Is it possible to install parquet floor without room interruption, floating?

Yes, it will be an exciting time, I'm looking forward to it. I already trust myself when it comes to craftsmanship, I have built furniture myself and even felled a tree once;) In addition, I still have 400 overtime hours

I really think it's great how you approach this. Nevertheless, 400 hours is "only" 50 days, and that's not really much in construction. How far along is your project? Often people plan things that are time- and cost-intensive, which they could have skipped, so this is my note regarding the overall thread. If you senselessly plan 10 sqm, it becomes difficult to make that up with your own labor. When I built my first house, it took me 8 years to finish, and by then I had already moved 2 interior walls because I was dissatisfied. So get the maximum help here, and then you can invest your time and energy meaningfully and where it fits well.

Tensions are of course annoying. Do you have underfloor heating? What type of wood was the parquet made of? How big was the gap to the walls in your case?

I hope you’re not seriously considering beautifying every room with a ring joint in the area of the edge insulation strips to compensate for a neglected expansion joint (?). At least you should not bridge an expansion joint across ceiling panel boundaries. When building your own home, there are plenty of opportunities ("a dime a dozen") to attempt DIY work in places where the marks of beginner quality remain inconspicuous.

Hi,

Tensions are of course annoying. Do you have underfloor heating? What kind of wood was the parquet made of? How large was the buffer to the walls in your case?

Yes, underfloor heating. The parquet was and still is oak. Exactly the same was bought again and then glued down. The buffer to the walls was the usual 10-15 mm (we installed it in very dry air, therefore the maximum distance so the wood has enough space in summer). But the problem was not touching the wall, rather probably the running of one room into the other. This way you have strips that are 5 m long (still in the room) and ones that are 10 m long (through the door into the other room). The strips naturally show different expansion behavior, because the 5 m strip has a "joint" after 5 m (it simply ends), but the 10 m strip does not. That causes tensions within the parquet. When glued down this no longer occurs.

You hopefully don’t seriously consider beautifying every room with a ring joint in the area of the edge insulation strips to compensate for a disregarded expansion joint (?).

In this case, you are not quite correctly informed for once. The parquet manufacturers do allow laying over 10-12 m and over joints. Our parquet was approved exactly for this installation scenario. And the expansion joints in the screed are largely stable. The temperature fluctuations of the screed between summer and winter are unlikely to exceed 10 degrees. Screed expands by 0.012 mm/mK when heated. This means, for example, that a screed surface with an 8 m edge length expands by about 1 mm when heated by 10 K. This should not be significant compared to the length changes of the parquet due to different air humidities. In other words, building over an expansion joint is no problem. But with floating installation it must be a uniform surface, which of course is no longer the case with rooms.

Best regards, Andreas

Hi,

A screed expands by 0.012 mm/mK when heated. This means, for example, that a screed surface with an 8 m edge length expands by about 1 mm when heated by 10 K. This is probably negligible compared to the length changes of the parquet due to varying air humidity.
In other words, covering expansion joints is not a problem. But in the case of floating installation, it must be a uniform surface, which of course no longer applies to rooms.

Hi, Yes, underfloor heating. The parquet was and is oak. Exactly the same was purchased again and then glued down. The gap to the walls was the usual 10-15 mm (we installed it in very dry air, therefore the maximum distance so that the wood has enough space in summer). However, the problem was not bumping into the wall but probably the laying from one room into another. This results in strips that are 5 m long (still within the room) and ones that are 10 m long (through the door into the other room). Of course, the strips show different expansion behavior because the 5 m strip has a "joint" after 5 m (it simply ends), but the 10 m strip does not. This causes tensions within the parquet. When glued, this no longer occurs. You are not quite correctly informed for once. Parquet manufacturers do allow laying over 10-12 m and across joints. Our parquet was approved exactly for this laying case. And the expansion joints in the screed are largely stable. The temperature fluctuations of the screed should not be more than about 10 degrees between summer and winter. A screed expands by 0.012 mm/mK when heated. This means, for example, that a screed surface with an 8 m edge length expands by about 1 mm when heated by 10 K.

Thanks for the information In the house, we would have a section where the parquet will be 11 m long and extend over three rooms. In this section, interruptions could reduce the risk of tensions
