    Steel is 17, I see carbon fibre at 0.7

    Anything in between and what's the price difference?

    Hard to see any material performing up to the required spec as it's a challenging job to be a wall-tie. I did wonder what a thermally-broken wall-tie would look like - suppose CF is the best they currently can do considering the requirements.

    Those above are not carbon fibre. Carbon fibre would work, but likely costly. They are Basalt Fibre (hence BF), basically fibres similar to rockwool in a plastic resin.

    The other option is to use a slim tie. Which would be mid range performance. There is little point using an aluminium tie that is half as conductive, but twice as thick.
