On what criteria to choose a heater for a house outside
It will be about suburban buildings: cottages, cottages, village houses, i.e.on providing insulation of private buildings intended for permanent or seasonal living. First of all, the question "what is the best way to warm the house from the outside" occurs when erecting frame structures, but houses made of timber or bricks may also need additional insulation.
Manufacturers offer a huge variety of thermal insulation materials, each with its obvious advantages and not always openly advertised flaws. The ideal insulation of the designs of a private house: the plinth, the facade walls, the ceiling slabs, the basement, in our opinion, should have the following properties.
- Fire safety .For wooden houses, this criterion is often decisive. Flammable materials, which emit dangerous chemical volatile compounds during combustion, should be used externally as a heat insulation material for walls with great care.
- Water resistance .It should be remembered that even with high-quality steam and waterproofing, the insulation layer works under conditions of high humidity. The hygroscopicity of fibrous and porous media must be taken into account when choosing a thermal insulation.
- Specific weight of .Additional load on the plinth of plates( rolls, blocks) of external insulation is useless. Relief is usually achieved by high porosity of products, but immediately contradicts the previous point. Look for a compromise.
- Easy installation .Ideally, the insulation of the house from the outside with standard panels must be carried out by oneself - this is economically profitable, and guarantees the reliability of thermal protection.
- Low specific conductivity coefficient .The main technical characteristics of any heat transfer medium. Proceeding from it, it is possible to estimate the permissible temperature differences on the external and internal surfaces and choose the thickness of the warming layer, corresponding to the climatic conditions of your region. Usually, these manufacturers indicate the data in the product passport.
Where is the insulation of the house from the outside?
First, we will identify with those places in your country estate that require mandatory( desired) thermal insulation.
- foundation( socle) .Through the unheated floor, up to 30% of heat loss occurs, reinforced by exposure to ground moisture;total: in the autumn-spring period in the holiday houses of seasonal use we have a rapid destruction of the flooring, cold and damp rooms;
- warming the walls of the house outside .Obvious advantages: the inner residential dwelling of the dwelling does not decrease, and the correctly chosen insulation can be used as a basis for rough finishing;
- roof and attic roof insulation .Most household fumes inevitably stretch to the attic and condense on the roof, so the moisture resistance of the "top" thermal protection becomes a priority;
- basement, outbuildings, sauna .The subject of a special discussion, which will have to be considered and evaluated separately. To concern to a temperature mode of these premises follows pragmatically.
Thermal insulation of any structural element of the existing or only a newly designed building can be worked out variably, if there is time and money, or buy and mount from outside a similar type of insulation system for the entire building, based on own ideas about the best material.
Usually people who decided to make outdoor insulation at home, already at the stage of choosing suitable for this construction materials make a number of unforced errors. Blame, of course, advertising, an abundance of suggestions and our trustfulness.
What is better to insulate outside your country house?
As we have already said, any products advertised and promoted in trade networks under the brand name "heat-insulating materials" have their advantages and disadvantages. We will discuss them in a brief review.
- Mineral wool .This category usually includes completely different in technology of production, technical and chemical properties of fibrous plates. In the modern design of layered mats( mineral, stone wool) there are obvious positive sides: low thermal conductivity( 0.032-0.046);fire resistance of high class А1( withstands without ignition temperature up to 1000 deg);Convenience of transportation and installation;elasticity, ease of cutting, the possibility of a quality installation of insulation in the house with their own hands. And the negative: absorb water as a kitchen sponge, i.e. Work can only in rooms with enhanced vapor barrier. A reasonable choice for internal insulation, but as a heater for a house outside it is better not to use it.
- Foamed plastics .The easiest and cheapest option - a panel of ordinary foam. New variations on the theme: polyurethane foam, polystyrene, foam foam, etc. Pros: small specific weight, apparent simplicity of installation, high moisture resistance and low coefficient of thermal conductivity. Cons: if it does not even burn, then it emits a mixture of suffocating volatile gases. Insufficiently strong for fixing to uneven wall surfaces.
- Fibrolite boards .Detailed information about these building and finishing materials can be found on the pages of our website. This way of warming a country house outside to a finish finish seems to be the most preferable from an economic one( compared to with sandwich panels) and the technological side.
