Vapour Check and Drylining

    I understand that there should always be a vapour check on the warm side of the insulation to minimise condensation issues in the insulation, and the options are vapour barrier as part of the insulation-plasterboard or a polythene sheet. I understand that, for preference, this vapour check should be sealed to the underfloor damp proof membrane.

    But, being a wall in a domestic property, the vapour check is usually going to have holes in it— radiators, electrical sockets, curtains, picture hangings, etc.

    So my question is, do relatively small punctures like these make any significant difference? And if so, what should/can I do to mitigate the harmful effects?

    Thanks.

    1. Yes, can do.
    2. a. create a service cavity inside the barrier,
    b. ensure adequate heating & ventilation
