Hello,
Finding out about wooden houses, I am surprised to read everywhere that wooden houses do not have thermal bridges.
When I see that the insulation is placed between the wood studs, the studs themselves are sources of heat loss.
What do you think ?
What are the remedies?
We look forward to seeing you!

thermal bridges
hello, to answer very quickly,
by definition wood is a natural insulator, so with wood no thermal bridges.
then if there is a loss, you must see the concrete slab side or space between the wood frame.

Hello
The insulation between the studs is more insulating than the stud wood
Pine thermal conductivity: 0,36 (Wm-1K-1)
Thermal conductivity of glass wool: 0,04 (W · m-1 · K-1)
hence the term thermal bridge by the studs of the frame, cold or heat will be easier to pass through the wall by the studs.
By cons if you insulate from the outside as say verdes, you create a homogeneity of your walls and you cut your thermal bridges.
For example :
The insulation between the studs is more insulating than the stud wood
Pine thermal conductivity: 0,36 (Wm-1K-1)
Thermal conductivity of glass wool: 0,04 (W · m-1 · K-1)

thermal bridges
according to all that i have just read, that will mean that in the nordic countries that i know very well, it will be necessary to change all their windows in triple glazing, since they are made of wood, and yet to watch , they don't even have a thermal bridge cutout joint, and it's still very good in homes.
it is the first time that I see that there are thermal bridges with wood, and I am of a trade of wood at the origin, it will be necessary that I review all my knowledge in this field, it is maybe modernism wants that.
good on that, I stop, and I prize you for agreeing to take my message with a little humor, as I did when I wrote it.

Hello,
Thank you for your answers.
Unless I am mistaken (in the following reasoning)
Let's assume a 6m long wall
Uprights 220x45x2600mm, center distance 60 cm
There are therefore 11 uprights, i.e. 1,3m2
Thermal conductivity of pine 0,36
the Amount has an therefore an R = 0,61
Insulation: 20 cm; 14,3m2
R = 5
Wall resistivity: 71,5 + 0,793 = 4,63
U = 4,63
We therefore see that we lose about 8% with amounts of 220 and 20cm insulation.
So there are a lot of losses.
Putting on a layer of superimposed insulation could be a solution, but at what cost?
Thank you for your answers,
Roman

You forget the high, low and chaining struts.
From memory because I am too lazy to redo the calculations, the wood reduces the performance of the insulation by 14%.
To reduce thermal bridges you can use an exterior wooden wool umbrella (some even serve as bracing).
In addition, these panels allow airtightness.
