Started the backwall hangers project.
But before getting there I had a lot of things to take care of..
I removed the old and installed the new soundproofing door on the backwall. that was a hard one.. required modification of the wall-reinforcement of the door's perimeter with (metalic core filled with cement) studs and joist, to support door's weight. The door's frame was filled with 60kg sand. carefully filled all the gaps and seams, paint and installed contact rubbers for air tight closing.
Closed the old window using double brick walls and placed the two ventilation openings, one for clean air and the other for taking the old out.
Removed the insulation rolls from all back corners, horizontal and vertical.
Prepared all the wirings for power, lights(wireless remote switch), ventilation motor (wireless too), that will all be hidden behind the hangers once they are in place.
And finally started lining the walls with rockwool.
