Eaves - Should I Insulate the Area in this Photo? (and a few other questions)
Sponsored Links
Here is an image of a typical eaves detail showing how the loft insulation is linked to the wall insulation.
It would make sense to bring the insulation down so that it is covering all exposed masonry.
You then use soffit/fascia vents and eaves ventilators to allow the passage of air back into the loft.
Yes, you can knock the nails home.
Water staining is typical and commonplace. Wood can get wet and get dry again without too many problems. Preservative will help counter any wood boring larvae so will only be a bonus.
Can't see the point in fire stopping.

Excellent, all questions answered... thanks!
Fire stopping is required in all shared soffits at the party wall junction. It's a significant route of fire from one property to the next from the eaves, wall cavity, or party wall cavity. It has nothing to do with the asbestos soffits, which are not there to stop fire spread.
It needs to be a vertical barrier, and designed/fixed so that it does not drop if one side of the eaves is affected by fire.
Noses' detail there does not show any eaves ventilation tray to keep the insulation down off the felt to let air into the loft.

No mastic.
Quilt is laid across the party wall ensuring that it's not higher than the rafters. This prevents fire spread across the wall.
In the soffit, quilt is nailed vertically to a rafter to cover across the soffit void and meet up with the party wall quilt, and tie in with the party wall cavity.
The fire stopping quilt has mesh in it, so bend and fix that to keep it in place.
