This chair is sitting on them...
Safety of furniture is determined not only by fortress screwed the legs. Furniture may not be burnt with fire, since soaked corresponding structure.
But this is not the only criterion of its harmlessness.
In most furniture stores just make round eyes, when you talk about the safety of the proposed product: very rare buyer interested in this issue, because usually selected by their appearance and value.
When buying decorative tile, linoleum, carpets, carpets are advised to consult their documentation on their manufacture, in order to ensure that their composition corresponds to the state standard. Kitchen furniture with decoration of plastic you can almost not be afraid: the kitchen is a place that is constantly ventilated.
Of particular danger is the furniture, which today is mostly made from chipboard. So the output seems to be only one: to buy furniture from a natural tree.
Worst friends - polymers
"Breathe fresh air" means to go outside, even if this street in the city. Because we breathe air, where toxic chemical substances at best one and a half times (often ten times) more than the outside. Our main enemy - chipboard furniture - regularly sends into our lungs formaldehyde, ammonia, phenol, and veneer practically does not reduce the release of harmful substances.
Poisonous vapours washing powders, paints, varnishes and shampoos - their presence, usually unnoticed, and this invisibility prevents us to see the connection between air quality and the quality of our health.
Do not use, for example, polyvinylchloride (PVC) film and isocaptivity when finishing a kitchen or bathroom, for they strenuously poison just in a warm and humid room.
For the kitchen we recommend washable Wallpaper on a paper basis. And if plastered normal - not covered them with varnish. It is practical and, perhaps beautiful, but synthetic solvents xylene and toluene in nail Polish evaporate from the heat and straight into the lungs, and the food of the host.
Not alleivate waterproof Wallpaper ceilings, better Belite - whitewashing breathes, absorbs moisture.
Save from the noise!
Experts believe that if the average intensity level of noise during the day below 50 decibels (DBA), and at night it is below 40, the apartment is quiet. For comparison, the noise of the tram at a distance of 7, 5 m - 83 DBA.
The heat sinks are only three classes:
porous is a plate or felt (glass, mineral and organic fibers, foams with open porosity;
resonance is reminiscent of a closed box with a hole in the middle;
panel absorbers are arranged so that between the wall or floor and a flexible or elastic, but with pimples, screen formed an air chamber. They dampen the sound.
Since noise is one of the main enemies of humans, the scientists a lot about him found. For example, the noise level depends on the reverberation time, i.e. the sound of the reflected signal. And, say, a 30-metre empty hall reverb will be 5-8 seconds. But if the walls and floor with good material, the sound goes out for a second.
Want three times to reduce the noise from the street or neighbors? Cover of "noisy" wall plates of mineral wool. First, it is heat-resistant. Secondly, this is an excellent insulator because wool density is low. And third, hygienists found that cotton is environmentally acceptable.
Don't like wool - lay carpets. No carpets so the linoleum. But rather than the conventional heat-resistant linoleum. Created by new technology, chetyrehmillimetrovyh, porous sound-absorbing base. Soundproofing almost like a carpet.
The wind howled...
In the low house air enters the room through the window and escapes through the ventilation shafts. In buildings it is pulling out through the spiral stair, which is already in the ten-storey house is a kind of samovar pipe with a powerful thrust. The role of the blower play flats on the lower neighbors, from which heat power is sucked out through all the cracks in the stairwell. Up through the pipe, this product BU pressed and pressed with a force in the flats on the top floors. The upper warmer, but they breathe partly aromas of neighborhood cuisine.
To cope with the "samovar thrust" is not yet possible. For the hot southern regions experts have come up with the design of the ventilation shaft of the new type. It is divided into channels, which make the flow of air from flat to impossible.
Those who are doomed to live without this technological improvements, the researchers recommend: first, to seal the door (even better is to make two sealed doors), and secondly, to create intra ventilation (air conditioning activates the flow of clean air, and the fans on the hood - release through ventilation ducts).
Metalloplastic against electromagnetic waves
Electromagnetic pollution has now become a serious environmental problem. Those, for example, who live near power lines or radar, three times the incidence of cancer, frequent functional disorders of the nervous, endocrine, and cardiovascular systems.
The solution? To make PVC curtains, hung them on the window. Not only that, the curtains will reflect electromagnetic radiation from the street, so even in summer, the room will be cooler and warmer in winter.
The fabric to make simply by electroplating on a polymer base is precipitated by several thin layers of different metals. The coating of the metal mesh can reduce the harmful radiation from household appliances to zero.
