Aluminium is probably a good choice, as it is easily available, good to work with if you have basic tools, and light weight, but you may have problems sealing different sections together, and is probably not that practical to seal on a small scale.

On a small scale/non-functional prototype, fibreglass could be used, but would not work on a full sized version, or with significant pressures.

Many widely available materials will fit the airtight specification, but are not practical to use.

Things to avoid would be foams, and materials with bubbles of gas/liquid (including wood).

If you want to use the same material on the prototype and the real thing, you need to consider the effects of extremes of temperature, various types of radiation, and pressure.
