Hello,
I am completely new to planning a new building. In this process, questions about the fundamental building structure quickly arise with construction companies. Unfortunately, I could not find all the information on the internet, and apparently, these topics are also controversially discussed among professionals.
I want to build a house with a floor area of approximately 10x10m, 2 full stories, and an attic.
The attic is not to be used as living space but for storage of items such as clothing. It is important that there are no puddles caused by condensation or mold.
I am not a big energy-saving fanatic. I think the current standards for new buildings are already set quite high. High costs for additional insulation measures can hardly be amortized anymore. Therefore, my maximum target is KfW70, unless the financial effort is unexpectedly not so high J
For the building technology, I would therefore tend more towards a gas condensing boiler, solar thermal system, and central residential ventilation with heat recovery.
So now my questions:
Exterior Wall:
Tendentially, I would prefer a single-shell wall structure. That sounds more favorable regarding the dew point, etc., and I also think that simpler solutions are often less prone to errors. With thermal insulation composite systems, the walls become too thin, and if they are damaged by awnings or wild animals, you get problems with moisture, etc.
Is that correct, or do thermal insulation composite systems offer great advantages?
What are the differences between all the different bricks – above all, are the differences significant, or is the decision essentially: with/without thermal insulation composite system and then the thickness of the wall?
Roof shape and insulation:
In principle, I am planning a hip roof (city villa) because I want two full stories and do not want to live under a sloping roof. Usually, insulation is offered on the upper floor ceiling for this. I have read that this often leads to puddle formation due to condensation.
In addition, I want to store things here that do not like moisture. Another point I have in mind is that I do not want to use the massive ceiling to gradually install electronics such as presence detectors, ceiling speakers, and other sensors to gradually integrate “smart” building technology. It is important to me that this can happen gradually, as you do not find enough time at the beginning J This electronics is on the one hand sensitive, and on the other hand, I do not want to work around the thermal insulation, as I would certainly damage the vapor barrier, etc.
An alternative would be roof surface insulation. The rafter insulation seems to be the safest here? But it has the disadvantage of being expensive and problematic in terms of sound insulation. How are the other options, such as insulation between rafters and under rafters? I cannot imagine that these can be well applied to a hip roof, with all the beam clutter?
In addition, it is apparently quite expensive to insulate a hip roof. A gable roof might be cheaper here and also easier to handle in terms of structure. It also offers more storage space and the possibility for wall windows. Perhaps including insulation, it is no longer more expensive than a hip roof with insulation?
