    Hello! What is the convention for modelling thin foil insulations in PHPP please?

    Thanks in advance for any help.

    Hi Kirsty,

    I recall that Dr Feist suggested considering that you'd need about 200mm of foil insulation before it actually achieves the required performance (and even then you'd need to think about thermal bridging at compression points, dulling of foil reflectance, etc.)

    …Basic idea: not a good idea.

    HTH,
    Mark
