Philofficer Posted January 6 Report Posted January 6 We are in the process of stripping out the interior of our 1964 M20E. Behind the rudder pedals is a fabric blanket, presumably to insulate the cabin. It doesn’t look original although it is mounted behind the equipment behind the avionics and would be impossible to completely remove. It’s falling apart and has to go. Does this piece exist in other Mooney’s? (See attached pictures - the red is over spray from some poorly done interior painting). At this point I am going to cut it out and replace it with dense insulation. Quote
TaildraggerPilot Posted January 6 Report Posted January 6 That looks to be the original fabric firewall “insulator” material. My footwells have some newer, lofty off-white fibrous-type insulation laid in front of the tired original fabric. You may want to go ahead and replace all the heat/vent scat under there while you have the access. They don’t look to good. Quote
Philofficer Posted January 6 Author Report Posted January 6 Thanks for the reply. Yup, that’s the plan. Quote
DCarlton Posted January 6 Report Posted January 6 On my F, I’ve always wondered how that would ever be replaced. It seems wedged between the steel frame and firewall. Quote
N201MKTurbo Posted January 6 Report Posted January 6 I think you would need to remove the engine, everything connected to the firewall and then drill out all the rivets holding the firewall on. Sounds like 80 hours of labor to me. Quote
Gee Bee Aeroproducts Posted January 6 Report Posted January 6 Use Ensolite foam , I can do your ducts in black sceet if you want finish ends with lined clamps Quote

It doesn't have very high temperature performance. It is only rated for 120C. The original material seems to be fiberglass wrapped in aramid cloth. Which would withstand a much higher temperature. I believe it is there as a heat barrier in case of an engine fire. 1 Quote
GeeBee Posted January 6 Report Posted January 6 120C is 248F. If you got 248F on the firewall, you got bigger problems. Quote
