Most people agree that in a private housea large proportion of heat loss occurs through the roof. Quite often, the rising warm air passes through the roof because of lack of good-quality insulation. However, spending duly insulated attic You can eliminate such troubles, and rid yourself of the cold air flow from the ceiling in the winter season.
Earlier on insulation in the attichome, as a rule, do not worry too much. And it was not that in the old days, no construction was carried out qualitatively, on the contrary, these houses are many decades. In addition, they have always been warm, as previously relied largely on natural insulation - air, namely the one that accumulates between the floor and the attic roof slope.
The design provided for pitched roofsdetention in the winter snow layer, which is naturally closed the gap through which the cold air could get access to the room. Since the slopes of the roof is not insulated from the inside, it did not cause the melting of the snow layer, and thermoregulation in the premises was carried out by means of skylights. Such a method is still relevant in modern construction.
Moisture-temperature regime cold attic should have a record of 4? C higher than the average outdoor air temperature. That is really cold attic room is unheated.
The design includes a cold atticfrom the air outlet vents directly to the atmosphere. To reduce the number of intersections of the roof sections with insulation roll, taking the union sections of the channel by means of ventilation ducts. Such a device natural ventilation provides an excellent opportunity to maintain inside the attic optimal humidity and temperature. In such circumstances, it prevents the formation of condensation and frost on the inside of the roof.
Violation of humid-temperature conditionsIt leads to a significant moisture and heat insulation structures, and, consequently, to a loss of strength and insulating properties, disruption of the roof support structure until its collapse.
The roof of the building with a cold attic inUnlike warm attic is allowed to settle into life in any number of storeys homes. Insulation in this case is made for attic floors, and its thickness is determined in accordance with the climatic conditions in which the building is erected.
Thermal insulation of attic floor in two ways according to the principle:
with profile ceiling, in which the material is laid on top;
suspended ceiling - when insulation suit on the inside of the plane;
In the first embodiment, insulation is usuallymade of mineral wool slabs stacked in two rows and covered with a special protective layer of cement-bonded boards. This option in the device insulation of attic floor has some advantages:
insulation does not absorb moisture;
freedom of movement on the surface of the insulation material;
the top layer may be impregnated with antiseptics;
If you decide to pereobustroit attic spacefor housing, it is necessary to make it in the first place warm. Previously, as a heater in the ceiling plank straw, hay, sawdust, and later began to use roofing material, slag, expanded clay and glass.
Now to insulate private homes use more modern materials with a number of features, among which are quite highly valued:
low weight, making wooden attic floor does not experience additional load;
simplicity and ease of installation;
high degree of heat saving and protection against moisture.
The most popular materials for the thermal insulation of attic floors are:
It should be noted that these materials, however, like everyone else, have both advantages and disadvantages.
This type of insulation is mineral wool allowsprivate home owners to convert attic space into living space. Mineral wool can be slag, glass, stone - depends on the raw material.
Mineral wool is produced in the form of rolls,slabs or granular mixture, which makes it possible to use this material for the thermal protection of the walls, to make insulation of attic floors, and roof slopes. It can be used for insulation of furnaces, pipes and many other as able to withstand temperatures up to 1000? C. Mineral wool provides excellent sound insulation, as well as resistant to chemicals. The service life of the insulating material is about 50 years. The key to long life - to avoid seals, as a result of significantly reduced insulating quality.
The wooden houses attic insulationwith mineral wool begin with a vapor barrier devices. Some types of mineral wool characterized by water-repellent qualities, so the insulation does not accumulate in the condensate and, accordingly, reduced heat-shielding characteristics. If provided for in the mineral wool foil coating, the vapor barrier is not required.
The disadvantage of such materials is that they contain formaldehyde and therefore to work with them require the use of gloves and masks.
This insulation is made from the gasplastics and applied on virtually any surface spraying. Polyurethane foam is widely used in the device of the roof insulation, insulation of basements, walls, and is also used as insulation for the attic floor.
seamless polyurethane spray method makes it possible tofill almost all the voids and crevices, preventing drafts and cold no chance. This advanced technology allows the insulation to increase almost three times the heat saving, while reducing the cost of home heating. PPU displays considerable resistance to rotting and influence of aggressive media. Polyurethane foam structures attached, it is deposited but which additional rigidity. However, the most powerful argument in favor of foam - a 50-sletny lifetime.
Among the shortcomings of the material it is worth notinghigh cost, which, however, pays off by saving funds spent on work by spraying, because they do not need to perform thermal and thermal insulation cake. Polyurethane foam is perfectly protected from the cold, loud noises, moisture and condensation.
Often, this material is used to insulate attic floor in a private house, Also known as foam, but the technologyand the quality is completely different materials, but they have common components, namely polystyrene. The foam material is quite brittle, while polystyrene is much stronger in compression and tearing. Expanded polystyrene is produced by extrusion, i.e. the polymer at various stages of being transformed - melted and foamed beads, which greatly improves the quality of its insulating later.
To the living room, settle inthe attic was warm enough, try to use such quality penostirolnyh plates as a great thermal insulation. In addition, this material is characterized by low cost, low weight, environmental friendliness and ease of installation. Thermal insulation quality polystyrene retained even under the influence of moisture, because polystyrene is not hygroscopic.
The disadvantages that have attic insulationslab foam is attributed enough good sound insulation, and poor resistance to solvents. Despite the fact that this material is exposed to fire, the new types of non-flammable foamed polystyrene, and have a fairly high grade fire. Currently, there are materials made of corrugated board with a heater from expanded polystyrene and through which there is a great opportunity to insulate the attic floor on wooden beams, and make a loft dwelling.
The simplest and oldest method, whichproduced attic floor insulation - is to use the top-charging materials. Such a method is relevant if there is in the attic of the wooden floors, which is enough to fill the space between the heater all the lags. The whole process of design attic floor insulation in this case is not particularly complex.
Initially, the entire surface of the floor plankkraft paper sheets. But you can use vellum or loose cardboard can also be surface treated clay grease. As already dispensation top layer scatter heat-insulating material, which is to cover the boards to be able to walk freely on the floor. Input hatch attic space must also be well insulated.
