Creating a void between the old ceiling and new is better but ideally you need to eventually consider insulating the top of the concrete roof with solid insulation and a better. This method eliminates the need for ventilation and the risk of condensation whilst providing superior thermal performance to cold deck.

Insulating concrete is made with special lightweight aggregates meeting astm specifications c332 or made by using preformed or formed in place foam with cement cement sand mortar and also with lightweight aggregates. The supports will rot if they are made of wood or rust if they are of reinforced concrete. Can you give me some information on insulating concrete for roof decks.
