I am building a new family room addition with a direct vent fireplace (Heat&Glo 6000). The building inspector noticed the fireplace. I mentioned I was having it installed and I wanted to insulate the wall cavity behind the fireplace. He said to remove the kraft backing and to install a fire shield/stop such as thermaply or thermapan (sp?) 1/8 inch thick. I guess this would be in place a drywall. Does anyone know what he is referring to because I cannot find anything worthwhile using Google searches.

Here is a link for Thermo Ply:

We use the HNG 6000 quite a bit. We always install after insulation. We have the insulation contractor fill the roof and stud cavities full of foam and leave a very generous airspace.

What is special about the thermo-ply? Will it provide some sort of heat/fire shield? Or does it just keep the insulation tucked in?
What do you use between the insulation and the fireplace?
Honestly, I'm not familiar with thermoply. I just found the link since you were inquiring. It is just a thermal barrier, I believe I read that it will give you a 1 hour rating.
Between the insulation and the fireplace we just use a generous air gap. If you build the box too tight, then you need a barrier such as thermoply.John

I'm not sure about your instilation but we have the chase DW'ed or sheathed to insure the insulation will never fall onto the heater or imto the airspace.Garett
We do not need to install drywall just make sure air space is good as required.
I have done several vermont castings fireplaces.
