DIY attic insulation is a fairly responsible task that requires a competent approach. If it is planned to build a house with a subcutaneous room, the selection of thermal insulation for the attic must be done when designing. In this case, it is necessary to take into account a number of important points.
First of all, the configuration of the roof and the size of the attic matters. The second important factor is climatic conditions. It is obvious that it is necessary to warm the home on the warm sea coast and the house behind the polar circle in different ways. It is impossible to change external conditions, and it is necessary to correctly choose the thermal insulation and technology of laying insulation — it is necessary.
We insulate the attic according to the rules
People began to use the attic as a dwelling for a long time. It is believed that this experience came from the French. They have long covered the roof with tiles of burned clay. On warm days, the attic with such a roof warmed up remarkably, and the French took advantage of this.
It was beneficial to settle in the attic — they did not take a fee for living. But it was impossible to live in the cold in the cold, involuntarily I had to think about warming. The assumption is quite justified that with the advent of high -quality insulation, the popularity of attic increased in other countries.
Often, the owners of private houses and cottages are landscaping attic rooms on their own. Significantly facilitates this task, providing the opportunity to save time and means, an extensive assortment of insulation and necessary for its laying materials.
Insulation is necessary not only for the roof, but also for walls and floor. The insulation is selected so as to avoid critical load on the walls and ceilings. It is strictly not recommended to use artisanal production materials. You need to choose insulations that do not have an unpleasant odor.
The attic has its characteristic features that must be taken into account when arranging it. From below, wet warm air penetrates here from the rooms. The wind blows from above, precipitation falls. Therefore, the insulation in the attic is not enough only to fix it well, it must also be protected.
When equipping the attic with your own hands, you need to follow the work order. Insulation from the inside start from the roof. First, windproof material is strengthened. The next step is the frame and thermal insulation is fixed. Vapor barrier is laid on top, then finishing is carried out.
How to protect the insulation from the wind?
For all heaters, insulation from powerful air flows is required. As experience shows, in the absence of such insulation in the room, drafts will walk, which is a direct cause of heat loss.
To prevent this nuisance, you can use roofing material or polyethylene film. And the membrane specially designed for such purposes will work best. She will pass the air in only one direction and will not let moisture get inside.
What to choose — to solve the owner. The main task is to protect the insulation from rain and snow. At the same time, not forgetting that moisture can fall into the room with gusts of wind from the roof.
Vapor barrier for insulation
When landscaping the attic, it is necessary to take into account the increased humidity of the air here. This factor is due to the location of this room.
You can protect the insulation from steam using polyethylene film or Pergamine. It is not worth using roofing material in this case.
Since the fixation of the material will be carried out on an inclined plane, it is more convenient to work with a partner. The gaps between the sheets of insulating material should be thoroughly glued with building tape. The next step is finishing.
Selection of materials for insulation
The choice of thermal insulation for the attic depends on many factors. The configuration of the roof, the thickness of the walls of the house itself, and climatic conditions are important. All these circumstances take into account the design documentation. You should not start work on the improvement of the attic room without appropriate examination and proper preparation.
An important point — assessment of the necessary technical parameters of insulation. Manufacturers offer various types of insulation. Each of them has its own characteristics, such as the coefficient of thermal conductivity, resistance to fire, density that determine the area of their use.
The following heater are suitable for landscaping the attic:
Mineral wool;
fiberglass wool;
foam;
polyurethane foam;
Often chosen insulation on a mineral basis or glass wool. For the attic, a layer of such insulation should be 15–20 cm thick. These materials attract at their price and universality. The least costly option — foam. But it should be borne in mind that he is fire hazard.
The thermal insulation materials produced by Knauf showed themselves from the best side. This brand offers materials for thermal insulation of any rooms, from basement to attic.
Thermal insulation of the attic must be:
strong;
light;
Tough enough;
Resistant to deformation.
The insulation materials of the Knauf brand showed remarkably in the improvement of attic rooms. Insulation is produced by various densities suitable for any situation. He goes on sale in various types: rolls, mats and slabs. Before choosing one or another form, you need to accurately calculate.
When developing a project, when the surface area for insulation is known, the technology for performing work is considered in detail. Practical experience in performing certain operations is important in this matter.
Mats and slabs are easily attached by one person, assistants are not needed. And it is more efficient to work with rolls together. The canvas can be fixed immediately from the roof to the ceilings. Excessive savings on warming materials can result in insufficient quality of thermal insulation.
DIY insulation from the inside with your own hands
Tricking specialists concluded: well-selected thermal insulation will prevent heat leakage in cold weather and provide coolness in the summer. In a coat, it is impossible to provide the necessary comfort if the walls and ceilings are not insulated.
It is important and correctly selected and correctly put. Glass wool mats and mineral slabs are recorded using the same technology. Work should be carried out in overalls and with means of protecting the bare areas of the body.
The simplest method of insulation is to fix the mineral slabs between the beams of the rafters in two layers. In this case, the joints of the first layer are overlapped.
Fixing the insulation, it is important not to damage the film that serves for waterproofing. After the slabs, or rolled fiberglass are fixed, a vapor barrier film is laid on top.
Not so long ago, people increased the living space with the help of attic premises, so the attic were insulated from the inside. Now private houses are designed with the attic. This approach is quite economically justified. To improve the attic at once is much easier than after the construction of the construction.
