Ceramic tile

What is the reason for this success shingles? First of all - the attractiveness and durability, during which the material retains its technical and aesthetic properties. Ceramic tile is securely protected from the weather - it can withstand more than 150 cycles of freezing and thawing. This material is resistant to external influences - acid rain, solar radiation, extreme temperatures, and also copes with the function of heat and sound insulation. Small size of individual elements to cover the roof of the most complex shapes without large amounts of prirezki material. Shingles provides optimal ventilation conditions subcritical velnogo space. Types of tiles ceramic tiles - this piece of plastic roofing material fusible clays by firing. It can be an S-shaped, undulating, high-and low-profile, bespazovoy (flat), and trough. Natural color of ceramic tile, depending on the composition of clay and firing modes are red-brown or yellow-gray shades. Over time, it is covered by a noble patina and slightly darker. And on the market today a variety of colors clay tiles is the result of engobing - drawing on a blank tile surface of a special solution - engobe. It is composed of powdered clay mixed with water and various minerals, which give by firing the appropriate palette. Glazed tile is good because over time it does not change its color. Another way to impart non-traditional colors - glazing. Before firing, the surface of workpiece shingles applied vitreous mass. Under high temperatures it solidifies, forming a protective layer.

Ventilated roof

As a rule, those who neglected to detail the project and decided to check his erudition on the construction of his house, waiting for the November surprise, associated with wide swings in air temperature near the zero mark. Roof tested the September and October rains incessant rains, the house is closed, the windows sealed, full swing, finishing work. Where you are getting wet, if the roof vented? The concept of "ventilated roof" implies the presence of three loops of ventilation: ventilation space between the coating and waterproofing, which covers all the planes, regardless of the complexity of roof ventilation space between insulation and waterproofing, which excludes the presence of stagnant zones; ventilation underlay space, which is part of the ventilation system at home. For decades, imperfect building materials and technologies allowed (or forced) to build the house, breathing through the wood, brick, cracks in masonry, cracks in windows and doors, gaps between layers of glassine or roofing material, in which randomly combined (or merged), all three required ventilation circuit. Payback for the seeming simplicity was, at best, drafts, higher heating costs, familiarity with glass wool and significant restrictions on the designer's fancy interior decoration. In the worst case, if the cracks were not enough, in the most unexpected places appeared damp. Special vents were held only in bathrooms and kitchens. Modern roofing materials are allowed to decide this question.

Functional plane

To get started is to define the notion of "flat roof". In this case, the flat does not mean smooth. The design of this type requires a slope (slope) ranged from 2 to 12 °. If this figure is higher, the roof is called the slope. Deviations necessary to provide for rapid removal of moisture from the surface of the roof membrane. Depending on the design and type of materials used and exploited distinguish nonequivalent spluatiruemye roof. The first of these are not designed for constant load (displacement, the installation of any "weighty" equipment). The latter are designed for heavy use and are resistant to any mechanical stress. In turn, operated by a roof divided into several types of functional purpose. So, it can be covered with limited use (gravel backfill), coverage for intensive use (or ceramic paving tiles, granite, etc.), as well greened roof placed on it with the greenhouses, greenhouses, flower beds or lined with grassy carpet on the perimeter. Usually operated in the regeneration of the roof use a combination of options, such as beds and playground for recreation. Operated by a roof could be attic and bescherdachnymi (combined). When the attic version (with heat-insulated podkrovel-nym floor) insulation, waterproofing and protective layers stacked on the floor slab above the attic. The advantage in this case is the ability to monitor the status of surface and drainage systems (for a landscaped roof). As exploited and neeksplu-atiruemye roof can have two basic designs, the main difference lies in the location where heat-insulating material.

Roofing membrane

Andrei Ivanov domestic technical literature to highlight three types of soft roofs, which differ in composition of waterproofing coatings: bitumen-polymer or roll roofing, mastic roofing and membrane roofing. Sometimes there are texts where the membrane is called bitumen-polymer materials. To the prevailing standards of Russian technical texts is wrong, and the error caused by the fact that English's technical literature, the term membrane called all types of roll roofing materials, including bitumen-polymer. In Russia, however a widespread membrane roofs have only recently, so the total proportion of membrane roofs in this country among all types of soft roofing does not exceed one-half percent. Slightly more than two percent today make roofing mastic, and the rest fall on asphalt roll roofing. For comparison, in western Europe, the proportion of membrane roof reaches eighty-seven per cent. In most cases the roofing membrane used to cover roofs with low slopes, the so-called flat roofs. Flat roofs are usually lighter than pitched, and as cheaply as in the device, and in operation. Operated flat roof provides extra space on the roof of the building, which can be used in summer for recreation and sport activities. Lately it has become fashionable to cover the roof of a carpet of vegetation, creating a so-called green roofs. In the latter case, the roofing membrane based synthetic rubber or thermoplastic olefin virtually irreplaceable. Proportion of membrane roofing in domestic urban development is growing fast enough.

Roof construction of pressure-treated wood

Use the space under the roof of the house provides additional living space, at relatively little cost. This problem is solved with the implementation of the mandatory conditions and special requirements for the construction of a mansard roof during its construction: the requirements for thermal, hydro, wind and parozaschite roof. Roof with a wooden crate, a device which is often practiced by American, Canadian and Scandinavian civil engineering firms, is one of the best options that satisfy all these requirements. Roof with a wooden frame and crate have other advantages. They correspond to the climatic conditions of northern regions, can be easily and quickly assembled by hand, and fully comply with environmental requirements. Of all the wooden structures of the roof the best option is the option of integrated bystrosbornyh systems. Bystrosbornye of sloping roofs with wooden frames include many different elements. Bearing the function of the skeleton, whose type is determined depending on the requirements for a particular roof. In any case, it is a truss-girder construction. As the base under the roof, performing carrier function and features windscreen, used slabs of compressed wood. Between the rafters of roof frame fits a continuous layer of insulation directly adjacent to the plates of the board. On the underside of the insulation layer vapor barrier closes the film. This is followed by an internal wooden crate, which carries the plasterboard or other material for finishing interior attic.

Termoplastkompozitnaya shingles

Is it easy to choose the ideal coating for the roof of your holiday home? Slate is no different aesthetic, metal sheets do not provide adequate insulation, roofing felt at all "to-face only outbuildings. Optimal choice is likely to be called shingles, but not simple, and termoplastkompozitnuyu! Classic tile has a number of disadvantages, among which are the large mass, complexity of installation and relatively high costs. In addition, it is extremely brittle material: moisture accumulated in the pores, literally tearing the shingles in the cold. Termoplastkompozitnaya tile is an adequate alternative and has many positive attributes: strength, lightness and ease of use. Termoplastkompozit - a chemically resistant construction material made of silica sand and polymers with the addition of dyes. Pigments give the substance of additional aesthetic properties, and the presence of special additives guarantees protection from ultraviolet radiation and combustion. Main technical characteristics and properties: 1. Ease Termoplastkompozit from which the similar tiles in 1.7 times lighter than ceramic, and in 2,4 times - concrete. This property is important both for transport and installation. 2. Water resistance coefficient of water absorption in termoplastkompozita 2-3 times lower than that of concrete and clay tiles. 3. Easy to install Such tiles can be nailed to the roof with nails. It is easily cut and quickly assembled. In this temoplastkeramzit can be placed even on the slope of 15 degrees instead of the traditional 25.

Technoelast - a review of properties and brands

The roof of a building should be water resistant and water resistant, cold-and heat-resistant and durable to withstand snow and wind loads and mechanical stress while cleaning snow from the roof, and during the repair. The technology of roofing work, and their complexity depends mainly on the materials used. They can be rolled, mastic, foil and piece. The easiest way (and cheaper) to cover the roof of a flexible roll roofing. True, traditional roofing and roofing are not very durable and require repair after a couple of years. The latest technologies allow a flexible sheet flooring easy installation and at the same time very robust. One of these roofing materials is Technoelast. Due to the use of a synthetic polymer (polyester) or glass (fiberglass), Technoelast provides unparalleled strength and elasticity. Its basis is impregnated with a mixture of unoxidized asphalt, modifications of synthetic rubber and mineral filler. There are several brands Technoelast (Table 1). Marc material weight 1m2, KG Type foundation type of surface coverage, up / down method of laying Roll Size (length width), m EKV6, 0 "Vent" 6.0 Polyester, no less than 250 g / m * Thick broadcast with / "vented" cover fusing / fixing 7,5 x1, 0 EX 5,0 5,0 Polyester, not less than 170 g/m2 Thick broadcast with / self-adhesive Self-adhesive coating (cold gluing) 10x1, EKP5 0, 0 5.0 Polyester, not less than 170 g/m2 broadcast with coarse / film fusing 10x1, 0 TKP5.0 5.0 Polyester, not less than 200g/m2 Thick broadcast with / film fusing 10x1, EPP4 0, 0 4.0 Polyester, not less than 170 g/m2 film / film fusing / fixing 10x1 , 0 HPPZ, 0 3.0 Fiberglass, not less than 60 g/m2 film / film fusing 15x1, 0 In the manufacturing process Technoelast formed elastic polymer-bitumen composition to withstand wide temperature range and resistant to cyclic deformation during many years of operation ( Table 2.).

Open light

Vladimir Mikhailov live a stone wall and a solid roof - well. The only pity is that stone walls do not allow natural light and live in artificial in nature is not very desirable. Output may become translucent structures, which are increasingly being used in country-house. The abundance of light in the house always creates a festive atmosphere and the mood. However, of the earlier technical capabilities are not always allowed, on the one hand, to create this very abundance, on the other - to provide protection from the cold. Often had to choose on the principle "either - or, as in our harsh climate and the choice of something, usually do not: the main north - it's warm. That's where the thick walls and small windows in which even on a sunny summer day in the rooms of gloom. Under the conditions of country life, of course, have preferred to spend time in the open and glazed verandas, where light enough, but this is only in the summer. A light like as time in the winter when the sun comes up after breakfast and after lunch already setting. Fortunately, new technologies have given us many different translucent structures that allowed, first, just to fill in natural light, country houses, and secondly, to give the buildings an unusual appearance. The first mention of the winter gardens, which are not just writing our magazine. Thanks to modern developments now have the opportunity osteklyat large amounts, effectively retaining the heat. If equipped with the proper heating system, then if desired, and a pool to do and study and conservatory.

Under the roof of the house

Konstantin Borovno Under the roof of your holiday home will be warm and fuzzy, if it is protected from the adverse effects of moisture. From precipitation and steam coming from the interior, save the waterproofing! The market today is so rich in all kinds of waterproofing materials that tell about all the impossible. Therefore, we consider only the basic ones. Membrane If you decide to cover a roof metal tile or natural tiles, then without a waterproofing layer is necessary. Materials such as asphalt and roofing felt, - a relic of the past era of No Return. Use them uneconomical. Cost, of course, relatively low, but then the torment is spent on maintenance and repairs. That's what the proverb "miser pays twice: The first decent contemporary material - Breathable underlay membrane, they are also called" breathable ". Superdiffuzionnye membrane. Vlagoizolyatsionnye these materials are very important for the device of the roof property: water vapor pass through them, and the water itself is not. Moreover, their water vapor permeability is so high (not without reason the super-prefix) that these membranes can be installed close to a heater, without the lower ventilation gap. Superdiffuzionnye membranes should not be applied to roofing materials, the flip side of which is not designed for frequent or prolonged contact with moisture. That is not suitable metal and corrugated bitumen sheets - evroshifer. But no problem, these membranes are used in ceramic and cement-sand tiles.

On systems of drainage

Sewer systems are needed virtually any roof. They protect the outer walls and basement from water, the foundation - from excessive moisture. Thanks drains water from the roof is collected and sent to one place, and the building is not threatened premature failure. In addition, the system can be as decorative, to emphasize the transition from the roof to the walls of the gable to the front. This house will look stylish and elegant. The most common materials for gutters - PVC, galvanized iron and copper. System of PVC each year are enjoying increasing popularity. Their undoubted advantages are: - complete absence of corrosion - almost complete silence in the rain - resistance to natural influences, including UV rays - frost resistance - resistance to chemical attack (acids, hydrocarbons). The disadvantages are: - to change the linear dimensions of the sudden temperature drop - to combustion instability (at the same time, plastic is difficult to ignite and stops to melt immediately after the removal of fire) - smaller than that of metal, resistance to mechanical stress. The service life of plastic guttering is about 50 years and depends largely on the installation and the environment. System made of galvanized iron are less durable than PVC. Without the special coating after 6-8 years of zinc layer is destroyed and the iron starts to corrode, reducing the life of drainage and spoils the appearance of the building. To avoid this, the system is covered with enamel or lacquer on metal, designed to work outdoors.
