EWI Detail

    I am planning on adding EWI as part of my house renovation. The house is a 1970s bungalow with cavity wall construction. The cavity has been pumped with insulation at some point in the past before we both it.

    I have read in several places that the EWI should come up past the soffit and meet the attic insulation. The issue I have is that I won't be able to get these 2 layers of insulation to meet without blocking the ventilation at eaves level. The wallplate is sitting on the inside leaf of the wall rather than on the middle of a cavity closing block (there isn't one) which reduces the space for the insulation to extend.

    My questions are:

    1. Do insulate as much as I can and just accept that it is not perfect?
    2. Consider internal insulation rather than EWI?
    3. Something else. I am open to suggestions.
