Banding as fire clip?

broadgage: 
 

Yes in my view provided that the fixings holding the banding to the structure are reasonably fire resistant.

Screws into masonry or substantial timber should be OK provided that fibre wall-plugs are used and not plastic.

Fibre wall plugs used to be supplied by the makers of night storage heaters for fixing the heater wall brackets to the wall. I have used plastic plugs on occasions and long screws, with no problems found. I suppose that most of the heater weight is downwards onto the heater's feet. But the plastic plugs may become soft if they get too hot. Still, the wall bricks will probably conduct heat away from the plastic plugs.
