Screws for wood fibre insulation through batten
HI Guys,
Im fitting 60mm steico woodfibre boards to the outside of the TF. These will be secured in place as per the manufactureres instructions with counter battens (38x50) and the cladding will go onto the horizontal batten also 38x50.
Instructions say to use 6*180 screws, but im concerned these will lead to cold bridging? Although they will be buried in a batten and then covered with another batten.
Would something like the following be suitable?

I've had a gander.
Our walls were 250mm cavity wall with Stainless steel ties going from inner leaf @ 4/m2 so probably a much worse situation than you are in.
Changing to Teplo basalt ties would have cost an extra €2500 over SS and would have saved...........drumroll.............. €2 per year in heating (2 kWh)
It was beyond insignificant in the scheme of things. By improving the airtightness by 0.005ACH per hour we'd have got the same improvement or pluggin
