The need for insulation
The Ministry of Service is produced with a thickness of 5 and 10 cm. For the ceiling, the most suitable option will be a decade-cated heater. Finishing with such material allows you to solve several tasks at the same time. In addition to thermal insulation, the use of this material will prevent the penetration into the placement of foreign sounds. And also will prevent the formation on the surface of the ceiling condensate, which causes the appearance of fungi and mold.
The insulation of the Ceiling of Minvata in a private house is necessary if there are following signs:
- the occurrence of coolness indoors with a working heating system;
- the appearance of the frost in the ceiling region;
- the formation of a high level of humidity in the room;
- the appearance of a sharp difference in temperature.
No less useful to use Minvati in the apartment. Recently, the widespread dwelling trend has become widespread. Owners of apartments, seeking to increase the living area, combine rooms with loggias and balconies. Montage Minvati on the ceiling in this case will save the comfortable temperature indoor.
Characteristics of Minvati
Mineral wool has a significant amount of advantages:
- First of all, the available value of the material should be highlighted, which helps to increase its demand.
- It is easy to work with it. The insulation of the ceiling of the Ministry of Service is under the power of both a specialist and non-professional.
- This material is distinguished by stability to a number of negative factors. For him, there are no threats and various pests, such as bugs or mice. Wat is not exposed to mold and rotting processes.
- Material is resistant to ignition. It does not burn in the event of a fire prevents the spread of fire.
- In addition to the heat-insulating effect of Minvata, it provides high-quality sound insulation, which is explained by the characteristics of the structure. Its fibers are located in chaotic order, which prevents the formation of sound waves.
- There is no unambiguous opinion regarding environmental safety material. In the Ministry of Service there are carcinogenic substances (phenol formaldehyde and melamine-formaldehyde resins). But, according to manufacturers, the concentration of these elements is so small that the insulation does not represent health hazards.
- It also has a high degree of vapor permeability. This quality allows in a warm time to prevent overheating of the room, and in the winter it is to bring out extra evaporation.
- Due to good strength, the material is able to withstand significant mechanical loads.
- Minvat has a long service life. When providing certain conditions, it is capable of listening to 70 years. In addition, during the specified period of time, the material will maintain its original form.
- This insulation is not exposed to a natural or thermal shrinkage, which eliminates the penetration of cold air through the joints.
But when choosing mineral wool as a heat insulation coating, it should be borne in mind that it has hygroscopicity. This insulation absorbs moisture well, as a result of which loses its operational characteristics. For this reason, in the process of insulation, use waterproofing. Polyethylene film or foam applies for this purpose.
Methods of thermal insulation of mineral wool
Mineral wool for ceiling insulation is used from the outdoor and inside of the attic. External isolation is mandatory. And for internal heat-insulating works, installation of the mounted ceiling structure will be required, which is not entirely advisable if the work is carried out indoors with a low ceiling.
In some cases, a combination type insulation is used when the material is stacked outside and inside the building. This option is provided for premises in which the elevated temperature level is maintained for a long time. For example, the ceiling insulation in the Ban of Minvata will allow the necessary temperature regime.
The order of insulation from the outside
To work will be required:
- insulation sheets;
- mounting foam;
- polypropylene or polyethylene film;
- scissors or knife;
- roulette.
To achieve a higher thermal insulation effect, minvatu are laid together with foam. And the workflow itself is performed in such a sequence of actions:
- The working surface is initially needed to be cleaned of contamination.
- The film is cut into stripes, the width of which should slightly exceed the space between the overlap. As a waterproofing, another material with high vapor permeability can be applied.
- The film is placed between beams and fix it along the edges.
- When using foam, this material should be laid on vapor barrier.
- All gaps are filled with mounting foam.
- The sheets of mineral insulation are placed on top of the foam.
- If insulation is carried out only with the help of minvati, this material immediately places the vapor barrier film.
- In the process of work, gaps and gaps should be avoided. For warm terrain, one insulation layer is sufficient. In the regions where the cool climate prevails, the mineral wool for the ceiling must be laid in 2-3 layers.
- The sheets of each subsequent layer should be placed in such a way that the joints of the previous one overlap.
- To avoid heat loss through wooden beams, they should be closed with insulation.
- After the thermal insulation layer is laid, it is covered with a film. This will protect the insulation from moisture penetration.
- The jokes of the film are sticking with scotch.
- On this work on the laying of thermal insulation is completed.
How to insulate the ceiling by minvata indoors
Previously need to prepare:
- insulating material;
- wooden planks or metal parts;
- material for mounting the mounted construction (plastic, plasterboard, etc.);
- wire or adhesive composition for fixing tiles.
The process of thermal insulation occurs in such a sequence:
- Initially, the surface of the ceiling should be attached to the vapor insulation material to prevent moisture penetration from above.
- Then the frame from the board with a cross section of 30 mm x 100 mm or metal profiles is established. However, the markup is pre-performed. The surface is far from all the ceilings is completely horizontal. It is necessary to measure the distance from the ceiling to the floor at several points. You should navigate the smallest indicator.
- On the walls with a pencil or marker, marks are made, which correspond to a smaller distance and are connected by the line.
- On this guideline, the framework details are installed. Intermediate elements must correspond to the height of the guides.
- If the frame is made of wooden planks, a small fragment of wood is put under each of them to provide a horizontal design level. When mounting the frame of metal elements to the ceiling for this purpose, suspensions are attached.
- For fixing, nails or self-tapping screws are used depending on the material from which the frame structure is mounted.
- Between its elements stacked the plates of the insulation. If necessary, you can form several layers. This approach is used in cold rooms.
- To fix the material, glue is used, with which the ceramic tile is stacked.
- When working with a rolled insulation, fixation is performed by another method: 15 cm in the frame robbed nails. The end of the wire is brought to the last nail.
- During the laying of the material, the wire should be stretched between nails, forming a zigzag form. As a result, it turns out a grid that will firmly hold the material.
- After completing the laying, the Minvati mounted mounted ceiling.
Ceiling arrangements after laying insulation
Consider how to install the attached construction from the most common materials:
- plastic panels;
- sheets of plasterboard.
PVC material panels are produced 50 cm wide and 25 cm. To determine the required amount of these items, you need to calculate the room area and add another 10-15% on the resulting number. Special fasteners are used for fastening. The workflow looks like:
- The first panel must be taken to the P-shaped profile and attach to the frame by screws or clips.
- If necessary, you can cut off the material with a hacksaw or an ordinary knife. Plastic is well cut.
- The next panel is applied to the castle of the previous one at a minor angle and start over the entire length.
- The second end is attached to the frame with the help of screws.
- When installing, a strong mechanical impact on the panel should be avoided. Plastic is a rather fragile material, with an inaccurate handling it is easy to damage it.
- The last band can be installed in two ways. According to the first method, the panel turn over the lock in the opposite direction and cut from the side of the previous strip. After that, the strip is fixed by screws. The second option involves snapping the lock with the previous panel and trimming on the other side.
- The final stage is the installation of plinths.
The mounted design of plasterboard is installed as follows:
- Fastening sheets is performed according to chess order. That is, the material is located in the transverse direction relative to the longitudinal profiles and in the longitudinal relative to the bearing elements.
- The first fragment is installed on the wall, subsequent - from the first longitudinal profile.
- Sheets are fixed through metal screws every 20 cm.
- There is 2-3 mm space between the gypsummock fragments.
- The joints are sealed using a special mixture to which the reinforcing fiberglass stack is superimposed.
- The composition is leveled with a wide spatula.
- After drying, the joint is processed by fine-grained emery paper.
- Similarly, gaps are processed between plasterboard sheets and a wall.
How to insulate the Ceiling of Minvata: recommendations for work
- Since the minvat has a small fibrous structure, when working with it, use the respirator and special clothing. Getting into the respiratory tract and fibers to the skin provokes irritation and itching.
- With incorrectly produced calculations, the insulation layer may exceed the width of the crate frame. Actions in this situation depend on the material from which the lamp is performed. Wooden frame needs to be supplemented with additional bars. If the case is metallic, it is necessary to reduce the Minvaty layer or replace the suspensions.
- If the frame is made of metal profiles, there is a possibility that cold air will penetrate in the area of \u200b\u200bcorners through the ceiling. To avoid this, after installation, the corners must be treated with mounting foam.
- As the fasteners, the steel screws with frequent cross section are recommended when working with metal profiles.
- In the process of installing Minvatu can not be tamped and pressing. As a result of these actions, the number of air bubbles will decrease, and the material will lose thermal insulation properties.
- In those zones where point lamps will be installed, it is necessary to provide free space. This is necessary to ensure air circulation, in the opposite case, you can encounter the problem of regular burning of lighting devices.
- After the completion of the work, it is possible to determine the quality of insulation using the thermal imager - the device that is able to detect the cold penetration sites, if any.
Conclusion
Mineral wool has high thermal insulation qualities, which makes it possible to create a comfortable temperature level indoor. And also significantly reduce heating costs. But the effect of this material is not limited to thermal insulation, with its help you can solve a number of other operational tasks. This insulation is easy enough to use. The insulation of the ceiling of mineral wool does not require qualified knowledge and experience.
