Generator Compartment Insulation - [email protected] - 03-06-2021

1986 40' Classic #121 with a Perkins Diesel Generator. I need to replace the sound deadening insulation in my generator compartment as it is crumbling and falling off. Anyone have any experience with this project? What material did you use? I will likely pull the whole generator and engine out to get good access.

Not from personal experience, but from a Prevost group, here's what was recommended there as the go to material.

I have several 4’ x 5’ sheets of 1-1/2” foil faced with a dampening barrier.   I can send you a picture if you pm me.   It is left over from my manufacturing processes.  You will need a good adhesive and it is recommended to use retaining pins to back up the adhesive and keep it off of hot exhaust.

I went with Thermo-Guard FR 48" X 72" two-sided part #14125 available from Amazon prime $63.08.

"Thermo Guard FR offers the best in heat and sound insulation.  This lightweight, durable shield does everything: reduces sound, absorbs vibration, protects from radiant heat up to 1500 degrees and provides an extra layer of insulating padding.  This product features 100% synthetic fiber felt that provides sound and comfort control and a high-tech foil heat barrier that blocks more than 90% of radiant heat. Being only 1/4" thick, Thermo Guard FR provides a very high level of performance with minimal thickness. Thermo Guard FR is very easy to apply - it can be trimmed to fit anywhere. Great for use in trucks, RVs, buses, cars, aircraft and homes."
