Threshold on floating floor

[Derbyboy]

How should I proceed to get it right? I want to fix the threshold

the floor is floating so I can't attach the threshold to the floor.

When I installed the thresholds at home, I first drilled holes for the screw through the parquet down to the particle board, then an 18mm (another size works just as well) through just the parquet.
This creates an expansion joint around the screw.

This has worked well for at least 6 years now.

 

[Derbyboy]

Ah, that's of course an option. However, I would like to avoid screws and instead glue the threshold.

 

[Allmänobildad]

You can do that with regular mounting glue, but then the threshold will lock the floor against the door frame. It should not be an issue as long as the expansion gap is sufficiently large on the other side of the floor.

 

[Derbyboy]

You mean that if there is movement margin at the end of that line, it works to wedge the piece sticking in under the door.

So if there is movement margin at the end of the red and green arrow?

Double-sided carpet tape.

[Derbyboy]

Yes, but such a tape also prevents the floor from floating.

 

[Utdelning]

Sure, but such tape also prevents the floor from floating.

How so? The tape is elastic. Often used for rails on floors, etc.

Mounting glue definitely prevents movement in comparison.

 

[Derbyboy]

Yes, in those cases the rail moves with the floor, but in this case the threshold cannot move since it is taped and wedged (between the frame).

 

[Allmänobildad]

So if there is leeway at the end of the red and green arrow?

No, towards where the tape goes downwards to the right in the picture

 

[Derbyboy]

Ah of course, yes in that direction there is a rörelsefog but the distance is maybe 7 meters.

 

[Derbyboy]

I think it would be an option to saw a channel just inside the threshold and then glue the threshold in the remaining part.

 

[Allmänobildad]

Ah so of course, yes in that direction there's movement joint but the distance is maybe 7 meters.

The greater the distance, the greater the joint required.

The thing with the rail is smart! It should be possible to make some homemade version of kährs T-list, but with the threshold.

 

[Derbyboy]

Don't you believe in making a fig under the threshold and then gluing the threshold Ibsen part that remains?

The part that remains is so relatively small that it can be fixed in place in the chip underneath.

 

[Allmänobildad]

Yes, you can do that! Then the single small floor piece is attached to the groove, and the threshold is attached to it without locking the rest of the floor.
