As the Finns make warm floor in their homes: without pipes and electromates.

I will make a reservation immediately, a strict construction program led by the Terrible Joulupuk, my home would have rejected without looking. The thing is that more than 70 years 99.99% of Finnish houses do not use lagham floors at all. Everywhere, where only you can finish make a warmed tape with the floors on the soil. And I, I believe that this is the most economical and warm form of the foundation. It will not be killed with neither a warmed Swedish cooker, nor a warm basement floor in Canada.

So, as I did in my house, the Finns are made only in hard-to-reach and remote places, where you do not drive heavy equipment and it is impossible to work with concrete. My house is in the suburbs, and if the Finns saw him, the only verdict, which they carried out something like this:

House for demolition.

The whole thing in the complex of inferiority. When four-story monsters are around, and you build one-story kerchief, you will always earn a bunch of complexes. Therefore, it was decided to abandon the low plate and raise the house with a high ribbon at least 120 cm.

Of course, it didn’t help it right so much, my roof is looking at the neighboring houses in the navel, but it created a bunch of problems. And the most important problem is how to ensure a warm floor in the house, which raises from the ground more than a meter and the wind walks under the floor. I don’t even close the LAZ in the base for the winter — it will simply push the plywood.

Electric warm floors did not want at all — why is extra kilowatts to wind. Pulling the pipes inside the tree — pah, ugh, ugh. The slightest leakage and have to open all the floors immediately otherwise the house rotes «on the root.»

What to do?

The only option is to insulate on the old Finnish system, which operated until 1962.

And, you know, it was a solution in the correctness of which I am convinced every time our domestic Santa Claus knocks the staff on a street thermal man and he falls in shock to -30 and even lower. Even a vulnerable, technical, the Altai door does not cope with such a crumble — freezes. And in the house, at least henna, we walk barefoot on the linoleum (our slippers are not in honor, and there are no big numbers in them).

Look in the photo below, how do you have such insulation?

Completely agree with you — quite traditional insulation of gender in lags. And … completely wrong.

How do you traditionally insulate the floor of the lags in Russia?

Everything is simple: from the bottom of the windproof by lags, between the Lag 150-200 roll insulation, on top of a vapor barrier or refoil from the foil, the bar of the draft floor and then goes the purple floor.

Really just … and cold. Such a floor will be bludging, it’s bad to keep warm, so electric or tubular warm floor is required. Otherwise, walk on this house (and sleep too) will have only in the boots.


We go from top to bottom:


Bar 50mm (Finns have all the plane tree, therefore, in fact, not 50, and 48 mm) between which the thermal insulation is crossed

Further lags with a thickness of 200 mm, between which 2 layers of the insulation of 100 mm were laid


In my house, everything is the same, only on top of not plywood, but a draft floor for which LDSP sheets are laid. This allows you to be a little ventilated «rough» space, and more importantly.

That is, the floors are insulated by 250 mm. Stone wool and then such a thickness was recognized as the standard minimum permissible. The developers were recommended to do 300.

But the most important difference in insulation there and we are not in the thickness or number of layers, but in the insulation itself. The fact is that we have in the floors, as a rule, lay the rolled insulation with a density of 12-25 kg / m3.

Finns very rarely use a rolled insulation. Even in the floors, where the Ministry of Service does not carry the load, they laid the slate «parks».

But this is not the most important thing.

In order for the floor to be really warm, and on the floor it was possible to walk like this:

First of all, the density is important:

What does it give?

First, it is not blocked at all, from the word … just not blown away;

Secondly, it is easier mounted, the mat is put in space and is well adjacent to the lag;

Thirdly, the minvatu of such a density is much worse than the mouse. If the Minvata is a density of 10-35 for them — the house is native and one mouse in the overlap can even build a mink, but a new branch of the Moscow Metro, then when meeting with a minor density of 110, the mice spits and leave from such a house away, and put on the entrance Announcement for his: «Host home — Jadde».

Many will smile and say:

It’s expensive, and from where the mice take the overlap, which is closed on all sides plywood!

Yes, expensive! Want warm floor, it is impossible to save. Good insulation is an investment in a gasket for gas.

Well, and what can one of the only mihang … about this in the next article. I will show a specific example to which the sad result was only one of the only sulfur mouse.

So, all the heat!
