About Drywall - specifically

The ongoing construction boom in Ukraine has a distinctive feature - its basis is the construction of new and reconstruction of old buildings that meet the more stringent requirements - functionality and comfort, which are close to European and world standards. The ongoing construction boom in Ukraine has a distinctive feature - its basis is the construction of new and reconstruction of old buildings that meet the more stringent requirements - functionality and comfort, which are close to European and world standards. Whether it is luxury homes, apartments of various diplomatic and trade missions, financial institutions, government agencies, offices, a variety of companies and firms, and everywhere we see the active implementation came to us from abroad, modern building technology. One of the most popular destinations in recent years has become perhaps the use of "dry" methods of interior decoration with gypsum board. But to say that they already are widespread, it would be somewhat premature. Therefore, more detailed information about the material - plaster, as well as the technological intricacies of its application will not be superfluous. For objective coverage of this, of course, important and quite timely topic, we have two interviews with experts - experienced wholesaler and retailer-skilled customer-builder. "If you use drywall any redevelopment of premises is not an issue" on the Ukrainian market drywall presented only a few foreign companies: KNAUF (Germany), LAFARGE (France), Austrian-Polish RIGIPS. It should be noted that the company engaged in the sale of gypsum board, in its range are also associated materials: metal frame profiles, fastening elements to them, chamfers, wallpaper, plaster, putty, adhesives, adhesive tapes, tools needed, etc. The undisputed leader on the Ukrainian market drywall is KNAUF, which has here, in Ukraine, its plant Stroymak Knauf and developed dealer network. One of the largest dealers Knauf - Kiev firm Sanders, like the rest, along with other products, offers a dry system. From the executive director of the company, Anatoly S. Pavlenko we. Decided to talk. - Where and how to apply sheetrock and what are its main advantages? - Drywall - a center position in the dry method, interior design and facilities. Plasterboard systems are used according to the standards in hospitals, airports, hotels, restaurants, banks, shops, offices, exhibition and sports halls, as well as in residential construction. Clear advantage of such systems - ease of use of different heat and sound insulation materials, which are embedded between the wall and plasterboard. The second advantage concerns of various communications - electrical, plumbing and any other. That is, all pipes, cables, wires hidden under a sheet of plasterboard, and access to the most simplistic. But most importantly, that these systems are lightweight, so there is such a big load on the floor, like brick walls. Consequently, the frame house and foundation can make a lightweight, which significantly reduces the cost of construction. Plus, the plasterboard of the systems, like clay, you can sculpt anything from them, you can create a variety of forms - wavy, zigzag, etc. Do something like that of a brick - a very difficult and expensive, and plasterboard - much easier and cheaper. - Are there any difficulties in working with gypsum systems? - There are no special difficulties in installing drywall constructions there. If a person hands and head, except for descriptions of him do not need anything. The main difficulty - the correct markup. The only thing working for puttying joints requires a certain qualification or experience. - What if someone needed to restructure its premise that any change or change in the interior? - It is always welcome. After all, drywall is not fixed "tightly". Sheets are inserted into the guide slots and bolted to the frame with screws and dowels frame is nailed to the wall or ceiling. Additional mount - rack profiles, struts. But the whole system differs a great strength, mechanically destroy it - unlikely, but it is easily and quickly dismantled and therefore any redevelopment of the premises was not a problem. - What are the standards for drywall? - Drywall is the following: GCR - ordinary, standard; plasterboard - Refractory; GKLV - waterproof; GKLVO - fire and water resistant. Sam plasterboard is a length of two to three meters. There is a light 9,5 mm thick and has a standard - 12,5 mm. There are also special sheets of 15 mm, which did not yet have enough demand, and therefore are not produced in Ukraine. - Is there a difference between the plasterboard, which is produced in Germany itself, and our, domestic? - In Germany, producing more varieties of gypsum board, including for protection from X-ray and radioactive radiation. The Germans even make bullet-proof system using plasterboard. Its size - 1,2 m, the edge comes standard. However, it is unlikely that these specific and very expensive materials can be someone in our interest, at the present time, our customers seek to maximize the reduction in price of construction. Drywall, which is produced in Ukraine, manufactured on the same equipment and the same technology as all the other enterprises of the company KNAUF around the world, and to the same degree of eco-friendly. True, the company's factories in Germany KNAUF there are some technical differences: in the manufacturing process in the pulp - roughly speaking, the original mess - which is the basis for the production of gypsum core adds cellulose. It should be noted that in Ukraine, manufactured gypsum board is much cheaper than imported from Germany, but for all its technical parameters practically it is not inferior and can get quite smooth and flat surfaces of various configurations - curved, concave, etc. - But before the Ukrainian drywall was fair criticism. What happened then? - Indeed, at the very beginning of plant Stroymak Knauf, at the stage of implementation and development of technology, there were some difficulties. For this reason, the objective quality of domestic plasterboard was, of course, worse. But now there is almost no difference, and soon it will actually be reduced to zero. - What else besides technology, affected the quality of the drywall? - Quality of drywall in the first place, provided raw materials. In Ukraine, it falls from Moldova, from the quarry where the chemical composition of gypsum is somewhat different than the Germans, in which there reagips (product recycling thermal power plant). But in Ukraine in its application is practically unnecessary. - It turns out that we are totally dependent on imported raw materials? - Not quite - near Donetsk company KNAUF bought mine, which will soon begin to be developed. - And how are things on the already existing plant? - Kiev factory "Stroymak Knauf nowadays no longer cope with the volumes that are dictated by the market. Therefore, as soon as power plant is scheduled to increase two-fold. After the reconstruction of the plant to quantify the problem of drywall will be fully resolved. The plant will be fully able to meet the needs of the entire country. - Certainly, we have fans exclusively imported products. What should they? - Indeed, individual firms, which perform an exclusive deal with costly repairs and design, insured and did not want to risk becoming drywall, made directly to Germany. Therefore, the German plasterboard there is a small but steady demand. And by the way, "Sanders" - the only firm that it meets. - Could you describe the state of the market drywall in Ukraine? - Need for the construction market of Ukraine in the plaster on the date of 13-14 million sq ft per annum. The 2003 projected - 18 million square meters. m, on the basis of further increasing the demand for this material due to its wider application in construction. - So what prospects you have a rainbow? - The potential is big. Many regions of the 5 years ago did not even know what drywall. Therefore, some time for initial review and gradual adaptation to the new product must inevitably pass. And only then can we talk about realizing this potential. - What are you doing this to most initial introduction and addictive passed as quickly and painlessly? - KNAUF Company proposed to introduce in all schools in Ukraine building a new specialty - drywall installer, designed for her training program, has released a textbook, which had already carried out training and retraining. This is a completely new approaches that involve and cooperate with the State Construction Committee. Already there are building codes for design institutes and organizations that use gypsum as a finishing material. - What advice would you like to give to your customers? - All buyers drywall systems is very important to be familiar with all applicable expenses. Keep in mind that an average of 10% must take stock, because the ideal of walls, ideally placed in the construction process does not exist. When you trim some pieces inevitably discarded. However, on the other hand, the same area can be calculated correctly and incorrectly. In addition to working with sheetrock needed additional materials. In general, they also take from the reserve. Suppose, for 200 m sheet conventionally necessary 3-3,5 bag of glue or putty-biggest construction company can afford to buy and much more, because the remainder will go to the next object. But there is a buyer who may, once in a lifetime is something to build, and honest sellers have to sell him so that he has virtually no choice of materials. Otherwise, it will be wasted money. Our company makes payments to its customers, given all these details so that they themselves or their colleagues have again come to us. "Many of our construction companies and firms are not willing to work with advanced technologies" Learn about the prices of gypsum from different manufacturers, and compare them you can quickly and easily by referring to the price list published in our magazine. But unwittingly it begs the question what kind of stuff better, that it is preferred for a particular type of construction? Here, the opinion of the independent expert in very handy. We therefore seek clarification from the employees of the firm "independent expert" Vladimir Mikhailovich was black. But our conversation immediately went to bed quite unexpected and led eventually to some paradoxical conclusions. - Do you think that any product manufacturer is the best? - The main problem of complex systems of drywall is not in who they buy, the manufacturer of some of the country preferred. Even "pure" German board, directly from Germany itself, does not protect against poor-quality paint or gluing of wallpaper, from holes and cracks, if not immediately, then some time later. From something bullets do not do it, but it happens and vice versa, even from bullets can get something quite the opposite. - In what cases the application of gypsum is most advisable? - Here, above all, must be a clear separation. When it comes to residential premises, there will definitely be preferred the old traditional way of cement, despite all its shortcomings. If only because the operation of apartment, sooner or later arises, for example, need to make friends something on the wall or outweigh, say, a shelf, a picture, etc. In this case, to get to the free wall space, not knowing the location of the guide, it is difficult. A cement the already existing hole and the harder, although manufacturers gypsum board and offer for these purposes a number of relevant materials. However, drilling a hole in a wall seems rather risky. - What other problems can arise when working with sheetrock? - There is great danger that the piers of the drywall sheets might lead cockroaches. Of course, if everything is perfect fit, and there will be no gaps or holes, this is completely avoidable, but then list even without noticing it, you can easily break, and then the owners will be persistent pest. So much for the apartment walls. Another thing - finish ceilings. Today, few of our builders are able to do quite smooth ceiling, and it costs a decent amount. Consequently, the plasterboard ceiling finish - cost is justified. It turns out cheaper and much better. A decorative ceiling with all sorts of decorations is only possible with the use of drywall. - So you think that the use of gypsum board, except the ceiling, the repair and construction of new housing, would hardly be expedient? - If you calculate the cost of all the processes inside and out, it turns out very expensive. After all, should be taken into account except the sheets, at first glance, like, and not-so-expensive, there are the accompanying costs. Because as you have to buy more and guides, hardware, related materials and tools. Layout, grouting, installation requires a sufficiently high qualification and appropriate payment. Then often finished surface exposed to additional processing, especially if the walls are under painting. That is, there are additional processes that cause additional costs. - It turns out that the drywall does not give economic benefits? - Make a conclusion about the special economic benefits derived from the use of drywall in the building for no reason. But increasing the speed, quality improvement and the elimination of many, many inconveniences they will definitely give. - Apparently, it is crucial for the formation of consumer preferences? - Undoubtedly, the functional and industrial premises - plasterboard has all the right to life. This is really class! For office space, the same thing - well and good. But for final conclusions, we must all carefully calculate. For the reconstruction of old buildings - are among the figures, and for new construction - are quite different. In addition, it should be, which will provide room: will there be some sort of production or is it - the future showroom. Various operating conditions also significantly influence the choice of necessary construction materials. And the debate about what products manufacturers (from the selection in the domestic market plasterboard) is better - the German, Austrian, Polish, Russian or Ukrainian, in my opinion, meaningless. Because, first of all, the main and decisive importance is not the material itself, but strict and strict adherence to the proprietary technology and instruction at all, without exception, during the construction. - Can you give any specific examples of violations? - Please, here is the first example: the company KNAUF gives a clear prescription as to store drywall. And if you put the warehouse with high humidity, it must some time must lie down in time to give away excess moisture. Failure to comply with this elementary rule leads to a distortion of leaves and, consequently, to an apparent marriage. Unfortunately, to identify the time period that is necessary in order to catch up with drywall humidity humidity of the room, quite difficult. There has to rely on their own intuition. The second example: few of our builders drew attention to the main point that is associated with temperature control. The instructions written in black and white, that the temperature of the room when working with gypsum board should be stable and in no case lower than 10 degrees Celsius. In these very same conditions, drywall must be located at least 4 days (2 days before and 2 days after installation). And, last but not least, without any further processing. But in practice, the workers, no matter what the temperature differences and not allowing the walls to stand mounted, immediately rush to plug the seams, glued ribbons, etc. What happens next, you might guess. - Are there other typical deviation from the technology? - Of course it is. To get, say, a quality wall to the right to cultivate it. Any manufacturer of plasterboard gives detailed instructions on processing rules after the installation of cardboard surfaces. And they are different: under tile - one, under the wallpaper - the other, by painting-third. And if they do not stick, the result can get a whole bunch of trouble: tile falling off, swell wallpaper, paint, etc. luschitsya - And what is the most common and fatal error? - The most common and are not amenable to correction of the mistake committed so many builders and contractors is that completely ignored the compatibility of materials from different manufacturers together. That is, if you purchase drywall of a certain manufacturer, then everything else - the paint, putty, plaster, etc. should be purchased only in accordance with the manufacturer's recommendations. But out of ignorance or for reasons of excessive cost, many consumers on this nuance is constantly "burn", resulting in unexpected losses. - Are there more subtle technological features, which are known not everyone? - Speaking of "little things", we should mention the fact that at the joints between plasterboard and other surfaces differ from it must use a special adhesive tape. Because without such a need to separate in the places of contiguity of gypsum to foreign materials in two or three months, cracking guaranteed. - What would you like to say in conclusion to our readers? - Customer should not always and in all rely on the contractors, subcontractors, and all sorts of middlemen and blindly trust them. Not uncommon for many of our construction companies have resorted to a deliberate violation of technology for the sake of downright trickery. For example, where you need to put special profiles - to become a regular. Anyone out there sees ... Or lay in the budget materials by a wide margin. And after a few orders from them is so much material that it is possible someone else to make repairs. Many of our construction companies and firms are not willing to work with advanced technologies. Ask for the interest in any firm engaged in construction or repair, if they have a quality system certificate? Certainly, in most cases the answer will serve genuine surprise, "What is it?" Once I had the opportunity to accompany Czech builders who wanted to see our so-called "renovation". When they looked at him, then shrugged and said that they have at home it is called - normal repairs. But this is rather to our common ills that go far beyond the topic. REFERENCE "BM" Gypsum - beautiful building material with a rich past and promising future. Its production and use does not adversely impact on the environment. In building materials, made of gypsum-based, excellent physical characteristics, and among other things, provides high thermal and sound insulation. Gypsum has the ability to "breathe", ie absorb excess moisture, and conversely, to provide it with sufficient moisture. It is noncombustible and fire retardant, it is odorless and electrically neutral, also does not contain toxic elements or compounds, and not without reason was so widespread in orthopedic and visual arts, where there is direct contact with human skin. REFERENCE "BM" "Dry" Methods interior decoration with gypsum board used to align the surfaces of walls, ceilings, interior partitions device. Plasterboard is a kind of "sandwich" consisting of the two sides lined with cardboard core, which is used as a filler the natural gypsum with special additives (plasticizers and modifiers), necessary to give it the required functional characteristics.
