    hello folks,

    the first flue is a balanced flue from a grant multipass boiler which passes through a cavity block wall. There is 2 inches of aeroboard in the cavity. What will I use to surround this flue in the wall?

    The second flue is a twin walled external insulated flue which passes through the same wall, coming from a range. What's used to surround the flue in the wall?

    Many thanks.

    The first one didn't really need anything
    Knock out a hole put flue through and then cement up to it.
    The one from the range providing it's solid flue the flue should go through the wall at a 45degree angle and the flue should be sleeved and insulated around then filled over with cement
    What ever make of flue your using the manufacturer will have an installation guide
