Good evening,
I am currently planning the expansion of the attic in the extension. I wanted to clad the walls with a stud frame and plasterboard sheets and separate the upper peak as a storage room. In addition, I want to replace the gable construction with a masonry solution. But before I start, I thought I would first present my idea to people who may have done something like this before and have relevant experience.
First, I will describe the current situation and then explain my ideas. I would like to add pictures later, but that will happen only afterward. It is a bit dark up there at the moment.
The first important piece of information is that it is a semi-detached house where the attic is divided so that each side has one masonry wall and one rafter side. So a triangle with a 90° angle in one corner.
First, I would like to install a kind of intermediate ceiling to create the upper peak as a storage area for odds and ends like Christmas stuff and the like. My idea was simply to build a wooden stud frame on one side and create a basic structure with cross beams between this and the roof beams (rafters). I would cover this from above with an OSB board and finish the ceiling of the attic from below with a battens and plasterboard construction. As access to the area, I would plan 2-3 inspection hatches with dimensions of about 60x60 cm or so.
But now to my "problems" with this subtask: should I insulate the rafter spaces all the way to the top to save myself the effort of insulating the intermediate construction, or does that make less sense? And the second problem would be, when building the partition wall (between the neighboring house and ours) for the drywall (actually only a facing wall), do I still have to use a vapor barrier foil, or can I just set up the stud frame, put in insulation wool (which also reduces sound), and simply clad it with plasterboard sheets?
And now there is another task, the gable side. At the moment, it is a wooden construction insulated with mineral wool, covered from the outside with boards (presumably Eternit or similar [I know possibly asbestos-containing]). I am wondering how best to design that area. I would like to install a window there to have an additional light source (in addition to the roof window on the rafter side).
My two ideas are:
A: I remove the boards, insulation, and so on from the outside. Check if the beams are properly positioned for my purposes and are in a reasonable condition, create the space for an installation window by possibly modifying a part or similar. Then I apply a foil from the outside and seal it to the beams on three sides, install the window, build a basic structure of battens, and clad the side with wooden slats (I cannot remember the correct term for the external cladding of some houses from the outside). Afterwards, I insulate from the inside again with mineral wool and apply another layer of foil, mount battens on the beams again, and clad it from the inside with plasterboard sheets.
B: I remove the whole construction and build up the gable with stones, apply insulation on the outside, put on a mesh to avoid cracking, and plaster the whole thing with rough plaster or similar. And from the inside, I would simply mount battens on the stones and then build plasterboard sheets to lay cables behind them most easily.
I hope the whole thing was not too much information at once. If it is easier, I could split the whole thing into two topics (intermediate floor and gable).
The whole project is still in the preliminary planning phase. So some time will pass until implementation. But you still want to collect ideas.
