Just had a customer in Tiny who had asked a woodstove installer from Midland how to install a heat shield. This individual apparently sells wood stoves! Does he know the code and rules? I would say yes. But he does not clearly know material names.
He told the individual to use resilient channel, which he did. But resilient channel is only 1/2″ of clearance.
Code states 7/8″ is required!! Oops..
What you need is called Furring Channel which does provide the 7/8″ clearances. So if in question get furring channel.. and measure it to ensure it is 7/8″ and you won’t have to do it over.
There were some other problems with dimensions of heat shield as well, which he had to make wider; if you don’t know the rules please save yourself time and simply ask.
