The floors on the ground without insulation. It is reasonable?

Greetings to all professional and amateur construction. This article is a continuation of especially my foundation.

I have already said in previous articles, the opinion about the use of geotextiles and gidgoizolyatsii .

It's time for a heater.

I think the soles of insulation slab foundation is a must, but only if, if the plate is used as the radiant floor heating.

But I'm on this type of heating refused. I plan to put in the house brick stove and convectors(As an auxiliary heating).

My plate with ribs, in fact, is on the ground floor.

And for this reason, I have decided that insulate the foundation bottom is not necessary. But honestly, the issue is not closed until the end of. And the reason for that, the next, a huge amount of information and opinions in this regard.

The heat loss.

It would seem logical process when there is no insulation. That is, even if the cooker is not heating source, it is still going through it, the loss of heat into the ground.

But the big question for reflection - the amount of these losses!

Basically, the heat goes out of the house through the roof and walls. But the floor? Can these losses are so small that it makes no sense to worry about?

A clear answer, I have not found.

Soil warms.

There is an opinion that the pillow under the foundation (of course, insulated blind area and the cap) itself is the heat source. Although some heat from the earth? Minimum.

Another thing is that a pillow and a plate can serve as a battery the addition of heat, which goes out of the house through the floor. That during the temporary residence, of course uncertain, but in my case, living in the house all the time, it may well be.

In winter, the heat does not leave much in the summer and cool ground plate refresh the air in the room.

it turns out that the insulation is not necessary ...

Eventually...

• Someone says of calculations and claims the heat will go badly.
• Then the other leads his figures, and he's all right.
• One lives without insulation - cold. another warmly.

Whom to believe?

I decided to go their own, experimentally, by ...

1. Insulate the blind area and the sides of the foundation I am sure. It affects not only heat in the house, but also the safety of the foundation.

2. Insulate the foundation from the bottom, I was not in any way I can, but there is an option to insulate the top plate and only then pour the screed. Although here, too, but there are ...

insulation of 30 or 50 mm special effect will not, and warm to 100 mm, to be honest there is no desire, because of the loss of space, more work and costs.

Therefore, we will check the flooring without insulation.

I plan to put a box with a roof and windows of the autumn and winter to engage in work inside. Therefore, winter 2019- 2020 and will be testing times. Of course the full experiment will not work, but I think the cost of heating, it will be possible to judge what -That.

And I want to hear the opinion of those who have experienced this and knows what to do. Write in the comments... Help very :)
