Construction of sandwich panels - quickly, easily, reliably

The story of the sandwich panels sandwich panels are sandwich structures of two sheets of galvanized or painted steel and a layer of insulation, which are used as mineral wool or foam. Now it is difficult to believe that this popular material for prefabricated buildings and structures appeared relatively recently. Prototype of the first senvich panels are the product, invented by American engineer Frank Lloyd Ryton in the thirties of last century. By the time the creation of light, durable and comfortable items for the construction was a big step forward, but the model needs improvement. These students busy architectural University Alden B. Dow, and soon appeared the first three-layer sandwich panels that demonstrate a number of positive characteristics. But apart from the merits, the new material and had a serious flaw - production takes too much time. The optimal technology for manufacturing sandwich panels has been picked up only in 1960 by specialists of Alside. Since the production of these products were supplied "on stream", and its output will increase the capacity of construction of prefabricated buildings and structures. In Russia imported sandwich panels come in the nineties of the last century, and soon began to appear on plants producing them. To date, our country has more than 200 domestic manufacturers of sandwich panels. Most of the companies produce these products according to western technology with precision classes that meet Russian norms and standards. Types of sandwich panels sandwich panels for prefabricated buildings are divided into wall and roof. Wall panels, as well as the name implies, are used to create wall panels, roof panels are used to organize the roof. Fundamental difference in design of both types of panels not only different density mineral wool filler - no less than 110 kg/m3 for the wall and at least 150 kg/m3 for roofing. Fillers sandwich panels as a filler for sandwich panels using mineral wool or expanded polystyrene (foam). Both materials have low thermal conductivity and good sound insulation, but the panels with foamed slightly lighter models with mineral wool. Because the insulation is secured water-vapor-permeable membrane, senvich panels do not absorb water, but may be susceptible to fungus and mildew. This feature allows you to create a favorable climate in the room, which is especially important during long daily presence in it of people. The advantages of sandwich panels in front of other building materials - brick, concrete panels, wooden blocks - sandwich panels have many advantages. Lower costs for capital construction and installation deadlines - it's possible to buy and erect buildings and structures necessary area and quickly putting them into operation due to sound system installation. In this reconstruction of the building is as simple as its construction. High thermal insulation properties. Sandwich panel thickness of 100 mm provides the same insulation as the brickwork 640 mm thick wall or cellular concrete thickness of 500 mm. The use of sandwich wall panels significantly reduces heating costs during the cold season and retains a comfortable indoor temperature in hot weather. High sound insulation properties make it possible to build pre-fabricated buildings and close to highways, railways, construction sites and other sources of noise without compromising the health of living or working in them. Low weight of panels enables easy delivery of sufficient quantities of this construction material transport. In addition, significantly reduces the load on the foundation that allows for construction without additional costs for detailed study of the soil. Resistance to temperature changes allows the use of buildings and structures of sandwich panels in various regions of our country. Durability of prefabricated buildings - another plus to the previously mentioned possibility of their rapid construction and dismantling. At relatively low cost service life of buildings from sandwich panels are about 25 years. Environmentally friendly and compliance with sanitary standards - the benefits of allowing for the use of sandwich panels for construction of medical facilities and food industries. Modern design and color on both sides - a great opportunity to refuse additional finishing. External and internal sides of the sandwich panels are corrosion resistant and decorative coatings resistant to both mechanical and chemical and weather resistant. The rich colors of coatings to satisfy the tastes of any, even the most discerning customers. The scope of the sandwich panels sandwich panels are widely used for construction of buildings for different purposes. These include commercial and administrative offices, warehouses, cabins, office buildings, sports facilities, garden houses, small shops and factories, even the food industry. In addition to use as building material, sandwich panels are used for insulation and decoration of existing buildings, as well as for the manufacture of fire doors and gates. Convenience, simplicity, reliability and reasonable prices have allowed the sandwich panels to be one of the most modern and popular materials for quick construction of buildings and structures.
