Sheet building materials are used in frame housing construction, with dry leveling of planes. One of these materials is OSB board (OSB, OSB). She pressed, GKL. And all because with good technical characteristics, it has a low price.

What is OSB board and OSB

One of the sheet building materials is OSB (also called OSB). The name is an abbreviation of the full name of the material - "oriented strand board". That is, it is correct to call this material OSB. The second name - OSB - comes from the transliteration of the English version of the name - OSB ( oriented strand board). English letters were simply replaced with similar ones in Cyrillic.

OSB is a multilayer material (3 or more layers). Each layer consists of wood, ground into chips, mixed with resins. Wood chips are used long and thin (several millimeters thick, up to 7 cm long). Chips in layers are located in different sides: the outer layers have a longitudinal orientation, the inner layers have a transverse orientation. This results in high elasticity and dimensional stability. Various resins are used as a binder. They give the material water resistance, but contain formaldehyde. It is the content of this substance that stops many from using OSB. But, if the material is produced in accordance with GOST, the formaldehyde emission does not exceed the performance of wood. But you can only check it in laboratory conditions. So the ordinary buyer can only rely on the inspection authorities. Or choose another material.

Types of OSB

Depending on the consumer properties Oriented strand boards are produced in several types:

If you need moisture-resistant OSB, carefully consider the choice of manufacturer. Be prepared for the fact that OSB 3 is more expensive than non-moisture resistant brands. Even more money will have to be paid for OSB 4. Search cheap material we do not recommend. Too many complain that the purchased OSB 3 swelled by 3-8 mm from moisture, in some cases it even bloomed or overgrown with fungi. All this is due to attempts to reduce costs. To do this, use fewer disinfectants, a cheaper binder. Chinese manufacturers instead of pine chips put hardwood, which is easily affected by fungi and diseases.

Properties and specifications

OSB boards compete with other sheet materials both in the field of construction (for sheathing frames, creating formwork) and in the field of finishing (leveling walls, floors, ceilings). This is facilitated by the properties of OSB:

Once again, we draw your attention to the fact that moisture resistance and resistance to deformation are characteristic of OSB, which were made in compliance with the technology. Unfortunately the material Russian production is not different high quality. Less powerful presses are used, they try to save on the binder, do not apply markings. As a result, there are many examples of negative experience: plates swell from moisture, warp them, glue is washed out ... The way out is to look for plates of imported (Europe or USA) production. Due to the growth of the dollar, they now have considerable prices, there are very few of them on the market, but, if desired, you can find or order with delivery.

The situation is aggravated by the fact that in appearance it is impossible to distinguish moisture-resistant OSB3 from non-moisture-resistant OSB2 or 1. The latter cost much less. Unscrupulous sellers sell cheaper ones under the guise of moisture resistant ones. This is where trouble comes in. As a way out, you can do this: buy one sheet of OSB 3, check its behavior when high humidity. If there are no visible changes, buy a batch.

Application area

The properties of OSB make it possible to use this material as a building or finishing material. Here are the jobs it can be used for:

• Sheathing of frames and walls from the inside and outside.
• Floor and ceiling leveling.
• Flooring of a rough or finishing floor along the logs.
• Removable formwork when working with concrete.
• Solid crate under, metal tile, slate,.
• Production of SIP panels and thermal panels.

There is a constant debate among developers about how safe OSB is. In its production, resins are used that emit formaldehyde. Manufacturers claim that the release of this substance does not exceed 1%. Materials with such formaldehyde emission are considered absolutely safe. About the same amount of this substance emits wood. Therefore, such materials are allowed for the construction of children's furniture. In addition, OSB boards with an emission of 0.5% appeared. You can distinguish them by two criteria: the name contains the prefix Bio or Green and they are more expensive.

Please note that the level of formaldehyde emission must be controlled. Each batch of material must be checked, the actual parameters must be indicated in the accompanying documents. Despite all the arguments, not everyone considers this material safe, preferring to use natural material- boards. They are, without a doubt, an environmentally friendly material, but it takes longer to work with boards, they are more expensive. In general, everyone decides for himself whether to use OSB boards or not.

Dimensions of oriented strand boards

Since the purpose of the OSB board is different, different sizes can be convenient. The situation with the size of OSB boards is not easy. On sale there are constantly 1220 * 2440 mm and 1250 * 2500 mm. There are also formats 1250*2800 mm, 1250*3000 mm, 1200*6000 mm, but they are extremely rare on our market, although in many cases they are much more convenient to use. Picking up right size you get rid of the need to “grow” the missing centimeters or saw off the extra ones. But there are not so many of them on the market, since these are imported plates, and now it is difficult to import ...

The OSB board can also be of different thickness - 9 mm, 12 mm, 15 mm, 18 mm, 22 mm, 25 mm. Each type of use has its own thickness:

• Sheathing of walls, ceiling - from 9 mm.
• Solid underlay roofing materials- from 12 mm.
• An OSB board from 15 mm thick will go to the floor.

Another one of the applications of OSB boards is a removable formwork for concrete work.

OSB board - convenient construction material. It can be sawn regular saw on wood, use a grinder with cutting disc, jigsaw. The material is well drilled, screw nails can be used without pre-drilling. But then their hats stick out, which is not always convenient.

Before finishing, the OSB board is coated with a primer. It is selected depending on the finishing materials - to equalize the absorbency and improve adhesion to other materials.

Recently, oriented strand boards have gained popularity in construction. In Russian standards, this material is abbreviated as OSB, sometimes they are designated English letters OSB (oriented strand boards) or Russian OSB. We have already reviewed the main characteristics, brands and applications of these products in the article. . In this article, we will talk about how to properly work with oriented strand boards.

What is important to understand when working with OSB

First of all, when working with it is important to understand the principle of manufacturing this material. Structurally, the slab consists of chips (chips) that are oriented in a certain direction. All scraps have their own clear direction, the chips in each subsequent layer are located perpendicular to the next and previous ones. This is the key to the strength of OSB. Accordingly, depending on the direction, each oriented plate has a longitudinal and transverse axes. The longitudinal (main) axis has the highest bending strength, for the transverse (secondary) - these parameters can be two times lower. For this reason, installation should be carried out in such a way that the main load falls precisely on the main axle.

The internal structure of the material

In addition to strength characteristics and brand, it is important to pay attention to the quality of the chip material itself. According to GOST, wood chips have certain permissible parameters, their length cannot be less than 5 cm, and their thickness - 2 mm. If there are no large chips in the plate, and to a greater extent there is dust or sawdust, then the real structural properties of the material are reduced.

Problems of acclimatization

Before use, it is necessary that they undergo acclimatization in the environment where they will be used in the future. This is due to the fact that wood material has the ability to change its volume depending on humidity and temperature. Structural changes in OSB are greater than in plywood - depending on the brand, the material can swell from water by 15 - 25%.

Oriented strand board is divided into four grades. OSB-1 is a general-purpose material, designed for humidity not exceeding 65%, OSB-2 is used at a similar humidity level, but can withstand bearing loads, OSB-3 and OSB-4 are used in an environment with a humidity level of not more than 85%.

Acclimatization takes place over two days. The plates are installed in a vertical position, slats are placed between the sheets to improve air circulation. According to GOST, it is recommended that absolute humidity products ranged from 2 to 12%. At the same time, in unheated room the moisture content of the material can fluctuate at the level of 16 - 18%.

Particle boards must be protected from water even if OSP-3 and OSP-4 grades are used. Liquid contact will cause deformation and swelling of the material. After installation, the boards must be protected from moisture. facing materials(lining, siding, etc.). It is not recommended to treat the chipped surface with products with great content water. When using material for external walls, it is covered with a protective film so that the plates are not saturated with moisture from the ground, the sheets are laid on wooden linings. Also, with the help of wooden slats, you need to create air space between the film and OSB, again this is done for air circulation.

The ends are the most vulnerable places of the OSB, in the process of acclimatization when the environment changes from dry to wet, they can swell, in which case they must be sanded before installation.

cutting

Before installation, it is cut into sheets of different sizes. This can be done manually or electric tool. When working, it is important to exclude vibrations of the plate, so it is securely fixed with clamps. For sawing along a straight line, guides made of straight boards are used. When sawing, it is important to use a corner so that the cut always goes perpendicular to the border of the sheet.

When marking, it is necessary to take into account the thickness of the cut, for all tools it has its own. Before starting work, it is recommended to carry out a rough cutting of an unnecessary piece of material. Sawing oriented strand material should be done at a moderate speed, the forward movement should be done smoothly. Marking is done using a ruler and a construction marker. Due to the large dimensions of the sheets, they are installed on wooden stand, the cutting option is also allowed in vertical position. Consider the main tools that can be used for cutting.

• - for sawing OSB, a tool with a fine tooth is used. For serious construction work, a hand saw is not well suited, since the cutting speed rests on the physical efforts of a person. Completely refrain from hand saw also not worth it, it can play an auxiliary role when cutting small elements. For cutting OSB, a hacksaw with a fine tooth is best suited.

• - the tool can be manual or desktop. When working with the latter, the user himself pushes the plate onto a rotating disk. For sawing OSB, discs with large quantity teeth and soldering from hard alloys. Some circular saws have a nozzle for connecting a vacuum cleaner, which collects sawdust remaining from work.

• - easy-to-handle sawing tool various materials. The cut is carried out using the movement of the hacksaw blade. Some devices have a pendulum cut function, when the blade goes not only up and down, but also in the direction of the cut. Working with the device is simplified with a keyless blade change. Adjusting the angle of the sole helps to make difficult cuts in an inclined plane. For cutting large slabs, a jigsaw is less effective than a circular saw. The main inconvenience is the difficulty of an even cut.

Some manufacturers produce blades specifically for cutting wood boards.

Tightly - types of fasteners

Oriented strand board can be used in various construction areas. Fasteners vary depending on the application. Commonly used nails, screws, screws and staples.

• - fastener in the form of a rod, most often used for fastening the OSB to the external frame (during the construction of a frame house) and to the crate for the roof. In this regard, nails have a serious advantage over self-tapping screws, as they keep the plates from moving. The self-tapping screw will simply break off under the weight of the vertical plate, and the nail may bend, but will continue to hold the wall of the house. Best for working with flexible materials screw nails show themselves. Ruff and ring nails are also used, they are more common for roofing. It must be remembered that it will be difficult to pull out such nails. AT finishing works hardware with a small hat is used.

For fastening it is necessary to use galvanized fasteners so that it does not corrode.

• Screw connections- these include wood screws and. Fasteners are easily twisted and easily unscrewed without harming the material. Screw connections are used when fastening OSB to concrete using dowels (laying a subfloor on a concrete screed). Screws and self-tapping screws provide better tear-off fixation, therefore they are more often used on horizontal connections.
• Staples- mounts H shape used to connect the edges of the particle board on the roof. Pneumatic or electric construction staplers are used to fasten surfaces.
• Gluing is not used as the main method of fixation, more often the application of adhesives is used as additional mount when laying slabs on the logs. Usually any wood adhesives are used, they are selected depending on the method of fastening and the humidity in the room.

Mounting Features

Installation varies depending on the type of work. To general recommendations includes the presence of an expansion joint and protection against contact with water.

Compensation (deformation) seam- this element is called differently, in fact it is a regular seam. As we know from the characteristics of the material, OSB boards tend to swell, change their shape and volume depending on temperature conditions. During installation without an expansion joint, over time, waves and bumps appear on the surface of the plates. The seam between the plates should be 3 cm, next to the walls - 12 - 15 cm, to the foundation when mounting the wall - 10 cm. If the length of the mounted plane exceeds 12 m, then make a gap of 25 cm.

When installing grooved boards, the expansion joint is formed by itself due to the tongue-and-groove design.

Creation example expansion joints when installing the floor

Now consider the features of installation on specific examples.

• Subfloor installation- oriented strand boards are laid for subsequent placement of laminate or parquet on them. Installation is carried out on logs or on a concrete screed. The thickness of the sheet when mounted on a concrete screed is 8-10 mm; for the log, a plate up to 22 mm is required, depending on the distance between the supports. Fasteners are carried out on nails or on dowels with self-tapping screws, sometimes as additional funds fixing glue is used.
• Gender on strip foundation - in this case, installation is also carried out on logs from a bar, but at the same time, the OSB side facing the ground is processed. It is allowed to lay two layers of slabs, in this case they are laid "in a row" so that the seams are not on top of each other.

Features of the installation of a rough floor covering made of chip materials depend on the subsequent finishing. For example, tiles will require a solid base, so it is better to use tongue-and-groove designs when using roll material(carpet) gaps must be sealed with adhesive-sealant.

• - schemes are used in the ceiling, as well as when fixing the floor on logs, only beams are used for the ceiling. To ensure structural rigidity, the main axis must be perpendicular to the beams. The ceiling is covered with a waterproofing film to protect it from water, special holes are made to drain the liquid. Fixation is carried out on self-tapping screws, screws or nails.

Ceiling installation with OSB

• Wall mounting produced on the racks of a frame house. The task of the particle board is not to veneer the structure, but to give the structure rigidity and create the power circuit of the house. Fastening is carried out on three racks of the frame using screw nails, which are driven in around the perimeter every 15 cm, in the central part of the sheet - after 30 cm. With a distance between racks of 50 cm, 12 mm thick plates are used. The nail should be 2.5 times more thickness the sheet itself and driven in at a distance of 1 cm from the edge. So that water from the house does not condense on the insulation and on the stove, with inside material is protected by
• FROM outside The OSB is closed, it does not allow moisture from precipitation to enter the material, while allowing the wall of the house to "breathe", organizing air exchange inside the wall. Steam leaves the room freely, but moisture remains on the outside.

Multilayer wall of a frame house - "frame pie"

Such a structure is called the "pie" of the frame house. The main purpose of a multilayer wall is to protect OSB from condensation. Improper design leads to the development of mold and damage to the entire structure.

• - oriented slabs are the basis for the subsequent fastening of the roof, the sheets are installed on the truss system. The thickness of the sheet is selected depending on the step of the rafter leg. At 60 cm, it is optimal to use slabs with a thickness of 12 mm, at 80 cm - 15 - 18 mm, for a larger rafter pitch, OSB 22 mm is used. Fastening is made on screw nails, since shear fastening is important on a pitched roof. The longitudinal axis of the plates is perpendicular to the truss system. Between themselves, the layers of material are connected in two ways: tongues or staples. In the presence of a grooved connection, you can not make a compensation gap, otherwise the gap should be 3 mm, and fastening is done with H-shaped brackets.

When installing the roof, the slabs are laid with the rough side outward to facilitate the movement of builders.

Finishing

After installation, it needs final finishing. The material is suitable for wallpapering, puttying and painting. But for this, the surface must be prepared.

• Seam sealing- It is not necessary to seal technological seams. In most cases, they are covered with laminate, tile or any other outer coating. Sometimes sealing seams is even harmful. When using dry mixes during shrinkage, the plate may be deformed. For some types of work, it is still necessary to process the seams, for example, when painting, a 3 cm gap will spoil the appearance of the room, so the gaps are closed with a docking mesh, which is attached to the putty.

• Grinding- unpolished OSB has a not quite even texture. For coating with paints and varnishes, it is better to use polished material or process the product yourself using a tape or eccentric grinder. This procedure is especially relevant before processing the flooring, as it allows you to get rid of irregularities.

The plate of factory grinding in its marking has the letter Ш, unpolished products are indicated by the letter combination НШ.

• Primer- the simplest and universal way surface preparation for finishing. The primer is used before painting, before laying tiles, before using varnish, etc. For oriented strand board, primer mixtures provide protection against moisture and increase adhesion (adhesion to other materials). Antiseptic mixtures can also be used to prevent the development of pathogenic microflora; a primer is laid for the subsequent use of alkyd paints. For putty, soil is used.

• Reinforcement- the imposition of a reinforcing mesh for subsequent plastering, laying tiles or tiles.

Conclusion

OSB is a multifunctional material that can be used in various fields, the features of installation and processing depend on this, but there are also general principles chipboard work. Care must be taken to minimize contact with water. When installing walls, it is important to observe the correct design of the walls in order to avoid the formation of condensate. When laying slabs, one should not forget about the need for expansion joints.

OSB (OSB): features for working with plates and installation recommendations

The floor of OSB boards can be found quite often. In order to lay OSB on a wooden floor or walls, complex highly professional installation is not required, but care must be taken, as it is important not to miss a single moment in laying technology.

How to cover the OSB floor on logs and on concrete

Making OSB flooring is not difficult, and you can use the simplest panel. To make the floor device more durable, it is worth choosing canvases with grooves. The joints should be located directly on the logs, but if they are too large, then it is better to install an additional fastener. To put the OSB panels and make the floor on the logs, you will first need to prepare the necessary inventory.

Namely:

• Jigsaw;
• Drill;
• Roulette;
• self-tapping screws;
• Building level.

Between the bars there should be a distance of no more than 40 cm, and in this case, laying sheets with a thickness of 1.5 cm is acceptable. If the distance is greater, then the panels should be thicker. The distance between the boards is made the same, and it is also important to lay the plates correctly so that there is a small gap. The gaps will subsequently be filled with the most common mounting foam.

Making OSB flooring with your own hands is quite simple

If additional thermal insulation is needed, then foam plastic or the most common mineral wool can be used.

It is quite possible to lay OSB sheets on concrete screed, and for this it is worth following the sequence of actions. The foundation is being prepared. The floor must be carefully vacuumed so that dust does not cause poor adhesion between the canvas and the floor. Be sure to prime the surface of the concrete. As a solution, you can use any primer, even though deep penetration, even the usual one. Next, you need to cut the sheet, this can be done with your own hands. Be sure to take into account such a moment as leaving a technical gap near the walls, which should be equal to 5 mm. This is required in order to prevent swelling of the sheets with an increase in their size, which occurs when exposed to moisture. Direct installation is carried out using rubber-based adhesive and a driven dowel. Before laying the sheets on the concrete floor, you need to lay the insulation, and also make sure that the sheets are even and suitable for construction. Laying on the subfloor is not difficult, and it is possible to do everything yourself.

Benefits of floor panels

A building material such as OSB-plate has a lot of advantages, due to which many people prefer to lay it on the floor. The material is so high density that rodents cannot gnaw through the canvas, and harm its integrity. This finish is moisture resistant.

Accordingly, you can choose panels for:

• baths;
• Bathroom;
• And similar damp rooms.

The canvas has excellent pressing, and therefore even small scraps do not crumble. The product has excellent resistance to biological factors. The canvas is completely environmentally friendly, since natural wood shavings are used for the manufacture.

OSB-plate has a lot of advantages

It is not at all difficult to carry out installation even to concrete, even to another base, and professional training is not required.

The cost of the material is not too high, and one element has quite impressive dimensions, which means it can close large area. OSB excellent level reliability, which allows the highest quality to carry out not only finishing, but also construction. Due to good wear resistance, you can use the canvas for a long time and not worry about the formation of defects, since the material does not dry out. OSB is difficult to bend, easy to saw and replace with a new one.

Thickness and composition of OSB

The characteristic of the material means a lot, but when choosing OSB sheets, you also need to pay attention to such a criterion as the parameters and the manufacturer. When creating a finished floor, or perhaps it will be a substrate for a laminate on a balcony, you must always follow the recommendations from the finishing experts and then it will fully meet your expectations.

Masters with extensive experience with such canvases prefer to use panels of European and Canadian production.

When choosing OSB boards, consider them specifications and manufacturer

The choice of thickness is carried out according to:

• On which coating the panel will be laid;
• budget;
• operational properties.

As for the dimensions, there is only one standard, and it is 2.44x1.22 m. The thickness does not affect the dimensions, but yes, the quality of the finish. If you need to attach small pieces of OSB, then it is possible to cut the canvas at home, which will not cause much difficulty and problems.

Do-it-yourself budget OSB furniture

OSB boards are great as a kitchen decor, for example, for lining an apron or even creating original shelves. An openwork cabinet or a bookshelf in the office will look very unusual.

The use of OSB panels is very diverse, since the board can be installed as a partition between rooms, and also used:

• For the arrangement of the roof in a private house;
• For finishing the stairs to the second floor;
• as a cladding;
• Like a canvas to cover a warm floor;
• For making furniture with your own hands.

With the help of OSB-plates, you can make furniture with your own hands

Due to the fact that the plates are solid and will not warp, massive cabinets are made from them. Among the additional advantages, it is worth noting the presence of a decorative structure. Furniture is made simply, but it looks very unusual, and sometimes it does not even require additional finishing.

If you stick original pictures on OSB furniture, creating a Provence style, you can achieve excellent result and create an original interior with your own hands.

There are many options, but it all depends on preferences and opportunities. If desired, you can construct a whole children's town inside the house, but first you need to familiarize yourself with which screws will be used to mount it.

Proper installation of OSB on a wooden floor

Over time, any coating loses its aesthetics, and therefore, in order to close the old wooden floor, you need to lay OSB boards, and it is better if the board is moisture resistant. There are still such rooms in which the floor is not linoleum, but a wooden floor.

Many were in a hurry to put such a coating, since it:

• Durable;
• wear-resistant;
• Durable.

Before laying OSB-plates, it is necessary to prepare the subfloor

The principle of laying the floor in this way is not complicated. The foundation is being prepared. You need to make sure that there are no protruding nails. If during the period of operation the boards were not just deformed, but became uneven, then before the fastening is carried out, it is necessary to align. For this, a planer is used.

When laying out the cut sheets of OSB, one must not forget about the seams for shifting the canvases.

The fastening is carried out with self-tapping screws, the length of which is 4 cm. The fasteners are installed at a distance of 30 cm from each other. The hats must be recessed into the coating. After completing the work, you need to grind the joints of the canvas.

OSB panels should not be confused with material such as plywood, the front side of which is unlikely to surprise anyone. It is worth noting that you also need to correctly pronounce the name of this canvas.

Some misinterpret RSD as:

• WHISBY;
• YUIZBI;
• WESBY;

This is required so that the OSB panel is chosen to cover the floor or walls, since an incredible amount of building and finishing materials goes on sale, and it is not difficult to confuse them by name. The OSB laminated panel is laid on a self-leveling floor or concrete floor using compounds such as mastic or glue.

To fix the OSB-plate on the wall, you need a crate that is installed to the frame of the building

To glue the canvases together, that is, concrete and the board, you need a lot of composition, but how much is needed is calculated depending on the situation, since more solution is transferred to the porous coating.

To fix the product on the wall, you need a crate that is installed to the frame of the building. The installation of the plates itself is carried out with two-inch spiral nails 51 mm or annular nails 4.5-7.5 cm long. Drive-in is carried out every 30 cm into the supports at intervals. Where the plates are connected, nails must be driven in every 15 cm. In addition, care must be taken to leave expansion gaps so that the installation is as correct as possible. A space of 1 cm should be left between the edge of the slab located at the top and the crown-type beam. 1 cm should also be left between the edge of the slab located at the bottom and the foundation. There should be a distance of 0.3 cm between the canvases that do not have grooves.

In some cases, the decoration of walls sheathed OSB panels, is not produced in the future, since rooms with such a finish look very unusual. The most common way to decorate a canvas can be called puttying, as it is not only a finish, but also an additional sealing of cracks and joints. High-quality puttying allows you to get a perfectly beautiful room. If necessary, putty can be painted, covered with wallpaper or any other finishing materials.
