ᐅ How does insulation in brick construction affect the indoor climate?

We are considering three building options: timber frame, solid wood, or a brick house.
Many timber frame manufacturers, such as Griffner, advertise that their indoor climate is especially good because only wood is used in the walls and they are vapor-permeable, allowing moisture to be released effectively.
I have also heard several times that bricks are very good for indoor climate because they conduct moisture well. But here is the question: What happens if external thermal insulation is added on top of the bricks? Additional thermal insulation is probably standard by now. But do bricks retain their beneficial properties then?
And is there a reasonably neutral source on the topic of indoor climate, heat, and sound performance for timber frame versus brick versus solid wood?

Additional thermal insulation has probably become standard by now. I’m not quite sure what “standard” means specifically for Austria. In particular, I don’t know which equivalent to the “Energy Saving Regulation 2016” applies there, if any.

If you put aside the naive image of bricks (handmade from freely roaming cows’ clay lumps), they are no longer the only true “organic whole grain bread.” The differences between wall materials are less dramatic than their proponents and opponents make them out to be. Besides, the plaster is just as important for the indoor climate as the wall material itself.
Whether carving a house out of a whole tree trunk is truly “eco” is something I would rate with a giant question mark 🙂

But do bricks then keep their good properties? Any property a brick has can only be transferred directly (or via the plaster and indoor air) — not to an insulation board, and not through it. Any specific property essentially remains “stuck” within the unrelated material.

I always imagine that fresh air from outside must be better than air diverted multiple times through ductwork. True air is always best “analog,” I agree with that ;-)

There is no reason to assume that the ducts would become systematically or fundamentally contaminated or even microbiologically infested. Such conditions simply do not occur. Unhealthy mold growth in single-family homes is orders of magnitude lower (practically excluded) when using controlled residential ventilation compared to houses without it — mold can certainly develop if the occupants are not careful.
All other air quality parameters are always better with controlled residential ventilation than without, unless windows are kept open continuously.
Does anyone ask the same question about cars (duct system, filters, air conditioning)? That would also have to be extremely unhealthy (apart from NOx emissions, etc.).

Are there any objective sources of information about the advantages and disadvantages of timber frame, solid wood, and brick construction? On the internet, people usually praise the building material they have themselves.
But what is the reality when it comes to summer heat, sound insulation, and indoor climate?

Bieber081524 Jul 2017 09:44Just enter “room acoustics and building sound insulation in Berlin” into any internet search engine of your choice! Unfortunately, linking is not allowed in this corner of the web. Hopefully, that is objective enough for you.
Regarding “summer thermal protection,” you can actually find objective articles online as well. Just a note: brick is a vague term, as there are many different types.
Indoor climate … Yes, that might be more difficult to find something factual and objective about. It is more subjective and often influenced by myths (such as “breathable walls”).
Otherwise, have a look around your local library!
