    generally u-vales tend to be lower ( toward the 0.1 figure, or less) the less compact the building. basically the more exposed wall and roof areas you have the the lower u-value you'll be looking for. can you maybe outline roughly what the difference in the two sip construction types are? and whether either or both are supplied with reflective membranes inside and out?

    I'd suggest you go for a breather membrane rather than a vapour barrier in that location. vents through a 600mm stone is easier said that done - any hope BC will allow you forgo the cavity and go tight to the wall with the stud. With the render in good condition external your risk of condensation reduces significantly. +1 on MVHR

    Gaffer tape is not something I would suggest using in my retirement bungalow - nor in any home as a primary air barrier

    vc foil should be taped to adjoining vc foil - be that on underside of rafters+ above that plasterboards layer, as well as brought between floor areas- not to be stuck to plasterboard, chipboard or cut off

    Super helpful guidance @JSHarris . As you say though and I fear, having worked on many low energy and passive 'principled' new builds that many mvhr systems are ill-fitted and ill-commissioned causing unnecessarily noisy, energy hungry and dust trapped ducting far from what was designed.
