Materials for thermal insulation
The onset of the heating period quite significantly hits the pocket regardless of whether you have Central heating or Autonomous. Have you ever thought about the fact that some of the money you pay for the heating of the environment because of poor insulation, the heat goes out of the room? It is therefore very important to insulate your home. selecting the right materials for thermal insulation.
Materials for insulation are very different. Their choice depends primarily on how exactly you decide to insulate your home. For example, in private homes often make use of exterior insulation, insulated no interior walls and the façade. And the apartment is easier to insulate from the inside. You may need insulation in the attic. balcony. Finally, you can't insulate the whole apartment and all Windows, to avoid gaps in which to inject cold air or just the floor. And in each case will need different materials for insulation.
Materials for thermal insulation (thermal insulation) are divided into three main groups. Organic materials for thermal insulation produce with the use of organic substances. First of all, this is a variety of foams. Their essential flaw is one - a slight flammability. Also to organic heaters include recycled wood, fiberboard, particle board, peat and agricultural waste (reeds, straw).
Inorganic materials for thermal insulation - this is primarily mineral wool and products based on it, various types of light and cellular concrete (aerated concrete, foam concrete, gas foam concrete, foamed glass), fiberglass, expanded perlite, vermiculite, etc. The disadvantage of this group of insulation is low strength and increased water absorption.
Mixed insulation do on the basis of asbestos, a mixture of asbestos with mineral binders or expanded rock.
One of the most famous insulation is mineral wool. which, depending on the process used for its production material is divided into glass, stone and slag. This material has good heat and sound insulation, resistant to high temperatures and chemicals. It is used for outdoor insulation (including for wet facade ) and internal.
But mineral wool is not completely secure. different types of mineral fibers assigned different categories of danger to human health and animals. Therefore, many prefer mineral wool other materials for insulation, for example, expanded polystyrene.
Penopolistirol is a lightweight cellular phenoplasts based on polystyrene or its derivatives. It is produced by different technologies, therefore different brands of expanded polystyrene have different properties. But speaking in general, polystyrene foam is a fairly strong material for insulation with good thermal insulation properties. It is convenient to handle and cheap enough, therefore, expanded polystyrene is widely used for insulation of facades, both in pure form and in combination with other substances (say, the composition of the thermoplastic gypsum includes portland cement, lime and chemical regulators).
Polystyrene is resistant to moisture, chemicals and mold, durable. But polystyrene is a combustible flammable material. therefore in its structure often enter antipyrenes - it turns out so-called self-extinguishing expanded polystyrene. Fire retardants in the foam polystyrene help reduce the chance of accidental fire and reduce flammability. For insulation use both expanded and extruded polystyrene foam.
In addition to the expanded polystyrene used other materials for thermal insulation belonging to the class of foams (expanded gas-filled plastic). This polyurethane, and penopolyurethane and urea-formaldehyde foam (urea foam, penoizol). They differ in the degree of thermal protection, combustibility and other properties. As insulation glass wool is also used, advanced insulation based on polyester fibers, ecowool (cellulose insulation).
For floor insulation use mineral wool, expanded clay, cement mortars, particle board, sawdust, ecowool, plywood, plate heaters from foam and its derivatives, aluminum-foamed reflective materials based on polymers, foamed polymers, roll polymers, heat insulating paints (liquid polymer insulators), glass wool. And the windows are often warmed with banal foam.
As you can see, the range of heaters is very wide, different materials for insulation have different properties and have their own advantages and disadvantages. So in each case it is better to consult with a professional repair to choose the best insulation .
