A little late discovery, but after the underfloor heating coils were laid, I found through the gaps that exist that there are missing filled compartments in the joists where insulation has been sprayed in.
A hand-drawn diagram showing floor insulation with missing sections highlighted in red, illustrating an issue with underfloor heating installation.
It is crawlable underneath as we have a crawl space.

So far, the rooms are done

How can we fix this?

The unfortunate thing about this is that the company/person who did this had an accident and is not able to communicate. So my carpenter doesn't know if we can continue from above or if it should be fixed from below.
 
Got a tip from an acquaintance who works as a carpenter to lift off/up the outer loop of the underfloor heating pipes, drill holes, and fill. The cut-out holes are plugged. The disadvantage of this is that we perforate the plastic that lies between the grooved underfloor heating sheets and the plywood.

Have you paid?

Yep, I have. I'm well aware that you shouldn't pay upfront, but both the carpenter and I should have discovered this beforehand.

If the carpenter performs the completion, the warranty also doesn't apply.

The person who did this hasn't been in an accident and is likely fully capable of speaking but is ghosting you because you've paid.
It's likely over, you'll have to fix it yourself...

Nope, no ghosting. Several people around me know him and yes, he's been in a bad situation.
It's not always foolishness at constructions, but it's sad he didn't check his own work.

You could say it was very timely to first get paid for the bad job and then get into trouble.

I have read your bitter comments in other threads but that's life, and in this case, he is actually in the hospital.

I was hoping for more creative suggestions, not to be dragged down.

If it is not addressed, you will likely get substantial thermal bridges there, right?

What kind of insulation is it, is it Hunton?

If it's possible to drill holes from above, that sounds like the easiest solution. Can't the holes made in the plastic be sealed with tape?

I would probably go with that suggestion.
You can tape the holes.
 
Still air does not transport either warm or cold air.

How large are the spaces really, where there is no insulation?
Not cubic meters, right?

The uninsulated spaces aren't 100% airtight, right? So it doesn't become completely stationary, does it?
 
Guarantees are often just nonsense. Fill the void and move forward in life.

Well. It probably won't be significant but rather minor. TS should consider doing nothing.

Could one have "padda" to spread out the loose fill a bit?
