The use of a reinforced mesh in the construction of a house significantly increases the resistance of a brick wall, monolithic concrete slab, aerated concrete, expanded clay concrete or u-block to loads both to external and internal elements. It combines all the elements of the wall into a single complex and serves as a kind of stiffener.
Simply put, the walls need to be reinforced, because if you do not use a reliable insulation layer, then cold air will get into the building in winter, and temperature fluctuations can lead to damage, that is, to their quick cracking, in the worst case, destruction. The process takes place from the outside during the construction of the house, but if this was not done on time, it is still worth doing it when the issue of facade repair work is completed.
Varieties of insulation
There are several options for insulating a reinforced belt. Let's consider each method in detail.
1. Armopoyas with jumpers
To complete this task, it is necessary to insulate, without protruding as a material between the metal mesh https://sitkazahid.com/en/catalog/armopoyas-grid/c288 and the wall. Experts recommend using extruded polystyrene foam with a thickness of 80 millimeters, since the foam sheets are thin and fragile, they will not be enough for dense insulation of the structure. Mineral wool is also used because it absorbs moisture between the insulating material and the case, but a ventilation gap is needed.
2. Equal to the width of the wall
Additional insulation materials are installed peripherally to achieve the height of the reinforced belt. For a two-story house, two insulating tapes are needed: one is located between the floors, and the other is under the Mauerlat under the roof. The heat insulator is installed at a distance of 15 cm from the belt line.
Briefly about the stages:
1. With a brush, remove dust, mortar from masonry from the foundation and thoroughly clean the surface.
2. Eliminate irregularities.
3. Priming the framework with a brush.
4. Install the timber plank formwork.
5. On the periphery of the windows, it is necessary to fasten the reinforcement mesh.
6. Stick the insulation on the mastic, and after drying, fix it.
7. Arrangement of drains in the upper part of the tape at a slope from the wall to drain rain, snow from the block with an armored belt.
8. Filling the floor beams with concrete.
As an analogue of external insulation, it is advised to use sprayed polyurethane foam, but this is a very expensive and toxic material. In addition, the installation requires special tools and the work of a professional craftsman.
3. If there is a gap
Open holes with professional foam with a gap of 25-30 cm through along the line of the armored belt. This method is considered one of the highest quality, and in addition, it reduces the consumption of materials.
Summing up, it can be argued that with correctly performed insulation with reinforced concrete armored belts https://sitkazahid.com/en/landing/armopoyas or reinforcement during construction work, in winter the wall, like a shield, will not let cold air through. This means that it will be better to keep warm.
