XPS and fire blocking
I am having a disagreement with my city inspector over fire blocking. I am using 2" XPS against the concrete foundation and framing in front of that. All XPS joints tight and taped. The inspector is now saying that since the XPS is flammable, the vertical fire block required per 2003 IRC every ten feet needs to go all the way to the concrete wall. I feel this will compromise the integrity of the XPS system but he is just concerned about meeting the Code. Has anyone run into this before? Any help would be appreciated.
