Hi Jay-

Up over here, on the northwest side of the planet ;-), these products can
be had at many hardware outlets aside from home depot.  They are
intumescent caulks, and come in a cartridge suitable for use in a standard
home use caulking gun.  They are typically displayed in the same area as
all the other window and siding caulks, being marketed as 'fire block',
'fire stop', or some such.  When packaged as home repair materials they are
a fraction of the cost of when the same material is packaged for aviation
use.

FWIW-

I'd caution that most fire rated caulks from the hardware store are 
essentially just silicone that have a fire rating to satisfy a 
particular building code. The one I tested was no better than red rtv 
gasket compound. While either will satisfy our local inspectors, the 
silicone products are not near as good as the itumescent 3M product. 
Less than 600*F vs. 2000*F. Aluminum melts around 1100*F as I recall.

Occasionally you do get what you pay for.

Check local electrical supply houses for the 3M Fire Barrier.  It's used in
industrial applications for (guess what) fire barriers.
