ᐅ Temporary floor covering for underfloor heating systems

Hello everyone,

As is often the case with a self-built home, you also plan rooms intended for future use, such as a child's bedroom without children yet. Since these rooms are not really needed at the moment, it doesn’t make sense to invest a lot of money in them. But even in these rooms, everything should be prepared so that no construction dust, for example from unsealed screed, constantly lingers in the air. And maybe from time to time guests might stay who could use this room...

Painting the walls white is no problem; in fact, that’s already done!

But what about the floor?
I’ve been told that with underfloor heating, only glued flooring is suitable. However, I’d rather not glue tiles, parquet, or carpet down now, which might have to be removed after a few years if I want something different for the child’s room. So the idea came up to simply “seal” the floor somehow, maybe with a type of floor lacquer like the kind used in garages...?

I have no experience with this at all and would appreciate comments, opinions, and advice from those more experienced ;-)

Have a nice day,
Teufelchen

I would like to revive this thread and add my question.

When installing laminate flooring over a floor with underfloor heating, is a special underlay required?

Normally, you would use a standard acoustic underlay, but wouldn’t that cause condensation or moisture buildup underneath once the heating is on?

Or do you install the laminate directly on the subfloor without any underlay?
Or do you use an underlay with a vapor barrier?

Lots of questions, right 😀

That’s a good question, I’ll join in on that.

I always thought there were “combination products”? Like impact sound insulation and walking noise insulation with an integrated vapor barrier, so you just lay that on the screed and then put the laminate flooring directly on top.
(By the way: impact sound insulation only refers to sound transmission downwards! Walking noise insulation relates to sound transmission upwards, meaning the noise from footsteps on the floor.)

You can’t lay laminate directly on the screed. It will make a clattering noise as if you’re constantly hitting plastic against concrete! 😱

Next to my workplace there's a hardware store. I went there during my break and asked...

They have a combined product of impact sound insulation and vapor barrier. It comes in an 18 m² (194 sq ft) roll and costs just under 37 euros.

They told me that regular impact sound insulation is not suitable. While you could technically lay the floor without an underlay, the floor would eventually swell.
