Insulation for walls : how best to choose

catastrophic shortage of energy resources and their high cost led to the development of various types of energy-saving technologies. in their desire to save the world population has reached incredible heights, and the slogan "insulated as you can!" Was taken literally by virtually all intelligent representatives of the human race.

One of the most common ways to reduce the use of natural resources was the wall insulation.To do this, use different materials and technologies, which we'll talk today on the site "House of Dreams", to study in detail all of their types and usage, as well as choosing the best insulation for walls.

Types of insulation for walls

Conventionally, all kinds of insulation for walls, allowing to perform high-quality thermal insulation of buildings can be divided into internal and external materials.They differ from each other by the ability to water vapor permeability - if the internal insulation of walls can be used exclusively permeable insulation, then here is for outdoor works successfully used both of them.

materials for external insulation of walls

External insulation for walls of the house are different from internal and other requirements - as a rule, the process of building insulation combined with decorated facade.This, in some cases requires sufficient material strength.How is the best answer to all these needs or foam polystyrene, basalt slab and a variety of warm plaster.But first things first, and begin to foam.

• Styrofoam or polystyrene .This outer insulation for the walls can be described as the most common - its performance can not only execute a complete home insulation, but also decorate the facade with decorative plaster.Wall insulation foam is by far the cheapest.As a rule, thermal and acoustic insulation of houses used foam thickness not less than 50mm - in its thermal conductivity such building protection equivalent to the thickness of the brickwork in a half-brick.Styrofoam or polystyrene is glued to the wall of the house, additionally mounted "umbrellas", after which the reinforcing mesh and plastered with a thin layer.After drying, a reinforcing layer on the surface of the walls decorative plaster applied.

• Basalt heat insulation material for the walls .Unlike foam, basalt slab can be used both for external and for internal insulation.Basalt heat insulation material for the walls have low thermal conductivity and high density.It can be mounted in different ways - in one case it is glued (as foam) followed by a reinforcement and finished with decorative plaster, in another case, it lay for ventilated façade, for example, under the siding.If we are talking about the use of basalt slabs as internal insulation for walls, it lay for plasterboard paneling.

• Warm plaster .Among the positive qualities of the material for the insulation of walls can be noted the high strength of the surface, which, in contrast to previous materials, it is very difficult to damage anything.In fact, the material for insulating plaster is nothing more than a conventional cement-sand mortar or with the addition of various natural and polymeric fillers that reduce the thermal conductivity of the initial composition.The thermal conductivity of the walls decorated with such a solution depends on the fillers used and their number - the result is simply excellent in some cases.A thin layer of thick 1-1,5sm able to replace pyatidesyatimillimetrovy foam.

material for internal insulation of walls

As mentioned above, must be used exclusively permeable materials indoors.These include mineral wool insulation for walls and natural (eg, cork wallpaper).

• Mineral wool .This material is the most common and is used for internal insulation of walls almost everywhere.The disadvantage of this method of insulation of buildings is a need to create a plastic sheathing or gypsum, which usually takes the lion's share of the room space.Its high performance of mineral wool insulation as shown in the wall frame house - in this case it can be embedded into the wall and does not steal any space.

Mineral wool can be produced in two ways - it is made either as separate plates of a relatively small size, or in rolls.Assigning them one thing, but there are different types of mineral wool according to the installation conditions in different ways.For example, rolled insulation, wall insulation is useful when large areas, and the same material made in the form of plates, great for work with small rooms.By and large, the difference between them is no no - the same roll can be cut into the necessary parts ordinary knife.

• Cork wallpaper .Their advantage is not only environmentally friendly, but also in flexibility - they both serve and insulation for walls, and decorative trim.Although manufacturers claim that the plug is an excellent insulator, yet because of a thin layer of thermal insulation properties of the material is poor.

Alternative wall insulation

Construction of new houses are already taking into account the energy-saving technologies and the additional insulation such houses usually do not need.

Make constructed walls warm a variety of ways, but the most common option is the installation of a brick wall with insulation.

creates a kind of layered cake - outside of the building fit with decorative brick, followed by a layer of foam or arranged basalt insulation and the outside structure of brick masonry performed poorer quality.She subsequently plastered, puttied and covered with decorative material.A distinctive feature of the thermal insulation of walls is no need for decorating the facade.

Among these methods create a warm wall meets their construction of the foam blocks.The shape and design, they resemble a cinder block, the cavity is reinforced and filled with concrete.Thus obtained solid to withstand heavy loads and, simultaneously, the warm walls of the house.

So in conclusion of this topic, which will allow you to choose the best insulation, I want to focus on the so-called liquid insulation for the walls.These include a liquid foam and the same ceramic insulation.In principle, these technologies are quite effective, but not suitable for self home insulation - special equipment is required for their application.

In general, however, and buy high-quality insulation for the walls of today there is no difficulty.It is much more difficult to determine the right with his choice and not to be mistaken with insulating properties.And most importantly, if you are going to carry out an independent insulation, then pay attention to the convenience and ease of use with this material.
