Mistake, advice needed . Insulation in cavity stops at DPC.

[connick159]

Hi, walls are all done, roof on, windows all fitted and I've just realised the brickies didn't carry the cavity wall insulation (PIR board) 150mm below the DPC.

Stressing out a bit as too late to change it but about to put down floor insulation in prep for UFH and screed.

I'll be putting perimeter insulation before the screed but very concerned about cold bridging now.

Are there any options for blown insulation into the bottom of the cavity? I still have access in spots where door and window cils not yet installed.

Am I worried over nothing or is this a big oversight and will leak heat unless resolved?

Thanks.

I would think blown beads is am option drilled from outside. Look into it

We intentionally build and insulated the cavity for 500mm below dpc with bonded bead to mitigate bridging.

Thanks for the updates, what company did you use for the beads?
