Cellulose Insulation For A PC Oven

[pcbeachrat]

Looking to get into PowderCoating soon,as I already have A sandblasting set up and alot of my customers ask me about powder coating all the time. I am A retired Paint Contractor with 37 years experience, but have never touched A PC gun in my life.After extensive research, and many trips here to Caswells, I have decided to now build An oven to powder coat from. I have alot of unopened cellulose insulation laying around and was wondering if this would be sufficient to insulate a PC oven with, providing it is packed in tight and 4 inches thick.Supposedly it has A higher flame retardent rate of common unfaced fiberglass insulation and I feel it will hold 400 degrees quite effeciently, but My main concern is..will the constant usage of 400 degree temperatures make this cellulose, "settle" or break down or anything of the sort?I have many more questions coming soon, but I will try not to flood you all with multiple questions concerning this build..Please let me know your thoughts on using cellulose Insulation on a PC oven..Thanks..

I don't recall anyone ever attempting to use this in an oven.

Doesn't all insulation rely on air pockets to aid insulating properties, so I would be concerned about packing it in tightly. I guess I also would be concerned about settling and the possibility of small loose fibers making their way into the oven.

Unless cost is the overriding concern, I wouldn't use the loose insulation.

If that's all I had, I'd consider using it.

To avoid settling, think about using chicken wire, just like steel mesh in a concrete floor. The wire would hold the fibers in place and keep the material on the top from weighing down on the material below.

Just a thought,, your results may vary.
