Insulation of the house from the outside: choose the best insulation

By what criteria to select a heater for the house outside

It's about suburban buildings: country houses, cottages, village houses, ie,of ensuring insulation of private buildings intended for permanent or seasonal residence.The first issue of "the better to insulate the house from the outside," arises in the construction of frame structures, but also houses of timber or brick also may need additional insulation.

Manufacturers offer a great variety of insulating materials, each of which has its obvious advantages and is not always openly advertised shortcomings.Perfect insulation construction of a private house: basement, facade walls, ceilings, cellar, in our opinion, should have the following properties.

• Fire safety .This criterion is often decisive for wooden houses.Easily flammable materials released during the combustion of hazardous chemical volatile compounds, to be used outside as insulation for walls with great care.
• Moisture .Keep in mind that even with high-quality steam and waterproofing layer of insulation work in conditions of high humidity.Hygroscopicity of fibrous and porous media must be taken into account when choosing a warming design.
• The share .The additional load on the base plates (rolls, blocks) of external insulation useless.Relief is usually achieved high porosity products, but immediately comes into conflict with the preceding paragraph.Look for a compromise.
• Easy installation.Ideally, house warming outside standard panels must be carried out with their hands - it's cost effective and guarantees the reliability of the thermal protection.
• low thermal conductivity coefficient .The main technical characteristics of any heat transfer medium.Based on it, we can estimate the allowable temperature differences on the outer and inner surfaces and choose the thickness of the insulation layer corresponding to the climatic conditions in your area.Typically, these data producers indicate in the passport of the goods.

Where necessary insulation outside the house?

first identify those places in your country estate, which require mandatory (desired) insulation.

• foundation (base) .Through non-insulated floor there is up to 30% of heat loss, increasing the impact of soil moisture;up: in the autumn-spring period in weekend house, we have a seasonal rapid destruction of the flooring, cold and damp room;
• wall insulation outside the house .Obvious advantages: domestic residential home footage is not reduced, and the correctly chosen insulation can be used as the basis of a rough finish;
• insulation of the roof and attic floors .Most of the household fumes inevitably extends into the attic and condense on the roof, so the moisture "top" of the thermal protection becomes a priority;
• basement, outbuildings, sauna .The subject of much discussion, review and assess which would have individually.Treat the temperature regime of the premises should be pragmatic.

Thermal insulation of any existing structural element, or even just designed buildings can be variably to work out if there is a time and money, or buy and install the same type of exterior insulation system for the entire building, according to their own ideas about the best material.

Usually people who have decided to make the outer insulation of the house, at the stage of selecting suitable materials for this purpose make a number of unforced errors.Blame, of course, advertising, and offers an abundance of our credulity.

better insulate the outside of your home country?

As we have said, any product advertised and promoted in retail chains under the brand name "insulation materials" has its advantages and disadvantages.Let us discuss them in the synopsis.

1. Mineral wool .This category usually include completely different production technologies, technical and chemical properties of fiber boards.In the modern version of laminated mats (rock, stone wool) has obvious positive side: the low thermal conductivity (0,032-0,046);top class A1 fire resistance (can withstand without ignition temperature up to 1000 degrees);ease of transportation and installation;flexibility, ease of cutting, the possibility of high-quality installation of insulation in the house with his own hands.And the negative: absorb water like a kitchen sponge, iecan work only in rooms with enhanced vapor barrier.Smart choice for interior insulation, but as a heater for the house from the outside it is better not to use.
   
2. Foamed plastics.The easiest and cheapest option - the panel of ordinary foam.New variations on the theme: polyurethane, polystyrene, etc. penoplex Pros:. Small share, the apparent ease of installation, high moisture resistance and low thermal conductivity.Cons: if not lit, highlights the mixture of volatile asphyxiating gases.Not strong enough for mounting on uneven wall surfaces.
   
3. fibrolitovye plate.For more information about these construction and finishing materials you can find on our site.We have this way of warming a country house outside the shell and core is the most advantageous from an economic (compared with sandwich - panels ) and the technological side.
