About 30% of heat loss occurs through walls. To solve this problem, they should be warmed. Warming the facade mineral wool with their own hands - this is one of the options for thermal insulation. Mineral wool is produced from glass melts, slag or rocks, and resins are the binding element. The material has a fibrous structure, the direction of the fibers differs depending on the purpose of the mineral wool.
In this article, we will focus on the characteristics of mineral wool, technological features of wall insulation, features of thermal insulation of walls for siding and plaster. Knowledge will help you accomplish the task qualitatively, with minimal labor and time costs.
If you decide to warm the walls outside the mineral wool, then your choice is quite reasonable. Among the positive characteristics of the material is worth noting:
Mineral wool is of three types:
Basalt mineral wool is considered the most effective for thermal insulation of the facade of the house. The material has a low level of thermal conductivity. For the arrangement of the ventilated facade specialists have developed a special heterogeneous insulation.
Facade mineral wool differs from its counterpart, which is intended for wall insulation from the inside. Vata for the facade has a greater hydrophobicity or ability to repel moisture, in addition, it is more dense.
Facade mineral wool
As with any material, mineral wool has not only advantages but also disadvantages. However, if the technological processes are strictly followed, they can be eliminated. If mineral wool is not treated with hydrophobic compounds, then it will absorb moisture, and this will lead to loss of the insulating properties of the material. If you do not install a reinforcing layer, the facade may crack.
Warming the house outside will help you keep warm and, of course, reduce heat loss. The progress of all work can be divided into the following stages:
The facade needs to be prepared
If you properly prepare the walls before warming the facade with mineral wool then the whole workflow will take you less time, and the result will be much better. So, for a start, clean the facade of cement spills, protrusions and metal pins protruding from the walls. Then remove all communications, such as drain pipes, brackets, wires and other items.
If metal fasteners are left in the wall, they will rust due to temperature fluctuations and condensate over time. Subsequently, over time, red spots will certainly appear on the facade cladding.
If there are cracks and chips on the walls, seal them with a mortar. Then apply an anti-fungal coating to the entire surface of the walls. This event is important to do, even if there are no visible signs of mold on the walls. Such prophylaxis will prevent the appearance of fungus on the surface, especially if it is under constant exposure to moisture. If the walls of your house are made of wood, then impregnate them with antiseptic.
Minvata is made of basalt in slabs. Its dimensions are 0.6 * 1.2 m and 0.5 * 1 m, and the thickness ranges from 5 to 15 cm. Experts recommend using material having a thickness of 10 cm.
The technology of thermal insulation of facades with mineral wool consists of several stages starting with the primer of the walls and finishing with reinforcement and finishing.
Insulation under siding
When finishing the walls siding, in most cases, arrange ventilated facade. Thus, the condensate evaporates unhindered. The vapor barrier film is fixed either with staples or liquid nails - it all depends on the wall material. In the next step, fix the vertical profile at a distance of 45-50 cm from each other. In between is placed the mineral wool. Insulation can additionally be fixed with dowels.
Double insulation under siding
From above, the mineral wool is covered with a waterproofing membrane, the joints of which are taped with butyl tape . This is a mandatory step, as mineral wool is sensitive to moisture. Then install the contra-grill, on which the siding is subsequently installed.
Wet facade insulation scheme
In fact, when performing warming of the facade of the mineral wool, you should not face problems. With the observance of technology, you can complete the work quickly and efficiently. Mineral wool is a material that will allow you to insulate a house, protect it from temperature drops, having done so in the shortest possible time and at a reasonable price.
