Rear Firewall

Orange,
as far as I know the sailpanel area is not even addressed by most people or sanctioning bodies. I could be very wrong however. I have never seen fire caulking mentioned in any technical rules.

The sheet metal I used is 24ga and the 'intumescent' fire caulking is something Im doing for a complete system. I build commercial buildings and it is used at all firewall junctures.

Intumescent caulking is not only fire proof but it expands to fill any gaps in the wall or break and keep the fire contained. You can buy it at Home Depot. There are two types of fire caulking a 'Static' version & an 'intumescent' version, read the labels carefully. Use the appropiate type for your application.

I still have to put some sheetmetal patches over the openings for the third stop light and the two openings for the flashing 'cop' lights. where the package tray goes. Then build sheetmetal cans for the speakers to close up those openings.

I will say that I do shurely miss the flow through ventilation before all of this was closed up, its getting hot in Texas.

Then after I figuure out how high the driveshaft tunnel will go I can set up the main firewall with the 'firesafe' insulation and caulk that whole thing in. I will continue to post pics.
Hope this helps
Andrew
