Most of the territory of Russia and other countries lies in such a climatic zone that it is necessary to do without heating in houses. And high prices for electricity and gas make you look for ways to save energy.
The easiest method is to warm the facade of your house or apartment. And in this case we need to take an example from Europe and America, which have long been engaged in this. In the developed countries, the effectiveness of insulation of facades of houses and buildings has been economically proved. It remains only to choose the material.
It turns out that there are a lot of heaters, but the best is foam expanded polystyrene, or all the usual polystyrene foam. He on a head surpasses all competitors on the basic parameters, and facade decorative plasters it is possible to use the most different.
Thermal insulation nevertheless remains a fairly new business, which immediately became overgrown with rumors and gossip. And the lack of information on this issue ultimately leads to problems – the technology is violated, the wrong material is chosen. So it is worth debunking the basic myths about the insulation of walls with polystyrene foam.
It is worth choosing the most dense foam, then the house will be warmer.
In this issue it is worth turning to simple physics. With an increase in the density of the material, the molecules will adhere to each other more closely. These particles are better able to transfer heat energy to each other, increasing the thermal conductivity of the material. As a result, it turns out that the cold from the street will quickly penetrate the dwelling. This suggests that it is better to keep the heat just a foam with a lower density, let it and its strength will be less. But in fact, in the presence of a reinforcing and decorative protective layer, this deficiency will not be so important.
Warmer and more reliable will use Styrodore.
If you intend to get involved in a war with neighbors and survive a real siege with throwing stones, then it’s really best to choose extruded polystyrene foam. Let it not keep heat as well as a normal foam, but it is much stronger. It is worth to think about its durability because of the limited useful life of reinforcing and adhesive materials. As a result, in 25 years it may turn out that the facade is naked and saggy styroid.
It will be cheaper to use mineral wool.
By itself, this material is really cheaper than polystyrene. However, in order that in the house it was really warm and cozy to buy not just ordinary mineral wool in rolls, but mineral wool slabs. Here they are more expensive than plates made of expanded polystyrene, besides, they also have disadvantages in comparison with it.
The facade, insulated with polystyrene foam, ceases to “breathe”.
This is not true, because the foam plate itself does not breathe, but the general structure of the facade. This is due to the joints and the upper rib of the air layer between the heater and the wall itself. As a result, this system gives the most optimal air flow for ventilation of the facade, as well as breathing of the walls. The moisture inside will not appear and accumulate.
Warm facade will not give a significant increase in heat in the house.
Although the “warm facade” does not really give rise to heat, it will be able to keep more than 30% of the heat inside the building, which would leave without a heater. So if the facade is not insulated, it turns out that we are partially heating the street for our own funds.
Polyfoam is not an environmentally friendly material.
Foamed polystyrene foam is a homogeneous product of foaming, which does not contain any chemical additives or formative substances. So during the operation this material does not emit radiation or any vapors. It can no doubt be argued that for use, polystyrene is the safest and environmentally friendly thermal insulation material of all that is on the market.
Warming the facade is an expensive and unprofitable occupation.
In fact, supporters of this opinion are somewhat right. The pleasure is really not cheap.But the effect is worth it, because you can immediately and strengthen your walls, insulate housing, decorate the facade. And all this will cost about 2 thousand dollars for a house with an area of 100 squares (this includes materials and work). Is this a large sum? Is it more profitable in the long run to rest a week in a bothersome Turkey or to buy a trendy laptop? But the insulated façade is the basis for comfort and coziness at home, it is a guarantee of the health of the whole family. The very dwelling will receive a European style, for years will become stronger and more reliable. And in a few years the money will return in the form of saved energy resources. After this, you can start counting for invisible earnings, which also debunks this myth.
Decorative plaster in case of polystyrene finishing is not required.
There is an opinion that it will be enough just to paint the heater. Paint can really protect against various kinds of influences – temperature, light, chemistry. However, in any case, protection from this layer will be less than from decorative plaster, which also performs the role of mechanical protection of the reinforcing layer. So when using the “fur coat” and “bark beetle” in the decor, the owner actually doubles the life and service of his facade. And the appearance of the home will undoubtedly improve.
There is no difference in the choice of materials for the insulation of the home.
More often performers do not advertise how they will warm the house. It is necessary to show adherence to principles and control the choice of materials. There are several important details. So, the manufacturer of a mixture for gluing and reinforcing polystyrene foam should be of high quality and at an affordable price. It is necessary to pay attention to the producer of expanded polystyrene. This plant must have a certificate for its products, comply with GOSTs, have the required density, reliability and quality. The reinforcing mesh should also be of high quality. You can not take material from low density, sore, fragile or frankly cheap / Chinese. It is worth paying attention to the quality of the decor, as well as its varieties. It will be better to take domestic finishing materials created using European production technologies. The landlord should ask what kind of decorative plaster is included in the estimate. Mineral will be cheaper, and acrylic – more expensive. True, acrylic will provide a stronger connection between the fine grains of plaster, such plaster will be more uniform with respect to the dry mineral mixture. Also, acrylic will be embellished throughout the entire decor, which will give the color a greater saturation and durability.
There is no difference who will insulate.
An inexperienced specialist can also use glue for tiles, which is clearly cheaper than a special adhesive for thermal insulation. Plates made of expanded polystyrene will stay on the wall for about a couple of months and disappear, since they were held only by mechanical fastening. This can be dowel-umbrellas, perforated corners and plinths. Credulous customers do not go into the process, what unscrupulous performers use and earn good money on this. It is worth knowing that per square meter of foam plastic according to the technology requires 5-6 dowels-umbrellas, and not 2-3 pieces, as some facade make, trying to save. Before applying the adhesive on the surface, it must necessarily be primed, which must necessarily and so enter into the cost of insulation. In the decorative layer must necessarily include primer based on quartz sand. The seasoned and cunning facade, taking into account these nuances, will be able to earn extra money at the expense of the customer. The service life of a poorly made facade will be reduced from 20 years to 2. So there is a difference, which artist to hire – proven or cheap.
