ᐅ Timber frame construction with effective wall assembly

Hello,

After much consideration, we have decided to build a wooden house on top of our basement (by one of the local timber frame companies). The quotes are quite difficult for me to understand, but it is clear that we would be willing to pay more for a good wall construction (with regard to durability, indoor climate, etc.).

The offers vary quite a bit; some use cellulose insulation with OSB boards plus Pavatherm or similar, while others use mineral wool in parts, and so on.

Do you have good experience with a particular wall or roof construction (in our case, above-rafter insulation) that you would recommend? Since we live on the edge of a forest, it is important for me to have something resistant to rot, mold, and insects.

As mentioned, it doesn’t have to be the cheapest option.

Best regards

What is the reason for choosing wood over stone if you haven’t decided on a wall construction yet?

If you have already chosen a company, what kind of approach does the company usually follow? Does it make sense to assign someone to a system they have no experience with?

Well, we actually got into wood through the facade… we want a shiplap cladding with a ventilated facade (sort of in the Swedish style). With traditional building companies, I was often advised against this: better to go with a plaster facade, and rounded windows don’t really make sense… Then I visited two carpentry firms, and, how should I say, everything was much more optimistic there… Always: yes, we can do that.

For us, achieving KfW70 standard with masonry and gas plus solar would already have been a challenge, but with wood, it seems to be no problem (so far).

My question is more about the roof and wall construction with wood framing. I have one quote using cellulose insulation, one with wood fiber, and optionally hemp insulation. Each system seems to have its advantages. Pavatherm is apparently used by nearly everyone for external walls, etc.

So my question is for those familiar with these insulation types who can recommend which insulation to use. I would prefer to avoid mineral wool.

Regards!

All three insulation materials work well. Depending on the local requirements (noise protection / heat insulation, structural engineering, house design), one option may have advantages over the others, and it basically depends on which solution the respective company has more experience with.

Why don’t you get advice from an architect? One to two hours of consultation fees are a small price to pay compared to a decision you might regret for the rest of your life. You don’t necessarily have to build with the architect; just get some advice!
