Big country - large volumes of housing construction. Not only a multi-storey, but also private. Each developer is important and necessary knowledge of general construction issues, according to standards and rules, including about roofing processes.
Competently performed roofing structures - this is the key to not only warm house and a comfortable atmosphere, but also the durability of other structural elements.
The roofing device is an important stage of building buildings.
In the heated house, the temperature differences are inevitable, the presence of moisture in the air in the form of steam, condensate. The pairs are produced by the vital activity of man or animals, penetrates construction structures, cooled and moisturizes them. Overwhelming majority building materials paste air to one degree or another. Therefore, any residential building, individual or apartment, is an air volume in which warm air rises through all designs up.
In high multi-storey houses The effect of thrust appears. Warm air rises to the upper floors, it is especially noticeable in the entrances, and penetrates out through windows and attic. On the lower floors, on the contrary, there is an influx of outdoor cold air. This process occurs in a single-storey heated house, only with less dynamics.
On the other hand, heat-air pairs are condensed in structures into water, which not only moisturizes them, but also has the ability to drain down, filling the cavities in structures. The main function on the condensation of the water vapor takes on the upper part of the building - the roof. In winter, this process goes intensively and constantly, and in the summer mostly at cool night.
The most modern I. effective method Prevent or significantly reduce moisture condense in the roof - make it ventilated naturally or forcibly. Natural cold ventilation It will not require energy costs, so its design is preferable. However, there are roofs of complex architecture, which lacks the strength of natural ventilation, then forced comes to the rescue.
Ventilation takes warm wet air into the surrounding space, thereby leaving bearing structures, insulation dry, extended service life and providing heat insulation. We need to control this process, which is carried out using the so-called roofing cake.
The concept appeared relatively recently and denotes a multilayer structure of the roof, in which the leading place is assigned to the creation of ventilation channels. There are two types of roofing pie: for heated and insulated rooms and for cold roof. Each layer is interrelated functionally with other layers, and the absence of any reduces the protective properties of the entire cake.
If the attic is a cold, displeased part of the building, is performed in several consecutive layers. The following tools will be required for work.
From the top of the rafter, laying the waterproofing film (not to be confused with vapor barrier). Prisis film should be 20-40 mm for condensate removal. Fix it along the rafter by a counterclaim with a thickness of 30-50 mm and the width in the thickness of the rafted themselves. Film in the place of attachment is better glued to double-sided adhesion.
To reduce waste, the film can be placed with horizontal rows from the bottom up and with the allen at 100-150 mm. Connection locations are punctured by creating a solid cloth. The water generated from condensate will be flipped over the film to the roof eaves.
After the device of the waterproofing layer on the counterclaim they are scattered across the rafted crate for roofing. The width of the board, the gap between them is chosen depending on the roofing material.
At the end, the roofing material is placed directly to the crate or construction stove. It is fastened with special nails, self-drawing or clemas for the crate. The places of fastening of the roof are protected by sealants, and the shapper is pre-treated with an antiseptic. Additionally, it is possible to perform a rough binder on the rafters on the side of the attic.
Between the roof and the ventilation gap appeared in the total thickness of the crate and the counterclaim. This is 55-80 mm height of the underground space along the tilt of the rafted. In winter, a warmer attic air, partially penetrating through the waterproofing, will rise to the skin of the roof and output into the atmosphere, without having time to condense moisture. And in summer, the air heated air is also excreted from under the roof.
Important for the underpants is the valuation of the attic. It is carried out through hearing windows, arranged on the fronts from different sides. Ventilation of the residential premises, the attic and underpants are interrelated, and one of their goals is to reduce steam and condensate in roofing pie.
Often the attic room is used as an attic, hesitated from the roof side. In this case, several layers are added to the roofing pie. Now there is no attic air interlayer between the residential premises and the roof. The warm and wet air of the attic immediately penetrates the underpants space. And if you do not accept additional measures to assign it, condensate will be much larger and the design will start wet. The thermal insulation materials will stop performing their functions and the air indoors will be cold. We have to strengthen heating.
In addition to those layers, which are already performed in a cold roof, add a thick layer of insulation, stacked between the rafted from the inside. If conventional rafters are 150 mm wide, then the thickness of the insulation between the rafter can be no more than 100 mm. The reason is the need to leave the minimum clearance (not concerned) to provision of waterproofing, which reaches 40 mm. If there is a touch, water flowing on isolation will fall into the insulation. To increase the thickness of the layer on the rafter, the timing of the desired thickness is selected and the insulation is added.
Then it is closed with a vapor barrier film. The goal is to maximize the dropout of the pair from the room in the insulation so that it does not have its wet. The wet insulation is not good anywhere, it does not hold warm and in addition moisturizes the surrounding structures. The vaporizolation is cooked first black, and then the finite cladding.
Now the path of wet steam to the roof is now blocking, and although it still penetrates it, it is put into the atmosphere under the underfloor ventilation flow, not harming the roof structures. And if the warm room itself is not ventilated, where will steam leave? Through all sorts of microscopic pores and cracks, it will still go up to the roof. This will contribute to this overpressure, sampled in the warm place of the attic.
Remove excessive pressure, reduce moisture content in a residential room and thereby help underwear ventilation to output wet air into the atmosphere will allow ventilation of the room itself.
Longitudinal ventilation channels of roofing pie will not work effectively if, on the one hand, at the bottom, in the eaves itself, not to ensure the inflow of atmospheric air. On the other hand, it is necessary to give the exit of the moistened air from the upper part of the roof - from the skate.
The waterproofing film is the most durable of all types of films used in the construction of the house, so it does not let water or moisture even under high pressure.
The waterproofing film is displayed and glued with a sealant to a metal cornisic bar installed in the plane of the crate. The roof is fixed on top. Air flow is carried out 3 ways. Firstly, through the gaps of the roofing material profile, secondly, through the frontal sinks and, thirdly, through the micropores of the waterproofing film, pulling the pairs from the insulation.
When covering the cornice in its lower part is provided ventilation holes or gaps depending on the set of design options of the cornice. One of modern methods - This is a solid binder cornice plastic panels With perforation for roof ventilation.
Depending on the roofing design, the air flow from under the roof is assembled in a skate and is removed into the atmosphere either through structural gaps along the length of the skate, or through the frontal holes. For example, in a set of ceramic and metal tiles, special elements of the skate with ventilation gaps are provided. Additionally there are challenges for non-standard skate shape.
it exterior Roof. The inner device is performed in a certain sequence.
Roof ventilation is not an independent process. On the contrary, ventilation or its absence in the premises directly affects the air exchange in the roof. In order to effectively remove the destroying moisture from the residential premises through the roof, it is necessary to consider the ventilation of all elements of the building as a single process.
If the roof shape is complicated, has many transitions, endands, ventilation processes must be divided into areas and form air flows in the roof separately. As a result of effective ventilation, the air in the underpants should be replaced within an hour about 2 times.
The effectiveness of the ventilated roof depends on the tilt of the skates. What they are cooler, the stronger the ventilation process occurs. And, on the contrary, in the roofs with a slope less than 20%, the underpants ventilation is unstable, effective only under wind pressure.
It is always a useful device on the roof of additional exhaust elements (aerators), helping to enhance the natural ventilation of the roof. They should be positioned on the roof of a complex shape, when ordinary means is no longer enough. Aeriates are installed near the skate.
The thermal insulation properties of the insulation and the durability of the roof structures are directly dependent on the presence of moisture in them. Therefore, the ventilated roof and the design of the ventilation of the premises is economically beneficial even when it is necessary to establish a forced air exchange.
Good day, dear friend!
And it is not surprising, because the guests of our site are our friends. And friends understand each other with a half-clow ...
So, you are here, which means that your home, apartment, an industrial or public building, a livestock farm, a warehouse or pipeline needs effective thermal insulation. And we just have what you suggest are polyurethane.
And this is not a loud word in the field thermal insulation materials, and N. best insulation. it insulation that really works And saves your money.
The company "SHOPFIMENSION", working for more than 9 years in Moscow and the Moscow region in the field of insulation of walls, facades, loggias, roofs, floors, floors, foundations, refrigeration chambers, pipelines, etc., managed in this question, as they say, dog eat, therefore, with full responsibility, it can declare that
more multifunctional, reliable, efficient, durable and even eco-friendly heat insulation today does not exist!
And this is a logical explanation.
The effectiveness of the PPU is its low thermal conductivity and a closed porous structure that does not miss any couples nor moisture. It follows that PPU insulation performs the function not only insulation, but also steam, waterproofing, and can also maintain its qualities for 25 to 30 years.
Polyurethane foam is applied by sprayingSo, it can repeat the form of any even complex surface and completely eliminates the presence of cold bridges in your thermal insulation.
Its adhesion to any surface is so high that there are no restrictions for the use of sprayed PPU.
Chemical and at the same time biological resistance of polyurethane foam makes it the only one among insulation, which withstands the impact of aggressive media, bacteria and representatives of the Fauna world over the years.
Among other things, the sprayed PPU can also be used as sound insulation of walls and overlaps.
And the most important point is its chemical neutrality. Polyurethane foam is environmentally friendly. What explains its widespread use in the food industry, in animal breeding, when insulating the poultry farm, as well as as thermal insulation refrigeration equipment, vegetable stores and warehouses. Confirmation of this fact are numerous tests and sanitary certificates.
The list of benefits of polyurethane foam polyurethane foam can be continued, but each word must be confirmed by the case. COMPANY "SHOPFFESOLITY"

Let's create heat together!
First of all, it is necessary to be able to correctly select the material for roofing, hydro and thermal insulation. To date, the market is filled with high-quality insulating insulation for roofs with excellent operational properties.
Choosing material for insulation, you must pay attention to the following points:
In addition to the listed, the roof configuration is also of great importance.
Distinguish the following types of roofs:
Particularly popular materials for insulation are plates from minerals, foam concrete, polystyrene foam and fiberglass plates, polyurethane foam, foamed glass.
Each of the insulation differs from others by environmentally friendly, thermal conductivity, water absorption, vapor permeability, strength. Differences also relate to prices.
One of the most sought-after materials is mined. Its popularity is explained by low thermal conductivity and the ability to withstand high temperatures.
Mineral wool can be made on the basis of different materials.
The following types of this material are distinguished:
In essence, Teplokarovl is a special format of the roof with a layer of insulation, which is perfectly holding moisture.
Mineral wool The first two species is a rather good choice. But it should be remembered that the moisture-absorbing properties of fiberglass are not very high.
In addition, the use of wool implies additional costs for the installation of vapor and waterproofing protection both from the inside and outside.
Styrofoam It is cellular (foamed) plastic masses. The density of this material is significantly lower than the density of the polymer (source raw material), since the main part of its volume is occupied by gas.
This causes the highly high sound and thermal insulation properties of this material. The thermal insulation qualities of foam plastic are quite high, provided that the temperature of operation of a particular type of material is not higher than the temperature of its destruction and the loss of the structure (destructation temperature).
It also includes non-toxicity. Separate species (polystyrene foam) are allowed even for contact with food. The ease of foam makes it very convenient for use in construction.
Among the disadvantages of the material, the following can be noted:
In the photo The roof insulation scheme is polystyrene: 1 - plasterboard; 2 - rafters; 3 - extruded polystyrene foam; 4 - doom; 5 - waterproofing.
Polystyrene foam plates Also are an excellent choice as a material for insulation. One of their main advantages is the prevention of the formation of so-called cold bridges (because of which heat leakage).This is achieved through a special step or spike-groove compounds. Material has very high moisture-resistant properties. Its application allows not to install additional defense From snow and rain.
In addition, polystyrene foam is distinguished by high strength and bearing capacity. At the end of the installation of insulating materials, you can get a holistic design, perfectly withstanding high temperatures and voltage.
Nowadays, extruded expanded polystyrene foam is often used. This material is almost universal and combined with any types of work.
The price of insulating materials depends on their qualitative characteristics, density, size, thickness.
For example, a foam leaf is 100x100 cm in size, the density of which is 25, the thickness is 40 mm, costs 80 rubles; With a thickness of 50 mm, the price is 100 rubles; And if the thickness of the sheet is 100 mm, then the cost increases to 200 rubles.
In recent years, another insulation becomes popular - faith. Thanks to the special manufacturing technology, the structure of fiberglass contains air, which causes its extremely low thermal conductivity.
One of the most important qualities glasswater - Durability (service life can be 50 or more). Another advantage is that it is practically not lit and provides high countertileness.
Together with insulation, materials for waterproofing are used, the purpose of which is to protect against moisture. The most sought-after materials today are polyurethane, mastic, rubberoid, etc.
Do you know what? All about its proper device and installation.
How to mount slinge system four scope roof Described in this. There you will find a detailed video on this topic.
The choice of a particular insulation is due to the roof configuration.
The insulation of the usual scope roof will cost not as expensive as the warming of a four-page.
Speaking of the advantages of thermocrust, it should be noted the excellent sound and thermal insulation and the protection of the main coating from damage. It affects the technique of conducting mounting work.
There are some important momentsThat you need to go through the start of work on the insulation of the roof:
The process of insulation of the roof involves the choice of insulating materials.
The main ones are:
Since the films are unilateral, when using them, it is necessary to pay attention to which side they fit. Otherwise you can achieve the opposite effect.
Although at first glance, the insulation seems to be easily implemented by the process, but with independent execution of work, some errors are possible.
Most often it concerns the wrong choice of material, its width. The insufficient width of the insulation becomes the cause of the formation of slots and the low efficiency of the building of the building.
Another error is the use of a wet material, which leads to the formation of rust on metal elements, rotting the structure of bulkhead, rafters and appearance in the underpants unpleasant odor.
With a high humidity of the insulation, it is impossible to avoid water penetration inside the house.
The next error concerns the lack of hydro and vaporizolation. The layer of heat-insulating material must certainly be protected from clusters water and moisture.
Therefore, moisture insulation materials will be needed for a layer of thermal insulation outside and protecting the undercase. From the side of the residential area, protection against water vapor exposure is created using vapor barrier.
The ideal choice for the pitched roof is slab or rolled materials. They are laid between the rafters, to the crate.
In the process of isolation, it is necessary to take care of the protection of the material for insulation from below (with the help of a vapor barrier film) and from above (by applying the sealing tape). Between the roof coating and insulation should be sagored.
In addition to laying the heat-insulating material between the rafters, it is possible to use in a different way: to lay them on rafters. With correct performance, it is possible to ensure not only heat - but also noise insulation of the building.
The insulation of the pitched roof, under which the presence of a residential premises is assumed, has its own characteristics. With high humidity in the attic, it is recommended to use reinforced films, on one side of which foil is applied.
Special attention must be paid to the ceiling closure sites and external walls. In these places, the insulation must be tightly adjacent to the walls.
If there are cornices, you need to take care of their insulation to prevent cold air from entering the undercase.
In complex areas to attach the film, a building stapler is used, which greatly facilitates the whole process. You can also use wooden slats.
Attic more than other premises need insulation, since it is not protected from the cold from the outside. In addition, it has large square interaction with the external environment.
Under the overestimated requirements for thermal insulation, the quality of thermal insulation materials also rises. The most demanded material for the insulation of the attic is mineral wool.
From the insulated side of the insulation, the steam insulating layer is placed, on the other - waterproofing. It is also necessary to provide space for ventilation in order to remove excess moisture and air ventilation.
Given the requirements for the quality of heat resistant, when creating insulation of the roof of the attic, it is advisable to use tile or slate as roofing material. Metal is better not to choose.
In the regions with a very cold climate, you must take care of the warming of the garage. Most often used glass gambler, which is produced in rolls.
The width of the material in them for convenience corresponds to the rapid step. Glasswater has sufficient density, which is another plus.
If the bars are so wide that there may be 50-millimeter holes between the insulation layer and the waterproofing material, then the glass gamble can be fixed between the rafters.
In case of insufficient thickness, the insulation is attached over the established frost. The final thickness of the layer of heat-insulating material will be 10 mm.
On top of the glass gambles, a parobararier must be installed to protect the garage room from steam. Top of pinching special bars and put the facing. As a facing it is possible to use dry plaster, lining, drywall or other material.
The price of roof insulation can fluctuate depending on the material, its thickness, the type of roof.

If you only built your home - it is recommended to pay special attention to the roof insulation process. It is very important in order for living in the house to be comfortable and cozy. After all, roofing functions are very important for the whole house. The roof protects against natural cataclysms, such as snow, rain, wind, dust layers. In addition, the roof creates the aesthetic perception of the entire structure, there can be a variety of design sizes. But if you choose between a reliable roof and - then definitely the choice will fall for the first option. Because the main task of the roof is the protection of the house. In the summer, the roof protects the house from overheating, and in the cold winter time - from the ice gusts of the wind and the wall. Under these conditions, it is very important to carry out the insulation of the roof outside and from the inside.
This, firstly, simplifies the task. And, secondly, otherwise there is a risk of incorrect installation. However, these are only theoretical reflections that must be performed before.
In practice, things are somewhat different. So, the process can affect the process. The fact is that stropile design And the insulation must be left open for some time for drying - and if it rains, they are inevitable their wet. This will lead to a loss of the insulation of its properties, and the wooden design of your home will begin to rot.
In this case, there will be a significant damage of thermal insulation. Under these conditions, the insulation of the roof of the private house is made from the inside after the installation of the roof is completed.
For competent, the roof insulation should consider certain rules and nuances.
This will be discussed in our article.
The insulation of the pitched roof implies the choice of material. We advise you to give preference to the insulation that can not lose their initial qualities for a long time.
In other words, it is irrational to choose the insulation of only 1-2 years.
The important quality of the insulation is to preserve its thermal insulation properties, water resistance, environmental friendliness, etc.
Therefore, the insulation of Mauerlat and others roofing structures It should be done using exclusively quality materials.
If you choose the insulation in terms of thermal conductivity, then consider what it is lower - the better. Today, the market of building materials literally pested with thermal conductivity with thermal conductivity of the category 0.04 W / m ° C.
In other words, the selection of the insulation does not take a lot of effort in search of the desired option.
As for the mass of insulation, they can differ significantly among themselves. It depends on both the manufacturer of materials and the characteristics of the insulation properties. For example, if the mass of one cubic meter of the insulation can be 11 kilograms, then the mass of other material can reach all 350.
Tip: Note that the insulation of the roof frame house Volumeful material can lead to weighting of the roof.
Under these conditions, the design of the roof and the rafter system must take into account the additional load of the insulation system to the roof of the house. Insulation single Roof A heavier material can differ significantly from similar installation of light insulation.
It should be noted the positive quality of heavy materials. They are tough in their structure and easily withstand a large weight of the roof. In addition, in the cold season, the snow formed on the roof will not be an interference for the roofing system.
But lightweight materials cannot boast of such quality, due to its softness. Therefore, they are not always able to withstand even a small burden of snow.
To determine the quality of the material, several factors should be taken into account. About them and talk in the final part of our article.
If you have any questions, it is recommended to refer to photo and video materials. They will tell in detail how to insulate the roof of the PPU. If you feel that the insulation of the roof of the house with your own hands you are not on the shoulder, then be sure to trust the work of work by professionals. Thanks to this, you will save and your time, and in the shortest possible time you will receive the result - as a warmed roof.
The insulation of the roof from the inside is produced not only to arrange in an attic room An extra room, but also for maximum heat conservation throughout the house.
If the structure has mansard roof, The insulation is carried out directly the roof itself, which is for the future room not only the roof, but also with the walls. If the design or has one slope, then most often the thermal insulation is arranged in the attic overlap.
The third option of developing measures is used in regions with a harsh climate, where they are insulated and the roof itself from the inside, and the ceiling overlap.
The modern building materials market offers quite a lot. types of insulation, of which You can choose suitable for any thermal insulation work.
All these materials are sufficiently light, so they do not lose the roof design and the whole house, but will make it much warmer. Technology installation of thermal insulation materials differ from each other, so it is worth considering some of them.
It should be noted that with the advent of auxiliary materials that facilitate the work process and are aimed at protecting the thermal insulation from external influences and the preservation of their operational qualities, it became easier to carry out the installation process.
Mineral wool
One of these materials is a vapor barrier film. It is designed to protect wooden structures and insulation from the effects of steams arising from temperature drops and leading to the formation of condensate. Excessive moisture provokes the appearance of a mold fungus, which destroys the structure of the tree, reduces the thermal insulation characteristics of the insulation and contributes to the appearance of an unpleasant odor in the room.
A vapor barrier membrane is fixed to the design of the roof or overlap before laying insulation materials.
When using a pair-protective film in a heated room, it is placed only under the finishing layer of walls.
To protect the structures on which there are high temperatures on one side, and on the other - low, vaporizolation must be located on both sides. Such structures include wooden attic floors and roofing when it is insulation. Concrete plates Do not require laying of vapor insulation materials.
Protective film may have different thickness and be different species - ordinary out nonwoven material or foil membrane. In the case of using the latter on the design of the attic overlap, it is filling the foil down, as it reflects the heat-rising from the bottom to the ceiling, thereby not letting it go out. Between themselves, the sheets of the material are fastened with a foil scotch, which helps to create a tightness of the coating.
Insulating films
Any insulation events are best carried out in the process of building a house, but, unfortunately, it is very often done only when you feel the winter cold.
Before falling down or laying the insulation, you need to spend preparatory work. This is especially important if the grainzit of the shallow fraction is used, the sawdust slag.
- Boards, fixed to the beams of overlapping, thoroughly laughed with a solution of clay or lime having an average consistency in thickness. These natural materials Create good overlap tightness, but at the same time - allow you to "breathe" the entire design.
- After complete drying of clay or lime, insulating work was made. Previously, it was mainly used slag, sawdust, dry leaves or a mixture of these materials. They fell asleep between the beams on the prepared boards.
It should be noted that old traditional method - It is quite reliable, and therefore some builders even prefer it to modern and to this day.
The film will be an additional obstacle on the way out of the premises of the heat house through the ceiling, as the heated air, rising up, not finding the exit, will fall and stay inside the house.
Sometimes vaporizolation can be fixed and inside the room to the wooden ceiling, but in this case it will need to be separated, for example, plasterboard plates. They level the ceiling and become another additional insulating layer.
When insulation of the roof rods, as well as when the overlapping is insulated, apply mineral wool and expanded polystyrene but mineral wool In this case, it is preferable because it has practically zero flammable.
If still it is decided to use foam plastic, it is recommended to purchase an extruded version. Although it has a slightly higher thermal conductivity, but it is not a fuel, and this is very important for wooden structures.
For insulation, roofing rods use different systemsBut they necessarily contain a layer of vapor barrier material, insulation, waterproofing and a counterclaim.
1. This diagram shows one of the variants of the insulation "cake". It is used when building a roof and roofing flooring.
After that, you can move to insulation measures, which are conducted from the inside, that is, from the indoors of the attic.
Final stage - decorative finish Cit plants 2. Another option may be a thicker insulating "pie", which also stacked immediately when the roof device.
If the roof is insulated in the already constructed house, where the roofing coating is fixed, then vaporizolation is fixed to the rafters on the side of the attic brackets, and only after that the insulation is stacked. Next, the process goes the same as in previous versions.
The insulation of polyurethane foam passes otherwise than bulk materials or mats of mineral wool and foam.
This method of thermal insulation has recently become increasingly popular and is suitable for both ordinary attics and attic, which will later become an extra room.
If the attic is ventilated, and the residential premises will not be arranged, then only the attic overlap is insulated. For this board and the beams are recommended to moisten for better adhesion, and polyurethane foam is sprayed on the wet surface between the beams. After foaming it, increase in volume and frozen, if necessary, another layer is applied. Such insulation will be quite enough to preserve heat in the house, as the foam penetrates all the cracks and hermetically closed them.
If the attic allows you to arrange a room on it on it, or the attic is an attic superstructure to the house, except for the overlap of polyurethane foam, roofs are insulated.
Spraying starts from the bottom of the structure, gradually climbing to the skate. A foam is sprayed between the rafters, and its lower layers, lifting and frozen, will be supported for the following upper levels.
A similar or attic creates a completely sealed uninterrupted space. Polyurethane foam will be well delayed heat inside the premises in winter and will not allow the attic to overheat in hot summer days. However, ventilation is still worth it, since the room must necessarily get air flow.
This type of thermal insulation has the following advantages over other insulation:
The following factors should be attributed to the "minuses" of sprayed insulation:
Not frozen polyurethane foam - enough toxic, so all work is carried out with mandatory leather protection, eyes and respiratory organs
Warming attic and roofs are necessary for buildings in most Russian regions, therefore it should not be postponed this process "for later", and it is necessary to carry out thermal insulation work at the stage of building at home. Excluding the method of spraying polyurethane, all other insulation measures can be carried out independently, observing the technology of work. If you enlist the help of a comrade, then the insulation of the roof can be performed in a few days.
