Good evening dear community,

I am currently looking for the most effective insulation solution for my living room. The living room does not have a basement underneath.

The floor structure is as follows:

Foundation → loose fill insulation made of sand and glass (?) → solid wood → parquet on the solid wood, with tiles partially on the solid wood as well.
My current plan is to remove the parquet and tiles and build on top of the solid wood. Are there any effective insulation materials that can specifically help reduce our heating costs and make the floor comfortably warm?

I am quite new to the topic of flooring installation and am looking for the best way to insulate our floor while achieving a nice finish with click vinyl.

I am open to all suggestions.

Thank you in advance, and happy New Year to everyone!

Best regards,
Drakiiii

Do you mean "real wood" beams on which the parquet is firmly nailed? In that case, perlite could be blown into the cavity, or precisely cut foam glass panels could be used. What installation height do you have there?

I am referring to solid wood flooring. No joists in the floor.
The height is not an issue either, since the fill layer underneath is theoretically about 15cm (6 inches) deep. But I would prefer to lay the floor directly on the existing parquet. It seems easier than leveling the entire floor again once everything is removed.

Do you mean there are OSB boards or something similar? Is the parquet floating or glued down?

If you want to insulate starting from this level, your options are limited, unless you are willing to sacrifice about 10 cm (4 inches) of ceiling height. How much space is left above?

I haven’t opened up the floor yet. I suspect it’s glued down. It’s not a floating floor.
A ceiling height of 10cm (5 inches) sounds fine. The ceiling will also be dropped and insulated with loose-fill insulation.
The question is whether the parquet floor alone provides enough insulation since it’s installed throughout the entire room. Maybe just add a cork layer on top and then the vinyl?

If the panels are glued, they will come up along with the tiles and parquet when removed; there is no other way.

If the build-up height and insulation don’t matter to you and you want a quick and cheap solution, you can simply put 3 mm (1/8 inch) impact sound insulation over the parquet, add some leveling compound over the tiles, and then install the vinyl flooring.

Otherwise, remove everything except for the loose fill insulation, and instead of wood panels, lay 6 to 10 cm (2 1/2 to 4 inches) thick XPS or foam glass boards with tongue and groove joints, place thin impact sound insulation on top, and then install the vinyl. With this method, you could even install underfloor heating, as there are very thin systems available.

It ultimately depends on what you consider “sufficient” insulation and how much room height you want or can afford to keep. Decide on that first.
