Overview of heaters: a better insulation for walls, comparing the technical and technological characteristics

Overview of heaters

"My home - my castle" - to date,Unfortunately, this can not be said about our accommodation. When built most of the housing stock, no one thought about how to keep warm, and even more savings. It turns out that our "Stalinka", "brezhnevki", "Gym shoes" and all the rest of the housing far from energy-saving technologies. Corner apartments, apartments on the ground and upper floors for a long time generally considered cold. Moisture, cold, dust enter the apartment through cracks, joints and even the bulkhead wall. To avoid all this and secure a comfortable living conditions, we must sooner or later think about the insulation of their homes. Only in this case it can be called its "fortress".

Market range of thermal insulation materials

In today's market presents different kinds of building materials insulation for walls. Before you begin to perform these works, you need to decide what kind of insulation is better for the walls, and what - for the floor, the better warm balconyAnd what is the most suitable for living quarters. The right choice of heater will provide heat in winter and cool in summer. This is achieved by reducing heat loss and eliminate drafts. Also in the room properly insulated will not be damp and mold and micro-climate is healthy. If you want to buy insulation for walls, remember about these properties, he must comply with:

  • low thermal conductivity;
  • soundproofing;
  • fire;
  • environmental Safety;
  • durability;
  • water resistant;
  • breathability;
  • biostability.

Choosing insulation for walls inside or outside insulation for walls, necessary to consider the material from which the house is built, how many floors it, in what climate zone you live.

Thus, insulation for the walls and frame houseinsulation for walls of wooden houses (mezhventsovogo) - it's not the same thing. In the first case suitable foam, mineral wool, glass wool, Penoizol, in the second - the usual hemp, jute, flax felt.

Materials for warming of walls are organicand inorganic. The first group includes cellulose fiber, wood, rubber, cork, felt, moss, jute or hemp. The fiber (glass wool, mineral wool) or cellular (expanded polystyrene, polyurethane foam, etc. Penoizol.) Heaters, liquid ceramics - are inorganic materials. The organic have a higher ecological safety, but they are not as functional and durable as not amenable to fungus and mold expanded polystyrene and polyurethane foam. Development and testing of new types of insulation for the walls and continued there in the industry. Thus, the increasing popularity won the liquid insulation for walls. Let's look at what are the different kinds of materials for thermal insulation of the walls, their advantages and disadvantages.

Mineral wool: pros and cons

Wall insulation with mineral wool

Wall insulation with mineral wool with a frame structure of metal profiles

Mineral wool - one of the mostcommon fiber insulating materials. Mineral wool is produced by heat treatment and pressing metallurgical slag or basalt. The fibrous structure retains a air, thereby forming a barrier to the penetration of cold and heat loss. Mineral wool is in the form of plates and continuous web into rolls. It is used for thermal insulation of buildings, both inside and outside.

Thermal insulation properties of the materialprovided due to its low thermal conductivity. The advantage of this material ensures its breathability, durability, sound insulation properties, fire resistance, environmental friendliness.

Installation of the insulation is quite troublesome process. On the one hand - plate deformation is well tolerated, with another - you need to use individual means of protection for obepecheniya safety.

The thickness of the material when used inIt narrows the space existing space, which is undoubtedly negative. Water permeability of rock wool may lead to the fact that with time it gets wet by condensation, it will mold and fungus. This will reduce the thermal conductivity. To avoid this from happening, you need to further seal the material.

Technical properties of glass

Glass wool for insulation of walls

Outdated wool to insulate the walls of residential buildings are now used rarely

Glass wool - too fibrous insulation, the mostchecked out of all, as is used for thermal insulation for a long time. It is formed by melting glass wool sand, soda ash, dolomite, limestone, borax or glass waste. Releasing it into slabs and rolls, and compressed for transportation.

The thin, sharp and brittle glass fiberdangerous as by direct contact or by inhalation of air from the glass fragments. Therefore, using it for insulation, it is important to provide themselves with goggles, respirator, gloves. Manufacturers claim that the material that modern types of glass are safe for humans.

Fiberglass does not burn. It has good heat and sound insulating properties. It can be used for thermal insulation of all types of roofs, interior walls and exterior walls. It is cheaper than most of the insulation, but more amenable to shrink and crumble.

Characteristics of cellulose insulation

Wall insulation cellulose

Cellulose insulation of walls can be made, both outside and inside

This is one of the new materials forinsulation, it has insulating properties, environmental friendliness, functionality. Made of cellulose insulation is a production residue. It is used for external insulation and insulation for apartments inside - it is blown under the drywall, magnesite boards or other materials..

Cellulose insulation breathable thatit is the positive side. Worse, it is permeable, is subject to contamination by fungus and mold, pozharonebezopasen. To get rid of these drawbacks, a cellulose base is added to raise biopersistence antiseptics and flame retardants for reducing the flammability.

Advantages of styrofoam (foam)

Wall, insulated foam

Wall, insulated foam will provide a significant reduction of heat loss

Expanded polystyrene is produced by foamingpolystyrene at high temperatures. It is a white rustling material, which is characterized by water and air tightness, noise and thermal insulation properties, light weight, ease of installation. He is not afraid of bacteria, fungi and mold, it is not afraid of bad weather conditions. Just 8 cm polystyrene able to replace 1.7m brick walls, wooden wall of 25 cm or 9 cm mineral wool.

Expanded polystyrene - it is the best insulation for walls. Producing it in the plates, which are. used for thermal insulation as the interior walls, balconies, attics and facades of houses. Expanded polystyrene, because of its strength does not tend to sag. This is one of the cheapest materials to insulate the walls.

Extruded polystyrene foam

In order to obtain such a material, the granulespolystyrene melt at high temperature, then the material is extruded from the extruder and foamed. It turns out even more rugged, durable, airtight and waterproof than foam. Material good contacts with different coatings of walls (plaster, concrete, brick). When it is completely compatible with organic resins and solvents.

Durable fiberboard insulation

Installation of insulation fiberboard

Fiberboard wall insulated from the inside, the installation slabs require laying a waterproofing layer and plaster

Fiberboard obtained after prosushat andXpress wood chips, mixing them with a binder. They can be a portland cement or magnesia salt. The thus obtained slabs made of natural material and the protective layer prevents the biological effect (fungus, mold, insects) and watertightness. To make it a little longer retain their insulating properties, it will need an additional waterproofing. If the moisture content exceeds 35%, the material will start to deteriorate sooner or later. It enhances the durability of the material it additional plastering. Fiberboard used for thermal insulation of internal walls, partitions and ceilings. It is easy in handling and installation. It is convenient to handle and mount tools because of its strength.

Eco-friendly cork materials

Cork insulation for walls

Cork insulation for walls - not cheap, but the best long-term option

Cork panel - one of the most environmentally friendlymaterials for thermal insulation. The material consists of tiny cells (40 million. Per 1 cu. Cm). Thus the material has both strength and air permeability, and an appropriate (low) thermal conductivity.

The material for the insulation are produced by granulation of raw materials, heating it to 400 ° C and compressing into blocks. its thickness may be 10-320 mm.

These panels of cork light,resistant to mechanical stress, is not subjected to shrinkage. The material is very durable and functional. It is also anti-noise room. And its appearance makes it suitable even for decoration. Thus it is possible and to provide thermal insulation, and not to hide behind the cork frames and plasterboard.

It has plug and bioactivity: rot, mold and vermin are not afraid of it. In case of fire it does not emit harmful substances. But not cheap. This is one of the most expensive insulation.

Liquid ceramic insulation

The wall, insulated from the outside of the liquid ceramic insulation

Urgent for insulating buildings becomesliquid insulation for walls. This is the new generation tool. They can insulate both internal and external parts of the premises. Even in the most remote places, the liquid ceramic will help get rid of drafts and heat loss. The pasty slurry consists of closed areas, applied on clean brick, concrete, wood, metal, cardboard or plastic surface. Color material - gray or white.

This keramoizolyatsiya easy to apply, itsafe, non-flammable, does not reduce the size of the room. Such insulation everything else air- and watertight. Once it is dry, flexible coating is formed on the wall. Thin walls made of brick to be treated for at least 5-6 times. This material, though not cheap (its consumption for 1 layer -1 LAD 4 sq.), But it will last a very long time. On the insulation will have to forget for a quarter century. So manufacturers promise.

Warming liquid foam

Another option is liquid insulation - castingfoam called Penoizol. It is poured between the walls of the pipes, in the gap, the formwork during the construction process. And this option is warming almost in 2 times cheaper than all the others. But the main indicators that are important for insulation, he observes. It is resistant to bio-organisms, breathable, poorly lit, durable. Its insulating properties to 8% better than that of the foam, and 12% - than in glass. But its service life - up to 50 years.

Huge selection of insulation for walls sometimesperplexed those who want to live in the warmth. Some prefer the old proven and glass wool, not trusting the new materials, others use very advanced technology. But it is important, knowing the useful properties of all materials, use them skillfully combining. The walls insulate foam or mineral wool, in remote places pour Penoizol, and a small area under the windowsill process liquid ceramics.
