Do-it-yourself insulation of a concrete ceiling 26 photos

The weather conditions of a short summer period and a long frosty winter suggest the use of additional thermal insulation during the construction of houses. The international construction market is saturated with various insulation materials, but experts recommend using mineral wool as an economical and effective material. Thermal insulation for finishing the foundation, walls or ceilings differs in its characteristics, so let’s look at which mineral wool is better for the ceiling and what insulation methods exist.

Foam plastic and expanded clay

Polystyrene foam in appearance resembles foamed plastic material with a cellular structure.
It is usually produced in size meter by meter and is used not only as internal, but also external insulation. Its thickness can vary from twenty to one hundred centimeters. This depends on the type of finishing required. Can be used as a base for ceiling putty. Another feature is its ability to level surfaces.

Polystyrene foam is not only convenient to use, it also has a number of advantages, such as:

Has proven itself as a universal remedy. Quite low cost. Based on this factor, this makes it more accessible to the population. Durable in use. Provides a very high level of reliability of room protection. Has good thermal insulation.

The main component of expanded clay is clay, from which it is subsequently made. It looks like balls and is easy to insulate a room with. The principle of working with it is to backfill it in the attic, so it is only relevant in private homes.

When insulating the roof of a house with expanded clay, you can use these useful instructions to help you carry out the installation correctly. These tips include specific actions such as:

The work process should begin directly with the installation of waterproofing. The choice of means for it is quite large, and all of them are ideal for carrying out this process. It is necessary to cover the rafters and chimney pipe prematurely. For a better vapor barrier effect, a layer of clay should be laid on it. Expanded clay is laid out in layers of at least 15 cm. Thus, thermal insulation is significantly increased .

Expanded clay has a number of advantages, such as:

It is one of the materials that does not decompose over time. Others can harbor various insects and small rodents. Expanded clay completely eliminates this possibility. It is considered fire-resistant and fireproof. It has good sound insulation. It is waterproof. It has frost resistance, which is very important in winter. It has high heat transfer. It is quite low in cost due to the materials from which it is made. It is used not only for ceilings . It can also be used for foundations and walls.

Characteristics

Each product item from the list above has its own unique properties and each has its own positive and negative qualities. Before purchasing a sufficient amount of fastening material, you need to familiarize yourself with the characteristics of each type of disc dowels:

Disc-shaped dowel with plastic nail. It is made from nylon, low-density polyethylene or polypropylene. In terms of their properties, these materials are virtually identical, so they should not affect a positive decision when choosing fasteners. Since this fastening material is made entirely of plastic, it is very light, which allows it to be used in any structure without worrying about the load on the load-bearing wall. But there is also a downside to this - you shouldn’t use them to attach heavy insulation, they simply won’t withstand it.

The absence of metal in the composition of the expansion nail gives it additional advantages - immunity to moisture and poor thermal conductivity. The first advantage makes it impervious to corrosion and increases its service life to 50 years, and the second allows it to minimize heat loss

At the same time, during installation, extreme care must be taken when working with a plastic expansion nail. Possessing low rigidity, it has the unpleasant feature of bending and breaking at the most inopportune moment

Disc-shaped dowel with metal nail. It differs from the previous model in that it uses a 6 mm thick galvanized steel metal nail as a fastening element. This significantly increases strength and allows you to withstand the weight of any structures and use them when working with any type of insulation. And unlike plastic, a metal expansion nail will not break or bend. But this type of disc dowels also has disadvantages. A metal expansion nail conducts heat better than a plastic one and can create areas where the wall can freeze, which will not happen with a dowel made entirely of plastic. The second drawback is corrosion. If the wall remains wet most of the year, then the rust will eat through the entire expansion nail through the unprotected head, which will lead to failure of the entire thermal insulation system.

We recommend: Advantages of houses made of timber

Disc-shaped dowel with a metal rod and thermal cover. This is an improved version of the previous fastener, designed to work in conditions of high humidity. The main difference is the plastic plug that is attached to the dowel head. It prevents the penetration of moisture and reduces the outflow of heat, so such fasteners can be considered more airtight. There are two versions - with a removable plug, which you need to install yourself, and a plug installed at the manufacturer. The second option is more convenient to use, because the plugs are quite small and are stored separately. It is quite easy to lose them during work.

Facade dowel with fiberglass rod. This species appeared on the market relatively recently. It is assembled from the following elements - a clamping part, a fiberglass rod, an anchor element with a spacer zone and an expansion washer, which fits onto the clamping part to create an additional area for fixing the insulation. Thanks to the fiberglass rod, the dowel has high strength and low thermal conductivity. All these elements can be selected separately, guided only by the required dimensions.

Insulation of a ceiling slab: how to fix insulation to the ceiling

How to insulate a ceiling in a private house

The issue of insulating a typical apartment is quite relevant, and everyone solves it in their own way. Some change the glazing, others prefer insulation of walls or floors. But experts are confident that an integrated approach is important in this matter, in which the main thing is not to forget about insulating the ceiling from inside the apartment. It’s easy to do this even with your own hands. There are simple instructions that tell you how to carry out such work.

Why do you need ceiling insulation?

Not everyone understands why it is necessary to insulate the ceiling, for example, in an apartment building. In fact, it is through it that a significant part of the heat generated by the batteries evaporates. And this is due to the laws of physics.

Warm air, heating up, rushes upward and seeps through existing microcracks. The ceiling slab will be able to release heat only when it has warmed up well, but this is unlikely to be possible with central heating.

Step-by-step instruction

Insulation of the ceiling from the inside occurs in exactly the same way as insulation of the walls. First you need to fix the insulation. Then build a frame from a metal profile and install it in the same way as for a suspended plasterboard ceiling.

You need to think in advance about how to fix the insulation to the ceiling - how to hold the mineral wool. It is precisely this that experts recommend choosing as a heat insulator. Synthetics such as polystyrene foam will not help in this case, because it is a vapor-proof material that can deprive the room of the ability to “breathe.”

Note! As a result of the wrong choice of insulation, the level of humidity increases significantly, which can provoke the appearance of mold. Then even forced ventilation will not save

There are two ways to fix mineral wool on the ceiling:

Insulation of the ceiling from the inside

Glue it to the ceiling and press it with a hanging frame. As glue, you can use ordinary putty, which is applied to the ceiling in a thin layer. The insulation is simply pressed against it. If the cotton wool is sold in rolls, you won’t have to hold it for a long time. This method of fastening is applicable only if the height of the suspended structure does not exceed 10 centimeters. If you cover it with drywall, it will be strong and secure.
What to do if a suspended ceiling is chosen as the finishing? Here it is necessary to act somewhat differently. The insulation will have to be glued and supported by a frame, as described above. But then you need to stretch a special vapor barrier film over the frame. It will prevent the insulation from falling off, which will begin to crumble over time. The most important thing is not to confuse which side and where to attach such a film.

Insulation and spot lighting

Many people do not know how to insulate a ceiling slab from the inside without giving up spot lighting. The fact is that by filling the resulting niche in a suspended structure with insulation, we deprive it of its ability to be well ventilated. This means that any lamp, when working, will produce heat, which will have nowhere to go. As a result, the light sources will overheat and fail.

Insulation and spot lighting

And this is not the only trouble. Wires located nearby will definitely melt from high temperatures. It is not difficult to predict the consequences - a short circuit and a fire.

How to solve this problem? Removing some of the insulation around the lamp is not an option. Experts suggest completely abandoning spot lighting in this situation, giving preference to a central chandelier and wall sconces.

If you want to please yourself with the lighting project described, then you can use multi-level ceilings for this. This compromise will maintain security.

The first level in such structures will protect a layer of mineral wool, and the second will make it possible to install spotlights. Multi-level suspended structures can only be used in rooms with sufficient height.

In conclusion

Insulating the ceiling from the inside is not so difficult

It is only important to take into account the features of the technology and follow all safety rules. In this case, you can perform the process yourself

To do this, it is necessary to strengthen the mineral insulation on the ceiling using putty. Then mount the frame from guide profiles, and then cover it with plasterboard slabs or stretch the stretch ceiling film, having previously secured a layer of vapor barrier.

Expanded polystyrene

When it comes to expanded polystyrene (another name is polystyrene foam), the question of how to attach insulation to the walls of the facade is incredibly relevant. The fact is that, unlike mineral wool, it is not attached to wooden walls, it is simply laid in the lathing.

Thermal insulation of brick or concrete walls with this insulation can be carried out simply using glue. We must not forget about the preparatory stage, which greatly affects the final result. In fact, it is not difficult, because it is enough just to thoroughly clean the walls: there should be no dust or any dirt left on them.

It is worth mentioning the need to correct defects in the walls, which are quite possible; for this, use plaster. As for applying the glue, which is necessary for attaching such insulation, it must be applied directly to the polystyrene foam board, use a special notched trowel for this. Important! Do not you need to feed the pharmacies so that hemorrhoids go away once and for all, use a very effective cream...Read more >>>It is important that the glue is applied to the surface evenly, otherwise attaching the insulation to the wall simply may not give the desired effect, that is, with such fastening, ensure normal thermal insulation will not work. But this rule only applies if it was decided to apply the mixture to the entire surface

An effective method is also fastening with glue, applied pointwise to the inner area and completely around the perimeter.

Stages of external thermal insulation

For external insulation, the presence of an attic non-residential space is required. The process of laying mineral wool is simpler than during interior work and takes less time, because the mineral wool is attached not to the ceiling, but to the floor.

We follow the following procedure:

We cover the entire area of the attic floor with a layer of glassine, laying the sheets overlapping (10-15 cm is enough). We glue the joints or reinforce them with tape.

The effectiveness of the vapor barrier layer will increase several times if it is reinforced with sheets of 5-centimeter polystyrene foam. We lay rolled mineral wool of the standard 150-200 mm. We make sure that there are no gaps between the plates. If the rolls are covered with foil on one side, the insulation process ends here.

The sheets must be positioned so that the foil is on top. We fix the material with slats; it is not recommended to pierce the thermal insulation directly with nails. We stretch a thick film over simple mineral wool (without foil) (you can use greenhouse film) and fix it with slats. We glue all joints and joints with double-sided or regular tape.

External insulation with mineral wool - laying slabs on the attic floor

A floor made of any available material is laid on top: chipboards, plywood, boards. Sometimes the roof also requires additional insulation. Thermal insulation is carried out according to the same principle as the option for apartments, but with one caveat - instead of a powerful frame, a light sheathing of counter-battens is sufficient.

Types and materials

Various stores and building materials markets offer a large selection of insulation materials. Against this background, several varieties stand out.

Mineral wool

Mineral wool is a common textile fiber produced by various methods. Fiber made from volcanic materials is called stonewool. Slag wool is created on the basis of blast furnace slag. Glass wool is a raw material created from molten glass. As for the thickness of the insulation, the figure ranges from 2 to 20 cm.

Polyethylene foam

Polyethylene foam in the form of a roll on a foil base is a new generation of insulation. The thickness of this material ranges from 3 to 20 mm. Polyethylene foam is the most effective material used for ceiling insulation. Its small thickness allows it to be easily installed in a private house or apartment.

Styrofoam

Polystyrene foam is a material made from a plastic mass in the form of cells. It is produced in the form of squares measuring 1 x 1 m. The thickness of the sheet ranges from 2 to 10 cm. The density of the material varies between 15-25 kg/m2 (foam plastic 25 kg/m2 is more often used for ceiling insulation). Polystyrene foam is often used to insulate suspended frames, walls and other coverings of a private home. It has good reviews.

Expanded polystyrene

Extruded polystyrene foam is formed by producing special polymers: the finished insulation is created by extruding the material through a special mold measuring 120x60 cm. The thickness of the finished sheet ranges from 10 to 200 mm. For insulation of ceiling structures, material with a density of 25-45 kg/cm2 is often used. In simple terms, this is foam plastic made using a different technology. Its main difference is the higher strength of the material.

You can insulate the ceiling with loose expanded clay. This material is often used for insulating attic floors. In addition to basic materials, insulation can be carried out with isolon, penofol, penoplex

It is important to secure the insulation material correctly. The materials are suitable for insulation on the top floor, veranda, basement, attic

Brief overview of manufacturers

Nowadays it is easy to purchase products for any construction purpose, and mineral wool for the ceiling is no exception. Most likely, the supermarket will offer you several options that differ little from each other.

Brands known for excellent product quality and leaders in the thermal insulation products market:

Knauf (Knauf - an international company); Isover (Isover - an international group); TechnoNIKOL (Russian corporation); Ursa (Ursa - a subsidiary of the Spanish group Uralita); Rockwool (an international group of companies headquartered in Denmark).

For insulating ceilings, both stone wool, produced on the basis of basalt rocks, and glass wool, which is produced after processing quartz sand and glass production waste, are suitable.

Diagram of one of the options for insulating the attic floor

Finally, about backfilling the attic

The use of bulk materials is the simplest option for insulating the ceiling of a country house, although not the most effective. Thermal insulation is carried out on top of the ceiling in various ways:

If you have a concrete auger mixer at your disposal, you can prepare a more modern insulation for the ceiling - polystyrene concrete. The cement-sand mortar is mixed with polystyrene balls and laid on the ceiling in a layer of 200-300 mm. There is no need to lay the flooring - the monolith has sufficient strength.

Note. There is a mistake in the video - there is no need to place the film under bulk materials. Water vapor (especially in a bathhouse) should freely escape through the expanded clay or sawdust concrete to the outside, and the wood should dry thoroughly.

How to attach insulation to the ceiling

Insulation of ceilings is a pressing issue for many in renovation. An insulated ceiling will not just save you from the cold in your house or apartment. But, it will also allow you to save on heating, since with proper insulation, heat loss in the premises will be significantly reduced. However, not everyone knows how to properly attach insulation to the ceiling, and violation of the technology will reduce the effectiveness of insulation work.

Choice of insulation

There are several popular materials that can be used to insulate floors. Depending on the method of work, one or another type can be used, but, as a rule, you have to choose from the following materials:

Mineral wool. Today, this is the most popular type of all similar materials. It is fireproof, has excellent heat saving characteristics and improves sound insulation of rooms. When deformed, it may lose its properties, therefore, it is laid tightly, but without pressing. It can accumulate water, which leads to loss of properties.
Basalt slab. One of the varieties of porous insulation, but with increased fire resistance and moisture protection. In addition, basalt slabs are less susceptible to deformation.
Styrofoam. A well-known material with good thermal insulation properties. It can be flammable, and also does not tolerate ultraviolet radiation, from which it can be destroyed. It is very cheap and therefore very popular. Easy to install using glue.
Liquid insulation in the form of a solution. A modern type of insulation with unique characteristics. Thermal insulation is achieved through a huge number of small ceramic balls placed in a liquid binder. It is applied like paint, after which it dries and forms a non-flammable, moisture-resistant film.

There is no point in considering the last two thermal insulation options in detail - liquid solutions are simply applied with a roller, like paint, and foam plastic is simply glued to a special glue. Therefore, next we will consider how to attach insulation such as mineral wool or basalt slab to a wooden or concrete ceiling.

Concrete base

When working with concrete floors, you will need not only insulation and a minimum amount of tools, but also skills in working with a hammer drill, as well as the hammer drill itself. Work with porous insulation is carried out in the following order:

The ceiling is treated with a primer and the wiring for the lamps is laid.
A certain number of holes are drilled in the ceiling, located in such a way that the dowels inserted into them can hold the insulation.

Using pre-applied marking lines, a frame is assembled on which the outer covering will be held after finishing. He will also create a small niche in which the cotton wool is placed.

Cotton wool or basalt slabs are laid. Both types of material must be secured using special plastic dowels, for which holes have already been drilled in the floor slab. If necessary, additionally secure the insulation with a strong cord.

The entire surface is covered with a special vapor barrier film, which will protect the material from moisture.

The final finishing of the ceiling is in progress.

Wooden ceilings

Working with wood is easier than working with concrete and therefore, a hammer drill is not needed here. If the ceiling is made using joists, then the space between them is simply filled with mineral wool, basalt slabs or foam plastic. The latter can be secured using polyurethane foam, which is necessary to seal all joints and seams. If the ceiling is a flat surface, then you have to do the following:

The frame is assembled first. It can be assembled from wooden blocks or metal profiles. The boring between the frame parts should be selected in such a way that the sheet of insulating material fits tightly into the resulting niche, but without deformation.
The entire space is filled with the selected type of heat insulator and covered with a vapor barrier film.
The final design of the surface of the new ceiling is being carried out.

Installation of sheathing

Before installing fiber cement siding, it is necessary to create a frame on which the panels will be attached.
Stages of frame production:

Fixation of the drainage system on the façade – drainage pipe, gutter
Attaching a waterproofing film to the wall of a building with self-tapping screws
Installation of sheathing from boards - usually a wooden beam with a cross-section of 5 centimeters is used, installing guide vertical slats with a pitch that will be equal to the size of the slab (if insulation is needed, then a layer of insulation is laid between the beams)
Fastening the second layer of waterproofing with slats
Installation of vertical sheathing, which will become the basis for siding: wooden beams with a cross-section of 3 centimeters are attached to the insulation frame

Insulation from below

This type involves the process itself directly from the bottom of the ceiling itself. Materials made in rolls or beams are ideal for it.

This method is considered more difficult and labor-intensive. The process itself includes the following stages of work:

It is necessary to make the fastening using hemming. If this was not possible, you can build up beams on which the installation will be carried out in the future. If it is done using foam plastic, then the process itself is greatly simplified. It can simply be glued to the ceiling. But after this, to increase reliability, it should be additionally secured with dowels intended for these types of work. After the installation process, the ceiling itself, if its condition requires it, can be decorated by painting or using putty.

Thus, you can carry out the fastening with your own hands. The main criterion is the presence of either a suspended frame or specially made fastenings.

If the ceiling height is low, it is better to opt for foil-coated polyethylene foam. The profiles on which they will subsequently be attached can be made of metal or wood. After insulation is completed, if desired, the ceiling can be decorated in various ways, the main ones being painting or installing a stretch ceiling.

Today there is a huge selection of insulation materials that can not only retain heat in your home, but also provide good sound insulation, which is quite important in multi-story panel or brick houses.

Warmth and comfort in the home are one of the first tasks that need to be solved for a comfortable life and preservation of health. In the modern world, where the daily rise in price of energy resources is by no means new, the issue of insulating living quarters is acute.

Scheme of insulation and soundproofing of a wooden ceiling.

To ensure the safety of heat from below, “warm floors” are used; to prevent it from escaping through walls and windows, plastic structures are used.

But it is extremely important to pay attention to heat loss through the ceiling. This is due to the fact that more than 30% of all heat is concentrated at the top of the room. If adequate thermal insulation is not maintained, this will inevitably lead to condensation settling, increased moisture levels and, as a consequence, mold formation

If adequate thermal insulation is not maintained, this will inevitably lead to condensation settling, an increase in the amount of moisture and, as a result, the formation of mold.

How to avoid this, you ask? Is it possible to insulate a ceiling with your own hands?

Of course. In addition, it is quite simple to do, without spending a large amount of effort and material investments. You just need to properly understand the question of how to attach the insulation to the ceiling?

Before considering the issue of attaching insulation to the ceiling, you should pay attention to such an important aspect as the types of insulation. What is the material with which you will insulate your ceiling? After all, only after deciding on this issue, you can purchase it and start mounting it

Sequence of work

As already noted, installation technology will be discussed using mineral wool as an example. However, the process, with minor adjustments, is suitable for other thermal insulation materials. The difference is only in some details; the main stages of work remain unchanged.

Frame installation

This is the main element of the entire structure, determining its durability and aesthetics. You can create a sheathing from wooden blocks or a metal profile. In this case, everything depends on the decorative ceiling. Actually, it is for this that the crate is made. If you intend to install plasterboard as a “finish ceiling”, then it is definitely necessary to use a profile. The fact is that wood becomes greatly deformed when it dries, and there is no fastener that could withstand this. The seams between the sheets crack and the screw heads slip through them.

Lining, MDF and OSB, are more unpretentious in this regard and are attached directly to the wooden sheathing, which is pre-treated with an antiseptic.

In any case, regardless of the material chosen, the work is carried out in the following sequence:

The ceiling surface is cleared of crumbling plaster in compliance with safety regulations, chandeliers and lamps are dismantled.
At the same distance from each other, equal to the width of the insulation, wooden blocks or profiles are attached to the ceiling. Here you need to take into account several nuances. The slats can be attached directly to the ceiling, which greatly facilitates the work. In this case, their thickness should be the same as that of the insulation layer. To install profiles, you need special hangers that are fixed to the ceiling, and the profile is screwed to them.
You will have to install hanging parts often, since plasterboard sheets have a large mass. If the plane is made of concrete, special dowels must be used. You need to leave a gap between the profile and the ceiling so that insulation can be inserted there later. Otherwise, in this place, there will be “poles of cold”.

When all the profiles are installed, the sheathing can be considered complete.

Installation of insulation

Thermal insulation of the ceiling can save up to 10% on heating bills. You just need to choose the right material. The main characteristics of each of them are now known. The owner of the house must decide how best to insulate the ceiling, based on analysis and in accordance with his capabilities.

Victor Victor:

“How to fix insulation on the ceiling in an apartment? “- It will be correct from the roof side, otherwise the dew point will move into the insulation and in winter it will get wet. To protect against heat, I would make a suspended ceiling from plasterboard, for example, using profiles, without insulation.

Polyethylene foam and polyplex

In addition to mineral wool, attaching insulation to the ceiling can be done using other materials, such as:

Foil polyethylene foam. In appearance, it is polyethylene foamed in a special way and subsequently glued to aluminum foil. You can find a similar look in rolls. Their width is standard and reaches one meter, and the thickness can vary from one to twenty centimeters.

It can be used either independently or used in combination with mineral wool to improve the thermal barrier. Also, this combination makes it possible to protect against various carcinogens that can appear due to the use of cotton wool.

Polyplex is the result of extrusion of polystyrene foam. It can be purchased in the form of sheets measuring 60*120 centimeters. The thickness can vary: from one to twenty centimeters. Among the advantages, one can highlight the increased density, due to which it has found its use not only in the form of insulation, but also as a rough base for putty.

From the above we can conclude that both types have their advantages and their installation can be done independently. The polyethylene foam is fastened by gluing it with special glue or using dowels, widely used in construction. The polyplex is attached with dowels or holders that look like the letter P.

Insulation from below

This type involves the process itself directly from the bottom of the ceiling itself. Materials made in rolls or beams are ideal for it.

This method is considered more difficult and labor-intensive. The process itself includes the following stages of work:

It is necessary to make fastening using a binder.
If this was not possible, you can build up beams on which the installation will be carried out in the future.
If it is made using foam plastic, then the process itself is greatly simplified. It can simply be glued to the ceiling. But after this, to increase reliability, it should be additionally secured with dowels intended for these types of work.
After the installation process, the ceiling itself, if its condition requires it, can be decorated by painting or using putty.

Thus, you can carry out the fastening with your own hands. The main criterion is the presence of either a suspended frame or specially made fastenings.

In winter, the heat loss of the ceiling structure is about 15%. Since it is warm in the house and cold outside, condensation forms in the room, creating a favorable atmosphere for the growth of bacteria and fungus. Therefore, it is necessary to think about effective insulation of the ceiling in the interior of the house.

The age-old question - to insulate from the inside or outside

Any external fence separating a living space from the street should be sheathed with thermal insulation on the outside. Accordingly, the insulation of the ceiling on the top floor of a private house is done from the attic side. Causes:

About the notorious dew point, which is used to frighten ordinary homeowners. To avoid condensation inside the structure, it is worth meeting 2 conditions: do not allow water vapor from the room to enter there and use an insulator of sufficient thickness. Then the dew point will be inside the insulation, where there is nothing to condense. The second way is to organize moisture removal using ventilation (read below).

Reference. Dew point is the phenomenon of condensation of water vapor from the air at a certain humidity and temperature. The lower the air temperature, the sooner the degree of extreme saturation with moisture is reached and condensation begins to form.

There are exceptions to the rules; not every room can be insulated from the outside. Examples:

What materials are suitable

In private homes, when insulating ceilings, different components are used that retain heat inside. These include both well-proven and familiar technologies, as well as completely new technologies. The most commonly used are the following:

sawdust;
polystyrene (foam);
expanded clay;
ecowool;
mineral wool.

Of course, sawdust as a material has long been outdated, but it is still used often. The only and main advantage is the price. But their use is potentially dangerous and poses a fire risk. In addition, sawdust shrinks and requires systematic addition.

Polystyrene foam or polystyrene has the lowest heat transfer. In addition, insects and microorganisms do not breed in it. The cost is reasonable. If the choice is in favor of this particular product, then you need to ensure good ventilation and systematically carry out complete ventilation, since it does not allow oxygen to pass through. However, it does not meet fire hazard requirements.

But expanded clay is more suitable for external insulation. Lightweight and porous building material made from high-temperature resistant clay. Mice and rats will never live in it. It has a good level of sound and heat insulation and is not susceptible to water. It is distinguished by sufficient weight, as a result of which a screed is often made on top of it.

Another relatively new product is ecowool, created on the basis of cellulose and containing antibacterial substances. It has good elasticity, vapor conductivity and elasticity. When a fire occurs, it begins to smolder, that is, it is fireproof.

Mineral wool is an environmentally friendly product. It is widely used for thermal insulation, as it retains heat and excess noise well, and also promotes the removal of steam. Vata can be divided into several subspecies:

Stone;
Varnish;
Glass wool;
Kemamicheskaya.

Under no circumstances should this material be compacted. When you lay the insulation you need to control it to prevent the formation of cracks. Before work, be sure to wear safety glasses, a respirator, gloves and clothing made primarily of very thick fabric.

Answers from experts

Sergey:

In general, insulation is installed on the cold side. If you do not have this opportunity, then increase the thickness of the insulation and install a vapor barrier (such as a universal one - isospan D) from the bottom of the insulation with gluing the seams, and only then finish the ceiling. No moisture or steam should enter the insulation layer.

Stas Shabanov:

I would like to look at the installation diagram of the insulation; it is not advisable to attach it from the inside. Sometimes even the presence of a vapor barrier can be a problem. Or ventilate or remodel more often.

Mikhail Godunov:

Is it 100% foam insulated?

Andrey:

There should be waterproofing on the ceiling under the insulation. Insulates from internal moisture. There should be nothing on the insulation for ventilation.

Alexei:

for timber - moisture insulation (their sea), then - slabs of dense foam (they have different names and looks, but you need one that has grooves for joining and cannot be cut with a knife, thickness up to 4-5 cm, on it a plaster mesh (preferably galvanized), level with sand concrete (m300) and apply tile adhesive - tiles - that's it! (the mesh and slabs can be fastened with façade dowels directly into the timber (those with a large plastic cap and a metal nail in the middle of the plastic body - there will be no heat transfer through them. that's all I did your repair in 3 minutes (wrote), you should do it faster too!)))

Dim-Dim:

If you poop in winter then if not in summer

Valentina M.:

It is necessary to insulate from the outside to prevent the formation of the so-called. a bridge of cold in the walls. Look at what insulation materials are sold in your area, what their thermal conductivity coefficient and resistance to dampness are, then calculate the consumption and price of the issue. Do not strive to save at any cost; heating the atmosphere and replacing rotten logs will cost more. If possible, and you live in cold regions, insulate the inside as well.

INTERCEPTOR:

How thick is the timber? If it’s 150x150, then you can create a ventilated façade on the outside; that is, there must be a gap between the timber and the finishing material of the façade so that the timber can be ventilated. Nail parchment paper to the beam. Inside there is slab insulation, URSA or ROKVOL, whatever you want, but it must be a pressed slab. Then you can shoot a polyethylene film and on top of it the finishing material - PVC panels - MDF, etc.

Lukin Sergey:

It’s better to insulate the outside, there are a lot of materials, both siding and aquapanels, and there is insulation between the siding or aquapanel. The inside can be covered with gypsum fiber (you can glue tiles onto it; it is moisture resistant.

Proper ceiling insulation avoids common mistakes.

The first and important point is the choice of thermal insulation materials - insulation, when preference should be given to those that are suitable for the temperature difference in your region and humidity level, i.e. to climatic conditions.
The second point is to find out the ability of the thermal insulation material to absorb and release heat, i.e. how quickly a concrete ceiling insulated with this material can cool or heat up.
The third point is to know the ability of the insulation to absorb vapor formations from the surrounding air (a feature of bathrooms and kitchens).

Insulating ceilings with your own hands - What else needs to be taken into account when choosing insulation.

1. The best option is when the insulation has low thermal conductivity, is light and thin. But such insulation is expensive.

2. But you shouldn’t skimp on such insulation characteristics as moisture resistance and fire safety.

3. In our age of environmental distress, try to choose an environmentally friendly material.

4. The insulation must be durable and elastic.

Ceiling insulation with stone wool is an inexpensive way to prevent heat loss through the ceiling, whether installed inside or outside the room. The quality of work depends on competently performed operations, so in this article we will consider the rules for placing and attaching the insulator to the surface in various situations. Using our recommendations, you can avoid unnecessary financial costs and common mistakes when insulating.

Features of thermal insulation of ceilings with stone wool

Stone wool is a fibrous insulator made from basalt. To improve its characteristics, various substances, including hydrophobic ones, are introduced into its composition. The material is quite loose, saturated with an inert substance, and does not allow heat to pass through.

To avoid skin irritation, wear thick clothing with long sleeves and gloves. To protect your eyes and respiratory system, wear goggles and a respirator. After work, change your clothes.

It is often said that cotton wool is very dangerous, but this statement is not true. Modern technologies completely isolate the coating from the living space, and it will not bring trouble to anyone.

Advantages and disadvantages of ceiling insulation with stone wool

The fibrous material has unique characteristics, thanks to which it is considered the best among similar products.

Very low thermal conductivity, which creates a comfortable indoor environment.

Users should be aware of the problems that sometimes arise when operating a room insulated with cotton wool:

Unscrupulous sellers may sell low-grade goods with a high percentage of toxic elements.

Features of installation of mineral wool

Modern types of mineral wool are completely safe and do not emit any harmful substances during operation. But during installation you must follow certain rules.

With any type of mineral wool, microscopic fibers are separated during installation. They can get into a person's eyes and lungs, and penetrate under clothing. Glass wool is especially harmful to health, since the smallest glass needles do not dissolve in the lungs and can provoke the development of complex pulmonary diseases.

Therefore, it is recommended to work with mineral wool in a closed suit, gloves, goggles and a respirator. At the end of the work, you need to take a shower, throw away your clothes or wash them thoroughly.
