How to warm the attic
The simplest and most affordable way to convert an unused attic into a dwelling is considered to be facing its ceiling, walls and floor with any suitable heat insulator for this purpose. We will try to tell you about the correct attic insulation in your country house without significant expenses.
For the arrangement of the upper floor should be used materials with the following characteristics:
- high moisture resistance;
- low thermal conductivity;
- resistance to fire and the spread of combustion.
They must be environmentally friendly and safe for the health of people living in the house.
For insulation attic used:
- industrial glass wool;
- extruded polystyrene foam or foam;
- mineral wool.
When refitting the attic space one should not forget about the mandatory hydro and vapor insulation of individual structural elements.
Warming of the roofing part (ceiling)
Warming from the inside begins with the finishing of its roofing part, and the general order of work performed is determined by the type of protective material.
Heat-insulating slabs of wool are usually placed between the rafter legs on the entire thickness of the latter, so that these elements of the roof structure are completely closed during the subsequent finishing of the ceiling. But sometimes the owners of the house plan to use rafter beams as a decorative element, particularly prominent in the interior of the room. In this case, during the warming it will be more convenient to use foam polystyrene or polystyrene plates, placed in a thinner layer between the rafters.
Note! When using mineral wool (glass wool), it usually takes a little longer to warm up than when using foam plastic or polystyrene. To achieve the desired effect, mineral wool should be laid in several layers with mandatory additional vapor barrier.
Insulation of walls (building gables)
The gabled parts of the attic, which are the end walls of the attic, are considered to be the most unprotected from outside cold air. When they are isolated, the greatest effect can be achieved by insulating the outer surfaces of the gables made of a particular material (brick, bar, rounded logs or foam concrete). External thermal insulation of the gable parts is carried out in the course of general construction work and involves the use of additional structures or devices (scaffolding, for example).
The longitudinal walls are insulated with the same insulator as the roofing part (this is not the case when roof slopes are used as the ceiling and walls). Working operations for the internal insulation of walls are not much different from those already discussed by us earlier, with the exception of some small details.
Note! If mineral wool is used for wall insulation, preference is given to insulation material made in the form of mats. With rolls of the same class, difficulties may arise related to their fastening.
Floor insulation
When insulating the attic from the floor, special attention should be paid to the vapor barrier protection of this part of the building that has direct contact with the main living quarters. In buildings with wooden beams for this purpose, a well-known type of vapor barrier is used, such as “Izospan”, laid down with a rough surface down. In the process of its installation between the adjacent canvases, an obligatory overlap is made with an overlap of 20 cm. The second layer over the insulation is fixed on the beams by means of thin wooden slats.
For insulation of the attic from the floor, any suitable insulation material (ecowool, in particular) can be used, the plates of which are placed between the sexes. In addition to reducing heat loss through the floor, provides good sound insulation of the room.
Note! To improve the efficiency of insulation procedures, ecowool can be stacked in several layers.
