If you are interested in a prefabricated house, ask one question above all: Can I live there as comfortably as in massive houses? How good insulation and sound insulation in prefabricated houses can be and what you should pay attention to, you will find in the following article.
Where are the differences?
Even when it comes to soundproofing, the "stone-on-stone" design is superior to the prefabricated house: pay attention to wall widths that are as stable as possible and later to a room-filling interior - a soundproof house does not necessarily indicate quality and stability.
The thermal insulation
The consequences of a poorly insulated house are devastating: Not only the living comfort suffers massively, but also the energy costs exceed any bearable measure. Poor insulation also means less durable: Due to the resulting mold, the house is properly "lazy". As you can see, good thermal insulation pays off in the short and long term.
Is your prefabricated house supplier member of GDF (Gütegemeinschaft Deutscher Fertigbau)? A good sign, since here tests for tightness are mandatory. Additional security is provided by a RAL-approved prefabricated house, which also guarantees efficient thermal insulation.
Have your prefabricated house supplier carry out a blower-door test: air is blown in through the front door; Leaky points can thus be detected. And do not forget: you are legally entitled to a properly sealed house.
The sound insulation
Whether the sounds of the next room, climbing the stairs or the street: Nobody would like to hear that through clanking walls. Even prefabricated houses can be sound-proofed with a few simple methods.
One of these is the decoupling of components: If you attach suspended ceilings with spring rails to the wooden beams instead of slats, the number of touch points is reduced. The installation of "sound absorbers" such as concrete slabs or solid bricks in ceilings and walls also noticeably reduces the propagation of sound.
You can also solve this problem with stairs: Continuous impact noise protection prevents vibrations when entering and therefore also a large part of the noise. So you notice: Good soundproofing can also be retrofitted; but the better the "basis", the more effective the whole thing is.Tips & TricksYou have it in your hands: Pay attention to a qualitative assembly; It will save you a lot of work in hindsight. And if it is "too late": You have a number of options to retrofit sound and heat insulation.
Overview - what can I pay attention to?
Here you will find a "checklist" that lists some sound and heat protection criteria. After all, there are ways to improve both with hindsight.
- Is the facade insulation correct? If not, a retrofitted ETICS (thermal insulation composite system) can help.
- Is the roof well insulated? In case of doubt, a so-called Aufsparrendämmung be attached, for which, however, the entire roof covering is removed
- insulation of the top floor ceiling: If the roof is too complicated, thereby a lot of energy can be saved.
- The façade also plays a role in sound: if the insulation is at least 15 cm, it can easily keep up with solid structures.
As you can see, well-insulated prefabricated houses are not only possible, but perfectly normal nowadays. They can provide you with a living comfort that can hardly be distinguished from solid houses.
