A "breathing" frame house

[constructor]

A vapor burns, but it is sandwiched between a drywall and an ecowool, first, the drywall should burn (what kind of plaster do you recommend, and how many layers?)
A fiberboard is not so environmentally friendly? A windscreen, too, must be thrust under the slab material, so as not to burn or not? What a smart vapor barrier do you recommend, a brand or a price, please? And if you take a sheathing on a top of5-cm slab basalt slam, to increase the fire safety? With regard to a ventilation, it seems to me you do not understand me at all, but I'm not going to prove it to you. I'm just telling you, I know it inside and out, and when I blogged about a device and a volume of air in the reality ... And I know who is and where. A concretization is needed, not less than the construction of walls. And finally, there is a speed control, as well as I wanted to set up.

How do you express the concept of "environmentally friendly"?
As for me a basalt wool is eco-friendly. And someone said that this a terrible poison which causes all the evils on the earth. Again, we need to talk not just about the material but about the material of a specific manufacturer. A bologna of one manufacturer can be very tasty, but from the second it can be so disgusting by taste and can also cause poisoning. But I do not understand you. Are you a fitter of ventilation systems? Because you judge all by your experience and personal knowledge and you don’t like all calculations and theories about which you are spoke, and which, in principle, made by the designers of ventilation systems.

Think about it from the other side. What are the main causes of fire in a private home?
1) A poor electrical
2) Chimneys and furnaces
3) An arson or an external factor.
The first 2 - their decision is up to you.

About the fiberboard, I didn’t understand. About the windscreen is clear, thank you, about the fact that it burns, at least will not create such a critical temperature of combustion as a wood.As for the ventilation, of course, it’s OK, but the calculations are based on CO2 only seem to me not quite correct. But scientists believe I don’t prevent anyone from believing. They will tell you a lot of things, about a global warming or a AIDS... But the answer is "I suspect that in your steppes in general it would be difficult to find something "smart " ...Think about it at leisure, is it worthy of a wise man.
It's like how Americans think that there are bears everywhere in Russia, although there are rumors that go just in Moscow.
I wrote about a job profile and a ventilation.

So, it is still possible to let a home steam into the wall? It is also a progress. And what kind of a heater these experiments are carried out? It's very important, because of the vulnerability of insulation from the consequences of finding in it a dew point, such necessary measure applies, as a vapor barrier. You can look at the link to see. But besides a mineral wool there are other effective insulation materials that do not deteriorate from a moisture, but do not lose its insulating properties and are easy to dry out. For example, an ecowool, a mettemplast. The Finnish Ekorex just uses this property of ecowool and manufactured by this technology products are sold in 16 countries, despite the fact that because of the use of laminated veneer lumber in it, it is not quite cheap.

And the fact that the ecowool less afraid of waterlogging, this is probably a fact. But perhaps, this fact it is better not to overdo it.
"So, there is nothing, and "smart" membranes, which are rare in Moscow and Petersburg, are sold in every corner or a household, according to you? I'm just trying to figure out this question. A vapor barrier is used because we are dealing with a layered wall, where each layer has its own characteristics. If you follow the condition, which someone said (each layer has to come with an increase of a water vapor) and you can install a vapor barrier without a mineral wool, if there is layer after it with a high water vapor.

[bill]

You described the case of a steam "locking", the ecowool is nothing in this case. In a homogeneous wall, the material which is much more resistant to moisture than a wool, works well and without complying with the rules "from the lower to the higher water vapor permeability". The mineral wool itself created that rule.

[buldozer]

What are you thinking about a plasterboard? From all the information above, perhaps it can be concluded, a "breathable" house can be obtained and its "breathing" will be expressed in a low vapor permeability, and it will give a little more balanced system, compared with a total isolation. There is no particular influence on a climate. Is it?

[Summer]

If there is not enough ventilation it will not work. If you shut up all cracks and sit there like a marmot it will be, but there you will not think about a humidity. It is purely my opinion, never impose. I will not write in the topic anymore. IMHO everything is said - "He who has ears let him hear". And then again, a metaphysics at the level of sensation begins.

[baltazar]

What kind of fiberboard? Our domestic fiberboard is quite harmless. But judging by the fact that you have not found them very suspect that you have in mind is not fiberboard (with a wooden "wool"), but something cement or something fiber and for some reason is chinese. And the Chinese did not bother with the environment.

[bill]

A fibrocement material unlikely is strong, where was mentioned the fact the people built a house or a facade of some fiber panels, as I understand the top was plastic, and they had a dimension of 3000 * 600, although I will not argue. But in principle, there is also something different than a cement. And the Chiner is closer. It’s fun. But how to order a fiberboard from our west I dod not even know, maybe can someone will tell me

[Summer]

There are many Finnish materials, including almost the "Platform". But I do not tell specifically, you do not have it, and I will not look it up. I even remember an article where this information appears for the first time, once upon a time was a very heated discussion with one man that throw out a bunch of links, including a page on a very clumsy English, where it was written that after numerous experiments with the using the latest HVAC equipment (the Finns) have concluded that such a ratio, helps not to accumulate a moisture in the wall in 5 times. And then that figure has spread to other publications.
