If it's a portable grill, why don't you just pull it out some when you use it?
If not, you can do many things to make a heat deflector. Sheet steel or aluminum, ply-wood with a foil facing, solid insulation with foil, a water heater blanket (not w/ the cheap plastic facing), and the aluminized fiberglass material used to insulate race cars (you can buy it in rolls).
