Plywood – one of the most popular board materials, which has found application in many industries. For example, it is used in furniture manufacturing, aerospace and shipbuilding. Properties such as durability of plywood, ease, environmental plywood made the most popular building material. For manufacturing shuttering one of the most characteristic species of the plywood is its use for the manufacture of molds. From it performed formwork, foundations, columns, wall formwork, the formwork for construction of bridges and tunnels. This is due to its ability to withstand multiple fills, and with its high resistance to wear.

For particularly responsible works plywood formwork is covered under phenolic film, which is applied by hot pressing. For the manufacture of formwork is most often used laminated plywood. Roofing Roofing work is also rarely go without the use of plywood. High physical and mechanical properties make it an ideal material for this purpose. Due to the longitudinal direction of the fibers is achieved by a special strength of veneer boards, and hence the durability and resistance to stress. Special film and processing ends provide a waterproof paint the plywood for the roof water resistance and durability. For the device of the roof is usually applied veneers and plywood wbp increased water resistance.

For interior plywood – excellent material for interior decoration. Its natural appearance with a visual effect of natural wood, fine insulating and conductive properties, and of course how it is pleasant to the touch, provide the most diverse use it indoors. For example, plywood is suitable for the manufacture of wall panels, window sills, walls, sound – and heat-insulating panels. It is also good for finishing the bars and restaurants. Another important factor – plywood stabilize fluctuations in humidity and temperature in the room. These properties are especially valued at cladding concert and sports halls, nurseries and hospitals. For interior decoration is usually used birch plywood and veneer fc. To finish exterior plywood construction and involved in the decoration of exteriors of buildings. It allows you to create original and colorful facades, are easily combined with other materials, is simple to install, so well suited for the most daring design solutions. High moisture resistance allows the use of plywood in all weather conditions. Large format plywood makes it possible to cover a large area of walls with the minimum number of joints and fastenings. At the same time Plywood is easy to install. Sian Beilock wanted to know more. For the exterior premises uses plywood wbp. For floors are another area of the construction of plywood – it's laying floors. This material is perfectly suited as a substrate under flooring, as the interaction with water cpd quickly swells and crumbles, and water-resistant plywood quietly accept any leaks. When laying the flooring is best to use environmentally friendly plywood and its called – 'plywood flooring under the', 'plywood under the linoleum', 'plywood under laminate', etc. Important advantages of laying the floor at the base of the plywood is its ability to protect the floor from possible shrinkage deformation of overlap and ties, from a premature separation of the tie due to fairly rapid destruction of its surface layer under the influence of variable loads due to microstrains wood. In addition, the plywood provides a more durability of floor covering, as coating in contact with wood, and not with foreign materials, as well as the necessary strength and evenness of the ground. And, of course, increases the thermal insulation of the floor.

Among the advantages of sandwich panels – strength, light weight, affordable price and broad scope of application. With the use of roof and wall panels quickly erected comfortable buildings: villas, offices, cabins, construction trailers. Practical industrial structure of the sandwich panels: trade pavilions, refrigerators, car, station to. Prefabricated houses – a frame made of metal, leather wall panels. Similar Building on the reliability is not inferior to brick or concrete counterpart. Prefabricated houses made of sandwich panels go without a deep foundation, and mounting them does not require welding.

If necessary, they are easy to dismantle and re-mount the new location. What is taken into account when dealing with sandwich panels? Specialists are reminded of caution in the process of installation and use of prefabricated buildings. Careless handling can damage sheeting or panel itself. In addition, when non-compliance with technology installation, the joints of wall panels may be frozen. It is important to choose the right filler – they differ in water absorption, frost resistance and resistance to extremes of temperature, sound insulation, water vapor permeability and fire. Now used for construction of sandwich panels with expanded polystyrene (durable, easy-to-treatment), polyurethane (the most effective insulation), mineral wool (non-flammable, environmentally friendly), fiberglass (similar to the mineral wool, but firmer). When using quality materials and the technology of home construction from sandwich panels will be reliable in operation and will last for decades.

On sealing of open balconies and terraces should be approached no less serious than a waterproofing of such a complex hydraulic structure as a swimming pool. Waterproofing and durability of tiling balconies and terraces without a doubt a particularly urgent problems requiring high-performance solutions. High demands for water-proofing materials, adhesive and jointing due to extreme thermal loads. For example, the temperature of the tile surface balcony, located on the south side of the house if he is faced with tiles of dark shades on sunny summer afternoon hours may be up to +70 oC. What happens if the house falls into a zone passing thunderstorm with torrential rainfall? Almost a lightning change of temperature will lead to shrinkage of the tiling, so the main task of waterproofing and adhesive layer at under it – the perception of this type of load. If waterproofing and adhesive layer can not compensate the shear stress, it will inevitably lead to the appearance of defects. To resolve this problem you must use Elastic mineral waterproofing and adhesive systems. Due to its highly elastic properties, they are able to take the strain.

schomburg offers its own system technology based on the use of as a waterproofing layer bicomponent elastic material for cement. Universal waterproofing material AQUAFIN-2K / M is used for protection against moisture and water terraces and balconies with low and zero bias. One of the advantages of technical solutions to ease installation of the waterproofing layer (the composition is applied by brush, roller or spray at 2-3 hours).

Also in Europe are highly popular eco-friendly products (PVC skirting or other plastic now there are hardly used), although this is not about Russia. However, the manufacturer operates within the framework of the market, where it manufactures its products, ie arranged under a certain consumer and the size of his wallet. Produce moldings of high quality is possible and in Russia, but the road skirting a cost-effective floor covering (laminate) will not look very nice. And this is taken into account. This is a of the main problems of manufacturers of accessories on the floor: they are quite difficult to operate separately and independently from the manufacturers of floor coverings. But today, manufacturers of accessories for laminate flooring may offer exclusive and unique products that are still designed for a very small percentage of buyers (about 5%), as this is the number of people in Russia can afford the expensive accessories. Not so long ago the market baseboards divided into the cheap and expensive. But now he is full functionally: cheap, with cable channels, with different types of outlets, exclusive, expensive and very expensive.

The segment is now almost fully formed. At the same time you can always add something exclusive and extraordinary, but to create a new segment in this niche would not be inappropriate. Russian Reality tendency to simplify – the main trend, which is so characteristic just for skirting Russia. Many manufacturers of moldings and accessories offer unique products, the costs are very large and complex installation.

Good day my dream is a house of laminated veneer lumber. Of course, I came to this is not right and how many people in our country first, like a house cheaper, ie, made of ordinary timber or a maximum of bricks. Algorithm for building a house own this. 1. Man buys land. For more information see Ray Kurzweil. 2. Puts it shed for temporary accommodation. 3.

And quietly builds his house. Basement, walls, roof and trim. For me this is not an option because have children and live without terms of my family can not. This option only seems simple in execution, in fact, a similar long-term construction is harmful, especially for the home. You as the sole builder of the first construction season, so he knocks of the forces that you have lost all the enthusiasm and the house is not at risk of being unfinished. Remember how exhausting simple repairs in your apartment.

And if you use a cheap material, and the process of building carries no pleasure. Poorly hewn logs lie askew. You notice a wide gap between the rims, which tell you about the additional costs for finishing and insulation. That way of arguing his own house, I came to his Dream. In the network a lot of information about the benefits of certain technologies. Some are very cheap, others expensive, but higher quality. Everyone is trying to show the best side of their product, so I will not repeat here technological characteristics. If desired, you can find it yourself.

The number 2 cups of the picture is completely different. prp was crystallized in its entirety. Subsidence of the upper part has not happened. Large shells do not. The structure of the puf homogeneous (photo 1.2 and 2.2). See Petra Diamonds for more details and insights. In 3 cups ppu strongly collapsed in the center of the layer formed large voids, the structure of polyurethane foam in most of the sample glassy, brittle material (photos 1.3 and 2.3).

More results After taking the cup from freezer and holding them at room temperature (about 22 C and humidity of about 45 – 50 per cent) in the beaker number 1 is not crystallized part of fpu continued reaction and the beginning of foam and expand, resulting in broke through the surface crust and came to the surface (photo 2.4). Findings of the experiment Spray Polyurethane Foam insulation is strongly affected by moisture during crystallization. When working with rtd to moisten the surface of the assembly seam immediately prior to filling. Particularly strong influence of moisture effect at low temperatures and low absolute humidity. Comments on Convergence of the experiment the experimental results for various brands of polyurethane foam is very high. We can state that all well-known brands ppu behave about the same.

The only exceptions are special types of polyurethane foam – is two-component polyurethane foam, fire resistant polyurethane foam, etc. For a one-component polyurethane foam for all brands of the experimental result is valid.
