Cardboard is an insulator in dry state.But when it is wet it can conduct electricity
Yes
The problem with using cardboard as an insulator is that it is too easily damaged in a variety of ways. It tears easily, it can be set on fire relatively easily, it absorbs water very easily and it will disintegrate or become moldy, if it does get wet. So although cardboard is an insulator, it is not durable enough for most purposes that require an insulator.

No.
Yes
Wood is an insulator.
Wood is a better thermal insulator than glass, which is easily cooled.
You should use something with a low density like foam...

yes
Dry wood is an insulator
wood cannot cnducts electriccity hence it is a insulator
wood is an insulator because charges stay on the point of contact.
