This technology is an industrial production of houses from sandwich panels. All parts of the house are manufactured in the factory with high accuracy and are delivered to the construction site completely ready for installation at home. This allows you to provide ultra-fast installation of the house and start finishing work for 3-4 days after the start of installation!
This panel, which has a three-layer construction and has unique mechanical heat-saving characteristics. The outer layers of the panel are made of OSB (oriented chipboards), the inner layer is PSB-C (self-extinguishing structural polystyrene foam). The panel elements are joined together by gluing using polyurethane adhesive.
From the point of view of mechanics, the sandwich panel (sandwich panel) is a spatial carrier of the verma, which allows to exclude almost all elements of the frame from the construction of the house. The use as an inner layer of PSB-C, which is an excellent thermal insulation material, provides unique heat-saving properties of sandwich panels.
The use in the manufacture of sandwich panels only environmentally friendly raw materials and technological processes makes it possible to obtain a modern environmentally friendly building material.
The structural thermal insulation panel consists of two oriented OSB (Oriented Strand Board) boards between which a layer of solid expanded polystyrene is glued under pressure as a heater. The thickness of the panels in the finished form is from 120 mm to 224 mm. The standard panel size is 1.22 meters by 2.44 meters. The maximum length is up to 7 meters. Such a panel has exceptional energy-saving properties and has high strength.
The technology of low-rise construction of SiPs is used in Ukraine relatively recently, in the world such construction is especially popular. This is due to the unique heat-insulating and moisture-resistant qualities of the materials: in such a house, in the coldest weather, it's warm, and in the summer heat it's cool. Frame houses made using SiPs technology meet all the requirements of modern life - environmentally friendly, durable, reliable and affordable.
Today it can be argued that polystyrene foam has a durability of more than 40 years, and even, perhaps, several times more. After all, polystyrene is a relatively young material.
For the first time this foamed polymer was obtained in 1952 by BASF. About its durability speak the results of the experiment conducted by this firm ... Styrofoam, laid under the roll roof as a heater roof of the building in 1955, was removed in 1986. After examining the extracted sample, a special qualified commission found that after 31 years, or functional changes in expanded polystyrene, it, as before, meets the requirements of German standards. The confirmed life of the house from SIP panels is more than 40 years, the estimated service life of the house is not less than 80 years.
The building, built using SiPs technology, is of a constructive type, refers to frameless (with bearing walls), i.e., most structural elements combine carrier and enclosing functions.
The construction of walls made using SiPs technology has a high strength allowing to build buildings even in seismic and tornado areas. This is due to the highest rigidity of the structure in combination with low weight. The sandwich panel, due to monolithic gluing, withstands a vertical load of 14 tons per 1 panel with a width of 1.25 m and a transverse load of 4.5 tons per 1 sq. M. (for construction of cottages it is enough 350 kg per 1 sq. m.
In America and Canada, of similar designs, houses are built on 5 floors. Construction requirements in Ukraine limit the number of storeys of buildings constructed from wooden structures by two floors (safety margin is more than sufficient).
The basis of the technology of SiPs is the use of two basic materials: Foamed polystyrene foam and flat-pressed plates with oriented wood chips (OSB).
Foamed polystyrene foam has a cellular structure consisting of 98% of air and 2% of polystyrene. This material is hypoallergenic and absolutely harmless to humans. A significant amount of world production of expanded polystyrene goes to the production of food packaging and dishes.
The OSB (Oriented Strand Board) is an oriented chipboard, where a rectangular flat chip with a thickness of 0.6 mm and a length of up to 180 mm is stacked in three differently oriented layers and pressed under high pressure and temperature conditions using wood resin and modern polyisocyanate adhesive MDI), which does not contain phenol-formaldehyde. MDI - reacts with the hydrogens contained in the wood, forming polyurethane, which gives the plate additional reliability and hardness. An important argument when choosing an OSB plate is a small amount of glue in the slab (less than 3%) finally polymerizing a month after pressing. Therefore, the plate is classified according to the hygienic class E1.
These materials are not a nutrient medium for mold fungi and bacteria, are not susceptible to putrefaction and insect damage, do not contain volatile elements. The production houses of our company are absolutely safe for humans and the environment, unlike materials based on stone, slag (mineral wool) and cement (foam concrete, aerated concrete) raw materials.
Following the countries of Europe, Ukraine adopted new standards of heat resistance of enclosing and load-bearing structures aimed at reducing operating costs and energy saving. As calculations have shown, homogeneous structures do not economically meet the norms of construction heat engineering. That is why today the technologies of multi-layer structures are rapidly developing, where one part fulfills the supporting function, the second - the thermal protection of the building.
Canadian technology of low-rise construction in terms of its heat engineering and price indicators is the best offer from all those on the market.
High thermal properties of SIP-panels provides the use of a highly effective insulation - expanded polystyrene. Styrofoam is durable, does not crack, is not a nutrient medium for microorganisms, rodents and other living creatures, does not rot, does not mold and does not decompose. Air permeability allows the building to breathe. Styrofoam is resistant to chemical and biological agents. Expanded polystyrene, in its thermal insulation properties, surpasses many traditional materials, including mineral wool. It is second only to polyurethane foam, but much cheaper than it.
In accordance with current regulations, the maximum level of heat loss for a house of 100 m2 is 10 kW / h. An important factor affecting the thermal insulation properties of materials is water absorption. Humidity contributes to the increase of thermal conductivity: the raw material has a higher coefficient of thermal conductivity and has worse thermal protection characteristics than dry ones. This is due to the fact that when the material is moistened, its pores are filled with water having a high thermal conductivity coefficient (approximately 20 times greater than air).
That's why houses built using SIP technology using a polystyrene foam heater are the warmest and require the least operating costs. In a period of constant increase in heating prices, such a building fully pays for itself within 10 years only on saving heating costs. In this case, the owner of the building does not need to purchase a powerful and, accordingly, expensive heating installation. Therefore, thanks to the properties of the materials from which the SIP panel is made, it has unique strength and exceptional energy-saving properties. Houses manufactured using this technology can be operated in the temperature range from -50 ° C to + 50 ° C and provide comfortable living even in the harshest climatic conditions.
Characteristics of expanded polystyrene:
When burning and recycling, it does not release toxic gases harmful to human health. Unlike mineral wool, which includes phenol, urethane, formaldehyde, glass, stone, slag compounds, condensation products of resins - and according to the results of the German Federal Environmental Service, these substances are classified as hazardous to health.
When finishing walls with gypsum boards, the limit of fire resistance of structures is 1 hour. Thus, the houses mounted by the company, although not fire-resistant, as well as all the wooden houses, but surpass fireproof houses made of traditional materials such as wood (the group of flammability of wood - G3).
Thanks to the use of prefabricated sandwich panels, a high speed of house mounting has been achieved. Assembled with the highest precision in the factory, the house is mounted on site without the use of heavy equipment, and at any time of the year. The panel modules are easily transported and installed by two or three people (the weight of 1 m2 panel thickness 164-224 mm is 18-20 kg).
The house is assembled by a team of 5-6 people for 3-4 weeks, the total construction period is 5-6 months. The house does not shrink, so you can proceed to exterior and interior finishing immediately after installing the basic structures. This advantageously distinguishes this technology from the construction of a beam, foam concrete and brick, where it is necessary to give time for shrinkage from 6 to 10 months. With a ready-made foundation, the house is assembled from sandwich panels, regardless of the season.
Using the technology of low-rise construction of SiPs, you will be able to enter a new comfortable house in 4-5 months. Low cost of construction - a house at the price of a car !!!
The cost of construction on SIP-technology is significantly lower than all major construction technologies.
You save money on heating the house in winter and conditioning in the summer. The house, built of SIP panels, is 8 times warmer than brick! The cost of operating such a house (heating and air conditioning) is 5 times less than usual! You save money on construction: The house made of SIP panels is lighter than stone, so there is no need for an expensive foundation - your foundation is 4 times cheaper than normal!
You do not need lifting equipment - all panels are easily lifted and installed by two workers!
You save time and money on assembling the house - due to the high speed of installation, a team of four workers builds a house on a ready foundation in just three weeks!
You save time and money on the interior and exterior decoration of the house. The walls, corners, floors and ceilings, built of SIP-panels, perfectly even! As a result, you need much less material for finishing surfaces (plaster, etc.) and money to pay workers!
The construction of the walls and the properties of the OSB-Lit allow the realization of any traditional and modern finishing technologies!
The houses are erected at any time of the year!
A solid foundation is the foundation of a solid home. The depth of the foundation and the type of foundation depend on the bearing capacity of the soils, the terrain, the groundwater table and the expected load on it. It is generally believed that the cost of erecting a foundation is approximately 20% of the value of a house. However, when designing and building light buildings from SIP panels, it is most advisable to use low-buried foundations, which can significantly reduce the consumption of materials and reduce labor costs.
SIP panels have a low mass, which makes it possible for two workers to carry and mount them without much effort. Delivery of panels to the construction site is possible with a vehicle with a small load capacity.
Pre-installation layout of panels is carried out along the perimeter of the construction site, according to the working drawings of the house being assembled. Installation of the house begins with fastening to the ready foundation of the bar, treated with an antiseptic, which is a binding strap for mounting panels. Fastening of the beam to the foundation is carried out by anchor bolts through a waterproofing material using a movable template. SIP-panels are tightly connected with each other with the help of locks of the type of spike-groove, made with high accuracy in the factory. In order to avoid the formation of cold bridges at the junction points, all minor voids are filled with a mounting polyurethane foam sealant.
The plinth panels overlap the edges of the harness, forming an even, solid board. The grooves between the panels are frosted. Between the wall panels and the floor panels to compensate for the thermal expansion, a gap of 3 mm is left. For waterproofing, the underside of the floor panels is covered in the factory with a layer of bitumen mastic. The wall panels are installed on the guide board, nailed to the floor panels using a template, and attached to it with screws.
A mobile template is used to precisely set the binding plates. With its help, the correct positioning of the boards is controlled and correction of their installation along the entire perimeter of the flooring is carried out. Installation of SIP wall panels starts from the corner of the prefabricated house. The first wall panel is set according to the level with a maximum permissible deviation of no more than 1 to 1.5 mm.
The second corner panel, the end of which is covered with a board or OSB, is connected at right angles to the first panel with the help of seaweed, sealing the joint with a polyurethane foam sealant. For the assembly of corner panels, no more than two fitters are required. The lower groove of the SIP wall panel is put on the strapping bar and fixed to it with self-tapping screws. The exact linear dimensions of the wall SIP panel allow you to assemble the house with a tolerance of no more than 1-2 mm. Panels with window and door openings are installed and fastened, as well as solid walled.
The vertical position of the panels is checked using the level. Internal partitions in the house can be made with wall SIP-panels with a thickness of 120 mm or standard wooden frame structures with the filling of voids with soundproofing material. The correctness of vertical mounting is checked by the measuring level. Overlap plates, the ends of which are sewn up with OSB, are laid on the wall panels of the ground floor bound with beams and fixed to it with screws. After that, on the sides, on which the rafter structures will rest, the Mauerlat cantilever is fixed.
Non-standard components, for example pediments, are manufactured in the factory, with pre-made doors and windows The roof construction is assembled using traditional methods. When using an attic space under the attic, the roof surface is also carried out by SIP panels, with correction of the roof structure according to design loads. Upon completion of the installation of roofing panels, a waterproofing material is laid on the external surface of the roof. Thanks to the smooth surface of the OSB plates, the laying of any of the roofing materials is done quickly and efficiently. The main material used is metal roofing. In order to reduce production costs, it is possible to use Ondulin and galvanized corrugated sheet.
Interior partitions of the first and second floors are frame structures assembled from 100 x 100 mm beams and 30 x 80 mm boards with steel zinced corners and self-tapping screws. Joints of panels become leakproof as a result of sealing gaps with mounting foam. Roof and wall panels are connected by self-tapping screws.
Upon completion of the installation work at home, the installation of plastic windows with double-glazed windows. Finishing works are done after the installation of door and window units in the openings. The next stages of the work are carried out in parallel, independently of each other. Seams between slabs of floors and walls from the inside shpaklyuyutsya and sanded under the coloring and pasting wallpaper on a non-woven basis. The surface of the exterior walls is primed, jointing seams are glued with reinforcing mesh, and the facade is painted with acrylic textured paint (acrylic coat) or, if the customer wishes, is covered with vinyl siding. After painting the facade work is done on the lining of the base of the house with decorative tiles, mosaics made of wild stone or plaster for "coat."
To protect against possible damage, the corners of the building at the entrance are glued with a double paint tape, primed and shpaklyuyutsya. Decorating the socle with decorative stone is made by insulated foam and reinforced masonry net surface. After performing these works, the windows are installed with ebbs and a drainage system is installed. In conclusion, the wooden fences of balconies are treated with stain and covered with varnish.
A common way of installing wires and cables is to lay them in the cavity of the frame partitions. For this purpose, the walls are provided with mounting, branching and junction boxes and special channels for sleeves with wires are left. There is also an external laying of communications of all kinds.
The electrical board is mounted on the wall in the hallway by an open method. By the same principle as an electrician, plumbing is installed in the house. Communications of the first floor are laid depending on the device of the floor. In the absence of a basement floor, they are placed in the ground. When the basement is insulated, the sewer and water pipes can be fixed to the floor beams. The route of pipes inside the house is in the interior partitions. It is possible to arrange warm floors, both electric and water. The water supply, sewage and ventilation is installed in specially designated mines.
The assembled house simultaneously carries out roofing, engineering and installation and finishing works. Preparing for painting the facade.
The exterior decoration of the house is carried out with wooden scaffolding, supports and stairs. Works are made on all walls simultaneously, in extremely short terms and only in dry weather.
The exterior painting is carried out in two layers. The paint is produced in an amount sufficient to cover the entire house.
The design of the walls allows the implementation of any traditional and modern finishing technologies. However, it is preferable to use dry processes, without screeds, masonry work, plaster application. This reduces the time for putting the house into operation. Interior partitions are faced with plasterboard, cement-chip or OSB-plate. Over the panel flooring, any type of finish coating is applied. Walls and ceilings can not only be painted, but also covered with wallpaper, covered with a board.
After installation of engineering communications, a two-layer screed can be poured over the ceilings. The first layer (20-40mm) is concrete with a density of 30-40. The second layer - reinforced with a road net sand and cement screed mark 150, with the addition of plasticizer, a thickness of 40-50 mm. In the premises of the bathrooms before the beginning of the pouring of the screed and the laying of communications, waterproofing is done, then the sewage and water pipes are installed, then the screed is poured, but with the addition of a moisture-proof composition into the solution.
Premises of bathrooms are faced with ceramic tiles. In this case, the walls are pre-primed, reinforced with a glass mesh and shpaklyuyutsya special composition.
Preparation for painting involves gluing joints with paint tape, puttying and sanding surfaces. Such work requires an order of magnitude less time than the finishing of a brick building. The choice of materials and stylistics of exterior decoration are determined by the customer (siding, tile, board-blockhouse, stone, plaster). Most often, preference is given to water-resistant fillers with subsequent coating with water-resistant paints on acrylic or alkyd base. Wealthy customers can clothe the facade of a panel house with a brick. As a result of the democratic level, the building becomes an elite building. The wall of the face brick is laid out on a joint with the panels of the foundation. Between the masonry and the panels, a ventilated space (10 cm) is left. For greater strength, the panels and brickwork are tied with five-millimeter wire connections. Outside, the foundation ribbon can be plastered, tiled or tiled.
