I'm looking to add insulation to the cavity in a conservatory wall during
building but I'm not clear what thickness of material to use. I had
assumed that it would be necessary/best to fill the cavity but
investigations suggest that less than 1/3 this thickness seems to be
generally used. Is one option a false economy or the other a waste of
money?

NB We are intending to use the room in all seasons.



Yes it does make sense to fill it. Insulating foam or insulating glass
fibre or Rockwool batts are typical.

Thanks.
It made sense to me but every (commercially built) one that I checked seemed
to have used something like 1-2cm thick foam. Cheap?
