I wouldn't use carpet. Too heavy and susceptible to serious moisture
problems if it gets wet, mold, mildew, and ridiculous weight gain. And
it isn't meant to be a fire protection at all.
We are using a closed cell, self adhesive, black foam that meets FAR
burn specs on the cabin side of the firewall. It's not on the web store
yet, but will soon be. We also have a non-fire rated, but otherwise
similar foam on the store right now. Install and seal the edges with
RTV (just in case the adhesive weakens) and you've got a nice tidy
installation.
On the forward side of the firewall we use a ceramic fabric, foil faced,
also self adhesive that looks great and is very user friendly and
inexpensive. It's rated for 1100 deg (foil) but the ceramic will take
much more. Of course, you need to seal down the edges with silicone
RTV, Proseal, foil tape, etc. While no one can claim complete fire
resistance for any material, this stuff will go a LOOOONG way towards
keeping your feet cool under normal ops, and give extra time if you do
have a fire.
Thanks,
