The market of materials for private housing construction is constantly replenished. Among the product range you can find: cellular concrete, profiled timber and brick. These are the most common solutions, but for private housing construction today it is customary to use more modern options.
Modern building solution
This list is not complete. It can be supplemented with sandwich panels, which help in solving the problem when it comes to building a house easily, quickly and economically. This technology is relatively new. She quickly gained popularity in a short time.
Description of houses
A house made of metal sandwich panels is a building, the walls of which are built from products produced in the factory. It uses high performance equipment. Such panels consist of three layers and are a kind of sandwich.
There is a layer of insulation between the two outer sheets. The thicker and better it is, the more comfortable the conditions in the house will be. There may be different materials inside, for example:
- polyurethane foam;
- mineral wool;
- styrofoam;
- fiberglass.
Varieties of panels
Depending on where the sandwich panels will be used, they can be roofing or wall. The latter are divided into simple profiled, smooth or decorative profiled. Roof panels can be profiled on one or both sides. For private housing construction, the latter option is rarely used, because inside the house the walls have yet to be finished.
Selection of the best panels
Houses made of metal sandwich panels have different characteristics depending on what is at the base of the walls. If you want to build a building with outstanding characteristics, then you should take the choice of material more seriously. An important factor in this case is the type of insulation. For example, expanded polystyrene is durable and environmentally friendly, which does not allow moisture to pass through, and also retains heat well. Among its shortcomings, fire hazard should be highlighted.
Polyurethane foam has the lowest thermal conductivity, is resistant to chemicals and has excellent waterproofing properties. Mineral wool can also be located inside, it is not combustible, it is characterized by environmental friendliness and safety. Among other things, it retains heat well. The disadvantage is the low resistance to water, so the walls will require additional waterproofing.
A house made of metal sandwich panels can be warmer if you choose the right thickness of the products. An increase in thickness can lead to an increase in thermal insulation properties, but will also help to reduce the usable area. By choosing thicker panels, you may encounter installation difficulties, in addition, you will have to pay a higher cost for the material. In view of this, you must optimally calculate the thickness of the panels.
Before you start building a house from metal sandwich panels, you also need to pay attention to the manufacturer. On the Russian market, you can find sandwich panels from about 200 manufacturing companies. The largest are:
- Ruukki-Ventall;
- Electrical Shield;
- Mosstroy-31;
- KZLK;
- Termosteps-MTL;
- Trimo-VSK.
Features
Metal sandwich panels for home construction have the main features, among which:
- length;
- width;
- weight;
- thickness;
- soundproofing;
- fire resistance;
- bearing capacity;
- thermal resistance.
The specification depends on the length and width. If you choose the right dimensions, you can avoid excess and unnecessaryscraps. Wall panels can have a width of 1000 and 1200 mm. The length can be any and varies from 500 to 13500 mm. If you want to build a house from metal sandwich panels with your own hands, then you will need to determine the weight of the structure, which affects the need to build a deep or shallow foundation.
The weight of products depends on the type and thickness of the insulation. For example, rock wool panels are heavier than those with styrofoam inside. If polystyrene foam is used with a thickness of 50 mm, then a square meter of wall panel will weigh 11.7 kg. For mineral wool, this value is 16.5 kg per square meter. If the thickness of the expanded polystyrene is increased to 120 mm, the weight per square meter of the panel becomes 12.8 kg. For mineral wool, this figure is 24 kg per square meter.
With a maximum thickness of EPS of 250 mm, the weight of the panel becomes 14.7 kg per square meter. When using mineral wool inside the sandwich, the mass of one square meter is 38.5 kg. Residential buildings made of metal sandwich panels are subject to stringent requirements for thermal resistance, thermal conductivity, sound insulation, flammability, and fire resistance. All these indicators differ for different materials in the base.
The thickness indicator is also important. If 50mm mineral wool is used in the production process, the thermal resistance will be 1.04 Rt=m2×°C/W. Thermal conductivity will be equal to 0.05 λ=W/Mk. As for sound insulation, it will be relevant for the stovean indicator of 30 dB. The material is not combustible, its fire resistance limit according to GOST 30247.0-94 is EI 30. Density can vary from 105 to 140 kg per cubic meter. In 2 hours, water absorption will be 1.5% by weight.
Looking at photos of houses made of metal sandwich panels, you can understand that this material at the base of the walls suits you perfectly. However, this is not enough to decide whether to use such products for construction. It is also important to pay attention to the characteristics. If it is based on mineral wool, the thickness of which is 250 mm, then the sound insulation of the walls will be 43 dB. The thermal resistance in this case is 5.21 Rt=m2×°C/W. The thermal conductivity remains the same. But the fire resistance limit is EI 150. The density remains the same.
Positive reviews of panel houses
After reading reviews of houses made of metal sandwich panels, you may decide that you will use this material to build your home. Among the positive features, consumers highlight:
- possibility of construction in any season;
- lightweight panels;
- low construction cost;
- good performance of heat and sound insulation;
- low wall thickness;
- high speed work;
- evenness and strength of the walls.
Customers love that products havesmall thickness, in view of this, the usable area of \u200b\u200bthe house can be increased. The panels are lightweight, so when building a house, you can get by with a lightweight foundation. According to home masters, this reduces costs.
A house made of industrial metal sandwich panels is durable, it does not deform or shrink. This suggests that repair work can be carried out immediately after construction.
Negative reviews
Having considered the projects of houses from metal sandwich panels, you should not make hasty decisions. Before buying the material, you should also read the negative reviews. From them, you can learn what consumers believe: the material is short-lived compared to traditional concrete, wood or brick. In view of this, you should not count on the fact that the house will stand idle for more than 30 years. You can hear from manufacturers that they give a guarantee for 50 years, but this is hardly relevant for a harsh climate.
Buyers also emphasize that sandwich panels have unsatisfactory environmental friendliness. The walls will not breathe, because of this, the issue of competent ventilation is very acute. Buyers emphasize that such houses cope well with hurricane winds, but a fallen tree can make a hole in the wall. The material is not able to resist open fire for a long time, and when exposed to it, it begins to release harmful substances.
If you do not provide the house with an efficient ventilation system, then conditions will be created inside for the developmentmold and fungus, which negatively affects the well-being of residents. Consumers quite often refuse sandwich panels for the reason that they believe that it can be quite problematic to sell such a house after several years of operation. If this can be done, then the price will be lower compared to the building that was built of brick.
Construction Features
Before you start building a house, you should seek help from specialists. They may advise that it is not recommended to use only SIP panels in the process of work. For example, the floor can be made of wood, because in this case it will be easier to repair it.
As for the roof, it should be raftered, which will be easier than if you equip the roof with panels. During the construction of walls, it is important to observe the vertical. If the first two panels are set at an angle, the house will follow the slope.
In closing
SIP panels are a fairly standard material today. Although he entered the Russian market relatively recently, he managed to win the love of consumers. It is due to several factors. Among others, ease of construction and low cost of work should be highlighted.
