Hello everyone,
I hope this is the right place to ask my questions. Despite some research and discussions, I have not yet been able to find a definitive answer.
About the project:
We are building a semi-detached house. Currently, we are deciding between a brick prefabricated house and a solid wood house.
A common drawback mentioned for the solid wood house is sound insulation, especially between the floors. Does anyone have experience or advice on what to pay attention to in this regard?
Furthermore, the heat protection of both construction methods is not entirely clear to us. This is particularly important for the roof structure, as we plan to have the bedroom in the attic.
Does anyone have experience with this, keyword: summer heat protection?
Many thanks and good luck

I hope you know your co-owner and their preferences – otherwise, I wish you the best of luck and recommend reading the thread by @goalkeeper. Normally – although the search function here currently only works at a third-division level again – I would also suggest the search term "11ant semi-detached house." In short: building one half as if it were a standalone house is generally not one of the smartest plans. But I don’t want to repeat myself at length here – perhaps a web-wide search using the above search term will also lead you to useful information.

Soundproofing between floors is not an issue with solid wood. I think, as is often the case, it will depend on the floor construction.
In our case:
Solid wood ceiling
Loose fill insulation
Floating screed
Of course, if a herd of elephants stomps above, it will be audible downstairs.

One common concern about solid wood houses is soundproofing, especially between floors. You should consider that this may be all the masonry builders can come up with... As mentioned before, soundproofing mainly depends on the floor structure. There are several options available.

Any tips on what we should pay attention to? Visit a show home of your solid wood house supplier and test the soundproofing yourself. Besides the type of floor construction, the architecture also plays a role. For example, open-plan designs tend to be louder.

Furthermore, the heat protection of the two construction methods is not entirely clear to us. This is especially important for the roof structure since we plan the bedroom in the attic. Here, it is less about the building material itself and more about the roof construction and the size of the windows – and whether the sun shines on the roof above the bedroom all day long. If you are sensitive to heat while sleeping, an air conditioning solution might be necessary.

knalltüte20 Jun 2020 20:10Hello, we are also building two semi-detached houses as solid wood houses. Construction will start soon.
We have thought more about summer heat protection than about heating demand. Modern houses are airtight and energy-efficient. Climate change is happening, and it will likely get warmer rather than colder.
Mass is important for summer heat protection. Therefore, our relatively thick above-rafter insulation (20cm (8 inches)) will be made of Gutex wood fiber insulation boards. This helps with the roof.
In addition, we will be able to cool 2 to a maximum of 3°C (3.6 to 5.4°F) using our brine-to-water heat pump. That also makes a difference. (It will probably be an S1255-PC from Nibe for each semi-detached house.)
Oh, and external venetian blinds also have an advantage over internal blinds here. Window size, as already mentioned, also plays a role.
For us, a solid wood house means glued laminated timber (glulam) plus insulation, not log construction. The latter is hardly ever approved nowadays (my parents as well as my sister and her husband have log houses. At that time, solid wood around 12cm (5 inches) without further insulation was enough. They retrofitted 8cm (3 inches) of wood fiber insulation boards later.)
According to the architect, sound insulation is not an issue with 12cm (5 inches) glulam ceilings plus a suitable construction. He is only concerned about sound insulation in the separating wall between the houses. This wall is planned to consist of 10cm (4 inches) glulam, Fermacell boards, 4cm (1.5 inches) of insulation/fire protection wool, and then the same layers in reverse order. He would prefer a sand-lime brick wall there.
There was already a question about the builder of the other semi-detached house. You need to come to an agreement because using different materials for the roof or walls can cause problems.
Urgent recommendation: find a shared architect who is also an energy consultant. Currently, there is a lot of funding available for KfW40(+) standards, which are easier to achieve with wood (thinner walls) than with monolithic construction.
