The last layer of the house, in German they call it Fassade. We have chosen “Nut und Federbrett Fichte” 19mm from our wood supplier. The wood is untreated, so we have to paint it over with paint that suitable for outdoor.
Before the facade, we have to use a tape called “Nageldichtband” to put on every part that we have wood for framing, it is a very strong sticky tape that can protect the black layer from each screw that we use for fixing the facade. After putting on the tape, we fixed the black layer with our left over “OSB platte”, then finally we can put on a beautiful final layer for the house.
