As i said earlier, the Room i wanted to build my Shak in was directly under the Roof so it was very good for my Project.
The only Thing i had a hard time is to figure out how to get the cables from the outside into my Shack.
I knew i had to drill a hole into the wall but there was ine problem. I had no idea how thick this wall was and what was in that wall.
I meassured the approximate thickness of the wall and decided to drill a small 5 mm hole throu that thing to check whats inside…
The drill wennt right throu and now i knew that there was no brick inside the wall.
The wall consists of a 20mm plasterboard, 25mm hardwood, 20mm air (very easy to drill :)), 150mm wool, 20mm woodboard and 80mm styrofoam.
So i bought myself a 75mm wooddrill and drilled through the plaster and the furst wood layer. I then used a stick to put away the insulating wool.
When the drill arrived i cut a bigger hole from the outerside into the wall. The holes didnt match 100% but this was not an issue because the wool was flexible.
I glued the plastic pipe into the wall with some construction foam and put a cap on it so the wildlive wont come in.
