Hello
I have a house from '43 with exterior walls made of about 15 cm timber beams with caulking in the joints. Otherwise uninsulated and with vertical wooden paneling on the outside.
I need to replace the facade (and windows) but have been advised not to add extra insulation as it would do more harm than good.
The issue is that during winter, it can be seen that it leaks so much heat that the thermostat for the boiler shows two degrees warmer than it actually is outside. When it's very windy, the temperature can drop to as low as 1.5 degrees indoors.
It feels unnecessary to invest in proper windows if the rest of the house leaks like a sieve. The house has natural ventilation. Is that the only reason additional insulation is not recommended? Can it be resolved with simple exhaust ventilation?

I would say that the most important thing is to make the house windproof and to properly insulate the attic floor.
I think your wall construction is quite unusual for a house from the forties; many houses from that time have standing three-inch planks in the exterior walls.

The best way is to add insulation from the inside. Then you can complement with a vapor barrier on the inside to prevent moisture problems in the wall. This will also fix the air leakage. If you insulate from the outside, the dew point in the wall shifts and you will have a vapor pressure from the inside that in winter pushes moisture into the wall, which is not recommended for this type of construction.
Hello.
If the house has a timber frame, clay plastering, wood fiber insulation, and other similar natural materials are very pleasant to work with. You get a house that can breathe and handle moisture much better than with plastic and fans.
It is customary to insulate timber houses externally with wood fiber insulation, then wind barrier, air gap, and facade cladding.
There is an enormous amount of information on the internet. But interesting with 40s timber houses
Feel free to send a picture, and we can give some suggestions.

TS seems to have a house in 6" timber, do you @heimlaga think Charlotte is on solid ground when she recommends adding insulation from the inside above?Charlotte Andersson said:
