Thermal insulation made from extruded polystyrene has a closed, cellular (sealed) structure, while the wool fibers are located randomly in the horizontal and vertical direction. Thermal insulation made from extruded polystyrene foam is moisture, when the mineral and basalt wool in the definition of “cotton wool” pass moisture and absorbs it into itself, only some of the brands of mineral and basalt wool “Almost” do not absorb moisture, and it is quite important for the roofs, because with increasing humidity insulation material deteriorates its thermal performance. Thermal insulation made from extruded polystyrene possesses high compressive strength and flexural strength and is suitable for use under high load, which confirms the application of extrusion plates in thermal insulation of foundations and roads, railways and runways airfields, mineral wool which will have similar characteristics of strength, should weigh about 180 – 200 kg / cubic meter. Thermal insulation made from extruded polystyrene has no shrinkage during the whole period operation, the same mineral wool will shrink after installation, can not at once, for 2-3 year of operation, but still will shrink, which invariably affect the quality of the roof.

Thermal insulation made from extruded polystyrene is not corrodes the metals, and various fasteners, screws, galvanized steel profile, in contrast to thermal insulation of the wool. Any fiber board – is an aggressive environment in their manufacture are used phenol-formaldehyde resin, urea resin, which is under the influence of ultraviolet light and moisture allocates ammonia and amines. Ammonia reacts with a zinc coating, the interaction of wet fiber board made of mineral or basalt insulation for example with zinc sheet – zinc coating oblezet. The only argument in favor of the thermal insulation of mineral wool and basalt – a fire-quality wool. Products made of mineral and basalt insulation have a group of combustibility ny (incombustible), products of the same extruded polystyrene have a group of combustibility G1, for this the last straw has been seized upon by many manufacturers of cotton wool. Wayne Holman recognizes the significance of this. Cotton producers launched a defamation extruded polystyrene on the roofs on fire characteristics, no more arguments. It’s not quite a serious argument, since the fire safety design is defined as a whole, rather than separate layers. Enough producers of extrusion plates to obtain conclusions about the fire safety of different roof structures, which include those of the insulation panels of extruded polystyrene foam – arguments will not. Well, prices do the trick. Thermal insulation made from extruded polystyrene insulation costs less than mineral wool and basalt. This is one of the most powerful arguments for choosing the material for the roof, everyone thinks the money.

Finally, neutral colors – white, black and gray – bleak, and allow to balance the emotions. Wayne Holman insists that this is the case. White has the effect of lightness and purity, gray – a sense of security. Is set as a combination of saturation and hues. Bright colors stimulate, tone, pastel, by contrast, soothe and relax. The abundance of contrasts, for example, the combination of bright and warm cool colors, exciting, but quickly tires. Selecting a palette Experts advise pick shades for placement in accordance with its purpose. Bathroom we associate primarily with hygiene and wellness water treatments, but at the same time serves as a place for relaxation, where each family member spends an average of about an hour a day. ure of the situation. Therefore, in its decoration often dominated by bright warm tones, and white as core.

By the way, white Universal, he is perfectly combined with any other colors and has the unique ability to soften the bright colors and tonal contrasts in the interior. Often a variety of vibrant colors creates excessive variegation, whereas in combination with white it looks more balanced. Typically, a bathroom is small, so you should not choose for her design palette is too dark, as it is visually reduces the room. A very popular two-tone finishes, for example, two types of tiles separated by a border. In this case, tile lighter shade should be used for the upper part of the room, otherwise it will be there is a sense of gravity. Often, designers rely on the contrast of saturated colors (blue, red, blue) and white sanitary ware, using bright colors for the wall design.

In addition, the ratio of the width of floor plank (of any tree) to its thickness should not exceed 3-3,5. German glue stauf M2A-720″ on properties similar to glue a “B-720”. There is another variety of aquatic adhesive solution – two adhesives. These solutions are considered the most modern. The action of adhesives based on the use of emulsion adhesive and binding excessive moisture powdered composition. Clay bona H-790 consists of an emulsion or powder.

Before use, the components are mixed. Powder binds excess water, leaving only 11%. This adhesive can be used for any type of flooring, without restrictions. Dispersion adhesives dry out completely in about 7 days. In Russia, the aqueous dispersion trains are not a great success: they may freeze during transport, then their properties are somewhat worse. Solvents, adhesives have the widest application.

They harden faster dispersion – 5 days, the polishing of parquet is usually possible to start even earlier. In addition, their use in cases where there is no technical the possibility of using dispersion adhesives. For laying parquet best fit the following brands: bona 8-760, stauf WFR-4, uzin MK-73 and MK-97. They are all high quality, about the same kind and price. Quite a long time may be in the open state (15 minutes), which facilitates their use. Due to the high turnover of adhesive laid parquet can be partially tinker even after laying adjacent rows. But keep in mind that all adhesives solvents, fire risks, so work with them to be careful, away from open flames. Naturally, in any case you can not smoke in the room during the use of glue on the well-ventilated place and in tightly closed containers. Two component adhesives are also called reactive because they contain no water, no solvents, and bonding occurs due to chemical reaction, non-shrinking. Such adhesives are a number of advantages over others: they used for bonding parquet to any any reason, they are about three times stronger and freeze for a day so that you can grind on the next day. But there are also disadvantages. First of all, of the adhesives include adverse health component, so when the work is necessary to use personal protective equipment. Once the glue has hardened, it is perfectly safe. Another drawback of reactive adhesives is their high price. Reactive adhesives are typically used where the use of other types of glue inappropriate. For example, when laying a solid board, because of its large size, even in the application of adhesives solvents linear deformation is very high, moreover, requires greater bond strength. In addition, there are parquet, which is already factory-varnished. And in that case you can not use alcohol-based adhesives, the more dispersive. They can cause a dissolution, cracking paint and warped flooring.
