The wide choice of materials for warming of facades is presented at the market, choosing, be guided by the most important characteristics - heat conductivity, density. Thermal insulation can be combined, it is not obligatory that all walls of the house had the equal thickness of heater, from South side, the sun provides bigger receipt of heat, than from the North.
Warming of own house is not whim, but reasonable need. Concrete, or brick walls of the building even if they are only exterior finish of the warmed panel board framework, will not be able to stop the penetrating wind, hard frost. Here in such cases special materials for warming of facades of buildings also come to the rescue.
Characteristics of heaters
All construction materials intended for warming of front surface of walls of buildings have special characteristics. Relying on their knowledge, it is possible to pick up the necessary heater accepted in specific case:
1. The most important property – heat conductivity. The less than its coefficient, the more guarantee that heat will not leave the house, changing cozy and comfortable microclimate for subarctic zone. 2. Stability level to the moisture which is contained in the atmosphere shows water absorption coefficient. The lower it value, the less material it is subject to soaking or absorption of moisture. 3. Density directly affects heat-exchanging characteristics of heater, however, it increases the weight of all thermoinsulating design. This parameter needs to be considered as excessive load of supporters of the building can lead to unpredictable consequences (clinking in walls, shrinkage or destruction of the base, etc.).4. And, of course, combustibility of these materials – one of key parameters which need to pay special attention. Especially, if carrying out electrical wiring directly under heat-insulation layer is planned.
Types of heaters
For warming of facades of buildings, the base, overlappings the following types of the heatpreserving materials are used: glass wool, mineral wool, expanded polystyrene and extruded polystyrene foam. Glass wool is kind of mineral wool. If mineral wool is made of the processed slags or silicates, then glass wool is produced from waste of stekloproizvodstvo. Both types of heater are presented in the form of rolls or tiles. They can have various density and thickness.
Glass wool and the minvat are absolutely non-combustible materials. At the same time they are capable to absorb moisture actively. For creation of impervious layer when finishing the special film is in addition used.
Mineral and glass wool are excellent gobo and well will be suitable for finishing of the buildings which are near sources of strong noise (highway, the railway station, etc.). The system of Rockwool - example of mineral heater which besides positively influences the environment. Choosing specific type of rokvul for facade, it is necessary to consider way of final finishing, so, if plaster is planned, then depending on its thickness, it is possible to consider, for example, such options - BATTS FACADE (for thin plaster coat), PLASTER BATTS (for thick plaster coat), VENTI BATTS (for the ventilated facades). Expanded polystyrene and extruded polystyrene foam - that other, as the plastic which is made foam by gas. As these materials are simply penetrated by air bells, they are very easy on weight. These materials have the minimum coefficient of thermal conductivity, and thanks to the closed structure of air cells also perfectly detain moisture. Though the foam heaters use also for noise isolation of buildings, they considerably concede in this quality to cotton materials. Besides expanded polystyrene is subject to burning process that creates need to consider consequences at fire emergence.
There are various degrees of combustibility characterizing separate types of polyfoams. Some of them can burn only if nearby there is source of constant fire.
Works on warming of facade do not represent special complexity with certain skills. All stages are simple, do not demand availability of special purpose tools and the equipment. Of course, if the guaranteed quality is required, it is better to ask for the help experts.
