ᐅ Adding Insulation to a Prefabricated House Yourself, Affordable Polystyrene Options

Hello everyone,
My prefab home supplier is offering me a standard low-energy house KfW 70.
I have now received a price for upgrading to an insulation package for KfW 55, and I noticed that only the insulation in the roof and upper floor changes. The exterior walls are already basically at the KfW 55 standard and are not further reinforced with this package. The cost of the package is about 6000 euros.
My question to the experts is: Can I simply take the standard package and add additional insulation myself in the attic?
For example, just line the entire attic with Styrofoam since no one really accesses the roof anyway.
How do you assess this approach?
Thanks and good luck.

....First, some information you may have missed. €uro makes his living precisely from doing these calculations. That’s true, but I’m already quite satisfied if non-experts understand that with modern heating technology, without proper planning and sizing, you cannot expect high energy efficiency or low operating costs.Musketier schrieb:

That is to be expected, because reliable assessments are usually not possible, and non-experts often draw incorrect conclusions by overgeneralizing. As the saying goes, the devil is in the details!Heat pump systems are by far the most sensitive heat generators—if everything is not perfectly aligned, excessive energy consumption is almost inevitable. Even with simple radiative heating systems, for example combined with a gas condensing boiler, it is usually possible to achieve 20 to 35% better energy performance.
Since I am involved not only in planning new construction projects but also in renovating existing buildings, I notice all the major mistakes that could have been avoided with precise upfront planning.
Best regards.
