We have chosen “OSB platte” 12mm as our inner wall. It is not only cheaper but also very good in preventing moisture. Before we putting up the wall, we have put on a tape from inside where the framing woods (KVH Holz) are.
For the side where the wiring is, after putting the black tape, we have added a layer of wood on top before putting up the “OSB platte”, so it creates some space for all the cables between “Dampfbrense” and the “OSB platte”
We have done quite a lot in the week 4. One of the most challenging part is wiring. I have done a lot of research and someone has also explained to me how to do it. After many changes and considerations, finally I have managed it. This youtube channel – Elektroinstallation-selber-machen has helped me a lot in understanding. We only do the wiring by ourselves, we will let the electrician to finish the rest of the connection.
We have only done wiring in one side of the wall. The other side where the cupboards and staircase are, we will lay the cable outside of the wall, all cables will be hidden inside or cupboards. For toilet area, we will lay the cable inside the separated wall. Someone told us that, it is better not to lay any cables or water pipes in between the insulation and framing, I have seen many people do in this way during my research. Just in case, we need to repair any cables, we don’t have to open up the whole wall and also it is better to have a well sealed wall with complete piece of insulation inside the wall.
