ᐅ Solid Construction House vs. Prefabricated House

Solid construction is always the fortress (even though not even a lamp will hold on the ETICS there, but never mind).

I would by no means describe masonry houses with ETICS (External Thermal Insulation Composite Systems / thermal insulation systems) as "solid": they are usually built with load-bearing interior walls serving as exterior walls, but even with a Wonderbra, a 17.5cm (7 inch) wall remains a 17.5cm (7 inch) wall. If you want a "wall" made purely of stretcher bonds, then at least make it a full brick thick! – otherwise, in my opinion, this is just misleading the public.

By the way, similar to ETICS, you could call prefabricated wall panels "thermal insulation integral systems," because in principle, they are installing insulation vertically between the rafters—just a little something to ponder.

The longer I read in this forum, the less motivated I am to post. But I liked yours!

If I made you happy, then it was worth it – because for a moment I was actually tempted not to send the post at all: hardly anyone wants to hear the truth (that the question of which brick is the philosopher’s stone is only a hallucinated concern); the audience is mostly "tuned" (or rather misadjusted) to the truths "Faction X is right" or "Faction Y is right." But no one – not even me, haha – truly holds that view, at least not as long as it is linked by "or." Because, as one person’s owl is another’s nightingale – and that’s how it should stay.

The "nice" thing is: assuming the one true answer to the question "which wall material" has been found – then we can’t just happily and contentedly go home like Piggeldy and Frederick. Instead, the tune continues: heating, ventilation, hot water supply; welded mesh fence – hedge – gabion; did I happen to mention this month that I prefer two single gates to one double gate? *duck and run*

Indoor climate – it's hard to define, but for me, good air means being able to sleep with the window open.

Opening the window is a huge plus! Currently, the trend is toward building airtight, mechanically ventilated boxes. I definitely prefer a design that allows good air quality even when the windows are closed at times. Besides temperature, factors like humidity, particulate matter levels, odors, air movement, type of heat source, and low pollutant levels all contribute to what I consider indoor climate.

We believed that wooden constructions would perform better in this regard. This is not a claim to be “correct,” but the original poster asked for reasons behind the decision.

Phew, this is getting philosophical again... The wall structure doesn’t affect ventilation at all... No matter what the wall assembly is, you still have to pass a blower door test. In other words, the ventilation requirements are the same whether ventilation is manual or mechanical.

Your timber frame construction is just as airtight as any other modern house. Unfortunately, catchy marketing slogans won’t change that. The air quality is neither better nor worse, and you need to ventilate just as much or as little. Choosing manual or mechanical ventilation is simply a matter of personal preference.

If anything influences indoor humidity, it’s the occupants’ living habits (drying laundry indoors, etc.) or, to a very small extent, the interior plaster. The wall structure itself has absolutely no impact—how could it?

That was said without understanding the construction—better to reflect thoughtfully.
A blower door test is not mandatory.

That is unfortunate for you, because a blower door test can often help identify weak points and construction defects.

Regardless of the test (you are right, it is not mandatory but has largely become the standard), it is legally required by the energy saving regulations that the building envelope is constructed to be airtight... test or no test. Either your building envelope is airtight by definition (or as you would say, like a sealed container), or your builder is not complying with current laws...

...or we want it that way, do it that way, and are allowed to do it that way.
