Why a wooden house is not environmentally friendly, and walls should not breathe

Often in the comments they write about the environmental friendliness of the house. That wood is a natural and most environmentally friendly material. And concrete is chemistry. I will ask such sofa experts: What will you cover the floors with inside a wooden house? If with varnish, then your house turns into a gas chamber, although then you will not even feel the smell. Laminate, linoleum, carpet - these are all materials that also emit different chemistry. Very rarely, a wooden house is built on a slab foundation (they believe that this is an overpayment) with a porcelain stoneware finish.

Now the trend is screw piles for frame frames and wooden houses. With floors on logs (beams). Few people make the topcoat on such a foundation in the form of a monolithic concrete screed and tiles.

At one time, I covered the floors in the relaxation room in the bath with wear-resistant yacht varnish from the economy segment. So after 8 years, when you open the front door in the summer, you can smell this varnish. There is no environmental friendliness.

Also, if you have built a house from profiled timber, rounded, planed or round timber - inside you need to cover the tree with impregnation (glaze). Otherwise, it will darken over time. Acrylic impregnation is one thing. And if alkyd - the background will always be. Although you may not feel it.

And if you do not cover the inside of the log house with impregnation (its function is not only decorative, but also to protect the tree from UV and mold), then in the bathroom there may be such a picture. Mold is also not visible (wood is a breeding ground for fungi - and is it environmentally friendly?

The smell of wood. Pleasant aroma. But what is released from the resins and how will this affect allergy sufferers, asthmatics for several years of living in such a house? Where are the statistics? Who was collecting the information?

In a stone house on a slab foundation, it is optimal to make warm floors. And on top of the screed or directly on the USHP - only tiles. Chemistry does not stand out from it. What can stand out from ceramics and granite chips? Radiation - someone will say. Well, measure it. Dosimeters are now at an affordable price.

Dust in a house made of round timber and rounded timber accumulates on bends. The walls in such a house are like a dust collector. And where there is dust, microparasites start there. Is it also environmentally friendly? Moreover, the hostess of the house is ready to clean this dust on the walls at least once every three months?

Second myth: the walls of a house must breathe

Allegedly, they really breathe - only wooden walls. And competent builders say simply: ventilation in the house should breathe, not walls. Walls should be heat-efficient. And I agree with this opinion.

Wall breathing is the absorption of moisture into its structure. It doesn't do anything good. At the dew point inside the wall (or in the insulation), moisture condenses, and mold forms on the surface. And the material itself loses its thermal characteristics due to moisture. A wet minelab is no longer a heater.

Even if the walls “breathe”, but there is no ventilation, then the level of CO2 rises very quickly inside, especially when many residents live.

So a well-functioning ventilation is needed in the house. Someone does not even save on ventilation with good recuperation (saves heat at home) and with intake, filtration and heating of outside air (with automation, control of CO2 sensors). This is a different, modern level of approach to the topic of environmental friendliness inside the house.
