D.M. Procida coughed up some electrons that declared:

Do these need to be done in any particular order, if they're being done
at about the same time?

The insulation people said it doesn't matter as far as they're
concerned, but will new insulation interfere with the work to install
the new cavity ties?

Hi,

One method to replace cavity ties is to drill in from one side of the wall
and insert new tie rods at intervals. I don't know the details, but I
assume it involves a textured rod and glue.

I can't see it mattering which way round it's done.

Cheers
