Hi, I have read through many Q&A;but still am unsure what to do. We want to put in a fire place with an insert. I see that standard prefabs fireboxes from the normal building supply company dont meet the requirments to have an insert in them. What style of firebox can be purchased that would accept the insert? What do you look for? I can build the structure to fit anyway needed. Do you have to buy a firebox and then an insert or is there a built in available? Are "built ins" inserts that were designed to go into new construction to begin with. Is it easier to just go with a stove? What is the difference between insulated and non insulated fireboxes. I am very needy and confused. I am married, so I can take abuse, so go ahead and provide "guidance". Any links, products etc. are appreciated. Thanks very much.
