    Hi all, I'm insulating the pitch of the roof and I have a tricky bit around the chimney where there are noggins in the way of the normal airflow path


    What would be the best way to deal with this?

    I've considered filling the bit between the chimney and the joists with expanding foam (as I think that this doesn't then need an airgap above). Would this be ok for these small gaps here?

    And/or building over the obstacles as shown in the diagram below.


    Note that the noggins are actually twisted and parallel with the chimney wall so the wedges would need to be a little different. Not sure what to make the wedges out of.. wood might be unnecessarily heavy..

    I also considered drilling holes through the top of these noggins, but these are load bearing so probably not a good idea without some kind of reinforcement which would be tricky as they are twisted noggins.

    I'd be grateful for any advice as a bit out of my depth
