whats that then?personally I used to screw in using turbo gold scews into studwork and the same for 6mm flooring grade.
Don't ever use it now as there are better products out there.
Ahem, I meant the better product than hardie Dan!!!Turbo gold screws?
They the ones with two threads on them?
I use jackoboards for almost every installation these days.
lightweight. Thermally efficient. No silica. Cheaper!
