The devil’s in the detail and it’s no good if the system fails because water gets in where the fixings penetrate the render. NBT specified Fisher Thermax fixings through the woodfibre insulation. The drill bit tends to wander all over the palce in the woodfibre because it’s so ‘soft’ but the Thermax worked well. Worth using stainless steel and note the plastic spacers on the RWP. Need lots of silicone carefully placed to seal back to the Nanopor render.
