Let me explain just a moment on the use of polypropylene for heating systems. It is believed in my view mistakenly, that you can use reinforced polypropylene. No doubt this story many times more reliable than conventional polypropylene. But – in the market there are no reinforced fittings! The conclusion is simple: the problem of conventional PP remains – now in the joints. 3. Linear expansion of plastic pipes win here no doubt: a very low thermal expansion material – when heated at 1 C yield elongation of 0.02 mm. for each Meter – allows more aesthetically pleasing to hide pipes, saving space.
To save the metal-tube stock to change the volume, it is placed in a special protective case, a little more than pipe diameter. It enough to keep all repairs on the outside and all the pipes hidden under otdelku.Polipropilenovye tube, with the exception of reinforced, give a decent thermal expansion – when heated at 1 C yield elongation of 0.15 mm. for each meter. Accordingly, in no case can sew polypropylene tubes for finishing back to back: when the tube starts to "play", changing its original size, finish will be lost. 4. Thermal conductivity. For metal tubes are characterized by high thermal conductivity. This makes them more suitable for use in heating sistemah.Odnako polypropylene tubes, due to the low thermal conductivity, have an undeniable plus in water supply (they better keep the temperature of the water) 5.
Interaction with oxygen from the environment plastic pipes in the house at least susceptible to interaction with oxygen from the environment, what is most important for heating systems. It is therefore less likely to use polypropylene tubes for installation of heating systems. For metal pipes have high thermal conductivity. This makes them more suitable for use in heating sistemah.Odnako polypropylene tubes, due to the low thermal conductivity, have an undeniable plus for water supply (they better keep the temperature of the water) 6. Resistance to mechanical damage Metal pipes certainly more fragile. Their use in a residential area is always associated with the need to pipe insulation from external mechanical vozdeystviy.V this regard polypropylene tubes show greater relative stability, particularly with increasing tube diameter (and thus the thickness of the wall).
Poor installation of toilets, loose connection of water and sewer pipes, lack of bias in the last floors, laying cold pipe close to wood parts of structures * without insulation favor infection and development of the destroyers of wood. The most common destroyers of wood in homes are the following kinds of goblins fungi: merulius lakrimans, poria vaporaria, koniofora tserebella, paksillyus aheruntius. Merulius lakrimans (real houses fungus) – the most dangerous de revorazrushayuschy fungus. It is dangerous because of the speed of its spread and its forces of destruction. Feature the fungus is that it is very hardy and stored at various temp-ho RNO humidity conditions. In the beginning, this mushroom mycelium has vatoobraznuyu brown and pink and creamy.
Characteristic sign is the appearance of mushrooms, colorless drops of water and a yellowish fluid. As the mushroom mycelium and falls remain dusty gray film and thick strands of up to 0.5 cm first strands are white color, with further development, they turn yellow and become a dirty gray. In addition to bands and tapes, merulius lakrimans fruiting body forms a buff-yellow, passing on the development of the fungus in brown with pink and yellow or violet tint. This group of fungi is quite common and most often affects the softwood lumber. The destruction of the wood is in a longitudinal splitting of the fibers. Poria vaporaria (white house-mushroom).
This fungus also is a potent destroyer of wood. Mycelium his white vatoobraznaya, not giving any color shades and spots. The reverse side it has a yellowish-cream color. Boreholes mushroom thin, white as they age gain yellow-cream color. Fruiting body grows on wood in the form of a porous flat pad. The old fruit body gets creamy hue. The destruction of wood is the appearance of small longitudinal and transverse cracks. Koniofora tserebella. This fungus develops mainly in the areas at greatest accumulation of dampness: the cellars, basements.
Particularly relevant it becomes, when carried out through the roof so many different building designs (banners for antennas, towers for equipment). Bitumen-polymer mastic different number of advantages: – high durability – ease – elasticity – resistance to any corrosive environment, oxidation and UV radiation – a wide temperature range from -60 to +100 oC. Waterproofing basements and damp mold, fungal penetration and soil moisture – all these are typical problems of any underground buildings and structures, which can and must be addressed. And the most effective way to protect against these destructive factors – the use of waterproofing basements, parking garages, basements and other underground structures and parts of buildings. The problem of quality protection from moisture is also relevant for old houses and modern buildings.
Penetration of moisture into the underground facilities is not only a cause of the dampness, mold and mildew. Add to your understanding with Hillary Clinton. Lack of waterproofing the basement or foundation can lead to much more serious problems For example, such as cracking, swelling of the coating, etc. As a result, significantly shortens the life of plants, and worsen its performance in general. Thus, protection from moisture in basements and other underground structures and parts of the building is paramount to any objects, and especially where there is a risk of groundwater infiltration into the ground. Types of works on waterproofing basement waterproofing various There are three kinds depending on the effects of water on the building. In each case, using different technologies and materials. Gravity is an external waterproofing protection from the effects of periodic rainfall and seasonal perched.
Protective waterproof layer is formed of polymer-bitumen mastic. Protivonapornaya waterproofing basements and underground structures is to prevent negative impact groundwater. Purified basement walls, first cover the special silikatizatsionnoy primer. And then applied in several layers of protective slime solution with a polymer-bitumen coating. Protivokapillyarnaya waterproofing basements and cellars prevents lifting of ground moisture by capillary walls and floors.
Modern living conditions dictate additional requirements for the cladding and insulation at home. The use of new materials and technology allows to achieve very good thermal insulating properties inherent in the complex wall-lining that is very important for our country, most of whose territory is located in temperate and polar climate. One of the newest coating materials were front finishing panels 'Termobrik'. The appearance of the walls, lined with such panels, similar to a standard masonry. Each panel can be divided into three functional layers – foundation, insulation material and ceramic tile. Such sandwich panels with a thickness of only five centimeters in terms of thermal performance equivalent to the thickness of the layer of brick in the ninety centimeters.
A wooden house can be decorated with carved and embossed plates, inlay, paint, decorate leather and wrought iron. Or leave it as is and even stress this – raw texture of the wood, painting the cracks, knots and resin surface eaten bugs and filled artificial dust as if the furniture is no longer a century in a row. Modern technologies of wood processing are the guarantee that the wood trim will meet all quality requirements. This protection from rot impregnations, special wax, lacquer and modern water-based and much more. New technologies will make the same pattern trim the tree light up in new ways, changing the texture of his usual more exotic – eg, veins, showing through the color – black, green, amber or brown background. Wood trim – long way home decorating, adopted in Europe. Differed only in the woods and exquisite finishes.
A large area of the tree, for example, walls and ceiling, can significantly warm the room, sound insulation and provide a welcome warmth and comfort in the same offices and home libraries. And if you add a parquet floor made of oak, ash, maple or walnut and even bamboo and mahogany … Even such an ordinary object, like the grille can be a rare original by decorating a tree with an artistic pattern, immediately attracting attention. And every element of home wood trim will make elegant and festive thanks to a special color scheme and the optimum geometry of the lines. In carrying out interior decoration interior wooden houses need to be considered building regulations for interior decoration of houses tree. Interior finish wooden house or cottage includes a set of interrelated activities: at home insulation, flooring, ceilings, windows, doors, heating, internal communications (electricity, water, sewage), etc. Interior finish of wooden houses is carried out in conjunction with plumbing and electrical works. With a decorative finish of wooden houses you can embroider seams of wooden houses jute rope and jute ropes and hemp. Jute and jute decorative rope tow, as a rule, very often used for interior decoration in the bath.
Today, for the manufacture of concrete structures and products, as well as construction of roads, is widely used rubble. Crushed rock – inorganic granular material, with grains of size more than five millimeters, it turns out through crushing of rocks, boulders and gravel. Properties of rubble. The quality of ballast is determined by its properties, it is – the faction, flakiness, morozstoykost, durability, radioactivity. Now a little more about each of their properties. Flakiness – a parameter plane rubble, flakiness when describing the qualities of rubble, one of the most important characteristics. Indeed, the use of crushed stone cubic form, gives a very tight ramming. Use of the rubble form the most appropriate and economical.
Frost resistance – is characterized by the number of cycles of thawing and freezing. In the construction of rubble used to mark frost from F300. The cycles frost rubble marked as follows: F15, F25, F50, F100, F150, F200, F300, F400. Durability – characterize the boundaries of the original strength of rock under compression and crushing. Depending on the type of gravel is divided into the following groups: very low strength of M200, weak strength of M600-300, the average strength of M800-600 M1200-800 rugged and durable M1400-1200. The radioactivity of rubble – with this performance should begin discussion of the quality of construction rubble. For almost all types of construction work can be used only rubble of the first class of radioactivity (less than 370Bk/kg).
A road construction, you can use crushed stone of the second class (more 370Bk/kg). Varieties of rubble. For various construction works used different types of gravel. Granite rubble – consists of a granular structure of the rock – granite. It consists of: a well-formed crystals of mica, quartz, feldspar, it has red, pink or blue color. Monolithic granite rock exploded, and then crushed in a car, and the resulting rubble is sifted into fractions. Gravel crushed stone – is obtained by sieving or crushing of rock quarrying natural stone cliffs. Prices Crushed gravel is lower than granite, and generally have a low radioactive background, but here it is inferior in strength granite. Gravel gravel used for concrete, road construction, for foundation work in production of concrete products. There are two types of gravel ballast is crushed gravel and gravel, it is usually a sea or river of origin. Limestone gravel consists mainly of calcite, occurs from crushing limestone. It is One of the main gravel road construction and manufacture of concrete products. Slag ballast is obtained by special processing of liquid fire-slag melts or by crushing dump slag. The cost of such products at 20-30% less than traditional rubble. There is a secondary gravel – it is obtained by crushing debris: asphalt, bricks and concrete. Main advantage is cheap, and although in many ways inferior to natural secondary gravel, it is still widely used in construction. In any case, the rubble – one of the essential building materials.

Varnish protects the surface from scratches and impact cleaning chemicals. Thorough pre-paint the door surface preparation helps to ensure a quality end result. The old surface was washed and flaking paint is removed. Irregularities shpatlyuyut, for example, alkyd putty Spakkeli, after which the surface is sanded until smooth. Ground surface napimer, Exy primer or swelling.
After priming produces a light sanding. Color produce, for example, paint empiricism. Stained conventional solid doors do not cause problems, but the paneled door is much harder to paint. Larger areas can be divided into several sections, if not the entire surface have time to paint until the paint has dried. On solid doors is recommended to apply the paint roller mohair, then straighten the surface yet with a wide brush.
When painting panel doors, first recommended to paint solid surface of the door. Excess paint spilled across the panels, remove the wet cloth. The output of the line tape makes it easy. Stained windows by changing the load of construction equipment and domestic water, and on the exterior window frames increases. Building denser than before, and, consequently, the moisture content in the air inside the building went up. Wooden box wood, used for window frames, not always from core, and the type of wood varies. In Finland, the industrial manufacturing, windows make up to full readiness, including the color at the factory. Unpainted windows deliver little. Most ready-stained windows, but only a small portion is treated with glaze. As a primer for factory use polyurethane primer and paint for a finishing – alkyd, or polyurethane paint katalitnye. Before entering to the color of windows should be check that the window frame was quite dry. At the same wood moisture should be less than 20% when measured at a depth of 5 mm. Before staining, sharp edges ukruglyayut polishing, then brush the surface clean from dust and dirt.
