I am building a RV-7A. I'm reading that firewall insulation is important for comfort.
All the threads I've been seeing recommend fiberfrax covered by metal foil on the front side of the firewall. I've unfortunately have already mounted the engine and plumbed it up enough that I'm reluctant to disassemble, making it difficult to put insulation on the front side.
I've also read that fiberfrax may not be safe for the interior cockpit environment, and that other sound-insulating materials could ignite and bring a fire into the cockpit.
Has anyone else found satisfactory thermal insulation for the firewall interior? Or if you built to plans and didn't insulate the firewall at all, are you satisfied, or regretful?
