Wall insulation material inside

Often, when in old houses it is necessary to insulate walls inside the apartment or completely replace thermal insulation with a more technological insulation. It is important here to choose the right material and correctly install it, otherwise condensate will begin to accumulate and mold develop directly inside the walls. And deleting the consequences of incorrect thermal insulation is very expensive and laborious. Therefore, do not rush, but calculate the possible options and choose the only right solution.

Foam polystyrene

Or as it is also called polystyrene (PPS). This most common insulation is obtained using polymerization of styrene, which is heated and foamed under the influence of a gaseous substance. The resulting granules can be filled up in horizontal overlapping for insulation, but in most cases already compressed blocks or plates come on sale.

PPS has excellent thermal insulation properties and practically does not absorb moisture. When warming, they do not have to build the formwork and carry out additional work on waterproofing and vapor barrier of the walls. It is undemanding during operation, and with proper installation for several decades, retains its properties. In addition, its low price is also attractive. But the choice of material for insulation of walls inside the house should be approached with great responsibility, and the low cost should not prevail in this matter. The PPS also has a number of disadvantages that are not so important for insulation of walls outside or non -residential premises, but for apartments and private houses are a serious danger.

Flaws:

• foam fuel, and when burning, emits toxic substances dangerous to human health;
• pPS plates are very fragile and easily break, so very often you have to buy material;
• almost always, rodents are starting in the PPS, which are happy to equip their holes in it. This leads to the destruction of the insulation and to the need to use special chemicals.

Extruded polystyrene foam

It is also used to warm walls from the inside. It is a rigid plate of polystyrene granules, a mixture of gas and a foaming agent. This is a universal insulation that is used for thermal insulation of walls, basements, freezers, high -humidity, etc.

It has low thermal conductivity and is practically not hygroscopic. It is not subject to destruction under the influence of the environment (temperature difference, atmospheric precipitation). Extruded polystyrene foam can be ignited when heated, but when removing the source, fades. When burning, it does not distinguish harmful substances.

Despite all the advantages, extruded polystyrene foam (EPPS) has low vapor permeability, which leads to a poor microclimate in the room. Therefore, during insulation, the ventilation system must be provided.

And with a long stay under direct sunlight begins to collapse and lose its thermal conductive properties. Under ideal operating conditions, the service life does not exceed 30 years.

Mineral wool

This is an excellent material for insulation of walls inside and outside based on basalt, slag, etc., mineral wool is produced in rolls or plates and has a different density, on which thermal insulation qualities and price depend. The roll material is suitable for insulation of ceilings and floor, and slabs are used for walls.

Advantages:

• the insulated mineral house preserves heat well in winter and is protected from overheating in the summer;
• good sound -reflective and sound -absorbing properties of the material. Material with a more loose structure absorbs air noises well, and more dense isolates the room from sounds that appear as a result of a blow;
• it is important, especially for the dwelling, and the fact that mineral wool belongs to non -combustible materials. And with direct contact with fire, it does not emit toxic substances and practically does not form smoke.

Flaws:

• the declared security of the material is quite arbitrary. In the manufacture of mineral wool, a binder is used, which can distinguish phenol;
• work with her is not as dangerous as with fiberglass, but also requires mandatory protective equipment.

For insulation of walls indoors, it is best to use basalt cotton wool made of super -thin fiber, since its composition does not have a binder. After laying the insulation, it is closed with a vapor barrier film that protects it from condensate, and the room from small particles of the insulation.

Glass wool

This is one of the most famous thermal insulation materials, but in recent years its popularity has fallen due to the appearance of more new and technological insulation. It is made on the basis of glass waste, which in the structure are represented by wide fibers up to 5 cm long.

Advantages:

• high elasticity. For storage it can be compactly pressed, and if necessary, it will quickly take its original size;
• high resistance to vibration;
• non -toxicity;
• excellent sound and thermal insulation properties;
• fireproof;
• not subject to the formation of fungi and mold;
• it is not damaged by pests.

Flaws:

• in comparison with other heater, a lower operational period;
• some types of glass wools contain formaldehyde;
• when working, protective equipment for the whole body and face will be required.

At the last and, perhaps, the most important drawback should be stopped in more detail. If you neglect the precautions when working with glassy, \u200b\u200band it will get on the skin, the strongest itch will begin, from which, for a long time it will not be possible to get rid of. And when the material gets into the respiratory tract, the risk of serious and irreversible health problems is likely. All clothes and a respirator after work must be immediately thrown away.

But this drawback with more than pays off an excellent combination of high thermal insulation properties and low price. It is enough to observe caution in the work, and then with small financial costs it will be possible to qualitatively warm the walls of the house from the inside.

Ecowata

This is a light insulating material based on cellulose. It has a loose structure of light gray or gray. It contains wood fiber, boric acid and drill as an antiseptic.

Advantages:

• environmental friendliness. All components in its composition are of natural origin and are safe for humans and the environment. Thanks to this, it was listed in the register of natural and safe materials, and hypoallergenic and hygienic qualities are confirmed by certificates. In case of fire, Ecowatus does not emit toxic substances;
• good thermal insulation properties. This is due to low breathability, low thermal conductivity and thin -fiber structure. As practice has shown, the thermal conductive properties of the ecovata do not decrease over time, and in terms of insulation, it is not inferior to the mineral wool, foam concrete, wooden bars, brickwork and expanded clay;
• it does not cause corrosion. Ecowata is ideal for insulation of metal structures, since it does not provoke the formation of rust;
• it does not shrink. Due to the elasticity and elasticity of cellulose fibers, Ecowata over time does not shrink even in vertical structures. This is an incomparable advantage over cotton heaters;
• high -quality soundproofing. It is much higher than that of mineral wool. The layer of 5 cm thick is able to absorb the noise of 63 dB. Therefore, when it is insulated with all walls, floor and inter -story floors, excellent results can be achieved. But most often this material is used to warm the walls inside the house still at the construction stage;
• fast installation. Its spraying on the walls is carried out using a special vacuum cleaner. This method allows you to fill all the cracks and inaccessible places, creating a seamless coating. A professional will cope with the insulation of a house of 100 m2 in just 1-2 days;
• it has moisture resistant and vapor permeable properties. Ecowata is able to both accumulate and give moisture without losing its thermal insulation properties. But, despite the assurances of manufacturers in the absence of the need for a vapor barrier device, it should be done;
• bio resistance of the material. Due to the content of antiseptics in its composition, ecowata is resistant to microorganisms. So, successfully protects the walls from decay and destruction. The antiseptic is boric compounds that have a specific taste and are destructive for rodents and other pests;
• fire resistance. Ecowata is resistant to combustion, it smolders, but does not light up and does not melt. When the source of sunbathing is eliminated, it immediately goes out.

Flaws:

• despite the fact that the sprayer can be rented, installation should be entrusted to professionals, which leads to a rise in the cost of work. It is on the quality of execution that successful and long -term operation of the house will depend;
• ecowata cannot be laid near a chimney, a lit fireplace or a hot pipe. Under the influence of high temperature, the material begins to smolder;
• when warming with a wet method and with applying a thick layer, the drying process can take more than a day.

The total cost of wall insulation from the inside will be more expensive than mineral wool. But this is an justified overpayment, because once heating qualitatively, you can enjoy a warm house for many years.

Liquceramic thermal insulation of walls from the inside

This is a super -thin thermal insulation, which includes a number of vacuum microspheres, acrylic binding, anti -corrosion and antifungal additives. The result is a moisture -proof, elastic and resistant to negative external exposure to the composition.

Outwardly, a liquid -ceramic insulation resembles ordinary paint, which makes it possible to apply it to absolutely any surface with a brush, a spray gun or a roller. It is thanks to its versatility and easy application that liquid insulation is so popular during construction and repair work. And in its characteristics, it even exceeds polystyrene and mineral wool. A layer thickness of only 1 mm is equivalent to 50 mm mineral wool.

Liquid insulation is able to withstand temperatures from 60 to +250 degrees without changing its operational characteristics. It will not require additional work on hydro- and vapor barrier. The service life is 15-30 years.

Advantages:

• excellent adhesion with any material (wood, concrete, plastic, metal);
• protects the wall from moisture;
• easily applied;
• reducing the heat loss of a room of 1 mm layer increases the temperature of the wall by 3 degrees;
• ease of repair if necessary;
• environmental and safe for health;
• there are no shelters for pests;
• it is allowed to apply at a temperature of up to 20 degrees;
• the final cost of thermal insulation is similar to the cost of wall painting;
• does not increase the load on the walls.

Cork wallpapers as a heater for walls

This is environmentally friendly and safe material. They are simultaneously a heater for walls and a decorative coating. But, despite the assurances of manufacturers about good heat-insulating qualities, because of the thin layer they are not effective enough.

Polistyle wallpaper with thermal insulation properties

With their help, not only the walls are insulated from the inside, but also mask small surface defects. This method is most rational for insulation of apartments when it is not possible to establish thermal insulation outside. The wallpaper has a thickness of only 3, 6 or 10 mm, which means that they practically do not engage in living space. They are rolls with a width of 50 cm to 1 meter and 10 m long. They are glued to the walls like ordinary wallpaper, but on a special glue.

Properties of the material:

• polistyle wallpapers have excellent thermal insulation properties, 6 mm of the material equivalently with a brick wall 12.5 cm thick (in half a brick);
• provide sound insulation;
• high moisture resistance protects the walls from mold;
• there is no unpleasant odor.

Polystyrene wallpapers are safe for health, as they do not contain Freon and Butane. And the glued VSTS they create a solid structure to breaks. On their front side there is a paper layer on which it will not be difficult to glue decorative wallpapers. There is a more budget option, without a paper layer, it is suitable for non -residential premises.

The disadvantages include its combustibility. As well as the fact that when gluing the polystyrene of the walls of the room (as with any other internal insulation), the gear point is shifted towards the room.

The insulation of the walls indoors is a responsible work, the result of which should please for many years. If there are doubts about your own abilities, trust all calculations and the choice of thermal insulation material to professionals.
