In this respect, I assume that my example manufacturers Meierhaus and Schulzehaus belong to the same faction. Whether sausage or cheese foil, chocolate or raspberry insulation is irrelevant here, because it does not shift a single window opening, does not affect ceiling spans, and so on. The advantage of choosing a non-stone architect for a wooden house thus remains fully intact. The timber frame panel builders practically invented the thermal insulation integral system; a thermal insulation composite system has no place on a timber frame panel construction. Here, I would draw the gray area boundary between "economy" and "wannabe with ascendant fake."
That is precisely the big mistake. One uses a 160 mm stud frame and then slaps on 1 mm EIFS (even explicitly mentioned on their homepage, a small company with 110 million turnover), the next has 200 mm studs, and so on and so forth. For years, manufacturers have only differed in the thickness of the Styrofoam they put on their timber frame walls.
330 mm wall thickness is really the cheap version. 360 to 420 to 440 mm, that’s where the differences lie afterward. And when then a 1-3 HOAI is planned and the structural engineer comes, it can get interesting. Because then the price also becomes decisive at some point. That is also the great danger of the "dough resting period."
If I may quote another manufacturer: between 360 and 420 sqm, there are 5 sqm of living space. These can perhaps be decisive, alongside the famous 15,000 euro additional costs, or maybe not.
