Screwable transition profiles vinyl for underfloor heating

Hello everyone,

in our new single-family house, we want to lay vinyl in the living areas on the upper floor. Now we have reached the topic of transition profiles.
We have the expansion joint in the screed behind the door frame. Here I would also install the base rail of the transition profile.
I did some research online and read that you should never screw a base rail into the screed core if you are using underfloor heating.
The problem that you might possibly drill into the underfloor heating pipes seemed obvious to me. However, we have a screed thickness of at least 7 cm on the upper floor. The pipes are max. 2 cm thick. The dowels/screws for the base profile are 22 mm long. As long as I work carefully with a depth stop, there should be no problems here, right?
I also have photos of the installed pipes, so I can estimate where it is safe to drill and where not.

Or are there other serious reasons against a screwed base profile?

Thanks and regards
Julian

I bought aluminum strips without screw holes, and printed a thick bead of silicone into the gap of the laminate, and glued the profile onto it...

At first I wanted to screw it in, but since exactly where the laminate expansion joint goes, there's also the screed joint, there's nothing to screw into. So I glued it.

By the way, baseboards can also be glued firmly with acrylic...

The problem is rather that the screed edge at the expansion joint will break off when you drill. For the screed and structurally, it's no problem, but no plug will ever hold in the "hole". I glued the base rails to the screed each time with professional mounting adhesive, that holds perfectly.

The problem is rather that when drilling, the screed edge at the expansion joint will break off. For the screed and statics, this is not a problem, but no anchor will ever hold in that "hole." I glued the base rails to the screed with professional assembly adhesive, that holds like a bomb.

Which product can you recommend? Do you have a photo of the installation?

Which product can you recommend?

We had several cartridges of "Soudal Montagepro 140" available.

Do you have a photo of the installation?

Not really. Clean the rail, clean the screed, apply a bead of adhesive to the rail, place it, align it, weigh it down with something and leave it overnight, done.
