I will leave it, I am a believer in "if it ain't broke, don't fix it"

Re: I'm getting closer to my Dome!
New here, and looking for some advice...
I have the ability to obtain 3" thick Foamglass or 2" thick CalSil insulation. The prices are identical. Which would you choose? For the original poster, Has the foamglass held up well?
Thanks in advance.

Re: I'm getting closer to my Dome!
I used both since FoamGlas will not absorb water I put it down on the hearth then CaSi on top. My build is an igloo so water migration was more of an issue than an enclosed WFO. FoamGlas is brittle to work with and you need to take precautions when building the dome but otherwise it has held up just fine. If you are doing an enclosure it is a non issue which one you use.Russell

Re: I'm getting closer to my Dome!
The foamglass has been great. No trouble with the floor where I used it and the walls are still as level as I first laid brick on the foamglass. Of course the real proff would be to tear apart the entire dome and check compression thickness etc. That ain't happening..............Originally posted by JohnR View Post

Re: I'm getting closer to my Dome!
Foamglass it is... Its local and I can get 27 sq. ft. 3" thick for $130.
I'll be looking to sell half... if I don't break too much.
Thanks for the info.Comment

That is a great price and I would use it where ever I could rather than sell it. It is that good!Originally posted by JohnR View Post
One thing I do know, You can not over insulate! Especially if you want to do multiple cooking days off of one firing.
Good Luck

Re: I'm getting closer to my Dome!
A suggestion when you do lay the FoamGlas down, use your leftover mortar from each days work and slather over any exposed FoamGlas ends, which has great thermal properties, but does not handle abrasion well, ie rubbing of your shoes against it during the dome build. The mortar acts as a abrasion resistant coating.Russell

It has been 4 or 5 years since my pven crack appeared! The good news is, it hasn't hurt the oven on bit. The crack is still the same and all is well with the oven to date. The oven is working just like the day it was completed. So anyone with cracks in their ovens, take heart and just enjoy the personality it lends to the oven!
