OSB Plate 01/05/2017

OSB plate

In modern finishes, widely used for different materials, including traditional, who have long been firmly occupied its position in the market of building materials. One of them – OSB-plate, sizes and prices are diverse.

When the need arises to produce construction or finishing work, it immediately raises a problem: what material to use. After all, the work must be done securely, and the design last a long time. We should not forget about financial investments, they must be fully justified. Therefore, increasing use is OSB plate, which has many positive characteristics.

Any construction – an extremely costly exercise. It is felt by each who began the construction of their own home or just doing repairs. Significantly reduce costs, will allow OSP stove, the demand for which in Russia is rising every year.

What is an OSB?

What is an OSB?

What is an OSB?What is an OSB?It is oriented strand Board, that is, the material that is created on the basis of wood chips. It can be small or large, but in any case, the material is durable and dense thanks to the combination of several layers. Chips in the layers is then transversely, then longitudinally, making a sheet of OSB is stronger and more reliable in operation. Itself wood chips created from different materials – wood of coniferous or deciduous species.

In production, only carefully selected high-quality chips. In the plate it is also a special way: first it is placed in the perpendicular direction, in the middle is a parallel layer, and the top chips again placed across (of course, with respect to the axis of the OSB itself). This approach allows to obtain a thin and extremely durable material, which in most cases can be done even overlap.

In addition, molded wood OSB under high pressure and temperature, using a special synthetic resin. All this gives a ready-made material has excellent characteristics: it is strong, resistant to mold and mildew, extremely durable. It is not surprising that the OSB Board reviews, where we look at odds in recent years, increasingly large quantities.

This material has some features and therefore are in high demand among buyers due to several characteristics:

  • Light weight. This advantage is especially important if you plan to mount the roof space under the tiles.
  • High reliability, which is confirmed by numerous studies and experience in practice.
  • Moisture resistance. This figure suggests that plate swaps can be used for furnish of premises with high humidity level, maintaining their operational properties for a long time.
  • Low cost. This factor attracts many, because at an affordable price, the material has a sufficient margin of safety and quality.

Disadvantages of OSB-plates is small, and the most important is the low fracture strength. But this feature is common to almost all sheet materials.

Classification

Classification OSB
  • OSB-1. The material has a low resistance. Used for minor works.
  • OSB-2. Suitable as a cladding of load-bearing structures, but only in dry indoor rooms.
  • OSB-3. The most common type that can be used for finishing and construction works. Maintains good interaction with the humid environment. But prolonged exposure leads to a gradual warping.
  • OSB-4. The most sustainable option. But there is one drawback – high cost.

The most demanded is considered to be the OSP-3, which has the best ratio of price, quality and performance.

Now a lot of talk about the harm OSB. Indeed, the binder are formaldehyde resin with additives. But modern technology makes the material completely safe for humans. Although the selection of plates it is necessary to pay attention to the certificate of conformity.

About the water resistance

About the water resistance

About the water resistanceAbout the water resistance OW now also available in OSB moisture resistant. Not to say that it could withstand the year-round stay in the pouring rain, but the reviews are encouraging. In particular, some owners were built of moisture-proof plates outbuildings. As their experience shows, even after five or six years, no signs of damage and delamination of the material is not observed.

And all of this material varies in moisture resistance. There are plates of strong moisture resistance (they can and should be used outside of buildings) and average moisture resistance (typically used in finishing the interior of buildings).

Strong moisture – contains adhesive which is substantially pervious to water, such plates are used for exterior walls, also on these boards put the shingles, they keep water and a little wet. If you immerse them in water for 24 hours, this material will swell by about 15 %. Moreover, the stiffness and design practically do not lose their properties.

Average humidity – then the adhesive is weaker, but can also resist moisture, although slightly worse. Swells up to 20 – 25 %. But it is cheaper. However, if you trim the inner premises, such plates can be very useful.

Dimensions

In different variations on the market of OSB-plate. Sizes and prices allow you to choose the optimal solution for a specific task. It is noteworthy, but the manufacturers from different countries offer different sizes of plates. To the standard include the following:

  • 2440×1220,
  • 2500×1250,
  • 2800×1250,
  • 3125×2000.

This is the most popular among buyers in size, but in reality they are much more, so the choice should be guided by it.

Features of production

Features of production Features of production

Features of the production OW each country has its own regulations, according to which are made of different building and finishing materials, including OSB-plate. Specifications, the price of the material as a result of this approach vary. To us, this material is mostly imported from Europe and North America, where production of OSB is based on the relevant standards. But some companies have their own separate certification, with the result that the final material has its own marking.

Specifications of OSB-plates have the following:

  • Simple installation.
  • Compliance with environmental standards.
  • The homogeneity of the structure, which is able long to save your settings.
  • High resistance to aggressive environments and humidity.
  • The use of cladding, which will have a high density.
  • Minimum waste during operation.
  • Additional strengthening of the structure of roofing systems and walls.
  • Aesthetic surface.
  • Etc.

Manufacturing technology

Technology of production of OSB involves several stages.

Sorting

In the manufacture of osb in the course is only a small tree. Sawing the trunks in size to the individual elements, and then the workpiece is passed through a machine processing them in the bonded tape. After the material is in the process of drying in the special bins that use waste generated in the production of chips. After that it is sorting the chips into small and large.

Mix

The selected material is mixed with the binder. This is necessary to ensure product durability. The mixture is then fed into drums, where it is optionally mixed with paraffin and resin.

Forming and laying

This process of production of OSB material is held in a special unit, equipped with pressure rollers, weights and magnets, the latter is necessary to search for a mixture of foreign metal occurrences . At this stage, the orientation of the chip in different directions.

Pressing

There is a seal bonded carpet, with a gradual increase in temperature to values of 170-200 . The process is the use of steel tapes. They are lubricated with thermal oil and heated in the boiler, the capacity of which is less than 8 MW.

Debugging

As a result of this production we get a long sheet moving along the conveyor. At this stage it is checked for compliance with the geometric characteristics and cut at the required length. To give to completely harden the resin, the finished material is kept in warehouses.

Advantages

Advantages

Advantages OSBAdvantages OWASP has virtually no cons, but the pros have plenty of it, will list again the points:

  1. Do not lose the geometry with time. Not the "sit down" like a normal wooden house.
  2. Durable. If further treated by special trains, moisture resistance and fire resistance will increase significantly. Thus, the service life of the plates will increase significantly. As the manufacturer we assure to 300 years and above.
  3. Good resistance to moisture
  4. Holds screws and nails (almost like wood)
  5. Very eco-friendly.
  6. Easily handled – can be cut, planed, drilled using conventional tools for wood
  7. Easy to finish – can be painted (paint lacquers), plastering, brick tax etc.
  8. You can apply from the outside
  9. High strength. For example in Japan during the earthquake, the houses using OSB boards were less affected than houses made of wood and brick.
  10. Aesthetically pleasing, can be painted and nothing to decorate.
  11. Good flexibility
  12. Quick installation.
  13. Good soundproofing

As you can see the OSB plate of very high quality material, and their use in the construction of frame houses is justified. Prices at the moment in Russia range from 400 to 700 rubles per sheet.

Sustainability, or how OSB safe for the health?

Sustainability, or how OSB safe for the health?

Sustainability, or how OSP safe for the health?Sustainability OSBOSB plates are used not only for external but also for internal furnish of premises. Still some debate on the topic of how the material is harmful to health. Opponents OSB argue their position by the fact that the manufacture of the material manufacturers used formaldehyde impregnation. Therefore, the operation must inevitably stand out of the fumes dangerous to human health. But is it really?

In General we can say that all depends on the manufacturer and its approach to product stewardship. OSB plate may have four options of eco-labeling: E0, E1, E2, E3. Despite the fact that the plate class E3 contain up to 30 mg of formaldehyde emission per 100 grams of material, and the plate is E0 class — only to 6.5 milligrams, the maximum allowable standards for harmful fumes does not exceed any one variety.

Exactly the disputes around this issue are almost as long as this material appeared on the market. Most of our consumers at the word "chipboard" just remember the product of Soviet times. Used in their manufacture synthetic resins contain such a quantity of phenol that diseases of the respiratory tract caused by the constant presence in the homes with such furniture, met very often.

However, the reviews of current customers indicate that no adverse effects from the use of this material is. It's all in the production of the plates: use the special resin, which contains almost no harmful substances. Many people have second or third decade living in houses from OSB, but no problems noticed.

You can only make one comment. Given that the production material is still used synthetic resin, warmed by the sun, the attic (if you have one) should be frequently ventilated. The fact that in the first years of operation may appear not too pleasant smell. Sometimes it's not always and not everyone, but bear in mind this circumstance will not prevent.

Where is it used?

Where is it used?

Where is it used OSB?Where is it used?OSB is a material which due to universality is used in different industries. In the construction industry it is useful to apply when installation of the roof sheathing, paneling, laying of roofing materials – slate, shingles or metal. Wide size range allows to apply the material and for finishing rough floor, when laying slabs on load-bearing joists or solid surface. It is possible to use OSB for the installation of single-layer floor which is subsequently covered with materials such as linoleum, carpet, floor boards. It is possible to use varieties of OSB Board for the walls in the construction of interior partitions, installation of the removable casing. A range of applications underlines the versatility and practicality of the OSB-plates.

The same material is used in the manufacture of packaging. It is used in the production of such works as:

  • The production of pallets and crates.
  • Temporary closure of openings in buildings.
  • Repairs: ceilings, partitions, the laying of the floor.
  • Concrete and reinforced concrete works, as a reusable formwork.
  • The erection of structural elements in low-rise construction.
  • Device solid sheathing a pitched roof.
  • The covering frame walls.
  • Covering the floor and walls in vans and trucks and many others.

Features of installation

Features of installation

Features monthspecial advise you to pay attention to the carpet tiles have passed acclimatization. The essence of this process is to equalize the humidity of the finishing material and the humidity of the environment where it will be used. Particle Board should be stored properly, away from moisture. After completed its installation, from the outside, i.e. on the walls, the roof, facades, require additional insulation, which would protect them from high humidity. Particular attention should be paid to the edges – it is here that concentrated the high humidity, under the influence of which the edges will start to swell. Excessive moisture can be associated with the following reasons:

  • Installation on a surface that was not properly dried or "wet" processes.
  • Improper installation of insulation materials, whereby the inside of the structure is exposed to water.
  • Use for the finishing of unseasoned materials.
  • Defective protection against the impact of negative natural factors.

Features of OSB

Features of OSBHere you can to arm themselves by any means and ways, so it's all good: the use of cutting tools and drills of all types and hand-held power tools. When anchoring you need to consider a few things:

  • The nails used are the same as those for the installation of solid wood.
  • If you use for fixing brackets, they must be not less than 1.5 mm in diameter with a length of 50 mm.
  • The mount runs from the middle top, and then moving towards the sides and down. These actions are not accidental, because thanks to them, the plates will swell and SAG as the operation.
  • Special nails increases the strength of the connection.

Recommendations for installation of OSB boards

Recommendations for installation of OSB boards

Recommendations when installing OSB will platamona in the draft, you cannot make multiple changes if it was not originally created for use OSB Board! In any case, the number of joints should be reduced. But to dwell on it it is in any case impossible. The forums are full of stories about how the outcome of the project was delayed because of similar thoroughness for months.

Generally, too much focus on independent processing of projects is not necessary. The fact that no serious result can be obtained only if you do mass building. And the reviews on the forums say the same thing: the panel should only be used in those areas for which their strength is sufficient.

After studying the reviews you can come to a simple conclusion: if we are able to do without cutting – do without it. If something goes wrong, it is better to cut the desired piece than a clock to crawl on a newly built house with a tape measure. In the end, cut OSB-plate can be a simple manual hacksaw, and it takes a couple of minutes.

Recommendations for installation of OSB boardsSo, we would not advise to order projects reduce the cost of specialized companies, since the effect will be very little. In this case it is easier to order a ready-made drawing of the house in which OSB-plate. Its application in this case is greatly simplified.

Modern finishers suggest to buy OSB-panels for decoration as the floor and walls. But the installation in each case has its own characteristics. So, when you create "floating" floors need to pay attention to the joining material and walls between them left a gap of less than 15 mm. If the slabs are sheathed walls, the gap between the panels and the Foundation retained in the 10 mm. If the installation is conducted over a large area (more than 12 m), then for every 12 meters should be left expansion gaps with a width of 25 mm. They are needed to ensure that the slabs did not appear waviness or other undesirable phenomena.

If OSB panels are used for finishing wooden ceiling on the first floor, the mandatory installation of the waterproofing layer: it protects against humidity. Most often chosen film, which is easy to install and easy to operate. Installation of flooring using the plates requires a stacking of load-bearing boards, pillows, which will become a sound insulation layer and will absorb the sound of footsteps.

If mounted "floating" floor, this design will include one or two plates, but to make the surface uniform, enough for one sheet material. When installing OSB on the walls to do this either horizontally or vertically, making sure that the dimensions of the plates coincided with the height of the walls. In case of horizontal installation the main focus is on joints and free edges that are complemented by strips of plates or stiffeners. Load-bearing walls can be lined with slabs on both sides – external and internal.

If mounted under the roof structure, then you first checked the location of the rafters on the axes – they should be smooth and not vary in size. In the case of curvature, the roof will be uneven and unsightly. Connection plates made so that all faces are perpendicular.

Possible swaps

In fact, all types of OSB are becoming increasingly popular. Therefore, their scope is not only limited to finishing or construction activities. Several options for alternative use:

  • The production of interior items. In particular furniture. For the most part, it frames for sofas and armchairs. Although there are options for basic products.
  • Various types of containers. It could be a packaging for the transport.
  • Finish of vehicles. Most often truck trailers.
  • A material like OSB is the key to successful construction. But many people mistakenly believe that there is an opportunity not to follow the rules and technology. OSB – facilitates process, but does not make him less responsible.

Useful tips for optimization

Useful tips for optimization

Useful tips for optimization OSBUseful tips on optimizaciya mentioned above, the most common is the optimization of the model projects under the OSB-plates. Although it is not too welcome, but there are a few ways that help to optimize the project with minimal losses and maximum efficiency. Consider the most effective of them.

As we already said, the standard panel should be joined and cut as normal ceiling height (2.5 m) more sizes of plates. Much better to put the panels on edge. Since the plate-bonded OSB has a standard width of 1250 mm, it will be possible to use a smaller number of joints, which will increase the strength of the structure as a whole. The builders are self-taught, who independently built their house on this technology, talking about a substantial reduction in the amount of waste.

Properly calculate the window!

In addition, from the reviews you can understand that to a significant reduction in the cost of construction (less construction materials consumed) leads competent calculation of the size of the window lintels. The builders give you an example: if you take the ceiling height is 2.8 meters, the window opening better to do with width of 1250 mm and height 1400 mm. In this case, the installation of OSB-plates is so precise that you can place the solid panels on the walls, without making a single incision.

If we cut the panel lengthwise, obtaining two pieces of 900х1500 350х1500 mm and mm, we get two perfect blanks for window units with a height of 150 cm. simply put, when selecting measurements, based on the characteristics of your existing material, you can almost completely get rid of the waste and scraps. In principle, the feedback suggests that the panels do often cut it into two parts.

Cut right!

And there is a logical explanation. For example, the standard unit is divided into 625х1500 mm. Given that the height of the walls of the attic often is just 1.5 meters, it is possible to easily assemble the room, not sharing the material on the extra pieces. However, builders also point to the fact that we should not forget about the standard measurements of project you plan to "adjust" to fit your needs. Explain on more simple example. Suppose you want to make these plates home, which in the original project has a size of several hundred square meters, but still stands on two or three floors. Don't do that! This material is intended for the construction of houses in a maximum of two stories tall (and better half), so as to further load the strength is already sufficient.

More tips

Remember, in project, you cannot make multiple changes if it was not originally created for use OSB-plates! In any case, the number of joints should be reduced. But to dwell on it it is in any case impossible. The forums are full of stories about how the outcome of the project was delayed because of similar thoroughness for months.

After studying the reviews you can come to a simple conclusion: if we are able to do without cutting – do without it. If something goes wrong, it is better to cut the desired piece than a clock to crawl on a newly built house with a tape measure. In the end, cut of OSP-the plate can be a simple manual hacksaw, and it takes a couple of minutes.

Generally, too much focus on independent processing of projects is not necessary. The fact that no serious result can be obtained only if you do mass building. And the reviews on the forums say the same thing: the panel should only be used in those areas for which their strength is sufficient.

So, we would not advise to order projects reduce the cost of specialized companies, since the effect will be very little. In this case it is easier to order a ready-made drawing of the house in which OSB-plate. Its application in this case is greatly simplified.

Other

The builders themselves also say that we should never forget about the width of the used panels and in the case of installation of the exterior walls. In our case it is 1250 mm. If the walls of the house 5x5 meters, the whole plate to use will not work. But at 5,125 5,125 m fit perfectly and cut you will have much less. From the people who were engaged in construction of such houses, one can often hear feedback about that on the panel drawings, it is desirable to draw the rectangles: so you'll be able to pocitat their number.

By the way, how much is OSB-plate? The price depends on the manufacturer and type of the panel, but most often does not exceed 700-1000 rubles per share.

Butt gaps, as practice shows, can be neglected. Accuracy of manufacturing of the panels is not so high that the three to four millimeter would be possible seriously to navigate. Note that when cutting this amount of material is also reduced, and when using saws with large teeth is the most noticeable.

In General, OSB-plate, whose thickness is about 8 mm, not prone to swell, so that misalignment of the design because too small gap will not. However, you still not it should be possible to tightly join the panel, as the technological gap between them should be present in any case.
