Soon we'll be installing laminate or hardwood flooring in the children's rooms and in the parent's area. Until now, we have always laid 5 mm thick impact soundproofing or glued parquet over the entire surface. However, now we have underfloor heating and the floor construction has to allow the heat to pass through as well as possible.
Is there a certain type of impact sound insulation that will work for this, and how thick should it be? Have you had any positive experiences with certain products?
