OSB plate - reviews. OSB-plate - price, characteristics

Construction - employment is very expensive. This is immediately understood by everyone who undertook the erection of his own house. Of course, there is always a desire to cut costs as much as possible, but not at the expense of the final quality. That is why the plate OSB is so widespread recently. The testimonies indicate that it is an excellent alternative to many traditional building materials.

What it is?

By the way, and what kind of plate is this, what is it so good? Object-oriented slab (OSB) is called a variety of particle-board materials. Unlike the banal chipboard, it has some features. First, tight control over the quality of wood chips, which distinguishes the production of OSB-plates from the release of conventional chipboard.

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

In addition, the OSB wood board is formed under high pressure and temperature, using special synthetic resins. All this gives the finished material excellent characteristics: it is durable, resistant to mold and fungus, extremely durable. It is not surprising that the OSB stove, the reviews we will be considering, diverge in recent years in ever larger batches.

About moisture resistance

At present, the OSB plate is also moisture resistant. It can not be said that she could withstand the year-round stay in the pouring rain, but the reviews are encouraging. In particular, some owners erected homemade edifices from moisture resistant slabs. As their experience shows, even after five or six years no signs of destruction and delamination of the material are observed.

Is this material safe for health?

Disputes around this issue have been going on almost since the material appeared on our market. Most of our consumers at the word "particle board" immediately recall the products of the times of the USSR. The synthetic resins used in their production contained so much phenol that respiratory diseases caused by permanent exposure in houses with such furniture were very common.

Do not worry! Reviews of modern buyers indicate that there are no side effects from the use of this material. The whole thing is in the production of plates: a special resin is used, which practically does not contain harmful substances. Many people have lived in houses from OSB for the second-third decade, but they do not notice any problems.

Only one remark can be made. Given that in the production of the material still use synthetic resin, the sun-warmed attic (if you have it) should often be ventilated. The fact is that in the first years of operation, a smell is not very pleasant. Sometimes it is not always and not at all, but keep in mind this fact does not hurt.

Practical examples and feedback. Construction of houses

Construction of houses from this material causes a lot of fierce disputes, in which even professional builders sometimes take part. Since the interest in the topic is largely artificially heated, the discussing experts sometimes turn to personalities. But communicating on the forums is by no means the best way of drawing up your own opinion about the prospects of the OSB. To do this, you need to talk to practitioners.

What are their feelings about the OSB plate? The testimonies show that professional builders stand on the side of using standard blocks. Thus, the maximum permissible size of the slab can not exceed 1.5 meters. Alas, but this is what causes the main stream of criticism: whatever one may say, one has to make walls with at least one joint. Practices such "dockings" are advised in every possible way to avoid.

This is due to the fact that in extreme cases the plate has an extremely high load. Consequently, the probability of damage is high. Many owners of out-of-town houses that used this solution during construction, just as they complain about broken and damaged sections of the slabs. It does not add much decoration to the house.

Approaches to construction

So what is the OSB plate suitable for? Reviews say that this material is ideal for the construction of small country houses. The main thing is not to forget to provide normal airing in the dwellings. The builders themselves say that at present there are following approaches to the construction of OSB panels:

• In the first case, just choose any favorite project at home, after which it is adapted to the existing realities.
• The second approach is much more pragmatic: a specialist is hiring a project that takes into account all the strengths and weaknesses of the material.

Alas, but the most common is the first way. Our builders are constantly looking for approaches to reduce the cost of the project, so nothing good does not end there. It is often possible to meet reviews of disgruntled buyers who complain about the poor quality of this kind of designs. Houses can sink, wall structures are often skewed. As you might guess, the economically distressed customers are to blame for this.

A little about the cost

Strangely enough, but specialized design in practice is much cheaper. The builders themselves explain this simply: the fact is that the architects immediately calculate the necessary amount of materials and make an estimate of the project, which in practice does not change in any way. Feedback indicates that with the adaptation of the project, no more than 48% of OSB panels can be used. If specialized projects are used, it is possible to take up to 80% of this material.

In this case, the OSB-plate, the application of which we are considering, is extremely economically profitable.

Do not repeat other people's mistakes!

Of course, with the desire to save many, they are trying to draft themselves. But on this way they are trapped by many pitfalls. If you try to make maximum use of OSB-plates, then as a result you will get a big, beautiful, but ... barrack. In addition, the standard technology leads to the fact that the houses acquire an absolutely identical appearance, and some architectural features are completely replaced by "cubic" building.

By the way, many new homeowners are complaining about this circumstance: they do not like that many thousands of almost the same houses can be found all over the world.

Apparently, this is built only because of the entrenched opinion that the "Canadian" construction technology assumes exclusively direct forms and the simplest form of houses. In fact, this is not due to technology. Simply, developers do not "bother" with something more complex, but use the simplest forms and technological solutions. If you build a house for yourself, you can make it out of OSB-plates, but give it any shape.

Anyway, the article has a photo. OSB-plate on them looks quite "plastic" material, which can be given almost any shape.

Useful optimization tips

As we already said, the most common is the optimization of standard projects for OSB-plates. Although this is not very welcome, there are some ways that help optimize the project with the least loss and maximum impact. Let's consider the most effective of them.

As we have already said, standard panels will have to be joined and trimmed, since the usual ceiling height (2.5 m) is larger than the slab size. Where better to put the panel on the edge. Since OSB chipboard plate has a standard width of 1250 mm, it will be possible to do with fewer joints, which will increase the strength of the structure as a whole. Self-builders who independently built their homes on this technology, say a significant reduction in the amount of waste.

Competently calculate windows!

In addition, from the reviews it can be understood that to a significant reduction in the cost of construction (less spent building materials) leads a competent calculation of the size of the window lintels. Builders give an example: if you take a ceiling height of 2.8 meters, then the window opening is best done with a width of 1250 mm and a height of 1400 mm. In this case, the installation of OSB-plates is so accurate that it is possible to place entire panels on the walls without making a single cut.

Another variant

If you cut the panel lengthwise, getting two pieces of 900x1500 mm and 350x1500 mm, you will get two ideal blanks for window blocks with a height of 150 cm. Simply put, when choosing the measurements based on the characteristics of the material available for you, you can almost completely get rid of waste and cuttings. In principle, the testimonies indicate that the panels are generally cut into two parts.

We cut right!

And that is a logical explanation. For example, the standard block is divided into parts of 625x1500 mm. Given that the height of the walls of the attic is often just 1.5 meters, one can easily arrange the room without dividing the material into extra pieces. However, builders also note the fact that you should not forget about the standard measurements of the project that you plan to "fit" to your needs.

Let's explain it with a simpler example. Suppose that you want to make a house from such slabs, which in the original project has dimensions of several hundred square meters, and even rises to two or three floors. Should not be doing that! This material is intended for the construction of houses with a maximum of two floors in height (or better - one and a half), since in the future the load-bearing strength is already insufficient.

More tips

Remember, you can not make multiple changes to a project if it was not originally created for using OSB slabs! In any case, the number of joints should be minimized as much as possible. But do not get hung up on this in any way. The forums are full of stories about how the development of the final project was delayed because of such scrupulousness for months.

After studying the reviews, you can come to a simple conclusion: if you get by without cutting, do without it. If something does not work out, it's better to cut off the desired piece than to crawl for hours on the house under construction with a tape measure. In the end, it is possible to cut an OSB plate with a simple hand hacksaw, and take it away from the force for a couple of minutes.

In general, too much to get involved in the independent processing of projects is not worth it. The fact is that a serious result can be obtained only if you are engaged in mass construction. Yes, and feedback on the forums say the same: the panel should be used only in those areas for which their strength is sufficient.

So, we would not advise ordering projects of cheaper in specialized companies, since the effect will be quite a bit. In this case, it's easier to order a ready-made house drawing, which will be based on an OSB-plate. In this case, its application is greatly simplified.

Other

The builders themselves also say that you should never forget about the width of the panels you use and in case of installing external walls. In our case this is 1250 mm. If the walls of the house are 5x5 meters, then one-piece slabs can not be used. But 5,125 at 5,125 m is ideal, and you will have to cut off much less. From people who have independently built such houses, you can often hear testimonials that on the drawings of the panel it is desirable to draw in the form of rectangles: so you will be able to accurately estimate their number in advance.

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

The joint gaps, as practice shows, can be neglected. The accuracy of the production of panels is not so high that these three or four millimeters could be seriously oriented. Note that when cutting this volume of material is also reduced, and when using saws with large teeth it is most noticeable.

In general, the OSB-plate, whose thickness is of the order of 8 mm, is not inclined to swell much, so that there will be no skewing of the structure due to too small a gap. However, you do not need to dock the panels as tightly as possible, since the technological play between them must be present in any case.
