    New house?

    If so, what is the air-tightness test state?

    2012 build. We might be putting in a window where the vent is so need a new vent. The current vent is very big so wondering what the reg's are?
    House is BER B1 and heated by gas

    In most cases a 100mm diameter hole or 150mm diameter.
    What size is there now?
