How should the platon mat be installed?

[allemannen]

Hi, I am in the process of tearing down a wall at home and I see that our Platon mat seems to go up onto an interior wall. Is it reasonable to build this way?

The house is with a slab on grade from the 80s.

See image against the interior wall towards the bathroom. From what I can see, there's no mat on the other side of the wall. But haven't broken so much.



This is how it looks against the exterior wall.


Right wrong?

Haven't noticed any problem, but it's interesting to know how it is intended if you want to change or rebuild correctly.

You have ventilated floor moldings, right?
It seems well-built as there appears to be a plastic film between the Platon mat and the wall so that no organic material is exposed to high humidity.
Lessons were learned from the catastrophic constructions of the 70s with slab-on-grade and over-insulated floors.
It looks like one of the measures we suggested for mold-damaged houses when I worked with this in the early 80s.
Concrete, Platon, Styrofoam, and particle board on top. Platon raised to ensure air gap, plastic against all organic material, and ventilated floor moldings.
So it seems to be exemplary executed, from what I can see in the photos.

I assume you have had ventilated floorboards?
It seems to be built correctly as there appears to be a plastic foil between the Platon mat and the wall so that no organic material is exposed to high humidity.
Lessons were learned after the disastrous constructions of the 1970s with slab-on-grade and over-insulated floors.

Concrete, Platon polystyrene and chipboard on top. Platon folded up to ensure an air gap, plastic against all organic material and ventilated floorboards.
So it seems exemplary executed, from what I can see from the pictures.

Thank you for your reply!

A question, if I move the partition wall, should I go down all the way to the slab to move the Platon mat in the same way?

It feels quite cumbersome to have to tear up the floor and the insulation in the floor to change a partition wall, but maybe that's what you have to do?

Thank you for your response!

One question, if I move the inner wall, should I go all the way down to the slab to relocate the platonmat in the same way?

It feels quite cumbersome to have to break up the floor and the insulation in the floor to change an inner wall, but maybe that's the way it has to be?

Yes, you have to do this to not destroy the functionality of the floor. The wall stud stands on the concrete, probably on plastic and plastic wedges. This won't damage your fine floor construction, and install ventilated baseboards when you put in the new one. That is, restore it the same way it was built. And above all, make sure to vacuum thoroughly on the concrete slab, so no sawdust remains after your construction, before assembling the floor.
