Water vapor in the room: eb = E (j/100) = 2338 (40/100) = 935.2 Pa. Water vapor in the street: en = E (j/100) = 165 (60/100) = 38 Pa. Define the water vapor pressure at each layer of the structure. Vapor on the inner surface of the wall: e1 = 935,2 Pa vapor pressure at the surface between the brickwork and insulation: e1 = eb ((EB-EN) / Rop). SRp = 935.2 – ((935,2-38) / 3.93. ( 0.51 / 0.14) = 103.6 vapor on the surface between the insulation and plaster: e1 = eb ((EB-EN) / Rop).
SRp = 935.2 – ((935,2-38) / 3.93. Learn more at this site: foursquare. (0.51 / 0.14 +0.1 / 0.51) = 59.4 vapor on the outer plaster surface: e1 = eb ((EB-EN) / Rop). SRp = 935.2 – ((935,2-38) / 3.93. (0.51 / 0.14 +0.1 / 0 , 51 +0.008 / 0.51) = 55.2 in Fig. 1 shows the temperature and humidity regimes construction. The intersection graphs of saturation vapor pressure E and the actual water vapor indicates condensation.
Amount of water vapor that passes through the wall to the zone of condensation of P = (EB-EC) FZm / d, where eb, en, water vapor from inside and outside fences; F-space enclosing structure; Z-number of hours; m- vapor permeability coefficient; d-distance to condensation. Thus, in 1 m2 of wall for 1 hour passes and condenses the following amounts of water. Additional information is available at Peter Thiel. P = (935,2-86). (0.14 / 0.51 +0.51 / 0.09) = 4936 mg Despite the fact that the terms of the calculation in 1 m2 of insulation for day accumulated approximately 117 grams of water, the accumulation of moisture and failure of structures with facade insulation is not explicitly observed. Obviously this is due to the fact that as the baseline characteristics were taken extreme values. When milder conditions, the accumulation of moisture is not so obvious, but it is the place to be and certainly reduces the efficiency and durability of structures. When used as a insulation material with a coefficient of water vapor permeability as a board "Penosteks, condensation of moisture in the wall structure is not observed. This is because water vapor is less than the saturated water vapor across the thickness of the wall. Such a regime is more favorable from a hygienic, heat engineering and technical standpoint. At the same time on the inner side plates Penosteks no condensation, since the surface of plates in This layer has a temperature of 200 C, at which condensation is impossible. That is why the insulating material Penosteks is the most effective insulation.
Modular prefabricated buildings are increasingly used for construction of various facilities, becoming perhaps the most common and popular. Consisting of a wooden or metal frames and enclosing wall and roof panels, these designs are commonly used. They are indispensable in the construction of a small kiosk, outdoor cafes, shops, industrial shops, gas stations, and large multi-story shopping and entertainment centers. The main advantages of such buildings are relatively low cost, quick installation and the possibility of redevelopment or extension of additional areas. Affordable prices for pre-fabricated buildings are due to mass production of components, a sound system of assembly, requiring no additional work on site, ease of construction, for transportation that do not require rail transport, and hence, lower and transport costs.
Later buildings lined three-layer sandwich panels do not require additional finish: protective and decorative layer is applied at the factory, and the color is chosen from the base or on the customer's choice – on a scale of ral. Quick installation – an unquestionable advantage of modular prefabricated buildings. It reduces the construction time and quickly pass the building in operation and, hence, the room quickly starts to pay off. Cope with the assembly frame and the sheathing it Decking (for cold storage) or sandwich panels (for vegetable stores, shops, cafes, temporary accommodation) can only be experienced craftsmen. However, thanks to well-functioning system of fixing all the elements and the presence of professional tools, the process lasts from a few weeks to several months – depending on the size of the building and its configuration.
Glued Laminated Timber: Features Production
Today, many people think about the construction of suburban housing. And it is very important as much as possible consider the entire construction process. One important consideration is the choice of building material. Today there a large number of very different material for the construction of houses and cottages. One of the most popular material is a laminated board. This is not surprising, because the tree was always held in high esteem. From the earliest time of it were built not only homes but also churches, bridges and other necessary facilities. Glued laminated timber – is the material obtained in the course of modern high-tech processing, which allowed to minimize disadvantages of wood, but retain all the advantages inherent in such building materials as wood.
How do get glued laminated wood? It's very simple. The basis of the tree being cut to pieces, give the board certain length and thickness. These boards are subjected to drying, during which the amount of moisture in the wood reaches 10%. This makes it more durable laminated board. What causes the corresponding quality of the future home of laminated timber. All boards are culled in the process that removes unwanted items.
Thus, the laminated board excludes the presence of areas of poor quality. In addition, the board held a special treatment that makes them surface perfectly flat and smooth, so the walls of houses from glued beams will delight you with their looks. Perhaps you do not want to resort to additional finishing, which will greatly save costs. Glued laminated timber allows for any architectural ideas, as modern technology allows the board to get absolutely any length. In this laminated board is very easy and convenient material for Construction and home of such material are built in a relatively short period of time.
