new sheets.

Adding a layer of celotex and robustly sealing all joints will eradicate all condensation whilst also blotting out ALL the light.

It's a trade off.

You need glass but at about £100 per sheet it's a bit pricey.

If it's the crappy 10mm stuff then you could upgrade to the 5 layer 25mm sheets.
