OSB plates are a relatively new building material that is widely used during construction and repair work. One way to use it is to use as an outdoor coating. Due to its properties, such a coating has high strength and low weight, it is moisture-resistant and has a low price, all this explains the growing popularity of the specified building material. In order for the floor, covered by OSB, has a long service life, the material fastening must be carried out correctly.

OSB stove inexpensive, high-quality material for flooring. It is durable moisture-resistant, light.

Features of choice

Now there is a large selection of OSB, which are characterized by their properties and characteristics.

In order to make the right choice, the following recommendations must be followed:

• the most qualitative products are considered to be products of Canadian and European manufacturers, it is issued according to modern technologies and meets the E1 standard (environmental safety);
• it is best if laying (fastening) OSB-3 is carried out on the floor;
• by concrete coating, it is necessary to use plates with a thickness of up to 10 mm, for the wooden coating, their thickness depends on the distance between the lags.

The size of the standard OSB plate is 2440x1220 mm, so the required number is calculated on the basis of the location, to obtain a minimum of waste. With the help of a circular saw, it is easy to cut the necessary size, to use an electrolybiz is not recommended for this, since it is not always possible to get a smooth slice.

OSB laying on concrete floor

If the concrete floor is in your room, then the fastening of the OSP as an outdoor material is an excellent solution.

After an OSB is laid on the concrete floor, you can install finishing materials: tiles, linoleum, laminate, parquet board.

The main functions of the OSB on the concrete floor:

When calculating the number of plates, it is necessary to consider that losses when cutting the plate are 7-10%.

• alignment of the imperfection surface of the floor, on which there are usually irregularities, height differences and other defects;
• reliable sound insulation, which is ensured by a multi-layered material structure that allows you to absorb various noises well;
• waterproofing and insulation of the floor. The specified material has a natural basis, high heat-saving characteristics and moisture resistance.

If there are significant boosts of concrete coating, the fastening of the OSB plate is not immediately on the floor, but on wooden bars who play the role of lag.

To ensure maximum stiffness and resistance to deformations, it is better to use OSB-plates with a thickness of 8-10 mm, laid in two layers. We need to lay layers with displacement, they are attached to each other with the help of spiral nails or glue.

If the concrete floor is even, then the OSB can not be laid directly, in this case there will be a single layer, it is fastened using self-tapping screws or dowels. Although the material and moisture resistant, there is a partial absorption of moisture, and it expands slightly. To compensate for a possible expansion or compression, it is necessary to provide dilatation gaps between the plates of up to 3 mm.

Processing Material

OSB Plates can be used as an independent floor covering, and you can use it as the basis for laminate, linoleum or parquet.

This coating can be used and independently, it is cleaned for this, and then several layers of varnish are applied to it.

If there is a laying of rolled materials, it is necessary to ensure a smooth transition in the joints of the joints, the plates take the minimum thickness. The gaps try to do from the walls of the wall, they are treated with elastic sealant.

To cover the floor with a tile, the base must be completely fixed, so the OSB must be put especially carefully. The tile is put on special glue, which provides a reliable compound of ceramics and wood.

Laying plates for laminate does not imply special requirements, only in the joints of the joints should be perfectly smooth.

The floor from the OSB is now enjoying great popularity. It has a lot of advantages and makes it possible to reduce the repair period. OSP is a strongly pressed plate, which consists of several layers. Raw materials for the production of this material are long chips (6-9 cm) obtained from coniferous wood rocks (pines, sometimes aspen). OSP strength is provided by various chips orientation. For example, in the middle it is placed perpendicularly, and in the extreme layers - along the length. Pressing is performed under the influence of high temperature and pressure. At the same time, the impregnation of the material with resins and waxes, which ensure its moisture resistance.

OSB has such advantages:

• and processing.
• During the sawing or drilling, the sheet does not begin to crumble.
• No blocking during operation.
• Uniform structure.
• Very high strength of sheets that can replace even wood materials. Note that the material can withstand enormous loads if they are distributed correctly.
• No bitch.
• High degree of resistance to moisture.
• A long service life is about 20 years.

As you can see, the OSP is an excellent material for the arrangement of both rough and finishing gender.

Production of OSB Plates and Application for flooring for lagas

Types of material

Before you start working with sheets, you need to figure out what they happen:

1. OSB - 1. This is the least durable and thinnest plate. It can only be used in those rooms where the air humidity is never observed.
2. OSB - 2. Such sheets can be applied to arrange the supporting structures only in dry rooms.
3. OSB - 3. This material is well suited for the arrangement of carrying structures in those rooms where the level of humidity is often high. This type of product is used in the construction most often.
4. OSB - 4. Such sheets must be treated in those rooms, where a very strong mechanical load is assumed to the floor. The thickness of such a plate is maximum. In addition, the material is carefully processed by wax and resins, so moisture is completely not afraid.

OSB comparison with other wood materials

Specifications

Before buying an OSP, it is necessary to consider its technical parameters:

• Resistance to moisture: Depending on the type of coating, this parameter varies in 12-25%. The most sustainable moisture is a stove with the smallest indicator.
• Mechanical strength. The most reliable can be considered the plates 3 and 4th grade. In general, the strength of the product along the transverse axis ranges in the range of 1200-1800 N / triple, as black2, and along the longitudinal axis - 2500-4800 N / mm2.
• Mass of the product. One stove can weigh from 12 to 43 kg.

Characteristics table OSB-3 with different stove thickness

• Material thickness: 0.6-2.2 cm.
• Environmental purity: According to laboratory studies of different organizations, the content of harmful components in the product does not exceed the permissible limits.

The cost of the plate depends on its technical parameters and is 420-780 rubles. a piece.

How to choose a product?

Before rolling OSP, it is necessary to decide on these parameters:

1. Type of base. The thickness of the material depends on this.
2. Product size.
3. Required qualities (for example, if you will install an OSP in a dry room, then you may not need such quality as resistance to moisture).
4. Manufacturer. It is best to give preference to European, Canadian and North American manufacturers. Their products are certified by international organizations.

Application of OSP for finishing and black floor finish

OSP - 3 is most often used to arrange floors.

How should the material for different types of flooring?

Floors from OSB can be black and finned. In the second case, the surface is simply grinning and varnished. Naturally, the slots between the sheets should be invisible. If you decide on top of OSB to install another facing material, then the base must be pre-prepared depending on what kind of coating you will apply:

• . The base should be smooth, especially in plates connections.
• or . In this case, it is better to use thin plates, which will make the transition between them smooth and almost imperceptible. Additionally, it is processed by a sealing agent. Note that if one sheet of OSB is stacked on the floor, the compensation clearance is equipped with walls.
• . Choosing such a facing material, it is necessary to take into account that the basis for its laying should be as strong as possible and smooth. Sheets should be fixed so that they are fixed. If you are fine OSB on lags, then in this case they should be mounted at a short distance from each other.

Features of the installation of rough base

So, if you decide to apply OSP plates for roughing equipment, you need to decide on what you will lay them: concrete or wooden lags. In any case, the most acceptable material will be an OSP - 3. If the base for installation is a concrete screed, then the sheet thickness may not exceed 1 cm. In case of laying on wooden lags, this parameter can reach a maximum - 2.5 cm. To concrete, the material is attached at Aid dowels. You can lock it on the tree with the help of self-tapping screws. Note that the fasteners hats need to be dragged into the stove. Thus, you will achieve perfect surface evenness. If you need to achieve maximum strength of the base, then the sheets should be laid in 2 layers. At the same time, the seams in the lower and upper layer should not coincide.

During the installation, pay attention to the quality of the joints. They need to be aligned as much as possible and smooth. This uses an elastic sealant. The arrangement of rough floors is made like this:

• For starters, lags are mounted on the floor.
• Now you can fasten additional bars (at the bottom). Their section should be 5x5 cm.
• The party that will contact concrete or facing the soil should be additionally processed by an antiseptic or bitumen mastic (just one layer).
• Fastening plates. This can be done using special nails, screws or glue.
• . It can be a foam or mineral wool. Between the stove and the soil, you can also pour clairzit.
• Laying an additional OSP slab, which will serve as a base for subsequent cladding.

Cake of draft floor from OSB plates

Before laying the first layer of sheets, it is necessary to produce water waterproofing.

It is possible to sharpen the material on a dry tie. The saturation must first be aligned under beacons. Next, it is necessary to mount the OSP layer, on top of which the same sheets are added, only with the displacement of the seams. You can fix them using self-samples, the step between which is 15 cm. Note that the fasteners must be screwed along the edge of the second layer.

You can entrust the gender device to craftsmen, professional builders. They will make the floors quickly and efficiently. True, far from cheap. You can save, no flooring on your own. Moreover, the device of the floors does not represent anything particularly difficult. It is only necessary to carefully study the technology of their laying and apply the knowledge gained correctly in practice, in a certain sequence. Below we will tell about how to make floors from the OSP itself, choose the material that the tools will need, the works that need to be executed.

OSP is, say, sandwich, which can consist of 3 or more layers. Two (upper and lower) layers are pressed plates made of wood chips. The chips are laid along in the outer layers of the plates and across the inner. Therefore, the stove is generally called oriented-chip. The chips can be impregnated with boric acid, wax, formaldehyde resins. There is a insulation between the layers, which can be used polystyrene foam, as well as polyurethane foam.

OSP is used mainly in the construction and manufacture of furniture. Marked and is used as follows:

• OSB-1 - for the production of furniture, packaging or plating surfaces;
• OSB-2 - in dry rooms for the device carrying structures and surfaces;
• OSB-3 - indoors with high humidity;
• OSB-4 - for structures that are subjected to large loads, as well as located in places where humidity is raised.

OSP can be lacquered on the one hand coated with a laminate, whipped or from two, or from four sides.

The stove is a rectangle with the following dimensions:

• thickness from 8 mm and up to 38;
• length - 2440 mm;
• width - 1220 mm;

Above, we led the size of the standard stove. Sometimes you can find an osp with dimensions - 1.25 meters by 2.5.

Advantages of OSP are as follows:

1. low cost;
2. low weight;
3. easy and well processed;
4. durable;
5. resistance to moisture;
6. does not succify, not resolve, does not rot;
7. it does not start mold and insects.

Unfortunately, there are restrictions on the use of OSP. When pressing the chips is impregnated with resins that contain toxic substances. They constantly allocate the volatile compounds of these substances into the environment. Therefore, choosing a plate, you need to pay attention to how many of these substances is released by a brand of the slab, and in which area it is allowed to apply it.

Installation of floors

There are two types of sex floors. The first consists of a concrete screed, waterproofing, intermediate black floor, the OSP itself. The second type is waterproofing, lag, preferably a draft floor, OSP.

Materials and tools

Plate is better to buy a tipped. From two opposite sides, there should be a tongue, and from other two - grooves. This slab is easier to mount.

Laga is a bar. In the construction for the manufacture of lags, they are mainly used with sizes of 5 to 5 centimeters or 5 to 7. The number of lag depends on how the sexual coating itself will be arranged. If the draft floor is not, then the number of lag increases.

Price for bar

If you plan to put the floor on the screed, you will need a rake, because directly on the screed, even if it will be laid waterproofing, it is impossible to lay the slab. Any wooden product should breathe, that is, to choose the air and give the accumulated moisture. It is for this that makes the gap between the floors and the tie. Otherwise, from the moisture accumulated in the product, and the tree and so kept moisture in yourself, and also absorbs from the screed, it will begin to hide and, in the end, will be unusable, as if qualitatively it has not been done.

For the draft floor, a edged board or plywood can be used, the OSP itself.

For the manufacture of the screed, you will need cement brand of not less than M-300 and sand. The solution can be prepared by itself, but it is easier to purchase a ready-made sandy-cement mixture in the store. Consumption per square meter. m. indicated on the package. The concrete mix, which includes a filler, gravel, crushed stone and the like, at home should not be done. Manually stand the high-quality concrete solution do not prepare.

For a better and smooth floor fill, there will be beacons.

In Russia, a plinth is installed on the floors. It also serves the detail of the decor, and closes the gap between the wall and the floors. The gap is made specifically, based on the expansion of the board with a rise in temperature. If it is not planned, you can do without a plinth.

The stove is usually bonded with a bar of nails and glued with glue. So we need and glue, and nails. When installing the floors use screw nails or self-tapping screws.

For sealing, the slots will need a putty on a tree. So, there will also be needed to the spatula. It will be needed a wooden hammer, a molding of plates, a metal hammer.

Floor mounting stages

All laying of any sex is divided into three main stages:

• preparation;
• main works;
• cleaning.

The last stage is known to everyone. Therefore, we will not consider it.

Preparatory stage

In the future, all reasoning we will lead, bearing in mind that the installation of floors is made in a residential room. In the utility rooms or buildings, the floors are stacked as well as in the same sequence as in the apartment. Only restrictions are less and the requirements below. All stages we will break at the stage. We call them steps and present our reasoning in the form of a step-by-step instructions for the performance of work.

So preparatory work.

Step one. Select the type of floor. That is, we will define whether we will lay it on the screed or on. If you choose lags, it is better to first make the drawing of their location. It will help correctly calculate the number of lag.

Outdoor boards thickness, mm	Gap between lags, mm
20	300
24	400
30	500
35	600
40	700
45	800
50	1000

2nd step. We calculate the volume of work, make up cost estimates.

3rd step. We make purchasing materials. By purchasing a slab, we definitely pay attention to the fact that it corresponds to sanitary standards. Lumber, a blackboard under the draft floor, a bar, a rail, it is advisable to buy already dried and treated fire and antiseptic means. If you cannot buy such a sawn timber, you will have to buy an antiseptic and process wood yourself.

4th step. We cultivate the plate, clean the burrs, irregularities from the edges. The sawn timber process the antiseptic and fold on drying. It is stacked by layers. Gasket is made between the layers. It is needed so that the material is breathing, sucked evenly and quickly. Dry wood for at least a day. The temperature during drying should be +10 degrees and above.

5th step. If the floor stacked for the first time, the garbage remaining after construction work is removed.

If the OSP is filling instead of the old floor, then old in the case, of course, when it cannot be used like a draft. Disassemble the floor must be carefully so as not to damage the plaster on the walls. To do this, take out nails and remove the board, then remove the lags. Semi rake (each) free from the grooves, we move towards and removing.

6th step. We establish beacons to level the floor level. Not less than three marks on each wall. Between them carry out a line. Between the wall and line, zero at any point is reported to show an angle equal to 90 degrees.

Installation of floors

If the floor is mounted on the screed, We will have to fulfill several actions.

1. Install the beams under the fill of the screed. The distance between them should be no more than 50-60 cm. So the screed will turn out to be more even. Check the installation of lighthouses by the level. If there is a bias, align.

2. Cooking the solution. It should not be too liquid and excessively dense. Plive the place prepared under the screed, recall the solution with the rule with mounted beacons.

3. After the screed grabbed, check its level. If there are irregularities, slopes, pour an additional layer of the solution to align it.

If the screed turned out to be smooth, then on top of it lay waterproofing. You can use a simple runner or any other material designed for these purposes. On top of the insulation we put the rail. We would advise to put it and along and across, in the form of rectangles, which are combined. Thes of them must correspond to the size of the plate or be slightly smaller. Rake wrapped glue.

Also allow installation of plates without the use of rails. In this case, the rubber glue is asking a concrete screed.

4. On the rail to put the stove. We take a queen and knock down the plates as close as possible. The punch must fully enter the groove. Ideally, the gap between the plates should not be.

5. We fasten the slabs with the rail with nails or self-tapping screws.

6. If there are cracks, we close them with glue or putty on the tree. It must be selected in the color and texture of the slab. Save putty 24 hours. After putty dry, it needs to be seized twice. Large skurt for the first time and shallow in the second.

If OSP is stacked right on the lags, then install them better along and across. The fact is that OSP is a comprehensive construction and is unknown, as it will lead after heel, dyeing, shrinkage. And laying of lags in the form of rectangles will reduce the load on the slab itself and reduce the likelihood of defects. All other actions that will need to make exactly the same as when installing the floor on the screed.

Let me give you one advice. The best, in our opinion, the device of sex floors is a design that provides for the installation of an intermediate black floor. It will give all the floor additional strength, stability and significantly reduce the load on the coating itself, i.e. on the stove. As an intermediate floor, you can also use the slab itself, and the plywood, and the old floor. But the latter can only be used in the case when it is well preserved, and there are no serious defects on it. You need to remove all the old paint, align, close the cracks. Scratches, pollute, process an antiseptic and only after these preparatory work can be treated with a slab. Actually, on the plywood, and on the OSP, which will be a draft floor, you also need to close all defects and cracks. The remaining actions on the laying of the first floor we have already described above.

OSB plates are very popular thanks to its characteristic, therefore have very wide use in construction. Depending on the thickness, the stove can perform a carrier function even in a wet room. OSB plates consist of laid, ordered fine particles of wood held by a binder. In this step-by-step guide, we will show you how the OSB laying is made correctly.

Since the composition of the OSB plate is such that all elements are laid in one direction and beautifully aligned, OSB even in the untreated state looks harmonious and partially even modern. In addition, the modern development of technologies in industry makes these panels are particularly strong and resistant to the external environment. Thus, the OSB panel is used for different purposes. Thin options for OSB plates are used to build partitions or wall decoration, also for cladding the pitched roofs. Thicker plates are used to arrange floors.

Instruments:

• level
• folding line or roulette
• pencil
• forceps
• screwdriver
• manual Circular
• a hammer
• laminate styling bracket
• electropolitanzik
• japanese Pila
• oSB plate with grooves
• film for waterproofing
• adhesive aluminum ribbon
• substrate for noise insulation
• rule
• klinia

If the floor is placed by a floating manner, this means that OSB floor plates should not be attached to the base, but only with each other. This prevents the creaking of the floor, which often occurs when the floor is made of wooden elements in the room where the constant change in air pressure and temperature. However, if the floor is placed in a floating method, it can always be freely stretched and shred in the direction of the walls, without making annoying sounds.

Benefits OSB-Boards

Manufacturers of this material produce plates in four classifications. The first OSB - 1 is the panels that are used for the manufacture of furniture and interior wall decoration are suitable only for use with reduced humidity.

OSB - 2 is used in dry rooms, but already has carrier properties.

OSB - 3 plates are stacked in wet rooms as base. They are ideal for floating laying on an attic or concrete surface.

The fourth class OSB, these are panels that can provide strong properties of properties in all areas, even in a wet room, like for example, bathroom. These panels can be used if the beams in the attic cost enough from each other, this will allow you to create a durable floor. If the distance between the meter beams and more, then it is undoubtedly necessary to use OSB - 4. Starting from the distance from the beam about one meter, you must use these panels anyway.

OSB 3 - universal floor option

OSB of the third grade is the perfect option for flooring in your home. The material has many positive properties, but pay attention to the weight of the sheets. If you want to make the floor on the second floor or attic, lift yourself on the height of this material will be complicated or not even possible. Depending on the thickness of the slab, the weight can be from 590 to 610 kilograms per cubic meter.

Sizes plates that are on sale

• Plate size with groove and spike 2500 x 625 mm-12, 15, 18, 22 and 25 mm
• Size with straight ends 2500 x 1250 mm - 8, 10, 12, 15, 18, 22 and 25 mm

Preparatory stage

Tip: Optimal is the choice of not only thicker OSB plates - a size of 22 or 25 mm, but also, if possible, made by m grooves and spike for the connection. Thus, you will get a higher floor strength that will withstand large weight loads.

Before starting work, check the beams and boards for damage caused by worms or rotting. If you put a new floor, you will no longer have access to these elements at home and the possibility of changing something or change.

Tip: When buying glue, pay attention to the note: glue without formaldehyde. This is an more environmental option, and it must be taken even for non-residential premises.

Paul alignment

The old floor or concrete floor served for many years will often be a bit uneven, so it is necessary to align it before laying the OSB panels using the leveling layer. Otherwise, the slabs will be fed or saved over time. Perhaps even with a strong load on the floor, they can break.

Now in every economic store you can buy various mixtures, including clamzit or something like that.

Before aligning, you must install guides that fall asleep with bulk material and are aligned with rule or high level, or finally flat board. At the end, you need to make sure that everything is aligned in terms of level and tightly laid, without holes and protrusions.

When aligning you need:

• small grains or leveling mixture
• guides
• rule
• level

Especially if the OSB laying is carried out on the old floor of wooden boards, vaporizolation is required between them. It is just a durable polyethylene film that you stick aluminum adhesive tape. The film must speak well on the wall, to later it was above your new floor from OSB. After completion of all works, the film will be hidden behind the plinth.

Laying soundproasting

If you do not install the OSB on the first floor, then additionally you need to put a sound insulation material. Otherwise, your walking on the floor will be very audible in the room under you. Soundproofing for sale both in rolls and small mats, it is not very expensive, so it is not necessary to lower this step.

Plate laying - first row

Before laying the OSB panel, should have time to adapt to room temperature, as well as laminate or parquet. Therefore, it is recommended to store plates indoors at least 24 hours before stacking so that they can acclimatize.

Stacking Start with the longest wall wall - from the left corner. At the slabs that fall to the wall cut the lock from the wall - with the help of a circular saw. The sheets are then aligned along the wall, at a distance of about 80 centimeters, the wedges are installed on each other - between the plates and the wall to set the gap from 1.5 to 2 centimeters - this is a temperature seam.

Tip: If you want to glue the floor, you first need to crop all sheets for one row, and then apply a thin layer of glue to the junction of the groove and the lock. Using the rail brackets, the plates are shifted to each other.

The last sheet in the first row should usually be cut. In order for the seams of plates not directly in one row, the cropped plate is used as the first element in the next row. Thus, a composition like a brickwork is created. Always use a sufficient number of wedges so that the floor is clamped from all sides.

If the remaining leaf trim, which falls in the next row less than forty centimeters, it is better not to use it, but find a more suitable half of the sheet.

Frozening and cleaning from glue

Leave the floor alone at least 24 hours so that the glue can dry. Then you can remove the wedges near the walls. If the OSB will not fit the finish coating - laminate, parquet, linoleum, etc, it should be painted or apply wax for wood.

Tip: Use good quality wedges, preferably plastic. Wooden wedges are partially splitting already at the first right blow hammer. And soft fibers cannot retain a large floating floor.

In the attic, where they do not live constantly, you do not need to worry about installing a floating floor, here you can simply fasten sheets to the base.

If possible, drill holes for screws and walk through the holes of the zenker. Thus, the screws will be recessed in OSB sheets, and you can't hurt their shoes.

Tip: If the room does not heal, you should use screws that are not rust due to high humidity. Ideal for this purpose, stainless steel screws, because they can be unscrewed even after several years of operation in a humid environment.

Double flooring from OSB

In the case of not very strong base from rotting boards or beams or with a large distance between them, experts recommend using two layers of OSB plates. For example, leaves with a thickness of 10 or 12 millimeters are screwed down the first layer, and then in the opposite direction the sheets of thorough - 8 millimeters are attached. At the same time, it is necessary to carefully ensure that the stoves will never coincide.

The additional advantage of this method is the price, since the sheets with direct end cost less, and a small thickness of sheets - still saves money. Although the floor in this version will turn out to be thinner than floating - but it will be significantly stable and stronger.

For many floor coverings, a smooth base is required. One of the possible options is the floor from OSB. It can be done by lags, on the draft floor, put on the concrete. It is only necessary to choose the right class, the thickness of the material and comply with the installation rules.

OSP is a sheet finishing and building material. The above name consists of the first letters of the full name: oriented chipboard. That is how it decrypts. But the name of the OSB and the Latin OSB is also found (sometimes the USB is also said, but it is completely from another opera is the type of port in computer technology). Latin name is the first letters from the English name Oriented Strand Board. Translated the same as the Russian name. And the option of OSB is simply transliteration (replacement of Latin letters in Russian) from English reduction. Both options are eligible, but more correctly, after all, OSP.

Composition and properties

OSB is made of long chips (6-9 cm) of coniferous trees, which is mixed with resins and synthetic wax. The percentage of binding substances is low - 5-10% of the total mass. Small sinters and wood dust, from raw materials for OSB should be deleted. This increases the strength and flexibility of the material, but increases its value. Therefore, more expensive material of the same brand can be more practical.

What is OSB (OSP) - Materials from wood chips with resins

It is the binders - waxes and resin - give increased moisture resistance to the material. In the basic version, this sheet material is already with increased moisture resistance (it is better to carry moisture than, say, moisture-resistant plywood). Waterproof OSB has practically zero water absorption. On the one hand, this is good. Such a material serves as protection against moisture penetration. On the other - not very. There is no possibility to remove moisture from the room if the humidity has become elevated.

To increase strength and elasticity, material makes multi-layered. It can be seen on the cut and the ends of the slab. In the outer layers, the sins are placed along the long side of the plate, in the inner side - across. It makes it much stronger. In addition to high strength and water resistance, OSP properties are:

• Does not rot.
• It almost does not swell in water, after drying, retains the form.
• Do not amaze fungi and mold.
• Bad burns.
• High degree of elasticity.
• Good sound insulation features.
• Easily cutting.
• You can paint any paint, use varnish.
• Sheets can be glued.

All these properties together with a low cost make this material popular. What can limit demand - allocation of formaldehyde. This substance is contained both in the wood itself (natural content) and in the binder. To use indoors, take the materials, the formaldehyde emission class not higher than E1. It is absolutely safe material that can be used even for children's and medical institutions.

Classes, dimensions, marking

OSB was invented in Canada, gradually appeared on the market of other countries. With low weight, the material has high strength, which makes it popular in frame construction. There are two classifications of OSP plates. According to the European EN 300 there is a division into four classes, which are distinguished by the degree of water resistance:

The third class is most often used. It has a sufficient level of strength and moisture resistance, both for use inside and outside. If you want to make the floor from OSB, look at the plates of this class. If you prefer to have a margin of strength, put the fourth grade. But find it is not easy. Due to high cost, it is infrequent.

Plywood OSB - classes and basic characteristics

Sometimes in our market you can find an American oriented chipboard. They have another classification. It can approximately relate to European so:

• Interior approximately corresponds to OSB2. Can be used for internal works in dry rooms.
• Exposure 1 - according to the characteristics similar to OSB3. Wet conditions withstand briefly, so that they can be used in wet rooms or for outer decoration, subject to subsequent installation of moisture-resistant finish.
• Exterior - analogue OSB4 for a frame of a frame outside.

With the American and Canadian OSP (OSB), too, everything is clear. If you want to take the floor from the OSB, take Exposure 1. It, by the way, is usually better quality than domestic.

What is better - osb or plywood, osb or fiberboard

Which of the sheet materials are better, we will talk about the use of OSB (OSP) for the floor. If we compare the Fiberboard and the oriented chipboard, then the last material is better to take on the floor. It is less severe, more flexible. Compared to plywood he is cheaper. In general, it is difficult to compare with plywood, since this material, depending on the technology (glued or bakelite) and the original wood (coniferous or birch), has very characteristic characteristics.

What can be said unequivocally:

• Fasteners in OSB holds better. 25%, if compared with coniferous plywood, and as much as compared with wood-fibrous plates.
• If moisture, the OSB almost does not swell. After keeping in water 24 hours its dimensions increase no more than 10%. In this she is definitely better than plywood and chipboard.
• After drying, the plywood and fiberboard is stratified, begin to crumble. For OSB this is not observed. It dries and looks just like before.

If they are based on these properties, the floor from the OSB will be more reliable. Water on the floor is not so rarity. So it is important. And formaldehyde is present in plywood, and in the chipboard. And it can be neutralized using Vasilol primer. It absorbs formaldehyde and partially binds styrene. For complete safety, it is possible to add the scene, which absorbs styrene. An additional plus is becoming a complete non-combustible material - for wooden and frame houses it is very important.

Paul from OSB in Lagas: Sheet thickness and installation pitch Lag

When the floor is lagged, it is not necessary to reduce the boards on them. You can use sheet material. As an option - Paul from OSB on lags. The sheet thickness is chosen depending on the footage steps: the more often the bar is, the less plate thickness requires:

• Step Lag 40-42 cm, the stove must be at least 15 mm thick. If high load is planned, it is better - 18 mm.
• Lags are installed after 50 cm, the stove thickness should be 20-22 mm.
• The timber is fixed in 60 cm increments, it is placed with a thickness of 23-25 \u200b\u200bmm thick.
• If the varnish floor lie on the lags, it is possible to put sheets with a thickness of 10-12 mm.

Specific value from the range, we select depending on the planned load. For example, for giving, where massive furniture is not foreseen, you can take a fond (from the plug, which is given for each step of laying lag). For the home of permanent residence, it is better to take it thoroughly than then thinking how to eliminate savings.

As you understand, any of the options can be implemented - with any distance between lags. How to choose? For considerations of savings. Count for the price. For strength and reliability, they will be equivalent, but for the price they may differ. In each region, the situation with the prices for materials. Somewhere there are plates, somewhere a bar can be bought inexpensively. So consider each of the options and, on the basis of calculations, make a choice.

What else can you be guided when choosing a step lag? The size of the OSB sheet - the joints of the slabs should fall on the bar. Therefore, the distance between them is selected so that both plates rest on the beam.

What highlighter should be lags under osb? Depends on what properties should have the floor. If you need additional insulation and sound insulation, then in the intervals you can lay the appropriate materials. In this case, the height of the lag is selected depending on the thickness of the materials. If you make the floor from OSB on lags in the apartment, for sound insulation, under each lag it is worth putting a segment of vibrational foam rubber. The same gaskets stick to the ends that go to the walls. Rubber can be bought in auto shops, it is sold by strips pasted on a sheet. There are several such strips with glue to the lower part of each reference bar. This will help make you practically inappropriate for neighbors from below, as well as significantly weaken the noise, which are transmitted through concrete structures.

OSB Laying: Mounting Rules

Although the OSB changes the dimensions slightly, there is still thermal expansion. Therefore, when laying sheets in the room, we comply with such rules:

Under the soft coatings (linoleum, carpet, vinyl tile), seams should be filled. To preserve the elasticity of the compound, an elastic sealant is used, which, after drying, "does not finish".

How and how to fix OSB to lags and boards

When fastening plywood, the OSP to lags can be used selflessness or grown nails. For greater reliability, fasteners are sometimes lubricated with glue (universal). What is preferable, nails or screws?

So more reliable and convenient is the fastening of OSB on high-quality screws. But this is if there are no time limits and by price.

Fasteners are installed along the perimeter of the sheet and in the intermediate beams (if any). Step is not normalized. Focus on sensations. But mandatory fixation of the corners, and then, along the long side, they put fasteners with a step of 40-60 cm. Here, by whom it is determined by "reliability".

OSB laying features on wooden floor

If there is a boardwall, which you want to cover with another flooring, you need to align it. For this, leaf construction or finishing materials are laid on the wooden floor. One of the options is an OSP. On the boards, you can put too thick sheet - 10-12 mm is already enough.

First, the boards align, eliminating irregularities. Then put OSB plates. They are located so that the long side went across the boards. The laying rules are the same as described above. Sheet joints should be on the board, and preferably on her middle.

If the lags already lies some other material - boards, plywood, dvp - you can put the OSB on top. In this case, the sheets must be positioned so that the seams of the lower layer do not coincide with the joints of the top.

OSB on concrete floor

Concrete is a solid foundation, but very cold. And another ordinary screed is rarely perfectly smooth, so it must be aligned. Sometimes over time, cracks appear in the screed. They should also be closed, since the finish coating should not be put on such a base. There are two ways. The first one to put lags to concrete, the gaps are filled with insulation, and on top of the OSB or other sheet material. This option is correct, and it is described above. But sometimes even those 5-8 centimeters to steal from the height is impossible, as the ceilings in the rooms are low. Then you can do wrong - put the OSB directly to the concrete.

Put on the concrete floor of the OSB plate - this is not a completely correct definition. Rather, do not put it, but glue. Acrylic glue is used (not for tiles, but simply mounting universal glue). When choosing the composition, pay attention to it to be compatible with concrete and wood, and brands can be different.

How to glue OSB on concrete

The glue is applied to the base, pass the toothed spatula with a tooth of 4-6 mm (you can and more, but the consumption of glue will be greater). The height of the tooth depends on the size of the irregularities that are available. The height of the tooth should be more than 2 times than the amplitude of irregularities. But such an alignment will work only if the difference is not more than 4 mm. With more significant irregularities, it is necessary to either pour an aligning screed, or to grind already existing, removing the most significant protrusions.

Before laying OSB, concrete is ground. It is possible by the same glue, diluted with water, can be other acrylic soil. If necessary, you can find soil with water-repellent properties.

Plates are put to the walls not close, but leaving the gap of 5-8 mm to compensate for thermal expansion. The same clearance is left between the plates. So that the perimeter does not remain empty space, the foam of the foam of the suitable thickness is rolled under the wall or sliced.

To make it easier to withstand the gaps between the plates, the gaskets of the suitable thickness can be used. As an option - crosses for laying tiles. After laying each sheet, we definitely check its horizontal, control the level with adjacent sheets. All of them must be at one height.

If in the future there will be a soft flooring (linoleum, carpet, vinyl tile), the seams should be seen. They are filled with elastic sealant.

Note! It is important that the sealant after drying remains elastic. Then he will perform the role of the compensator. Otherwise, it will simply be reassigned.

OSB as a finishing floor covering

Sometimes there is not enough money to the finish floor covering. In this case, the floor from the OSB can be left for some time without finishing finish. But if the slab does not cover anything, in the field of intensive operation, the chips can go. That this does not happen, it should be covered with varnish in several layers. Varnish choose at your discretion, but note that the layers should be at least two. The form is quite normal, although not "suite."

Lacuation consumption on the floor from the OSB is very large. Moisture plate does not absorb, but the lacquer goes like a sponge. To reduce consumption, the chipboard is better for starting to predict. Select the primer under the selected varnish. And it is better to cover twice soil. Lacuation consumption will still be large, but significantly lower than without impregnation.

Another point. If you use an unlightened OSB, the surface may be uneven. This is characteristic of not very high-quality plates. If you lacquer without preparing, it will take a lot of varnish. If there is a grinding machine, emery paper with medium or small grain, you can remove the protruding parts, go through the vacuum cleaner, then the primer and then lacquer. If there are no grinders, when buying plates, please contact the surface quality. If possible, take, after all, polished OSB.
