LECA with insulation

[Hålta]

Is it possible to glue EPS panels directly onto a LECA wall and achieve both airtightness and good insulation without using other fasteners like screws, etc? What adhesive can be used? Preferably, I want to achieve airtight joints at the same time...

considering 200 mm 100+100mm or how should it be done and what quality is needed?

If I need the same insulating ability with other material, how thick insulation do I need then?

Would not choose to just glue, use some screws as well. Tongue-and-groove boards might work.

Eps insulates approximately like regular insulation, about 0.035

Pl700. Nail the boards with 3" nails until the glue has set. Best regards, Palm

Isn't EPS more stable and free from mold and moisture problems?
I also want to make the wall airtight, even at the glued butt joints, which is why I'm looking for a method that both attaches the EPS and seals the wall in one step.

Thank you
What do you think about the density? Will I get better density with this glue and who sells it?

Perhaps obvious, but have you considered EPS (foam plastic?) fire properties?
