ᐅ Timber House: Wood Cladding vs. Rendered Facade (Wood Fiber Insulation Panels)

Good morning everyone,
Yesterday we met with the first company concerning our house planning.
It will be a timber frame house.
The company offers two types of exterior finishes: wood cladding (available in several versions) or a rendered facade.
The (standard, not premium) wood cladding costs about €40 more per square meter (approximately $43 per square foot). This results in an additional cost of around €7,000 for our currently very rough planned house.
We are generally more inclined towards an untreated wood cladding instead of a rendered facade. For the following reasons:
- We like the appearance.
- With a good roof overhang, I won’t need to do any maintenance on the facade for about 60 years, so it will almost outlast me. (We don’t mind the natural aging look)
- It is the most natural (ecological) material (German larch).
Now we are reconsidering if this is the right decision. Here are some points to consider:
- How maintenance-intensive is the rendered facade? It uses reinforcing mesh. Can I expect that other than repainting every 10 to 15 years (which we would do ourselves), there is no other work needed? Or is cracking a likely issue? I can’t judge the use of render on wood fiberboard panels.
- We often hear about algae growth on facades of well-insulated houses. Does this typically only affect houses insulated with synthetic materials, or also the type of house we plan? Only mineral-based paint (preferably KEIM or Sto) would be used.
- How much more ecological is the wood cladding really? The material is natural, but the amount needed is noticeably higher than for a rendered facade.
Perhaps someone can share some suggestions or explain their own choice and the reasons behind it.
We do not necessarily want a wood facade, but we find it more attractive and see advantages in the aspects important to us (appearance, ecology, low or no maintenance). The question is whether all these points hold true in reality.
We have also considered a mixed solution: wood cladding under the roof eaves and a rendered facade on the ground floor. Are there any disadvantages to this approach?
I look forward to your replies.
Best regards,
Specki

I think that in timber frame construction, weather protection and thermal insulation should be separated. Therefore, a wooden facade.Interesting point of view. However, in timber frame construction, the vast majority are probably finished with a plaster facade. Likely because it is more cost-effective and not everyone wants a wooden facade.
