Stove Insulation

Question

Last year mice got into our TT stove and used the stove insulation to build a nest in the oven. We cleaned out the oven and continued to use it.

Today I decided to take the stove out and dismantle it in my shop. the mice took away most of the insulation from the rear of the stove that was between the outer sheet metal and the rear of the oven. I am cleaning the area out and spraying it with Lysol. However, I need to replace the missing insulation. It's approximately 1 inch thick and about 2x2 feet square. Is this just fiberglass insulation or is it a special high-temperature insulation? It looks and feels like fiberglass. I have rolls of fiberglass insulation for the house and would use that (minus the paper of course) if it works. I don't want to buy "special" stove insulation for $$ if it's just regular fiberglass insulation.

Anyone know what that insulation is?

Thanks
Steve

I would think it is the same stuff. You can test the house stuff, apply some heat to it, and see what happens. Use a BBQ lighter, and if it burns stay away from using it, however if it will not melt in about 5 seconds exposure to the small flame, and if there is no flame spread, it should be stable enough to use on the back of the oven.

You only need it about 1" thick. Insulation is not effective anymore if you installed it without it being fluffy, and full of air pockets. So don't try putting in 3.5" of insulation that will become compressed to 1" once the range is in place, it will not work nearly as well as 1" to 1.5" of insulation that is still fluffy.

I had that happen several years ago at my cabin. The appliance guy told me to use regular fiberglass insulation (with no backing) I did and it worked fine for years.

I've done this task. Make sure you pull ALL the insulation out, not just the stuff in the back. I ended up pressure washing the cavities around the oven for quite a bit to remove the smell from the infestation. Regular batt fiberglass insulation was used to replace the original.

The same thing happened to me last year. I found this link that says fiberglass insulation is good for 1000 deg F. So, that is what I used.

Thanks for the replies, everyone.Good idea on pressure washing the cavities to remove the smell.I'll clean up some more and replace all the insulation with new fiberglass home insulation that I will pull apart to get the right thickness (about 1").Those mice sure make a mess.  Apparently the fiberglass doesn't bother them and they see it as a convenient building material for nests.Steve
