A "breathing" frame house

[buldozer]

1. The working area is regulated by GN 2.2.5.1313-03 "Maximum permissible concentration (MPC) of pollutants in the air of working zone".
2. Factor of 0.8 for maximum permissible concentration is used in places where there are resorts on the territories of sanatoriums, resorts and recreation areas, cities with a population of more than 200 thousand people.
PS: I was a little bit mistaken in my previous post not in the towns with a population over 200 thousand people but in the recreation areas of the cities with a population of more than 200 thousand.

Here what I found in our Internet, it's about OSB, but it does not matter, the main thing are the numbers.
"In accordance with the state standard 10632-89, the maximum permissible concentration (MPC) of formaldehyde for the air is 0.035 mg / cu m, the air of working zone is 0.5 mg / cu m. Due to the modern technologies of manufacturing particleboard, a formaldehyde concentration in some products was reduced to 0.02 mg / cu m. And this despite the fact that in an array of many types of wood (without adhesive resins) a conventional natural formaldehyde content reaches 12 mg.. A chipboard with a E1 formaldehyde emission index is more environmentally friendly, but with the DSP E2 may not be used in the manufacture of children's furniture. The most environmentally friendly are the Austrian and the German particleboard origin."
i.e the atmospheric maximum permissible concentration is stricter than the maximum permissible concentration in the premises.
The emission of formaldehyde from wood fits into the same class E1, and sometimes exceeds it. But the primary sources are:
Certificate of the European CAP says that the emission of formaldehyde does not exceed 8 mg.
Certificate for the North American OSB said that the formaldehyde emissions are significantly lower than the European standard E1. The figures also exist, but there is a method of measurement and other units.
Document "Negligible or Non-existent Formaldehyde Emissions from OSB (TB102)".

1. Absolutely right, a person has been in a work zone for 8 hours, and in the ambient are he can be 24 hours!.
2. The high content of resins is in conifers. Do you know what is the difference between our plates from imported?. They have in a plate 80% of coniferous raw materials, but in our - 20%, i.e. They use raw materials with a high content of resins
3. And more environmental friendly E0 - I wrote about it (and even I noticed a manufacturer)!.
4. See paragraph 1
5. Where is a sanitary-epidemiological conclusion on the possible use of the premises? A link please!.

[baltazar]

My colleague, thank you for finding!).
About the European standard EN 13986 I have also read somewhere that it is actually much less than 8 mg. And in a sanitary certificate in which local officials on the Canadian / the American plate offer to customers (with all our skeptical view of these pieces of paper) is written-after all, among other things, the "application" - "facing the premises (internal and external)".
I was interested in the local prices of plywood with a class E1 – it is a space!. Twice as different from the usual 2 - 3 grade. About the FC I did not recognize, I will not lie).

1. "... The issue of formaldehydeof plywood SyPly ™ is below the most stringent international requirements: the perforation method (EN 120 and GOST27678), it is about 1.6 (normal - 8) mg/100 g., And on the gas analytical method (EN 717 2) - about 0.3 (normal 3.5) mg / (m * h). Thus, the actual emission of formaldehyde in plywood SyPly ™ 5 (a performatorny method) and (for a gas analytical method) 12 times lower than the European requirements ... " – A handbook of plywood SyPly.
2. And you can see the copies of these "miracle" certificate – a front and a back side?.

Dear, bill ... this given maximum permissible concentration of formaldehyde in the atmosphere – is the maximum. The average daily maintenance of the same order is magnitude smaller. In the living rooms the maximum permissible concentration of CH2O = 10 ug/m3. In Europe, the requirements are less stringent.
Emissions Standard Maximum Emission Level (ppm) - FORMALDEHYDE
European E1 0.14
Japanese F *** 0.09 *
Japanese F **** 0.05 *
Composite Panel
Association (CPA) EPP
0.20
CARB Phase I (2009) 0.18 (Particleboard)
0.21 (Medium Density Fiberboard)
CARB Phase II (2011) 0.09 (Particleboard)
0.11 (Medium Density Fiberboard)
But we must look MVI.

Thanks for the numbers! And I do not know where to hang the American one. For OSB - from 0.01 to 0.04 ppm. This is from the above source.
And what kind of plywood SyPly ™? shortly as possible?.. What is glued? A scope? And then as we all read too much.
P.S. I am not against the plywood, either. And its very actively used. But I am for a fair and objective information about the OSB.

[expert]

SyPly ™ - Syktyvkar Plywood – A brand of Syktyvkar plywood, recorded March 24, 2005 in Russia. They produce a virtually complete range. On page 48 of issue of this Handbook.
Their website has a number of useful booklets.

Actually, I have not understood it!. The North American OSB mainly of deciduous trees. A plywood as they have, and we have is a softwood, is deciduous (a birch). A natural, not only in formaldehyde resins in the wood. The highest content of natural phenols and formaldehyde is in a birch tar. And what you do not like pine tar? The smell of a pine forest is very personal. The OSB with that class of emission is also produced. I mentioned two of these firms - Egger and Kronopol. Only there are other glues and I do not know their field of application.

Alternatively, you can suggest the following structure (the order from the inside - out):
1. A wooden paneling finishing (a birch, an alder, a spruce, an aspen, a pine – species, this list of my personal preference), 30-40 mm.
2/3. The wooden frame (a spruce, a pine) with a filling of soft fiberboard, a SOFTBOARD, 100 mm,
4. The outer contour of a frame of soft fiberboard, a SOFTBOARD, 20 mm,
5. Wooden paneling rough (aspen, alder), 16-20 mm.
6. A bar, 30-40 mm.
7. A hinged front (eg, simulation of aspen timber boards) 20-30 mm.
But.. I am not sure that the instigator of that subject is viewing it.

1 - I agree (but I would have added a plywood with a paragraph number 3), 2 – I agree (on the assumption of a seasonal residence, but it is better 150), 3 - I agree (Is it possible to replace by an ecowool, which is better -? A wool should be cheaper), 4 – I agree, 5 - unless there is a serious danger, "a vandalism"), 6 and 7 - I agree.
It is ideal for fans of the "wooden house" style. The only SOFTBOARD is in the frame (100 mm) should be replaced be the ecowool. It is cheaper and, at least, it is not worse. The ecowool should be insulated inside by the kraft paper. If you still use a SOFTBOARD, I would have also closed the kraft paper. All the same, it is a very dusty thing.

[Summer]

About 2.5-3 times more expensive (with a work) than an ecowool. As for the heat capacity of construction ...it is rather in izba.su, they love to raise such issues.
IMHO, at a very low thermal conductivity of each layer in the frame, the total heat capacity of wall should interest very little.

[baltazar]

I looked at the website of your provider Sanitary-Epidemiological Conclusion and I compared with the conclusion of Cherepovets wool, why there is a such difference in content of formaldehyde - 10 times?.
Tests are carried out by standard techniques, and you can understand the difference of 2-3 times but the difference raise some questions. Most manufacturers use an identical equipment. Other raw materials?.
Other manufacturers list of controlled performance is larger.

With a formaldehyde it can be very simple.
1. I didn’t take into account the background content.
This happens all the time.
2. Gnarled hands of a lab.
3. At present, several methods for a formaldehyde were registered in a registry. Some people use a chromatographic method of analysis. Here, everything is fair – a formaldehyde is separated from an acetone and other ketones and aldehydes.
And methods are based on a photometry. In this method, an acetone and a formaldehyde and other aldehydes and ketones can give an analytical signal. This leads to a significant overestimation of formaldehyde.
For fun, we dripped a few drops of acetone in a probe and then we got 10 maximum permissible concentration of formaldehyde.
a maximum permissible concentration (CH2O) = 0.003 mg/m3
maximum permissible concentration (S3N6O) = 0.1 mg/m3 of air.

[expert]

1. I'd like to hear the answer to an earlier question, "Why does a Donskay ecowool has quantitative estimates only for two substances, and other manufacturers have significantly a higher amount of research?".
2. In conclusion, it is indicated:
"... An application: In accordance with the specifications necessary conditions for use, storage, transportation and security measures in accordance with the manufacturer's recommendations ..." - Where you can see these specifications and the official recommendations of manufacturer?.
At the manufacturer's website and a company do not have these documents. A simple question, I’ am interested in a vendor selection. The main criterion is the environmentally friendly material

[Summer]

I think it is a very useful information!

I think you can get more information about the products from the manufacturer. There are addresses and phone numbers for communication on the manufacturer's web site of ecovata. I definitely have certifications and specifications for their products, but I can’t share with them.
We started our own production, a certification process is underway, it is a protracted process. (I will not tell me that it can be speed up by your known methods, but we don’t do that). As the value of 0.003 mg/m3 of formaldehyde it is closer to the truth, IMHO. But products from different manufacturers in terms of emissions of aldehydes, formaldegides, acetone and etc. should be similar, because the production technology is simple, and to spoil the figure you can only by a directed sabotage.
You can look for the differences and manufacturers of ecowool at other characteristics. Maybe we will be helpful, if you do have a professional interest in the product.
With regard to the product stewardship, it is nothing to fear. "This insidious boric acid" is very dangerous only in making it with a horse dosage over time. Being in a heater, separated from the indoor air, even a simple construction paper, an ecowool poses no health threat. If you do not trust the certificates of the Russian Federation, contact foreign counterparts, the ecowool has a level of M1 for the building materials used indoors. (products within classification).
To close the question, we are currently developing a product), low-borate, 2) without a boric acid, 3) from the primary paper / a wood raw material (there are still people have questions about zinc / lead.

1. i.e the instructions for use and specifications for the Donetskay ecowool are "secret". And I thought so, no wonder they have a certificate of conformity obtained for products made by different specifications.
2. It is only "roughly" because all manufacturers use different raw materials by composition and a quality.
3. It depends on the raw materials and additives - if we want to have a "breathing" framework rather than an isolating film.
4. I trust their ecowool, but I want to find a substitute for a quality home!. When will be (approximately) completed a certification of your products and when do you plan to begin a mass production?.

[constructor]

Do not look for a black cat in a dark room where there it isn't. The change was occurred due to the obsolescence of previous (1997 year it seems) – the osprey was considered as a raw material (the line was bought as a supplement to one of the PPM), the circumstances have changed, but the products were produced under the old specifications, which were recently upgraded and it is nothing terrible. no one says about specification in free access, in any case, I did not notice this the overwhelming majority of producers.
2. So, you are right but it is not so. It is not affected on emissions of hazardous substances. What's wrong with what we do not add cardboard in our products, and "..." allows up to 30%?. The only difference is a quality. The requirements will not be infringed.
3: No. All manufacturers of ecowool in Russia make it out of recycled newspaper (maybe the addition of other varieties), and borates. What other supplements can there?.
4: It is possible to book now, hopefully, we will complete the certification on February.
