Soil isolation, useful or not?

[kae]

Hello,

The house does not have much inertia (hollow brick and concrete blocks), the ground floor is not isolated from the ground. It looks like the slab is directly laid (no crawl space).

It would be useful to insulate the entire ground floor for the comfort of our little feet, but what about the loss of inertia? What would you do ?

There is also the question of summer, would not floor insulation overheat the interior (house in the south) without letting the calories be stored in the slab to empty at night?

Thanks in advance.

Hello,

If I understand correctly, you want to take advantage of the inertia of your slab so that in summer it accumulates the heat of the day and gives it back to you at night. It's practical indeed like that your house stays warm all summer long
personally, yes I will insulate the ground.

Good evening,

yes for the insulation of the ground, and against the heat of the summer of the shutters;).
In terms of inertia, your walls stock more a priorie than your screed and / or slab, unless you have a large glazed area that lets in the sun in winter but not in summer (bioclimatic principle),

The question is in fact rather vague at the end of the day, in order to have precise answers.

Orientation of the house, insulation of the house (if it is just cinder block with a brick counter partition and nothing in the middle, you will benefit from insulating from the outside, because it is your brick and your cinder block that will do the job. storage mass, longer heated but much more inertia).

Otherwise for the winter you can also make at low cost a stone-based accumulator and a glass bottle filled with oil or water, all placed in front of a bay which is in the sun during the winter). an example there are many other solutions.

see you
