Self-construction at home takes a lot of time and labor. Wanting to save money, time and effort, people compare different options construction using modern materials And construction technologies. In our article we will tell you how to make a house from OSB with your own hands in the most short terms, with minimal financial costs.
Economical construction
The cost of constructing a building from scratch can fluctuate over a wide range and depends on the prices of the building and construction materials used. finishing materials. Today it is considered the most accessible and reliable frame house from OSB boards.
To build such a house, there is no need to hire a team of professionals. Construction is reminiscent of assembling a large construction set, the elements of which are ordered at the factory according to the developed project.
The advantages of building a house from OSB are obvious:
- A clear definition of the cost of the future structure.
- There are virtually no unexpected expenses.
- The developer pays only for the materials he needs.
- Each purchased panel has its own place in the building and there are no surpluses or unaccounted expenses, which allows you to save up to 25% of the cost.
- The developer will save a decent amount of money on the construction of the foundation structure, since for frame house no need for a massive base.
- Ideally smooth walls of a building do not require expensive finishing work.
- Insulation materials are laid inside the walls, which makes the house especially warm and reduces the cost of the building heating system.
- The prices for the material used are significantly lower than the cost of bricks.
OSB boards are used both for installing formwork for the foundation and for the construction of all walls, partitions, floors and roofs.
For walls, slabs with a thickness of 9 mm are used, and for floor installation - 12 mm.
Instructions for building a house from OSB boards
Stage No. 1. Foundation. For a frame house, the best option is strip foundation. The depth of laying the foundation for a house depends on the climate of your region. If the soil freezes no more than 80 cm, the foundation is made shallow. For its construction there is no need to attract additional labor.
Sequence of work:
- Level the construction site, make markings and planning.
- Dig trenches for the foundation.
- Level the bottom of the trench and compact the soil.
- Lay water-repellent membranes or roofing felt as a waterproofing layer.
- Cover the bottom of the pit with a five-centimeter layer of sand and a twenty-centimeter layer of crushed stone. Tamp down well.
- Install formwork from OSB boards.
- Install the reinforcement cage.
- Pour concrete into the base of the house.
When located construction site on stable, dense soil, you can install a columnar foundation, which is advantageous in terms of economy and ease of work. Many developers install a column-and-strip base for a frame house. The supports are tied with concrete tape - a grillage.
Stage No. 2. The walls of the house are made of OSB. Place a waterproofing layer on the foundation.
Sequence of work:
- Place a beam measuring 15 * 15 cm on the concrete strip and strengthen it with metal brackets. This will be the bottom harness.
- Mark the location of window and door openings.
- Assemble the frame of the house from vertical posts. For this, boards 3 cm thick and 15 cm or 20 cm wide are provided. A narrower board is suitable for southern regions, and wide - for the northern ones. At the junction of two walls, in corners and doorways you need to install double boards.
A thicknesser will help make the board smooth with the same width and thickness. Before starting to assemble the building frame, all structural elements must be treated with an antiseptic.
The boards must be installed so that the ends are outside and inside the building. For attaching the top and bottom trim use with boards metal corners and self-tapping screws.
Upon completion of the assembly of the frame of the first floor, proceed with installation ceiling and construction attic floor or installation of a rafter system. The faster the roof is erected, the less likely it is that the installed frame will be damaged in the event of bad weather.
Stage No. 3. Rafter system. Build the farm according to the design of the house from OSB boards. The sides of the truss are installed simultaneously on both sides. Attach the structure to the ridge with self-tapping screws, and to the floor beams with staples.
If the rafters are shorter than the length of the roof slope, it is necessary to double the slopes and connect them with an overlay beam equal in width to the rafter board. After installation roof truss start working on the gables.
Sheath OSB roof slabs, laying them so that the long side is along the slopes. Once the roof sheathing is complete, begin installing the slabs on the gables.
Stage No. 4.
It's time to sheathe the walls.
The installation of the slabs must be done so that there is a 2 mm gap between them.
Wall covering can be started from any angle from the foundation and upwards. You can sheathe one wall first, and then start working on another, or sheathe it at the same time external walls. Window and door openings remain open.
Insulate a house from OSB mineral wool or polystyrene foam. If cotton wool is used, it is necessary to arrange a ventilated façade on the outside. Make a sheathing for the entire house using wooden blocks. It is on the sheathing that the decorative material will be installed.
Bookmark thermal insulation materials must be carried out very carefully so that there are no cold bridges.
Mineral wool can be laid in two layers to cover joints. When using polystyrene foam to insulate the walls of a house, the cracks are filled polyurethane foam. When the thermal insulation layer has been laid on the external walls, you can begin covering interior walls.
Stage No. 5. Ceiling and floor covering. Many developers first sheathe the floor and only then start working on the walls. To insulate the floor, foam plastic is used, laying it between beams hemmed with transverse bars or sheets of moisture-resistant plywood.
The same cladding technology is used for the ceiling.
Stage No. 6. Internal and exterior decoration. Any materials can be used to decorate interior walls. The only thing that is not recommended is plastering. OSB boards are in excellent contact with primers, varnishes, and paints.
The floor is covered with porcelain stoneware, parquet, laminate, polyvinyl chloride board, linoleum. Particle boards have an excellent, smooth surface, which allows for high-quality masonry ceramic tiles. You can even install a heated floor, which will not affect the thermal conductivity and strength of the slabs.
The facade has an excellent surface. It is enough to cover it with a primer and paint it in any color. Use bars of a different color and make a half-timbered finish. This is the most cheap option finishing. More expensive materials can be used.
Windows and doors are installed both wooden and metal-plastic. There are no restrictions. It all depends on your personal preferences and tastes. By choosing a frame structure project with OSB boards for construction, you will very soon move into your home.

Apartments for dolls are often expensive and are made of plastic - a fragile material that breaks easily. The article describes how to make a toy house with your own hands.
To make a child's dream of a house for his favorite doll come true, it is not at all necessary to go to the store. You can make a cottage from your own design.
Arguments in favor of self-production
Why you should build a homemade dollhouse from plywood:
- Individuality. The project will be unique.
- Working together with a child. Helps strengthen family relationships.
- Development of creative abilities, skills, motor skills, acquisition of new experiences by children.
- Possibility to create a house of any size.
Why plywood
A doll's house is made from different materials. Best option- plywood:
- The use of plywood for construction ensures the strength of the future home. At good fastening parts do not fall apart or break off.
- Plywood is easy to process with conventional tools.
- Wooden toys are pleasant to the touch.
- Beautiful appearance wood allows you to do without additional decoration and surface design.
- Low material cost.
What to pay attention to
Formaldehyde is used in the production of plywood. They are part of the impregnating adhesive for joining fibers. To avoid poisoning or hazardous material getting into the children's room, you need to pay attention to the markings of the sheets:
- E0 - less than 6 mg of formaldehyde per 100 g of product;
- E1 - 7–9 mg per 100 g;
- E2 – 10–20 mg per 100 g.
Furniture and its components must be made from the safest class of plywood - E0.
How to do
Making a house for dolls from plywood is a multi-step process. A certain sequence of actions must be followed. To make the work easier, you can use step-by-step instructions.
Stage 1. Sketch preparation
The diagram should show the layout, floor dimensions in length, width, height.
You can find a sketch on the Internet and adjust it. The photo shows several basic diagrams of a toy home.
The most important thing is to maintain the proportions of the sizes to scale. This is necessary in case you want to change the dimensions of the product during operation.
The design can be thought out in advance in order to purchase and prepare necessary materials for decoration.
Stage 2. Preparing accessories and tools
For assembly you will need:
- Plywood. To determine its quantity, use a drawing: calculate the number of parts, their sizes, get total area surfaces. Based on the result, purchase the required number of sheets. For a tabletop house you will need 2–3 blanks; for a large mansion it may take up to 7–10 sheets of plywood.
- Corrugated cardboard for the roof.
- Tool for cutting wood. It is recommended to use an electric jigsaw. It will help you quickly and accurately cut out parts of the desired shapes and dimensions.
- Wood glue for fixing assembly elements.
- Mounting tape as an aid for fastening parts.
- Fine sandpaper.
- Tape measure, ruler, pencil for marking.
For registration you will need:
- PVA or silicate glue.
- Wallpaper, color films.
- Self-adhesive film to imitate flooring.
- Colored cardboard or paper for decorating individual elements of the premises (optional).
Stage 3. Image transfer
To assemble wooden parts into a single whole, they must be cut from a blank sheet. To do this, scale sketches are transferred to paper, finished parts are cut out of it, and later used as a template.
If the windows are not indicated on the diagrams, they are drawn when transferring the patterns. At the house flat look Without the front wall, cuts for windows are not needed.
Stage 4. Assembly
Step-by-step assembly instructions:
- The parts transferred to the plywood are cut out using an electric jigsaw. They try to do this carefully, without going beyond the contour lines: if there is a mistake, the structures may connect incorrectly.
- Sand the edges to make the parts safe and avoid injury.
Cutting and finishing of edges should be done by an adult.
- Assembly begins with combining the interior space. Floors and internal partitions are attached to the vertical end walls using glue and mounting tape according to the diagram. To strengthen the connection internal corners glued with thin slats. They will add rigidity to the structure. At this stage, the child may be involved in the work.
- Flights of stairs are made of wooden rulers. They are placed in the form of slides or cut one and glued together into a real staircase.
- Attach back wall.
- Assembling the roof. You can cut out whole slopes from cardboard and glue them together. Another option is to assemble the roof from individual pieces in the form of tiles.
The finished frame of the house is left for several days until the glue dries and the structure acquires sufficient strength.
After assembly, the design begins.
Stage 5. Design
The finished frame is decorated and furnished with doll accessories. Recommendations:
- The floor can be left as is or decorated. Plywood has a wood pattern, so covering it with a similar pattern is impractical.
- You can make hinged windows and doors. To do this, lay the canvases on pieces of cardboard or use small metal door hinges. The passages are covered with fabric curtains. Windows are sometimes replaced with cardboard shutters.
- The ceiling and walls can be covered with colored films, wallpaper, or painted.
- Furniture for toys is placed in the rooms.
Additional features
Not only the aesthetic, but also the practical side of the house is important: toys need to be stored somewhere, accessories need to be put away, something needs to be hidden. You can make additional built-in drawers in the upper or lower tier. This is appropriate if the house is large and takes up significant space in the living space.
Boxes are also made from plywood. The drawing provides space for storing things. The sides of the box are cut out of plywood and glued together. Screw the handle and insert it into the compartment.
You can make a hinged door like in the photo. To do this, the cut canvas is screwed onto metal loops.
Conclusion
A homemade plywood toy house will be a good gift for any child.
The construction process will take 2–3 days, taking into account the preparation of blanks, their cutting, and drying of glue. The child can decorate the premises independently.
Just like boys dream of a tree house, girls also dream of dollhouse for your favorite toys. Of course, you can buy it, but a good house costs very indecent money, and you can’t buy a bad one for a child. It's another thing to do it yourself, but be prepared for it to take a lot of time. Especially if you don't have much experience. On average, it will take at least a week to make a doll house with your own hands.
Choosing material
You can make a doll house with your own hands from any sheet building material. The thickness of the material for a house about a meter high (on two floors) is 9-15 mm, for one-story houses it can be thinner. Let's look at the most common materials used in the construction of a dollhouse:
- . Great choice, since it is durable, holds its shape well, can be glued, connected using nails and self-tapping screws. Cut plywood with a metal saw (with a fine tooth) or a jigsaw (manual or electric). The ends will need to be sanded well so that there is no possibility of driving in a splinter. Upon completion of the work, you can varnish or stain, paint, wallpaper, etc.
- Drywall. After the repair, there are scraps left that can be used. To fasten the sheets together you will need tin corners (you can use a perforated corner). You will have to attach it to special screws, but they will stick around back side, so it's not the best option. You can try to “plant” it with glue, but you will have to align the cut lines to reduce glue consumption.
A plasterboard dollhouse is one of the possible options
- . The properties of the material are similar to plywood, the only difference being that it is moisture resistant and made from wood chips. Working with it is approximately the same as with plywood.
OSB is also a good material
- Cardboard. The most inexpensive and most delicate material that does not hold loads very well. The situation is better with cardboard for scrapbooking (you can buy it in craft stores). It is denser and more durable; it can be made into one-story houses or used for roofing. Connect using glue or staples from a stapler. To make the doll house more reliable, it is better to assemble a frame from planks and then cover it with cardboard.
- Regular or laminated chipboard (). The advantage of this material is that it can already be finishing. If you wish, you can order sawing of the entire “box” of the house with gluing of the edges from some furniture company. Then all that remains is to assemble. Moreover, it will be possible to use screws or furniture fittings. There are three disadvantages - the material is too thick, which increases weight, formaldehyde emissions and fragility under lateral loads. If you can put up with the thickness and weight, then the release of formaldehyde should not be ignored. You need to look for ones with emission class E0-E1. Unfortunately, there is nothing you can do about fragility. Unless you use corners to connect parts, and this is not very beautiful.
- Furniture panels. They are made from wooden planks glued together using wood glue. Ideal option for making a dollhouse: environmentally friendly, durable, easy to process. But furniture panels You can’t call them cheap, although they are not as expensive as an array. In any case, it can be used to make a box - the bottom, side walls and ceiling. The roof and back wall can be made from other materials (for example, fiberboard, plastic, etc.).
Furniture board is an environmentally friendly and beautiful material
There are also such options as laminate, wooden lining, thin planed board. But they don't work with them that often. Anyway minimum thickness materials - 6-7 mm. Then the dollhouse will be reliable and will even support your child.
Features of working with plywood
Most often, plywood is used to make a dollhouse. As you probably know, she may be different brands. It is better to make a dollhouse with your own hands from sanded furniture plywood. You can use them from coniferous trees, but preferably from birch. It’s better not to take a construction one, even though it costs twice as much.
In general, working with plywood is not difficult. If you have a jigsaw and a jigsaw, cutting and preparing the parts will take a couple of hours. The only difficulty that may arise when making a two-story plywood doll house is the installation of the second floor. T-shaped fastening of plywood is not the easiest task.
The glue is not very reliable, and trying to install screw-type fasteners into the end with a thickness of 6 mm is difficult - the material can split, even with pre-drilled holes (the thinnest self-tapping screw is 1.8 mm). There are several options:
- do it on nails (not very reliable, unless you coat it with additional glue);
- install corners at the bottom (not very nice);
- install a bead around the perimeter that will both support the floor and “work” ceiling plinth(the best option).
After cutting out the parts, all joints must be sanded well. First, use medium-grain wood sandpaper and gradually move on to fine sandpaper. Once the edge is smooth, you can begin assembly.
Dollhouse project
The first thing to start building a dollhouse is creating a project. You need to decide on the height and number of floors, the width of the room, the type of roof, and whether or not there will be a basement floor. Choose the number of floors as desired. This is arbitrary, but all other parameters must be calculated.
The size of the dollhouse depends on the size of the doll inhabitants. To make playing comfortable, the height of the ceilings in the rooms must be at least twice the height of the doll. For example, with a doll height of 22 cm, ceilings of 40-45 cm will provide enough space for them to move freely, but if the ceilings are even higher, it will be even more convenient to play. But you also need to take into account the child’s growth. The height of the topmost ceiling should be slightly below eye level. In this case, it will be convenient to play, and the dollhouse will be “growth-able” - its height will be enough for a couple of years.
The depth of doll rooms also depends on the height of the dolls, but also on the availability free space. On average, the depth is 30-45 cm. This is enough to accommodate the entire furnishings. But it could be deeper.
The width of the dollhouse depends on the number of rooms in it. Here you decide depending on the available free space. In shape, the frame of a doll's house usually looks like a rectangle, but whether it is extended in length or height - this is determined by each person. If the structure turns out to be rather large, you can attach furniture wheels to the bottom. This is very convenient - the toy turns out to be mobile.
You can draw the project itself in any design program, but if you don’t own them, it’s easier to do it on paper. Why do you need a dollhouse project? To calculate the amount of materials required for its manufacture, and without the dimensions and number of walls, you will definitely be mistaken.
Finishing features
Decorating a dollhouse with your own hands raises no less questions than building it. In principle, you can use the same finishing methods as in apartments or houses. For example, in doll rooms, walls can be decorated in the following ways:
If you chose the option to “hang wallpaper”, it is easier to do this before the assembly stage. Even if there are several floors, the blanks are drawn out and wallpaper is glued. This is much easier than trying to cover the corners later.
The exterior decoration is not much different. Painting is most often used. This best option in terms of practicality and labor costs. If you want you can do something similar to decorative plaster. It can be imitated using gray toilet paper. You just need to choose thicker. It is torn into pieces, glued with PVA diluted with water (1 to 1), laid out on the walls, forming the desired relief. After drying, you can paint using acrylic paints. This and it can be used with colored or regular napkins.
Window and door decoration
Cutting windows in plywood, OSB, or any other material is not such a problem. First, using a drill and a drill bit, make a hole into which you can pass the saw blade. Next is a matter of technology. The cut hole is sanded until it is smooth, and then it is necessary to make the holes look like windows. For this you need frames and curtains. If desired, you can also make glass from transparent plastic bottles.
Frames with bindings can be made from cardboard white. Paste them after completion " finishing works" Children love to open/close doors, so it is better to make them from thin plywood. Fasteners can be found - there are piano hinges or small furniture hinges. You can make deadbolts from wire and thin tubes.
Let there be light!
A doll house with lighting is aerobatics. Moreover, there is no need to fence the system with wires, converters, light bulbs and other electrical “stuffing”. There is a very simple effective solution. Any more or less large lighting equipment store has small led lamps, battery operated. Moreover, they are mounted with Velcro. Each lamp is equipped with its own switch and operates on a voltage of several volts. In general, a very good solution.
These are non-volatile LED lamps
If you still want to make real light in a dollhouse, you need a 220/12 V converter or a battery with the appropriate voltage. You will also need light bulbs or led strip under the appropriate rating, a bunch of wires. In general, this path is much more difficult and requires much more time, but it is also a possible option.
How to make a roof
If the roof is planned to be ordinary - gable, the layout of the attic space or attic floor must be done so that there is a partition in the center that will support the roof at the junction of the two halves of the roof. This is the easiest way. There are also more complex ones.
If you need a roof with a complex shape, we cut out several rafters from plywood that will define the shape. We attach them to the walls and cover them with some flexible material. It can be cardboard, fiberboard. The ends of the rafters are coated with glue (preferably carpentry glue), after which the material is laid. If the bend is too steep, additional fasteners may be needed. Usually thin small nails, like shoe nails, are used.
Photo options of different doll houses
Building a dollhouse is a creative process. You can make it the way you dream of your home, or recreate a house from a fairy tale or fantasy. And there are no restrictions here. Everything you want and how you want.
A one-story house is not so bad either. But you can put it on the table and play while sitting
So different...
This is how to make shutters
Frame houses, which are increasingly gaining popularity, do not raise doubts about their practicality and operational efficiency. But what can be said about the construction process itself and the materials that are used to construct such buildings?
The main types of building materials for such structures are wooden beams, beams and OSB panels. It is the use of panels that provides a frame house with those characteristics that so attract developers.
What is OSB
For those who are planning to build a house from these materials, you should know not only the meaning of the abbreviation, but also the qualities that they possess, as well as the functional differences from other similar materials.
OSB panels are boards made from wood chips.
The meaning of the abbreviation translated from English language means “oriented strand board” - Oriented Strand Board.
The difference between these panels and the chipboards familiar to domestic developers is the installation method and the type of chips. If in chipboard the main component is pressed in a chaotic manner, then OSB panels in their structure contain chips laid in one direction, that is, oriented.
It is characteristic that the chips are laid in each layer in a different direction. The number of layers in each slab is three or four. Typically, the direction of laying chips is taken in the following order:
- First layer - fibers are placed parallel to the panel structure
- The second layer always contains the chip direction perpendicular to the direction of the first layer
- Third layer - again laying is done in the same way as the first layer
- The fourth layer is perpendicularly placed fibers
In some panel versions, another method of chip pressing is adopted, which includes parallel arrangement of chip fibers in the outer layers and their transverse placement in two inner layers.
To create a sandwich panel from OSB, shavings up to 15 cm long are used, which are pressed under high pressure. Their volume in the slab structure reaches 90 percent. The fibers of the chips are bonded with waterproof resins of synthetic origin.
As evidenced by numerous reviews of developers who used this material in the construction of their houses, it is this structure that provides many advantages for the operation of the house. One of them, which allows saving the consumption of energy resources during the heating period, is the high heat capacity of OSB boards.
Classification of OSB panels
For construction purposes it is recommended to use individual species panels, since the structure and properties different types differ and are not always suitable for the same purposes.
Reviews about the qualities of OSB panels lean towards the conscious choice of only certain categories of such panels.
In order not to make a mistake when ordering material, you need to study the characteristic parameters and classification of OSB boards. Moreover, this is not difficult to do - there are only four of them, and the differences mainly relate to the number of layers, the degree of strength and moisture resistance indicators:
- OSB-1 panels are boards with a very low degree of strength and a low level of moisture resistance. In construction, such panels can only be used in interior work. But more often their use is widespread in the production of furniture structures, as well as for packaging products
- OSB-2 boards have low strength, although slightly higher than panels of the first category. They can also be used in interior finishing works, sometimes in the construction of lightweight structural elements, ceilings and partitions. But due to low moisture resistance, it is not recommended to use basements, when finishing the basement floors and during internal works in bathrooms and kitchen
- OSB 3 is the most common model of OSB panels. It has proven itself excellent in exterior and interior work. Can be used in different parts buildings. Resistant in humid environments
- OSB-4 category panel is the most durable grade of OSB boards used in all types construction work. Due to its high strength, it can be successfully mounted on external parts building structure, when constructing roofs and attics. Excellent moisture resistance, making it suitable for use in lower parts buildings and rooms with high humidity
All these properties, inherent in each category of panels to varying degrees, are achieved by using an adhesive base of various compositions. Such boards owe their moisture resistance to the resinous compounds of the glue, and their strength to the arrangement of the fibers of the wood chips and the number of layers in the board.
There are differences in OSB boards based on the type of coating
The industry produces panels with a laminated surface that can be used as formwork, and more than once. For decorative purposes, slabs varnished on both or one side are also produced.
For device horizontal surfaces panels are produced with connecting elements based on the principle of laminate boards. On two or four sides of such panels there are end ridges and grooves for connecting adjacent slabs.
Reviews of OSB panels from buyers are inclined to believe that they have prospects in the production of finishing works and can act an excellent alternative in the installation of floors.
Properties of OSB panels
Reviews from panel buyers and developers note several significant advantages of this material:
- The technology of laying wood chips and the length of the chips make OSB panels more rigid, which allows them to become resistant to mechanical stress
- Thanks to the conveyor production method, the dimensions specified by the technological requirements are observed in the slabs. For the same reason, uniform thickness is achieved in all parts of the slab. This quality contributes to the ease of installation of OSB boards
- Reducing the labor intensity of the installation process, increasing the efficiency of construction. The panels are lightweight, can be easily transported and do not create additional difficulties during loading and unloading operations
- High thermal insulation rates are another significant advantage of this material. This property is achieved thanks to the high concentration of wood components, known for their thermal insulation properties.
- Availability during processing - OSB can be easily sanded, drilled, and cut. And when hammering nails, the edges of the slab do not crumble
| OSB properties | plate thickness 12mm |
| Length deviation, mm | +/-3 |
| Width deviation, mm | +/-0,3 |
| Thickness deviation, mm | +/-0,8 |
| Deviation from right angle, maximum, mm/m | 2 |
| Bending resistance, main axis, MPa | 20 |
| Bending resistance, lateral axis, MPa | 10 |
| Flexural modulus of elasticity, major axis, minimum, MPa | 3500 |
| Flexural modulus of elasticity, lateral axis, minimum, MPa | 1400 |
| Swelling in thickness over 24 hours, maximum, % | 15 |
| Density, kg/m 3 | 630(+/-10%) |
| Humidity, % | 5-12 |
| Thermal conductivity, W/(mK) | 0,10 |
| Formaldehyde content, mg/100g | <8мг/100г |
As for the specific use of slabs in the construction of houses using frame technology, in their reviews many builders and owners of ready-made residential buildings note the speed of construction and ease of installation work.
In terms of operation, there are also undeniable advantages:
- Houses made from OSB panels do not settle due to the lightness of the material
- In winter, there is a noticeable saving in energy resources, which eases the budget burden
- The ability to carry out additional planning of the premises without major intervention in the integrity of the structure
At the same time, in the reviews one can notice the absence of negative qualities characteristic of other materials, namely, susceptibility to rotting, the presence of formations in the form of knots and voids inside the panel, and the risk of fire is reduced.
Against the background of such a volume of advantages, individual disadvantages of OSB boards seem insignificant, but they cannot be ignored.
Among the main disadvantages of this material is the presence of phenol in adhesive resins, which can negatively affect health. However, in each category of plates listed above, the content of this element is regulated.
So when choosing slabs for a specific application, you need to focus on their main purpose. For example, OSB-3 is best used for exterior work, and OSB-2 is recommended for interior decoration.
Painting OSB panels
Application of paint materials on OSB panels does not require special conditions. Any wood paint can be used for this purpose.
For better adhesion to the surface of the slab and a longer shelf life, the surface of the panel can be primed.
For interior work on panels, you can use acrylic varnish. For the same purpose, stain or water-based paint is used. For all options, only positive reviews are noted.
Video about the production of OSB panels
Materials made from wood waste have all the positive qualities of natural materials and a lower cost. Modern technologies have made them stronger and more resistant to water and fire. Frame construction is becoming more and more popular. People like a house made of OSB boards, it is warm, light, and retains the smell of the forest for a long time. By ordering parts in accordance with the project, you can build a house with your own hands without lifting equipment and wet work.
How to build a house from OSB?
Improved qualities of natural wood in OSB panels
Wood surpasses all other natural materials in its qualities that create comfort in the home. Its disadvantage is swelling from water and fire hazard. Rodents and insects love to settle in warm walls, destroying them prematurely.
When producing solid wood products, a lot of waste remains:
- small pieces of wood;
- branches;
- wood chips;
- sawdust;
- shavings.
They are sorted, joined in various ways and pressed. The result is panels that take the best qualities of wood.
The production of OSB panels uses large chips, accounting for 80% of the mass of the slab. It is laid in layers, orienting the direction of the outer sides along the sheet. The internal chips are arranged transversely. Perpendicularly oriented fiber eliminates warping and shrinkage of the panels. Pressing and impregnation with synthetic resins makes the material more resistant to fire. It does not ignite and does not support combustion, but it chars and collapses. This does not release toxic substances.
OSB panels for house construction
In construction, there are 4 groups of OSB panels based on strength and moisture resistance. The table shows the main use of each type.
| OSB board class | Strength | Moisture resistance | Scope of application |
| OSB-1 | low | low | furniture manufacturing, interior partitions, interior elements |
| OSB-2 | average | low | only in dry rooms |
| OSB-3 | average | high | external and internal wall cladding, partitions and finishing in wet rooms, bathrooms |
| OSB-4 | high | high | all types of construction work, including plinths and basements, reusable formwork |
Walls made of OSB panels retain heat and absorb noise slightly worse than natural wood. The material has high environmental friendliness. The lack of wood in its combustion and absorption of moisture is eliminated by impregnation, additives and pressing.
When making house parts from panels with your own hands, you should take into account the location of the fibers and hardness. OSB cuts and drills worse than solid wood.
Frame houses are cheaper and quick to install
Frame house
The construction of residential buildings from OSB boards is carried out according to an approved project. Blocks are made at the factory and labeled. A light foundation is made on site and then the frame of the house is mounted on it and sheathed with the resulting parts. The insulation is installed during the production of blocks. This method of construction has a number of advantages over standard brick buildings.
- You can move into the house immediately after laying the roof and do the finishing, or simply varnish the inside walls.
- Construction is done using the dry method and takes less than a month, including the creation of the foundation.
- A frame house is 3–5 times lighter than a brick one. A light foundation at a shallow depth or a support-column foundation is made under it.
- To erect walls and roofs, you do not need to use lifting mechanisms.
- The smooth surface of the panels is finished without complex plaster. Putty is sufficient for painting and wallpapering.
- The material of OSB panels is used for insulation of brick and wooden houses. Additionally, polystyrene foam or other extruded plastic is placed inside. The heat in the house is retained better than with brick walls 1 meter thick.
- It's comfortable inside the house, the walls breathe.
- They do not shrink.
- There is no waste during installation; the blocks are made to size at the factory.
- The cost of a frame house made of OSB is significantly lower than a brick one.
Frame houses also have their disadvantages. If you want to have a basement in your house, you need to make a strip foundation to its entire depth or dig and lay out the walls separately, at a distance from the supporting structure. It is more difficult to hide the wiring with your own hands. Heavy equipment and cabinets cannot be hung on OSB walls.
Construction of frame houses
We build a house from OSB ourselves
If you want to build a house with your own hands from OSB, then you will need helpers. The optimal number for work is 4 people. You can get by with a minimum number of workers - 2 builders. Then one must have experience in assembling frame houses. The second is to be able to understand it, present it, hold it.
- A waterproofing layer is laid on the foundation. There is a lower harness on it.
- The racks and corners of the walls are attached, and a diagonal fastening is made to prevent the structure from “folding.”
- The top trim is installed.
- Floor and ceiling beams are laid.
- The frames of the openings are installed.
- The rafters are installed and sheathed.
- The floor and ceiling are covered.
- Sheathing is done with OSB panels.
- Sealing extensions are installed at the corners and joints of the panels.
When building with your own hands, the walls outside and inside of a residential building are sheathed separately. Insulation is laid between the layers of OSB, wires and life support systems are laid.
Advice! Self-tapping screws do not screw into OSB well and become warped. It is advisable to drill a hole for them. The drill diameter should be smaller than the screw thread.
For thermal expansion, a gap of 3 mm is left between the panels and racks around the perimeter of the floor. There is a gap of 2 mm between the plates themselves along the entire sheathing. The wall panels do not reach the floor covering by 10 - 12 mm. The finishing gap is closed with skirting boards.
The floor panels are laid on the beams across their location. There must be at least 3 crossbars under each OSB slab. Along the length, the ends of the sheets are connected on a beam. Both edges are secured with self-tapping screws. The pitch between the floor beams is 500 - 600 mm.
A house built from OSB panels can easily withstand outside temperatures from 40 degrees below zero to the same heat reading. The comfort of the buildings is not inferior to brick buildings with insulation and wooden houses. The walls breathe, removing moisture out. The air inside remains fresh. Fungus and mold do not appear.
OSB sandwich panels
DIY house made from OSB sandwich panels
OSB sheets are also used to create sandwich panels. The space between two slabs of pressed wood chips is filled with expanded polystyrene. Such a house is assembled by a specialized team. Sheathing, installation and fastening are used similarly to the construction of buildings made of sandwich panels.
The frame and lining of the openings are made from boards 3 cm thick. The starting profile is a strip equal in width to the groove at the end of the panel. It is attached along the entire perimeter to the foundation with metal brackets. The panels are fastened together with timber. They are fixed to the posts with long screws.
The interior of buildings is inferior to houses made of OSB boards in aesthetics. Therefore, such technologies are rarely used for residential buildings.
