Cavity 150mm looking for low energy Wall ties

[John McClean]

I am looking into wall ties with a low thermal conductivity, lower than steel ties. Does anyone have any experience of them, or get an analysis done on how much energy they actually save. What types are there available on the irish market, performances and costs? If you are going with a max cavity of 150mm do you need extra wall ties than the old standard 100mm cavity wall? If you have any recommendations?
