Hello everyone,
We are currently building our future bathroom. The old bathroom has been completely removed, including pipes and walls.
The wall where the pipes were located was made of a 20cm (8 inch) deep steel frame, which probably does not meet today’s standards. In other words, rectangular steel tubes were welded together as needed.
We have now modified this steel frame to suit our needs. Part of the 20cm (8 inch) partition will remain so that the sink pipes and drain pipes have space there. Where the walk-in shower tray will be, we gained almost 10cm (4 inches) of space, resulting in a shower about 90cm (35 inches) wide.
The pipes have already been installed, and empty conduit pipes are in place as well.
You can see everything in the pictures.
Now we are at the point where we want to rebuild the wall. Since the entire house is built using timber frame construction, we want to construct this wall the same way. We will use wooden battens that are 80mm (3 inch) deep as the substructure, placed vertically (leaving gaps where the steel structure crosses), then we will install OSB3 boards and green gypsum board on top. Insulation material will go between the wooden studs.
Here is the first question: Vapor barrier – yes or no? Behind this wall is a stairwell to the basement (not heated) as well as a stairwell to the upper floor (unfinished).
Regarding insulation: When we opened the wall, we removed a lot of old fiberglass wool that had simply been stuffed in without any fixing. It dates back to 1979 and is probably no longer effective. Mineral wool would likely be a better option, or what do you think?
We will need 80mm (3 inch) thick insulation for the wall. How can we fix it in place?
If we just wedge it between the wooden studs, it will probably fall out again because the steel frame is still an obstacle. Would simple double-sided tape be enough?
Does the width of insulation mats/rolls set the spacing of the wooden studs? Or can the mats/rolls be trimmed to fit?
We want the edges of the OSB boards (tongue and groove) to rest on a wooden batten so that we can fix the joints properly. The OSB boards are 675mm (27 inch) wide. That means the insulation mats/rolls should be about 60cm (24 inch) wide.
Looking forward to your suggestions and ideas. Thanks in advance!
