    Hi,

    Can someone tell me the 2011 Building Reg U-Values for the following (or point me to a document which has a plain and simple table describing them):
    • Foundations
    • Walls (I found mention of 0.21 W/m2K for walls)
    • Attic
    • Windows & Doors

    Thanks!

    for new builds theres no longer prescribed so called 'minimum' u values.

    SEE SECTION 1.3.2 HERE

    if it is a new build its quite possible that lower u values may be required.
    Compliance is now assessed as an holistic overview of all specifications rather than by prescribed individual elements.

    Table 2 here shows how U Values , Air permeability and how you heat the house ( what fuel)
    all combine.

    It is no longer enough to ask "what U Value" .
