Need thin dense insulation for a couple areas.

[caspian]

I changed my design plan midway through and have caused a small issue. the distance between my dome and the brick wall is only 2 inches on 3 sides of the dome. All the other areas have plenty of vermiculite to insulate.

So I want to protect the 3 sides of brick from losing heat. I'd rather not buy a whole roll of insulation blanket for the small areas I need. My question is, is there a commonly available dense insulation I can put between the wall and dome? I looked at an autoparts store for enging heat insulation (like you have in your car), but they don't carry it. Any other ideas?

Thanks
Chris

I am thinking about something like this:

Amazon.com: Thermo-Tec 14130 24" X 48" One Sided Thermo Guard Flame Retardant: Automotive

Have you considered using CalSil board for those spots? That is a great insulator. One and a half inches of CalSil insulates as well or better than 4-6 inches of vermicrete. You should be able to put some small pieces in there (wear a dust mask when you do it!)

I have some CalSil offcuts I can send you if you think that will work.

Sounds like it will be better than the idea I had.

Thanks for the generous offer. I called around and found a place that sells cutoffs and will be picking up a piece that is 12" x 36" x 1", so i will be able to do a 12" x 12" on each corner. Best part is the price is only $7.50.

Thanks

If its dense it aint an insulator.
Carpet, really?.....

Use ceramic fibre blanket.

Re: Need thin dense insulation for a couple areas.

did you even click on the link, it's more than carpet. it's a moot point. I went with the CalSil board

I am going to use the Thermotec as one layer in the door since i already ordered it.

The door will be thermotec, stainless, 1" of CalSil, and stainless (the CalSil sandwiched in the stainess)
