I am going to build a small cottage, the wall thickness of 150 mm of osb, the finishing layer of metal siding.

Where to attach a windproof membrane? Before the OSB or after?

First lay in the wall 150mm mineral wool. Inside the vapour barrier, outside advice osb additionally treated with antiseptic.

Next 50-100mm of stone wool facade water repellent (it is more dense) and do without windproofing. The air gap of 50 mm, then the facade covers. The bottom of the blowing and possibly a gap on top.
