As part of renovations to our home we chose to replace existing aluminium electrical wiring with Copper wiring. We also wanted to replace the original R7 insulation with something better (R14 or 15) to minimize heat loss.
The issue we have now is that with the walls open the contractor has run a whole bunch of wiring through the wall studs. This poses a challenge with how to properly insulate the walls. We are concerned the insulation may not properly fit into the space and I understand we need to be careful that the insulation does not get compressed which will compromise the R value.
Hoping the experts from the forum can suggest how best to handle this scenario. Thanks for all the help with our questions!
EDIT - updated photos below. Not sure if this addresses some of the concerns about wires not being properly secured.
