Birrddog:
Do you have any experience with those whole house fire blankets?
I have not seen the blanket system you mentioned. I have used standard "wrap" to protect buildings. Basically, given enough time, we go in and wrap buildings with a protective cover...we will also set up a sprinkler system using "pumpkins", (portable pools), and suction pumps from streams. Here are some pics from a wrap we did in the wilderness in Northern Idaho back in 07 at the Monument Ranch. We had to fly in EVERYTHING---this was a three day operation:
The best way to protect your home is by utilizing "Defensible Space"---this is a home in the middle of the San Diego fires a few years back.
I did hear of a system being developed after the San Diego fires where a sprinkler system is built into, and onto the home utilizing the water from your swimming pool. It would be hooked up to a retardant chemical reservoir and right as you walk out the door to evacuate, you would hit the switch. Your house would be covered in retardant.....nasty to clean up, but better than the alternative.
