If its purpose is to restrict airflow by convection, metal will do. Copper sheet can easily be soldered to make something that would restrict airflow and s If you want thermal insulation, then PTFE rivited to a metal shield would provide a plastic that will not melt, and the metal would keep it in place, as its hard to form a box out of PTFE. It is not an easy material to glue, but nuts/bolts/rivits will work.
