insulating arch

[sweetwater sugar shack]

What is better to use archboard or ceramic blanket on oil tank arch it is bricked I know I will have to remove brick glad it is not cemented in

The blanket might be an easier route since your oil tank most likely has a funky shape to it.

I used blanket in my oil tank arch. Was easy to work with.
