«My house - my fortress" - today, 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 are far from energy-saving technologies.Corner apartments, apartments on the ground floor of a long time generally considered cold.Moisture, cold, dust enter the apartment through cracks, joints and even interpanel wall.To avoid all this and secure a comfortable living conditions, sooner or later you have to think about warming your home.Only in this case it can be called its "fortress".
market range of thermal insulation materials ↑
In today's market of construction materials presented different types of insulation for the walls.Before proceeding to the execution of these works, you need to decide what is best for the insulation of walls, and which - for the floor, the better to warm the balcony, and that is most suitable for the dwelling.The correct choice of insulation will provide heat in winter and cool in summer.This is achieved by reducing heat loss and eliminate drafts.Also in the room is not properly insulated to dampness and mold, and the climate is healthy.If you want to buy insulation for walls, remember about such properties that it must meet:
- low thermal conductivity;
- environmental security;
choosing insulation, wall insulation or inside the wall outside, should take into account the material from which the house is built, how many floors it in any climate zone you live.
For insulation for the walls and frame house insulation 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 insulating walls are organic and inorganic.The first group includes cellulosic fiber, wood, rubber, cork, felt, moss, jute or hemp.Fibre (glass mineral wool) or cellular (expanded polystyrene, polyurethane foam, etc. Penoizol.) Heaters, liquid ceramics - are inorganic materials.Organic have a higher ecological safety, but they are not as functional and durable as not giving mold and mildew polystyrene and polyurethane foam.Development and testing in the industry continues, and there are new types of insulation for the walls.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 walls, their advantages and disadvantages.
Mineral wool: the pros and cons ↑
Mineral wool - one of the most common 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 the premises, both inside and outside.
Thermal insulation properties of the material are provided thanks 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 process is quite troublesome.On the one hand - well transfer plate deformation, on the other - it is necessary to use individual protective equipment for obepecheniya safety.
thickness of the material when used indoors narrows the existing space, which is undoubtedly negative.Water permeability of rock wool may lead to the fact that over time it will get wet from condensation, it will mold and fungus.This will reduce the heat conductivity.To avoid this from happening, you need to further seal the material.
technical properties of glass wool ↑
Glass wool - too fibrous insulation, the most tested 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 waste glass production.Producing it in plates and coils, and for transporting compressed.
thin, sharp and brittle glass fibers dangerous as by direct contact or by inhalation of air from glass fragments.Therefore, using it for insulation, it is important to provide themselves with goggles, respirator, gloves.Manufacturers of this material argue that modern types of glass are safe for humans.
Glass wool 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.
Features cellulose insulation ↑
This is one of the new materials for insulation, it has thermal insulation properties, environmental friendliness, functionality.It produces the insulation from the remnants of pulp production.It is used for external insulation and insulation for apartments inside - it is blown under the drywall, magnesite slabs or other. Materials.
Cellulose insulation breathable, which is its positive side.Worse, it is water-permeable, likely to be infected with fungus and mold, pozharonebezopasen.To get rid of these drawbacks, cellulose-based preservatives are added to enhance biopersistence and flame retardants for reducing the flammability.
advantages of expanded polystyrene (styrofoam) ↑
Expanded polystyrene is produced by foaming polystyrene 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 can replace 1.7 m brick walls, wooden wall of 25 cm or 9 cm mineral wool.
Styrofoam - is the best insulation for walls.Release it to the plates, which are.used for heat insulation of both the interior walls, balconies, attics and facades.Expanded polystyrene, because of its strength is not peculiar to sag.This is one of the cheapest materials for thermal insulation of the walls.Extruded polystyrene
In order to obtain such a material, polystyrene pellets are melted at a 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 wall covering (plaster, concrete, bricks).When it is completely compatible with organic resins and solvents.
Durable fiberboard insulation ↑
Fibrolite get after prosushat Xpress and wood chips, mixing them with a binder.They can be a portland cement or Mg salt.The thus obtained slabs made of natural material and the protective layer prevents the biological effect (fungus, mold, insects) and waterproofness.To make it a little longer retain their insulating properties, it will need an additional waterproofing.If the moisture content exceeds 35%, the material sooner or later begins to deteriorate.It enhances the durability of the material it further plastering.Fiberboard used for thermal insulation of internal walls, partitions and ceilings.It is easy to process and assemble.It is convenient to handle and mount tools because of its strength.
Eco-friendly cork materials ↑
Cork panel - one of the most eco-friendly materials for insulation.The material consists of tiny cells (40 million. 1 cu. Cm).The material thus possesses the strength and air permeability, and an appropriate (low) thermal conductivity.
material for thermal insulation produced by granulating raw material, heating it to 400 ° C and compressing into blocks.Their thickness may be 10-320 mm.
These panels of cork lightweight, resistant to mechanical stress, are not subject to shrinkage.The material is very durable and functional.It is also anti-noise room.His 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.
has cork and bioactivity: rot, mold and parasites she was not afraid.In case of fire it does not emit harmful substances.But not cheap.This is one of the most expensive heaters.
liquid ceramic insulation ↑
topical for insulating buildings becomes liquid insulation for walls.This is the tool of a new generation.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 is applied on clean brick, concrete, wood, metal, cardboard or plastic surface.Colour material - gray or white.
This keramoizolyatsiya easy to apply, it is safe, non-flammable, does not reduce the size of the room.Such insulation everything else air- and watertight.Once it dries, it forms an elastic wall coating.Thin walls made of brick to be treated for at least 5-6 times.This material, though not cheap (the flow rate of 1 -1 LDF layer 4 sq.), But it will last a very long time.On the insulation will have to forget for a quarter century.So the manufacturer promises.
Warming liquid foam ↑
Another embodiment of the liquid insulation - foam casting, called Penoizol.It poured from a hose between the walls, in cracks, formwork during construction.And this option is warming almost 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 his lifetime - up to 50 years.
Video: recommendations choosing insulation ↑
Huge selection of insulation for walls sometimes perplexed those who want to live in the warmth.Some prefer the old and proven glass wool, not trusting new materials, others use only the advanced technology.But it is important, knowing the useful properties of all materials, use them skillfully combining.Walls are insulated with mineral wool or foam, to remote places to fill Penoizol, and a small area under the windowsill process liquid ceramics.
