My gable walls bulging a bit, but its within tolerances 'for now' and I'd like to keep it that way. I've been recommended by an SE that I strap my first floor (floor & ceiling) joists at regular centres, and board the loft with ply to prevent my wall bulging any further.
So the first floor (floor) level is fairly self explanatory, take skirting board off, notch out the top of the joists, apply strap across 3 joists and a couple of bricks, job done.
Now the first floor (ceiling) level is a bit more complex.
I can see a few challenges -
1- I have 3x2 Joists, if I boarded this how would I get enough insulation in there if I boarded it? Could I insulate over the boarding? Or can I sister/stack the ceiling joists to increase the height first and use PIR?
2- How do I even 'strap' the joists up here? I had intended to use a twisted bent strap to hook over the inner leaf and strap along the bottom side of a joist, but having had a look up there this evening, I don't think that's possible*.
*My cavity wall (inner leaf & outer leaf) are built up to the same height. I don't appear to have a wall plate. I may have a wall brick (see ? in diagram) at each joist? See below diagram and image. Unfortunately this was the best image I could get.
EDIT: Staring more at that photo leads me to believe there may be a standard wall plate below the 'wall brick' to distribute load as per usual. As the texture of what the 'wall brick' is sat on suggests wood rather than masonry.
I want to avoid re-engaging the SE, as they've given me enough to think about...
