 Re: Fires now up to temp but not sure if enough insulation
Wayne,
Personally, over the blanket I'd go for three inches on the sides and five inches at the apex. That way, you would have no heat bleed at all. Remember the FBF axiom, "You can never have too much insulation." I'm satisfied when the exterior of the dome is cool to the touch when the hearth floor is at 900 F. Now's your chance; I'd say do it.
Jim
