roughly.   some of the materials toward the bottom of the page are a tad better than 1/2 hot face.   
but approximately that is true and that is a good reason to look for something better....

Colyn,
 
It seems that the firewall blanket has to serve two purposes, one to keep the fire from penetrating the firewall, and two to keep the heat from softening the firewall.  If I read the chart correctly, you would start softening the firewall at about 500F in the engine compartment, since the 3M material cuts the temp in about half.

Here's a document of the sort I was hoping to find for the intumescent paint.
It shows hot face vs. cold face temperature.
Based on the original, it seems to me that is the worry.   e.g. the firewall gets soft somewhere above 250.
