No. I hadn't that foresight. What , apart from falling down!, are these issues. I have seen it mentioned before in threads.
I have seen 200mm cavity houses, big ones, with 100mm inner and outer leaf, and I know that doesn't mean it's alright, but is someones insurance goin to come under pressure down the line!
i have sourced basalt wall ties certified to bsen845-1. this should reduce thermal bridge factor at this point
Just sent you pm with details, Syd.
Maybe you could check it out and give us a bit more knowledge?
I'm using Aeroboard Aeromark Platinum 140mm wide to suit a 150mm cavity, [broken link removed]]
I thought that the Aeroboard type cavity wall insulation wasn't certified anymore on new builds, Only extensions to older houses, No?

You might be correct for Aeroboard's old range, but I don't think there's any problem with certification on the Platinum range. As it happens, my engineer reckoned using full fill bead insulation would be a better option in the walls, so I'm going to do that instead.
have you anyone certifying the build?? their insurance must cover it.
if you have a builder, is he homebond registered? Homebond will NOT stand over any cavity in excess of 150mm.
if so they must certify compliance with the structural elements of the building regs, and a 100 block - 200 cavity - 100 block type construction is extremely 'iffy' without specific structural design and calculations. If the inner leaf was 215 then the 'risk' is greatly reduced and the stability is greatly increased.
