Thanks Phil. Do you recommend any brand?

Not really - they all meet stringent fire regulations, just get a cheap one
if you can find one, and fire rated foam is pink, not yellow.
It's highly unlikely there's going to be much heat up there, but better to
be safe than sorry.
You'll still need to point over with sand and cement after the foam's set
BTW.
