Bryan Posted October 23, 2009 Report Share Posted October 23, 2009 I have looked through all of my code books and can't seem to find a reference that addresses chimney chases. Can anyone point me to a code reference to whether fire blocking is required for the chimney Chase above the roof plane? Bryan Quote Link to comment Share on other sites More sharing options...
Brandon Whitmore Posted October 23, 2009 Report Share Posted October 23, 2009 I am not aware of any requirement to install fireblocking above a roof line. Isn't the intent of the code to prevent fire from spreading between floors, and into the attic? I see a lot of chimney chases, and can't recall seeing fire blocking above the roof plane.

Bryan Posted October 23, 2009 Author Report Share Posted October 23, 2009 May be above the roof plane was the wrong choice for the description. What about at the roof plane/sheathing line. Bryan Quote Link to comment Share on other sites More sharing options...
Jim Katen Posted October 23, 2009 Report Share Posted October 23, 2009 May be above the roof plane was the wrong choice for the description. What about at the roof plane/sheathing line. Bryan No. There should be fireblocking at the plane between stories and at the ceiling line of the top story. No need for it at the roof plane. - Jim in Oregon Quote Link to comment Share on other sites More sharing options...
