    My S.E has told me I need to have windposts in several position for wall length (wind load) and large openings (structural support around bi-fold doors). I am building a 300mm fully filled cavity with Teplo type 2 ties and to put steel links between the leaves is not good thermally, although they might just prevent the house falling down. I have looked at some standard types from the likes of Ancon and they all tie on to both leaves. A U shaped post in the middle of the cavity (fixed to footings) and tied to the leaves seems to offer the best thermal performance as it would be in the middle of the insulation, but not ideal.

    All the windpost systems I have seen are either built in to the inner leaf, bolted to it or sit in the cavity. Is it possible to fit a windpost to the inside face of the outer (brick) leaf, bolted to the foundations and supported by the concrete infill (>1m). I could then perhaps add addition Teplo ties to strengthen the bond between the leaves.

    Any ides?

    Yes, might need to ask a SE to prove it is OK

    I rather fancy that an angle iron might be good enough and it would look like a movement joint in the outside skin.

    Have you looked at joint bed reinforcing (Brickforce) to see if this may be a more practical / cheaper solution?
