Hi everyone,
following initial situation: wooden beam ceiling. The compartments of the ceiling were lined with a particle protection and filled with dry fill up to the top edge of the beams, partly above the beams to level the heights. The installation situation was very complicated, with twisted beams, varying distances (sometimes 50 cm, sometimes 60 cm, sometimes something in between), ... so in the end it would have been better if a professional had done it. Or I had simply screwed 22mm OSB to the beams. Well ...
After laying the Rigidur dry screed elements (with 10 mm wood fiber insulation boards on the fill, tongue and groove glued and screwed), it is now noticeable that the screed still springs back a little in some places – estimated about 2mm. Very localized.
Obviously, there is an installation error, or the fill has still found its way into some cracks, or something else.
The best and most sustainable way would be to remove the entire floor and do everything again – I am aware of that.
For various reasons, this is not possible and as mentioned, the floor only springs back "at" two spots locally and to a small extent. Still, this does not let me sleep peacefully and I now want to add another 10mm Rigidur on top – the room heights allow this.
To ensure the highest possible stability, I would now lay the 10mm boards crosswise to the installation direction, glue them locally and connect them with drywall screws to the existing 20mm Rigidur. This would then give me 30 mm dry screed on 10mm wood fiber insulation board, floating installation. Is there anything speaking against this from your point of view? Do you see a better installation option?
