For the temperature of the onset blistering take the temperature at which the already obtained with expanded clay pellets density 0.95 g/cm3. The maximum possible firing temperature is the temperature of the beginning of melting of the surface of granules. To expand the temperature range of swelling using this technique, as raw clay dusting powder granules of refractory clay, which improves firing temperature and avoid melting of the granules. Expanded clay aggregate has the following features: – Easy and high strength – excellent heat and sound insulation – fire resistance, moisture and frost – acid resistance, chemical inertness; – durability – environmentally friendly, Safe, natural material similar to ceramics – a high ratio quality / price. Application of the most widely used claydite finds as a wall material. In some regions of the wall panels keramsit became the basis for industrial-scale construction.
Especially effective but the application for the wall panels are well expanded lung keramzite gravel marks 300, 400, 500 (for bulk density). Density structurally keramsit insulation for single-wall panels, usually of 900-1100 kg/m3, compressive strength – 5-7,5 MPa. Such concrete in construction performs both carrier and heat-insulating function. In a two-or three-layer wall panels required bearing capacity can provide a layer (or two layers) keramsit structural and heat shield – a layer of macroporous insulation keramsit density 500-600 kg/m3.Teploizolyatsionny macroporous claydite – the lightweight concrete, which can be obtained on this filler. Its density at the minimum cement consumption only a little more bulk density keramzite .Na Leca marks 700, 800 receive structural lightweight concrete with a compressive strength of 20, 30 and 40 MPa are used for the production of slabs and coatings, bridge building, where it is particularly important to reduce the weight of structures.

Siding made of other materials Steel siding is commonly used in industrial construction. For rust protection on steel special coating. Siding with a textured surface is produced in the U.S. alone, and with the smooth – in Europe. Material differs rich colors, and coloring, you can choose from a catalog. Unfortunately, the steel has disadvantages – they're heavy and prone to corrosion.
Aluminum siding has all the advantages of this metal – no burns, no rust, is lightweight, durable. The material covered by a pvc film, simulating the tree that protects the surface from scratches or paint, which is cheaper. The surface of the siding is embossed or smooth. The spectrum of colors wider than that of vinyl siding, but less than that of steel. Aluminum siding can withstand shock loads poorly and may be deformed during handling. American Aluminum siding is cheaper than steel. Europe is virtually identical to the latter's tsepe. You may want to visit Oracle to increase your knowledge. Wood siding is made from wood fibers, pressed with different binders under pressure at high temperature.
Does not contain harmful tar. Coating material consists of several layers of protective paint. In the context, he recalled mdf and looks like natural wood. Can be used even for interior decoration premises. However, while the wood siding is not very popular, besides it is quite expensive. According to experts, it is better to use in dry climates, as the material can absorb moisture. In addition, it is combustible. Cement siding – the latest achievement of overseas industry. Made it out of cement with the addition of cellulose fibers. Initially, only the primed surface, and then the siding must be covered with paint. Outside material like a fine painted wooden plaques. Fire-resistant siding, it can be used for decoration of kindergartens, schools, hospitals and other facilities, which imposed stringent requirements for fire safety. In the installation of the necessary caution, since the cutting of siding produced silicon dust. Vinyl lining Immediately it should be noted that this is not siding. Vinyl wall paneling, a panel thickness of 10 mm wire structure used primarily for finishing the interior with high humidity. It is not intended to trim the outside, because the production is used quite a different composition of pvc. The service life of lining shorter than that of the siding as well as the raw material is another. The surface is smooth, without fracture, the relief and the mounting edge. Vinyl lining is cheaper than vinyl siding. Instead of a conclusion in search of the siding at a reasonable price is not should ring up shops. In the best case you can only find out how much the main band. Tempted by its low price, do not forget that we need another set of decorative finishing profiles, with the acquisition of which easily negate the imaginary cheapness of the main bands. Acquire the siding should be in reputable firms, where the drawing of your house for free (!) Will calculate the cost of all materials with regard to accessories.
Weight of the standard package does not exceed 10 kg, so the material can be easily moved around the construction site, raise the roof. Primaplex easily cut with a knife or a saw with fine teeth; * Longevity. The ability of insulation boards Primaplex perform their functions throughout the lifetime of the building (30-50 years), the stability of its characteristics, such as thermal conductivity, compressive strength, low water absorption, and lack of corrosion and resistance to multiple freeze-thaw cycles makes them durable. Traditionally, the plates Primaplex used in the device inversion roofs. Inversion roof structure is used, usually on a concrete base at the organization operated roofing. According to Gary Kelly, who has experience with these questions.
Stringent requirements that apply to insulation of roofs, make extruded polystyrene insulation is practically the only device in the pedestrian terraces, roofs with landscaping, parking. One option use of the material Primaplex – inversion of the roof where insulation board stacked on top of which was built earlier classical roofs in order to improve overall insulation characteristics of the structure. At the same plate Primaplex laid directly over the old roof without removing sealing or repairing ties. Surface insulation layer of geotextile is laid over the gravel ballast. Plate Primaplex used in standard classical designs. Experts have already assessed the merits of using plates Primaplex on roofs with a base of steel trapezoidal sheet. Greater strength at the strain, low thermal conductivity, ease of delivery of the material on roof, easy installation, can be assembled at any time of year – all this speaks in favor of using extruded polystyrene in classic designs with synthetic membranes.
Distinguish one breed from another can be in sections, which are represented on the samples in the office of any self-respecting company. Windows. Basically, now used triple-pane windows. Glazed windows is a completely sealed structure, consisting of three windows (triple-pane windows), installed parallel to each other. The space between the windows is filled with special gas, on the perimeter glazing installed Desiccant material. In other words, the glass – it is definitely a complete system that dramatically improves sound and thermal insulation properties of wood windows. External glass can be replaced with shock-resistant, bulletproof, tinted, patterned, but it therefore requires additional cash investments. Paint.
This is one of the most important, perhaps, of differences. Today Paint is perfect, there are different shades and tones. They not only protect the frame from rotting and damp, but also allow her to breathe. At the same time are totally environmentally friendly materials. Dyes come in and under the nail that serves to emphasize the tree structure and make the window is really an aesthetic appearance.
Fittings. Almost too perfect. Mostly on modern windows put the German or Austrian fittings known manufacturers. Naturally, the need to choose wooden windows with adjustable hinges. These are the basic differences between wood windows are available in the present. Yes, of course, modern wooden box all is well. But to purchase is not overshadowed by your mood, you need to choose a wooden box. In what lies the difficulty? Here are a few criteria, which should look for when buying windows: Professionalism personnel office or store, which sold the product, the quality of the samples of windows and related components (castings, mosquito nets, window sills), Period of construction, cost. Quality. The quality of one or different window designs can be judged only by its appearance. It's simple, either you like the window or not. If you notice dissolves paint, oblique fillet, you should think about the quality of this wooden box. All listed is not valid for wood windows, because the product is produced is not good. Date of manufacture. For the manufacture of the present high-quality window requires not less than 3 weeks. If you are offered make a wooden box in a shorter time, then most likely it will be produced in violation of the process. In this case, you should check calculation of order. In addition, again carefully need to check the description, drawings and equipment. Look installation scheme every window, check out if it opens, as you would like. Inattention can eventually lead to misunderstandings. Windows manufacture and assemble exactly as shown in the drawing. Again indicate the presence of Window sills, mosquito nets, check the color of furniture. Value. Here the important thing to remember one thing – quality wooden box is not can be cheap. This is due to the high cost of the technological process of manufacturing windows and materials used. If you offer too cheap wooden window, most likely, some steps process are omitted, and replaced with expensive materials with cheaper equivalents. Of course, all this affects the quality of wooden windows and, consequently, on whether it will please you or upset.
