Soffit insulation, wall plate cavity closers

[WWilts]

Builder thinks loft insulation spilling over into soffit space should be sufficient for heat insulation purposes.

Is that true?

 

Cavity closer will be fire sock Rockwool. Except where two small lintels are close together. Between those lintels (~50mm gap), builder proposes to use foam to close the cavity. Will foam suffice to keep EPS beads in the cavity when they are pumped in?

NO!   In the illustration it is only possible to have a maximum of 95mm over the corner of the wall plate. 
 

I have 400mm in that location ?
