  • am going to measure the depth of my joists to the top of the battens and order PIR board to fit.

    to stop the rodents returning and making it home again I've ordered some 6mm wire mesh and will staple it up as a barrier at the end of each joist run to block access to the insulation cavity between joists. coupled with closing up the possible entry points I can see along the outside edges with steel wool and foam hopefully it'll be enough to discourage their presence again.

  • Can you go any smaller than 6mm? A mouse can fit through a 6 or 7mm hole, so that will stop rats but not mice.

  • i was going to double up the layers which should make it much less possible and then I may hit it with a smear of expanding foam just to close it up.
