The insulation of the attic overlap of the house allows you to preserve more heat inside the room, and not to spend it on the heating of a cold attic. Well, if it is used as a utility room (technical attic) or as a attic, and if not? Then and spend the resources on the heating of a unwanted attic room meaningless.
It is, so it is worth making insulation overlapping a cold attic using thermal insulation materials. You can perform insulation on the side of the attic or from the room (from the inside / outside). It is best to do this during the construction of a building, or immediately before finishing the room. But during the operation of the house there is no reason not to insulate the ceiling overlap from the attic.
Warming of the attic overlap of minvata, foam, sawdust, clay
The thickness of the insulation of the attic ceiling is normalized using SNiP II-3-79 "Building Heat Engineering". This manual contains detailed recommendations regarding the choice and formula to calculate the heat transfer resistance of various thermal insulation materials. In the calculations, not only the type of material, but also the average annual temperature, the duration of the heating season, the wall material of the house is taken.
The technology of insulation of the attic overlap depends on the material selected.
Comparative characteristics of heat-insulating material with equal thickness
In this article we will consider the most popular insulation.
Insulation of the attic overlap of Minvata
Mineral wool is a heater whose fibers,Located in a certain way. It is that this chaoticism leads to the fact that
Between the fibers, an airbag is formed, which reports to insulation
His properties. However, the same feature of the wool increases the ability to absorb
moisture. To avoid this, you need to know how to perform installation
Minvati.
Advantages of mineral wool:
- high density;
- long service life;
- Fire safety;
- ease of installation;
- Using mineral wool for horizontal insulation
surfaces does not lead to it, crashing and education, as a result,
Cold bridges.

Among the shortcomings: the ability to absorb moisture.
The technology of insulation of the attic overlap of Minvata
There are three main ways to lay watts: skidding, in
grooves or cells (see photo). The choice of method depends on what load
It will fall further to the floor. The most stable frame is obtained in
Last case.
Insulation of the attic overlap of Minvata
First stage
Starts with laying a vapor barrier film. Film
will allow pair that rises from warm dwelling on
Cold attic. To lay the film correctly need to carefully read
with marking applied to it. Be sure to comply with the surveillance of 100 mm.
The technology of insulation of the attic overlap of minvatoysli is insulated on wooden beams, the film should ride all the protruding elements. Otherwise, beams can suffer.
In the fields of the joint of the film and walls or other protruding surfaces, it is necessary to raise it on the height equal to the thickness of the insulation plus 50 mm. and sneak tape or wrap on the insulation stove.
Second phase
The insulation laying (wool) is performed. It is pretty simple
process. Plates or stripes are easily cut by a construction knife on the necessary
sizes.
Laying sheet need to ensure that no gaps remain or mineral wool
The material was not greatly composed. Both will lead to a decrease in quality.
insulation. Typical errors in the photo.
a) insufficient thickness of heat-insulating material;
b, in, d) incorrectly chosen the thickness of insulation of the attic
Overlapping.
Useful Mounting Tips Minvati
- Insulation with foil increase material resistanceheat lines. Sheets the leaf foil side down.
- The insulation should not be for the beam. If it is formed
Such a situation, the beam needs to be lengthened by a wooden bar or a good rail to
Solar thickness.
- laid in two layers Thin insulation saves more
Heat than one fat. At the same time, the plates need to be laid in a checkerboard.
- If in the attic there are protruding structural elements, for example,
Pipe of chimney, you need to raise the insulation to a height of 400-500 mm. And consolidate it.

Third stage
It is carried out by floorproofing if the attic is not
It is supposed to be used, and the rafter system is not protected by waterproofing
Film. If the roofing material is separated from the attic film, then you can
Start with the final stage.
Rough floor. It feels over the insulation and serves as the basis
For final finishes.
Insulation of the attic overlap of foam
The process of installation technology is similar to insulation of the atticOverlap polystyrene.
The advantages of these materials:
- low cost;
- simplicity;
- Waterproof.
Among the shortcomings: flammable.
TREATMENT TECHNOLOGY OF CIDS foam or polystyrene foam
The process of installing hard insulation based on foam is more than simple
And it can be done with your own hands. Works can be divided into two stages:
- Aligning surface. To provide quality
Insulation on the floor of the base should not be significant irregularities. Eliminate
Such drops can be filled with sand-cement mortar.
- Laying the plates is made of jack or between bars.
The presence of a bar increases the strength of the floor.
Tip: Thoroughly seal any seams, incl. Shakes S.
beams. Coming over an obstacle, try to cut holes as accurately as possible.
The homogeneous thermal insulation layer is better preserved heat.
Insulation of the attic overlap Foamforastractor
Polyfoam must be protected from destruction by film on non-residential
attic. At frequently used or residential attic, you need to move somehow, so
top of the foam or expanded polystyrene is better to equip the draft floor from OSB or
Run sand-cement screed.
Warming of the attic overlap of sawdust
Sawdust is fine wood.Benefits:
- naturalness;
- lack of toxic impurities;
- low weight;
- availability of material.
Disadvantage - flammable.
Insulation technology attic sawdust
- Before you begin to insulate sawdust, they need them
Prepare. Namely, mix cement and water in the ratio of 10: 1: 1.
- A finished mixture to pour the sex of the attic and to dissolve. Worth it
Note that applying sawdust as a heater without the use of a frame
You can only on a non-residential attic. Otherwise, when walking on the floor, sawdust
They will be compressed, and the concrete screed collapses.
- Build a cellular structure from a bar. Inside each
Cells pour a solution with sawdust. The advantage of this method is that by
Brusa can be asked the draft floor. And the attic will be suitable for operation

Warming overlapping attic clay
Ceramzite is obtained by firing clay.Benefits:
- Low thermal conductivity;
- naturalness;
- environmental friendliness;
- ease;
- availability.
The disadvantage is associated with the complexity of the lifting of the ceramisite to the height of the attic.
Ceramizite is usually used if you need to perform insulation of the attic
Overlap by plates.
Insulation Technology Indian Ceramizite
Works are performed in three stages:
- The stove is examined for the presence of cracks and cracks. Them
Close up with a solution or covered with tight paper. Protruding elements
Handling difficulties are not created.
- Mount the crawl from the bar. There will be in the future
Women's black floor.
- Bulk insulation pour on the stove and align with
ordinary rake. Layer thickness 250-300 mm. You can move on the cerazyt without
restrictions.
Warming of overlapping attic ceramzitomyovis: when dripping the claying, it is better to combine the granules of different sizes (diameter). So you can avoid the appearance of emptiness.
At the end, the draft floor is mounted or poured with a sandy cement screed.
Pay attention to the insulation of an attic wooden
The overlap has some nuances:
- The tree is susceptible to rotting, which means steam, rising
Up should be free to pass. Incorrect installation of films or use not
Breathable materials, for example, rubberoid will lead to the destruction of wood in the future.
- Using a foil insulation, you need to post it.
Foil down. So wood will be protected from water from entering and at the same time
Will accumulate pair moisture.
Insulation mistakes attic
- "Right" - use superdiffusion membrane or
Film Parobarmer
- "Wrong" - lay a special film without
marking or generally ordinary film
