We have a newly built wooden house with a wooden facade. I assume the walls, like all other houses, have different layers, including insulation. Now that we are furnishing the house inside, we are naturally putting up curtain rods, paintings, shelves, etc.
For things that require a bit more load, we are using screws that are 4 cm long. Are these screws too long to use indoors? Is there a risk they will go through the insulation and could it damage it?

As long as you are not in the bathrooms and screwing, you don't need to be afraid. Screwing the insulation does no good, but neither does it cause any harm.
But to know what kind of screw you need, we have to know what type of wall it is. If it is plasterboard with a wooden backing, you have the right screw length. If it's just plasterboard, it won't hold very well with just screws. The same goes for walls made of lightweight concrete. In that case, you also need a plug.

If it's a newly built house, you probably have construction drawings that show how the walls are built, and there you can see if there is a wooden board behind the plasterboard and where the plastic in the outer wall is located.
In interior walls, it doesn't matter if screws go into the insulation, but in the outer wall, you don't want to make holes in the plastic foil that sits behind the boards. Often, the plastic is placed inside a thinner layer of insulation, but not always.
If you find a stud to screw into, it doesn't matter if you go through the plastic.
Bathrooms are a chapter of their own and require silicone in the hole before the screw is set to ensure the sealant layer is intact.
