Folds on air for any thickness of metal and method of production must be satisfied with nyatsya cutoff. Standing seam joints should be the same width throughout the length and must be uniformly dense upset. In the standing seam ducts, as well as maps of the cutting should not be cross-connection joints. On straight rectangular duct with the size of the cross section of more than 400 mm to increase the rigidity of the ridge should be done in increments of 200 to 300 mm around the perimeter of the duct or diagonal creases (ridges). When the amount of cross 1000 mm, in addition, must be provided outside the scope of rigidity.

Framework rigidity must be securely fastened with rivets or spot welding. Elements of fittings should be connected to each other in zigah, seam, welding, rivets and the way puklevki (indentation). Elements of the metal-fittings to be joined together at seam. Zigovye connection for systems that transport air of high humidity or doped with combustible dust is not allowed. The connection of individual parts of ventilation systems perform wafer method (banding, nipple, bell-mouthed, rack, telescopic, with viniplastovymi couplings, welding) or flanged (made of strips, equilateral angle steel, bent corner profile made of galvanized steel sheet).

The connections should be off-governmental and tight. Connection details of the ventilation systems Class II should be performed on the flanges. Fixing flange ducts should be done with persistent flare zigom for welding, spot welding, by rivets or puklevki diameter of 4 to 5 mm, placed in 200 or 250 mm, but not less than four rivets. Fixing flange ducts of metal-crimping should be done with persistent zigom. In the ducts, conveying an aggressive environment, securing flanges with zigov not allowed. Duct wall thickness greater than 1 mm flanges may be stick to the duct without flanging fixing tack welding with electric arc then sealing the gap between the flange and duct. Original

To alpine garden always look decorative and pleasing to the eye, it is necessary to choose the right plants that will make it a green base. Flower design rock garden – very specific kind of gardening, and justify the costs (both labor and materials) may only its decorative high throughout the season. Before you choose a type of floral arrangements and pick up range, you need to comprehensively evaluate The territory allotted for rock garden. Plants alpine garden alpine garden plants have a special charm. The peculiarity lies in the fact that a relatively small area of land you will be able to put a huge variety of plants. All the plants are alpine gorkinizkoroslye and compact and at the correct location and they take care of them, your alpine garden will be a true jewel of your garden.

Starting Planning alpine garden, decide for yourself two things: which plants will be planted and how to organize their placement on the site. Identify plants as alpine gorkimozhno growing in mountainous areas. Homeland of such plants – Alps, Himalayas, etc. Apennines mountains. But in fact, the alpine gorkahili alpinariyahvyraschivayut plants, mainly grown on the coast and some of the 'flat' plants. Some sources propose to refer to the alpine plants that can thrive on rocky soils. But the correct choice of plants dlyaalpinariyavy do, if you open the relevant section of the garden directory. Here you will find an impressive assortment of perennials, dwarf shrubs, dwarf conifers, as well as a variety of colors alpine garden.

Alpine slide, just like any other area of your garden, has its own secrets to care, selection of plants and their cultivation. For example, when selecting plants to avoid unpretentious, but very active in influencing the 'neighbors' plants, such as obrieta, rezuha, yaskolka, mylnyanka and the like. Not my accent attention to the whimsical, demanding winter shelter plants. Looks great and does not need special care atsena, yarrow, columbine, cat paws, asters and many other ordinary, whose list is big enough. A what about the beauty of the mountain pine, dwarf shrubs varied, such as azaleas, some bulbous plants. Accommodation Alpine rasteniyne less important. Wherever you have organized the alpine slide, remember that Plants need a well drained soil with the addition of gravel, periodic pruning and weeding of weeds.

Old houses can be divided into several types: pre-revolutionary building, the post-revolutionary buildings, "Stalinka"; brick, panels, building is an architectural and historical value. Perhaps check out isearch for more information. Pre-revolutionary buildings – usually wooden houses with wooden floors and walls under the plaster. One of their features – the difference between (and sometimes – considerable) size of window blocks the size of the openings. For even more details, read what MyGlobalSearch says on the issue. At installation of windows during the construction of the gap was mounted frame of thick timber, which is already installed window assembly. Above the bar organized an impressive thickness of the plaster soffits. Over the years, old wood under the cracked plaster gradually izgnivaet, and sometimes turns into dust. When removing the windows have to break the plaster soffits and wooden box apart.

The result is a gap in where nothing to strengthen the window unit. In this case, the installation of window units provide pre-installation of the wooden box that is attached to the walls on the long fasteners. The walls of the houses built after Revolution, usually made of bricks and then plastered. She also formed slopes, and under a thick layer of mortar is often hidden all the same doborny board. As a result of the dismantling of old windows in a house aperture is obtained, where the perimeters of the outer part of the opening is much smaller than the inside, and the window sizes obtained from the measurements of the outer quarters, will clearly be an underestimate. Dismantle sill also presents the "surprises": sometimes under the wooden window sill board is ten inches of tow or other filler. Often this was due to the fact that during the restoration of old houses raised floor, and hence the window. The height of the window units had decreased, and window sills to raise all available at the time of ways. Naturally, when removing the tow must be removed and an opening to lay the masonry, which can be mounted in window frames.

It is known that some iron and its alloys because of thermodynamic instability susceptible to oxidation by water and oxygen, resulting in a well-known to all the rust. If the medium, surrounding the product of a metal contaminated with various chemicals, the corrosion process is greatly accelerated. As a result of corrosion of metals industrial countries receive damages of up to 5% of gross domestic product. Corrosion protection of traditional methods, including through the application of paint (the simplest based on GF-021 primer and enamel PF-115 and more sophisticated and expensive coatings) are not always appropriate. For example, for repair coating of metal can not be stopped for long term traffic on the bridge, requiring repairs. Speaking candidly isearch told us the story. Also, it is uneconomical to Remove Hardware, continuously working in the technological process of production. It should be borne in mind that the cost of preparatory work to clean up metal from rust, scale is quite high. Attempts to applying conventional paint surface covered with corrosion lead to disastrous results, as traditional materials do not provide sufficient protection, and the corrosion process in this case becomes uncontrolled visually. Get more background information with materials from myglobalsearch.

Today produces a wide range of special coatings, applied directly to rust. This water-borne primers and primer paint containing orthophosphoric acid, chemically transforming rust, and organorazbavlyaemye two-component with a hardener (universal anticorrosive composition "Gremirust", "Cornick"). Developed and manufactured and single-component quick-drying materials that can be applied directly to rust (priming enamel AU-1-201-1518 enamel AU). These materials are added corrosion inhibitors and a variety of target agents. Water-based materials are environmentally friendly and cheap, but can not stand requirements for a high decoration. The coatings based on waterborne materials usually dull, do not have a wide color gamut. Polyurethane paints and varnishes (enamel primer SD-1-202-enamel SD 1524) best meet the high demands for protection from corrosion. These materials protect the painted surfaces of over 15 years in an open industrial atmosphere temperate and cold climates. It should be borne in mind that before applying a decorative protective coating on the metal surface with traces of corrosion, you must first remove loose, loose rust, reducing the adhesion of paint.

It is well known that oil paint – it's almost archaic construction. She can not paint the walls in a residential area. It is not recommended to paint the doors and windows. It does not work on the ceilings. But.

But while oil-based paint remains our constant companion. Removing old wallpaper, layer after layer, you will stumble eventually neizvenno a concrete wall, painted with oil paint. By removing the tiles in the ramshackle bathroom, you gaze rested on nakzhe old layer oil paint. Free cell phones may not feel the same. Even turning off the worn linoleum, you still will not go away from the layer of oil paint, which sometimes covered the floors. Determine our relationship to oil paint is difficult. On the one hand, it causes a lot of trouble to those who want to get rid of it. But, on the other hand, the material in some cases are unmatched in their characteristics primer. Before you determine who is oil-based paint for us friend or foe, will pay 'vinovnetse celebration' some attention.

Even in the recent past, oil paints were most prevalent in our country. They painted everything and anything. At least at home. Alternatives almost was not. All waited patiently for several days until the end process of curing of paint and the smell was perceived as a matter of course. Meanwhile, oil paint does not breathe, not only individuals but also surface, so a few years (if not a year or two) the film begins to peel and fall off. Today, among the applications of oil paint can only whiten the surface of the metal, as well as walls and ceilings premises (for example, WC). True, in these rooms suit hood. Chuchityvaya the fact that even modern bathrooms stations prefer to let the unpretentious brick, but all the same tiles tiles, as well as taking into vnimnanie widespread plastic windows that do not need paint, the production of oil paints, the ideas, would have been stopped.

Durability log (and price) directly depends on the type of wood. Dear larch lasts about twice as long as relatively inexpensive pine. At the same time, larch, which has a greater density, better conductor of heat. In order to provide the same teplosberezheniya as log house out of pine logs with diameter 24cm diameter logs of larch should be 28cm. Sometimes the lower crowns of felled larch, and more – made of pine. Erection of wooden frame requires slowness in the future arrangement and decoration, as after assembly 'under roof' must stand for a year or more.

During this time, dry timber and the house settles. Who wants to build a house from log cabins to know that the walls of log homes as wood shrinkage, mainly during the first year after manufacture at home, give a draft of which depends on the initial moisture content of logs, ranging 1/20-1/130 height Wall log home. Only after the precipitation at home you can start re-konopatke (caulking, install windows and doors, make trimmings. But 'game worth the candle stands': in fact, it turns out the house for ages. Others including isearch, offer their opinions as well. One of the most important steps in building a log home is chopped konopatka walls.

Insulation is placed between the logs once during construction. Commonly used moss, hemp, felt, hemp, jute and other fibrous materials. However, the peculiarity of chopped walls is that they give considerable shrinkage, which leads to decompression of the walls to reduce their insulating properties. If this has piqued your curiosity, check out Cell Phones. It turns out that without having to work with sutures without konopatki (seal gaps) can not do. Konopatku can be performed in two ways: 'a set' and 'to stretch'. Konopatka 'to set' is that of a fibrous material make long strands that are twisted in the shaft desired length, which rammed into the gap. Konopatka 'to stretch' is made of individual strands that are laid fiber across logs (dangling ends of the fibers are selected, rolled in a roller and hammered into the groove). At used as a sealant felt should take care to protect it from moths. As a rule, the final konopatka and walls done in a year and a half after the completion of construction of the house. At upholstery home clapboard siding, or (this is done, of course, after the final shrinkage) under the lining layer of insulation is recommended to lay (URSA, ISOVER, ROCKWOOL, etc.). In this case, in a wooden house to live all year round. Such log house will be warm and durable. The tree has almost ideal characteristics for building. In a wooden house cool in hot weather and warm in the winter cold. In addition, this home is durable, relatively easy to install and environmentally friendly.

The fact is that the alignment of the dry wall and ceiling eats at least 7-8 cm from the surface that room 20 m2 is approximately 1.5 m2. On the other hand, even if we take no minimum layer thickness of 1 cm, which allows plaster applied technology, and the middle layer of 2 cm, then the same area of a room of 20 m2 to a maximum reduction of 0.5 m2, or three times less space. If we consider that the technology is applied dry repairs around the home, the easy to calculate that for a flat area of 100 m2 this difference will be from 7 to 10 m2. And it's – about 10% of the total area. However, speaking of the advantages of plaster, it should be noted, and its shortcomings. This is especially high, according to Compared to other technologies, the complexity of plastering work, especially on the ceiling, and as a consequence, a significant increase in terms of repair. Various methods and techniques of plastering can use them to achieve different decorative and structural effects. Firstly, well plastered surface in combination with decorative plaster to create a structural coating with the desired effect.

Second, the finish wall photo on the wall will be a smooth flawless look like the most delicate and inexpensive paper wallpaper and silk textiles. And finally, third, – plaster provides an excellent opportunity to issue space, seeking expression. Execution and simulation of various architectural and decorative elements (arches, half-columns, cornices, niches) create a special interior space into which fit perfectly into a variety of styles, interiors, well, to example in the design of the corridor. Isearch contributes greatly to this topic. It is important that the plaster can not build a completely unwieldy for any modern apartment architectural details, but only to designate them on the surface with the plastering. From this point of plaster as a waterproof base completely indispensable in areas with constant high humidity, above all – in bathrooms and kitchens.

Plaster does not require a social given or created by her amounts, it naturally draws already available, even the smallest surface, thus maintaining the maximum pre-existing space. In conclusion, the technology implementation of plastering work. Credit: MyGlobalSearch-2011. It is quite simple, Of course, if you have good masters. The ability to display all the millimeter, constantly and meticulously checking the appearance of the ceiling and walls, intuition and artistic skill in working with such a demanding plastic material as plaster, make this type of repair work in an art form. If execution of the floor screed does not always require highly skilled labor force (such as the use of technology screed with self-leveling compounds), the plaster walls, slopes, and even more so the ceiling can be trusted only to highly skilled craftsmen. Ceiling when the plaster work requires special attention. Reasons must be completely cleared of all existing layers of old finish on smooth concrete knurled special diamond tool. Necessarily require a special primer, after which the foundation is strong and rough. The quality of the plaster to a large extent determined by the selected primer and method of its application. Almost all the good artists have their own know-how on the subject of how and what prime surface. After the primer is attached to the ceiling required a special plaster mesh, and then leveling the ceiling and made the device lighthouses on it. It then renders the core layer, followed by Final stage – its grout.
