One of the wishes for the future home is that the house be built inexpensively and efficiently. However, in recent years, another important requirement has been added to these requirements - that the house be built quickly. And it is dictated not only by the ever-increasing pace of life, but also by today: people cannot spend a year or two building and finishing a house. Often, after selling an apartment, you need to quickly build a house and move into it. A stretching of construction in time is associated, as a rule, with additional costs, in particular, and for the removal of housing. All these problems are avoided by the technology of building houses from SIP panels.
To prepare this material, we turned not only to market experts, but also talked with the owners of houses built of CIP panels, as well as with visitors who are only considering this technology. Surveys at the exhibition show that approximately every tenth comes to the exhibition "Low-Rise Country" just behind the house built of CIP panels.
Such an approach will allow us to reveal the advantages and to dispel the myths that have already formed around the CIP panels.
When it comes to choosing a construction technology, the advantages of a particular construction method are first of all evaluated in order to understand how much they can outweigh the disadvantages.
According to various estimates, the price of a house from CIP panels is three times lower than from a brick. And 10-15% more expensive than a similar frame house, subject to the assembly of the house at the construction site.
When ordering a house from CIP panels, it is easier to control the consumption of material and the work of builders. Unscrupulous builders more difficult to cheat prices.
As one owner of the CIP-panels said : "The speed of construction of the house allowed me to change the apartment to the house without attracting additional funds, according to the principle" I sold one thing - I bought another one ".
And this is true. Calculation of heat loss of a single-storey house 10 * 10 m with a wall thickness (insulation) of 150 mm, at an indoor temperature of plus 18 degrees, and outside - minus 25 indicates that this value is 3.91 kW / h for mineral foam polystyrene filler, mineral wool - 4.3 kW / h, coniferous beams - 9.21 kW / h, log cabin - 12.27 kW / h, foam concrete - 16.74 kW / h, bricks - 27.45 kW / h.
And this means that the finishing work of such walls will be as simple as possible, since the walls in the house are made of CIP panels.
The CIP panels do not shrink. This allows you to start finishing the house immediately after its construction. And enter the house as soon as possible - in one - three months after construction.
As they say, those who live in such houses: “Having a house of CIP panels, we think, is it worth it to carry out the gas?”
Special attention should be paid to the quality of the design and installation of ventilation. If these works are done poorly, then just the ventilation will become the main source of heat loss, plus the installation will not be able to provide a given microclimate inside the house.
A house from CIP panels can be erected at any time of the year. However, it is desirable that during the construction of the house there was no precipitation - both rain and snow. From precipitation, one should cover both erected walls and unused panels.
. Ease affects the ease of installation: no need to order an additional crane for loading / unloading, installing / laying of SIP-panels. Plates are installed manually. A standard slab with dimensions of 2500 * 1250 * 174 mm weighs about 50 kg.
It should be noted that the set of SIP panels for a house of 170 square meters. m will weigh about 15 tons, and a brick for the same house - 60 tons. This means that you can save on the transportation of material and on the foundation - it may not be so solid. A shallow ribbon foundation is quite suitable.
Easy installation also means that the CIP -Panels are easy to cut into the right pieces and give the desired shape.
A house built of CIP panels has a minimum number of connections, so the risk of errors during the construction process is minimal.
Fire retardants are added to reduce the fire hazard of expanded polystyrene in its manufacture. The resulting material is called self-extinguishing polystyrene foam and is indicated for a number of Russian manufacturers with an additional letter "C" at the end. In the GOST-CIP panels it is allowed to use only PSB-S (self-extinguishing).
On top of the OSB (oriented strand board), you can put a wind-protective film and siding, which can be mounted directly on the OSB without additional crates. Or, you can simply paint the OSB with a good paint by nailing the slats in front of the joints of the panels for their additional protection.

Now let's move on to the myths that, despite the youth of technology, have already formed around the houses from CIP panels.
are also attributed to houses and buildings. sensitive, especially for those who are in the process of choosing technology for their future home.
It is not known exactly where this assertion came from, but there is no doubt that the mouse in its right mind would not eat expanded polystyrene foam.
Another issue is that mice can make moves in a heater and make nests for themselves - theoretically it is indeed possible. But it must be borne in mind that if the house is built correctly, in order to get to the insulation, you must first gnaw through 5-10 cm of the board or beam, and if there is a crate on them (as it should be according to technology, if protection against mice is mounted), rather the whole mouse will go to arrange their own housing elsewhere.
As a result, here it is necessary to clearly understand that mice do not have to run in flocks to the CIP house, if one appears in the district. These animals have been living in wooden and stone houses for hundreds of years - they appear where they can find, what to eat, and nothing more.
Some home owners jokingly say that "not managed to enjoy the construction process. "
On our website you can familiarize yourself with the most popular projects houses from the CIP panel from construction companies represented at the exhibition of houses Low-Rise Country.
Another of the most widespread myths that is attributed to the main disadvantages of houses from CIP panels is its combustibility and easy flammability.
Immediately, we note that CIP panels, made in accordance with certified technology, do not pose a threat to buildings in terms of fire hazard.
Harmful impurities usually secrete panels that are made with impairments. To avoid this, you should buy quality panels, be sure to be certified, as well as with the prefix green or eco in the name.
Firefighters say that houses built from CIP panels burn about the same as other houses, including brick ones. The main reason is that first of all, the floor, furniture and textiles will light up during a fire. And if in the house on the floor is laid laminate, linoleum, and the furniture is made of chipboard, then when burning, they emit harmful substances. And in this case, unfortunately, the material from which the house is made is of less importance. Before the burning of the walls may not reach.
CIP-panels burn badly - independent burning no more than 4 seconds. They self-extinguish.
What are hip panel manufacturers hiding? Ecology in the sip-house. What is she really? Do manufacturers of SIP houses cheat us? See all the answers in this video:
"If I do not burn CIP, it does not burn." This is confirmed by the owners who wanted to get rid of the trash after building the house, trying to burn them.
For additional protection against fire inside the house, walls can be sheathed with fire-resistant gypsum plasterboard, and outside with fiber-cement panels that do not burn because they do not contain combustible elements.
It should be noted that there are different categories of OSB plates and the content of phenol in them is strictly regulated.So, it should be remembered that the OSP-3 is better to use when exterior work, and for the interior decoration is recommended plate brand OSP-2.
Expanded polystyrene is closed by OSP panels and does not openly come into contact with the interior of the house.
It is known that up to 40% of heat loss in the house is due to the fact that the walls breathe. Thus, the fact that the walls do not allow air and moisture is a plus (the house does not let the cold from the street and does not release heat from the house), and minus the house (dampness and fungus can form).
And this problem is easily solved. In the house of CIP panels in order to breathe well and so that the house does not lose heat, you should install forced-air ventilation with a heat exchanger.
The advantage of ventilation with a recuperator is such a system not only updates air, but also returns to the house up to 90% of the heat that could escape through the exhaust pipe.
It is often said that “my house is my fortress”, and a house from SIP panels cannot satisfy this condition.
However, these are only speculative conclusions. Tests of SIP panels showed that they can withstand a longitudinal load (horizontal) up to 10 tons per meter and about 2 tons with a transverse load (vertical). And this suggests that it is possible to build a two-story house from CIP panels, and the house easily withstands snow loads on the roof and floors, and no strong winds are afraid of such a house.
So say those who observe after a certain time in their houses built of CIP panels, skewed houses. However, experts say that this is only possible if half-timber wood was used for the vertical uprights of the house. You should use well-dried wood, otherwise the recovery of deficiencies will be very time consuming and costly for the budget.
Wiring inside CIP-panels cannot be laid, as this will damage the integrity of the CIP-panel, which means that this is a violation of the house building technology. Violating the integrity of the SIP panel, the owner loses the warranty on the house. You should know that, in particular, the wiring should be carried out only outside in special boxes or sewn into the walls under the drywall.
Sound insulation in the house of CIP panels is the same as in the traditional carcasses, due to approximately the same density of expanded polystyrene and mineral wool. And the people living in the frame house are very pleased with the sound insulation in their homes.
This is not true. Even kitchen cabinets are easily hung on the walls of CIP panels. Two 3.5 * 40 mm screws, twisted into a 12-mm OSP panel, are able to withstand a force of 230 kg.
What is included in the turnkey price? How much is a separate warm contour? How much does engineering cost in a vulture house? Answers to all questions look in this video:
Each construction technology and any building material has its own advantages and disadvantages . As a result, the final decision should be made on the basis of a specific situation - allocated for the construction of the budget, personal preferences, the climate in the region and other factors. One thing is certain: if a certain technology has been chosen for building a house, then it must be observed in order to guarantee quality results.
