hi.first post.great site.awesome knowledge thanks to members like dave,sir ramic and others,so thanks guys.
i have a question regarding.subfloors.i think the minimum thickness is 15mm(18 best),screwed at 300mm centres(150 best),i relise this is dependant on distance between joists ,im just talking typical.this isnt a job ive got,just clarification.
so which of these is best/correct...
1.18mm ply + decoupling membrane
'or'
2.12mm ply + 6mm hardi+ decoupling membrane.(would membrane be needed with hardi?)
'or'
3. combination
also with the use of hardi and/or membrane does bs mimimum not matter as hardi is strong ,and decouple would counter movement.
i know there was something else ,this is my 3rd time writing as keeps getting deleted:mad2:
