ᐅ Non-Load-Bearing Interior Walls – Which Construction Method?

Hello!
I am currently considering which construction method to use for the non-load-bearing interior walls on the ground floor and upper floor of my building project.

I would like to do a lot of the work myself during the house construction to keep costs under control...

1: Solid construction with calcium silicate bricks, plastered, filled, painted

2: Metal stud frame, insulation, OSB board, drywall, filled, painted

Has anyone compared the costs of these options by any chance?

How is the sound insulation?

I would really appreciate some experience reports.

No. You can simply check the current prices in stores yourself and get up-to-date information.

If you do it yourself, I would always recommend drywall construction. This makes the electrician’s work much easier (otherwise they have to chase channels in the sand-lime brick). Could you plaster the sand-lime brick yourself? Drywall offers an easier starting point.

What about sound insulation?

There is sound insulation. Your question is how exactly?

I would like to install the electrical wiring myself, in consultation with the electrician.

Of course, I could NOT plaster the sand-lime brick myself... at least not to a satisfactory standard...

How do the sound insulation properties of the two wall constructions mentioned above compare? Which option provides better soundproofing?

Regarding the upper floor, I recommend checking out my posts “Plan change: switching from concrete to a wooden ceiling” and (especially if the upper floor is an attic) “Lightweight walls in solid houses?”. Basically, keep two things in mind: first, not all non-load-bearing walls are non-bracing, and second, there is limited cost-saving potential in the basic masonry shell. So you might be disappointed by how little money doing the work yourself at this stage actually saves. For example, avoiding corners and junctions—and the knock-on effects all the way to roof ridges—saves more money, whereas building the walls yourself might mostly feel useful but only matches the muscle ache efficiency of other DIY tasks.

I would plan the materials individually for each wall; for example, gypsum boards are also an option. If you are a first-time DIYer, it’s better to use aerated concrete blocks rather than sand-lime bricks if you want to do masonry. But even that requires experience: the tricky part is, even with small formats (about a quarter meter layer height, block lengths of 500, 600, or 625 millimeters (20, 24, or 25 inches)), the narrow bed face is a challenge. Professionals build double-high layers here, but for a beginner that can look quite rough. Generally, metal stud lightweight construction will serve you best. It also makes it easier to add more DIY work like cable installation later on.

Sound insulation is much more a matter of construction technique than of materials.

Both materials rank at the very top. With drywall construction, you can even decide yourself how effective the soundproofing should be—by the type of filling used, up to acoustic insulation mats.

Yes. So you definitely need to discuss with your architect during planning which walls can be built in which way.

Thank you very much for your suggestions! Especially that even non-load-bearing walls are important for bracing and that the whole matter needs to be discussed with the architect!

I have noted that down.
