Thickness of Insulation for Firebox

Post by Newsmoke » June 22nd, 2018, 5:08 am

Dear All,

Can you please tell me the rule of thumb for the thickness of insulation (rockwoll) around the firebox? I decided to go with a square fb.
I was thinking of putting a 2 inch insulation on 2 sides and on on the top.

Thanks for your answers!

I think that's fairly standard.

Many use 2 inch...I use daily a 1 inch ceramic insulation that had a real similar r-value to the 2 inch Rockwoll. Chose it mainly on availability but it works great.
