ᐅ Installing Underfloor Heating Beneath Laminate Flooring

We are currently in the process of buying a house. It is 20 years old (Hanlo timber frame construction) and naturally shows some signs of wear. My wife is a big fan of underfloor heating and definitely wants to have it again, especially in the living room. During the viewing, the previous owner (unfortunately not very knowledgeable about building technology) mentioned that there is an electric underfloor heating system installed beneath the tiles in the living room, which are partly cracked.

Now, we want to remove these tiles because they feel cold and are not particularly attractive, and instead install laminate flooring. I already know that the laminate cannot be installed as a floating floor but must be glued down due to the thermal bridge. Is any standard laminate suitable for this purpose? What type of adhesive should we use, and what else should we consider?

Do you want to glue it down because an electric underfloor heating system is installed? I would not recommend gluing laminate flooring. It is usually not designed for that.

Well, the heat is supposed to reach the laminate surface somehow. If I have the impact sound insulation layer in between, doesn't that act like insulation and the foundation gets heated instead? 🤨

We also installed our parquet flooring as a floating floor. There is special impact sound insulation that is suitable for underfloor heating. The same applies to laminate flooring. Generally, laminate is suitable for underfloor heating.
With parquet, I know it can also be glued down. Laminate is usually always installed as a floating floor.
I believe the heat loss is not significant enough to be noticeable.

Since the expertise in our local building supply store is... well... 🙄
Is such impact sound insulation commonly available, or is there a specialized retailer for this type of building material?

Why install impact sound insulation when there is only the foundation beneath?
