    Should window manufacturers know/test how airtight their frames are under pressure?

    for example if a house is being built with a predicted airtightness of X, should the window manufacturer be advised? and should a builder get confirmation that the window frame will offer X?

    I foresee windows being the weak link in a SIP-build?
    is this the case?

    I was under the impression they did airtight tests on samples, as there's a miniuim requirement,
    and this data was available.

    Wasn't achieving airtightness one of the reasons given for preferring open-in windows in passive-house?

    I would have thought that air pressure from the outside-in was greater than inside-out leading to open out windows being more airtight (i.e. windows pushed into their seals by wind etc) ?

    If positive on windward side, it's going to have extreme negative points on the turbulent lee side. That stuff often claimed about wind pushing inward is I think simplistic. Any wind is suck as well as blow.
