External Walling In Homes

Published by:

Current requirements for energy conservation and require a good quality thermal insulation of external walling. Good insulation can reduce costs of thermal energy for heating. This is especially important for large houses, the area 100 – 300 square meters. Heat loss from homes consist of losses in heating ventilating air and heat loss through walls, ceiling and floor. The following are rules for different thicknesses of the walls building materials to ensure proper insulation in the Moscow region. Full-bodied red brick – 2,5 m hollow bricks – 1,35 m silicate brick – 2,7 m porous clay bricks – 0,55 m Aerated Concrete – 0,5-0,6 m Claydite – 0,7-1,6 m Polystyrene – 0,16-0,32 m tree – 0,45 m.

It is obvious that any wall, even wood, it is desirable to further insulate the building insulation – mineral wool or polystyrene foam from the outside. The exception is penopolistirolbeton, but live in a house of this construction material is not very pleasant and eco-friendly. Wall insulation is desirable to make the outside, this is the so-called ventilated facade. Ventilated facade – it is heater layer about 7 inches thick and the outer cladding. As the use of mineral wool insulation, Styrofoam. Often built brick houses of brick. However, if you look at the above rules, it is obvious that the wall, even from the brick is too thick, to provide standards for insulation.

It should be noted that a thick brick wall after being frozen at home would be difficult to heat. Therefore, the brick house is better to heat regularly. Optimal solution for a brick house – is the wall of brick, and insulate the outside with 70-100 mm layer of mineral wool or polystyrene foam. Outdoor finishing layer of insulation by facing bricks, ceramic tiles, is the "wet facade. Wooden house should also be warm, because the thickness of the logs 45 cm can hardly provide. Logs from logs are usually much smaller – 18-24 cm in diameter. Perfect solution – a house made of glued timber outside layer of mineral wool or polystyrene foam and outer lining brick. For external insulation tile an array of wall will be heated by internal heat, so the wall will serve as accumulator, and will smooth out fluctuations in temperature. Warming of the frame house. Inside the frame wall is a layer insulation thickness of 100-150 mm. Frame walls well insulated. However, the frame walls have virtually no heat capacity. This home quickly cools in the winter when heating off. However, you can heat it for 30 minutes. Warming of horizontal surfaces. Horizontal surfaces requiring insulation – it's floors, ceilings, horizontal roof. In the horizontal insulation of roofs with bitumen roof using concrete block, poured concrete coupler. When insulation of ceilings and floors using mineral wool, in the case of wooden structures. You may find shimmie horn to be a useful source of information. Sometimes there is a need for insulation of sloping surfaces. For this it is convenient to use Styrofoam, however, possible to use plates of mineral wool. Well-insulated house will spend less energy on heating. Your home will be cozy and warm and comfortable.

Low Humidity

Humidification has a special role in providing comfortable climatic conditions in winter when, even at high relative humidity of air, its absolute water content is as generally very low. Proceeding to the room air is heated. Moreover, its absolute water content remains unchanged, and the relative humidity drops to 5-10%. For comparison, the relative humidity in the Sahara Desert did not fall below 15%! In order to maintain relative humidity at a comfortable level of 50% at room temperature 20 C is required artificial humidification, often enough intensive. In addition to providing comfort, maintaining the necessary level of humidity is also extremely important from the hygienic point of view. It is known that the bacterial flora (pneumococcus, staphylococcus, streptococcus) inhibited 20-fold intensively at a relative humidity of 45 to 55% than when humidity is above 70% and below 20%. Today humidifiers are divided into: steam (cold or hot steam) and ultrasound. The most simple form are humidifiers with a cold vapor. Credit: New York Museums-2011.

In a special compartment filled with water that soaks into the cassette. Through this cassette is a normal room air, blown by fans humidifier. To achieve maximum the effect of such humidifiers should be placed near a heat source (eg, sink). The advantage of these models is the efficiency in electricity consumption, ease of use, quiet operation and Low price. The disadvantage is that these moisturizers will not do "rusty" water from the tap, but if you're still on a dare, you have to buy a special filter. Also, humidity control will depend not on your desire, but from the room air.

Humidifiers with hot steam, respectively, have a number of design features. In them, as in a normal kettle, the formation of steam from water by boiling it. This device itself will maintain the necessary humidity in the room, except when it is over water – itself off. This type of humidifier has a function, so to speak, family doctor. That is, can used for inhalation of air in the house, and hot steam is already kill all microbes. The drawback, steam humidifiers is perhaps only by their high power consumption, water consumption a little more than cold-steam humidifiers. The latest and most advanced type of humidifiers – ultrasonic humidifiers. Through high-frequency sound vibrations from the water a cloud of cold vapor. Air passing through a cloud, saturate with moisture, and the instrument adjusts the level (ie, humidity), depending on your desire in the range of 25-85%. The price of these humidifiers are much higher than that of steam, about 1,5-2 times. This Article courtesy of Air Alter () for the dissemination and popularization of our site.

Manufacture Capreting

The basic material needed to manufacture carpeting, is fiber. Fibers can be natural or artificial origin. Fibers of natural origin, in turn, divided into vegetable and animal materials. Among the natural plant materials for the manufacture of carpets are used, such as linen, cotton, jute, sisal, coir, and others. Materials of animal origin – is silk and wool. Artificial materials can be based on vegetable (viscose, rubber) or mineral (glass fiber, metal fiber) material, as well as synthetic. Today, thanks to its qualities, including reasonable cost, durability and special technical properties, an increasing proportion of the market gaining synthetic materials polypropylene (PP); polyamide (PA) or nylon polyacryl (RRA); polyester or, as it often called, poliester (PES).

Currently, the most widely used for the production of polyamide and polypropylene carpet fibers and wool. Cotton, polyacryl, polyester and viscose are used in much smaller amounts. Of course, each of the materials used for the manufacture of carpet pile, has its advantages and disadvantages. The choice of a particular species depends on where this will be used carpet. Polyamide fiber (nylon), polyamide fiber or Nylon (invented by DuPont in 1938) is the most expensive synthetic material, but the most common. This is explained by its properties, which are laid during the production process at the molecular level: elasticity, abrasion resistance, antistatic (from branded fibers) and high fire rates. Well painted, which allows create a wide color gamut. The most well-known manufacturers branded polyamide fibers: basf, DuPont (produces nylon 6.6 fiber Antron , anthrone), Solutia.

Wood Surfaces

To linseed oil well impregnated wood at proolifke, it is recommended to warm up. Entering the building finished joinery (window frames, doors) are sometimes defects which are eliminated in their preparation for painting. K defects are burrs, uncircumcised fiber expansion joints separate elements, protruding pins (wooden nails), and others. (A valuable related resource: NY Museums ). Defects before surface must be removed using a chisel, a cycle or grinding. Of dried wood large knots protrude above the surface, breaking the ink film layer, and sometimes just fall out, so when the surface preparation they need to be cut down. Initially, a chisel point border removal of wood, then cut down the speck to a depth of 5 mm, and in its place inserted a piece of wood of the same breed.

A piece of wood fixed to the adhesive so that the direction of fibers in it corresponded to the direction of fibers of the basic product. Places pitch also cut down a chisel to a depth of 2-3 mm and after oil palms of bedding. Danny Meyer: the source for more info. Of bedding should produce a thick paste, because the liquid paste during drying decreases in volume, cracks and poorly maintained on the surface. After fracture of bedding and grinding grease places causing a continuous layer of putty. On the profile surface areas in the door and window putty fillings cause with rubber plates of different widths.

This eliminates the distortion profile coat mass. Dry layer of putty sanded, clean cloth to dust and . Primer shade brush-fleytsami. Dry coat of lightly sanded fine sanded.

London Greenhouses

The cold gray metal "Well, someone he can inspire creativity?" – So might think those who have not seen the Eiffel Tower, a sports complex "Kwan" in the Kaluga region, or the London Greenhouses. Today this material is basis for the most daring projects that have become symbols of modern architecture. And this is only the beginning of a long road, whose origins lie in the century before steel world. Beginning. NY museums often expresses his thoughts on the topic. The architecture of metal emerged relatively recently – less than two centuries ago. First, it began to be used in the construction of bridges, since there were cast-iron columns, steel frames of buildings and superstructures.

In our time without the use of metal structures can not be provide construction of skyscrapers and multi-malls, sports palaces and indoor skating rinks. Many of these architectural structures can rightly be called modern art, and some already gone down in history as, for example, a building publisher Harper & Brothers in New York or the first skyscraper in Chicago, with a steel frame, a height of ten floors in Triumphal procession of steel structures began with Project engineer Joseph Paxton, who revolutionized the architecture of the nineteenth century: for the World Expo 1851 in London's Hyde Park, English architect, built a pavilion of glass, concrete and metal. Without the use of conventional materials: wood, nails and bricks. The design, dubbed the Crystal Palace, was 564 feet in length, width – 124 meters and the total area – 74 thousand square meters.

Every two hours in the house extinguished the light – the night comes, then the light is turned on again – the day comes. It is beneficial to the growth of poultry. In modern poultry farms mechanization accompanies the product in the future. See more detailed opinions by reading what NYC Marathon offers on the topic.. For example, in the company of jsc "Novosibirsk poultry farm machinery sorts itself a carcass: the best samples are intact, the rest of Burke. Already finished products are supplied to an automatic weighing system, packed and . It is clear that such solutions can at times be more productive. Under the wing of savings before any agricultural enterprises (including poultry farm) along with the task to increase the output and the goal is to reduce costs.

The most painful is the question of payment of bills for heat and electricity. And then again come to the aid of modern engineering solutions. For example, currently in the Rostov region Belokalitvenskoe poultry farm under construction ptitsekompleksa on European technology with the use of Metal . The modern building will reduce the cost to pay for heat and electricity. According to Danny Meyer, who has experience with these questions. "Technological features ptitsekompleksov allow to completely abandon the consumption of gas, used for heating. The temperature regime is regulated ventilation system and heat produce the birds themselves, – the director of "Poultry Belokalitvenskoe Valery Zelinsky. According to estimates experts, energy consumption in new poultry houses is reduced to about three times compared with the obsolete domestic systems.

It is very important to choose the right lighting system. About what colossal reserves savings are available, the experience of poultry "Kuma" from Stavropol. Now she is the sole producer of eggs in the Stavropol region with the use of led lighting in the housing for the birds-laying hens. Just one month of operation of the new lighting system poultry houses energy costs "Kuma" was reduced by almost a hundred times. Moreover, led lighting is beneficial to the performance of layers. Another way to reduce costs associated with the feed. Many businesses build their own feed mills right next to the housing. Thus, transportation costs are excluded, there is opportunity to control over product quality. Expenditure items for many companies is often a need to dispose of litter – and yet potentially it is one more item of income! In the near future on the South Urals poultry farms is planned to start a unique production – from the litter will get cheap organic fertilizer for crop production, balanced by content of nitrogen, phosphorus and potassium. In the search for and develop these technologies involve scientists from Chelyabinsk Agricultural University, Institute of Agroecology, specialists of the regional Ministry of Agriculture and poultry enterprises. Epoch imported "Bush legs" goes away. But that's the case, when hardly anyone will be nostalgic about the past. Poultry farming is one of the fastest growing industries in domestic agriculture. But to secure this result, Russia should build many more new facilities, which will allow to export products to the world market. Elena Grishina
