Very convenient and multifunctional material for different construction work– oriented strand boards. Since the production technology of these plates is not complicated, for internal finishing works the master can choose a specific option from four types OSB boards or consider special types of these boards.

What are the sheets of these products made of? Everything is simple - wood chips are used (flat fragments are used), shavings: these materials are glued together and the result is really excellent finishing material. Three or four layers of chips or shavings – these are the indicators that can be called optimal. Installing OSB on walls is more preferable than using the same chipboard.

However, oriented strand boards are a kind of modification of wood-fiber material, some of its modern analogue. If finances allow, it is better to choose for facing works after all, OSB (plywood or chipboard are increasingly being abandoned today).

Scope of OSB, classification of boards

Before considering the classification of slabs and deciding which is the best OSB for finishing walls, it is important to pay attention to the characteristics of such a material.

Types of OSB boards

Here everything is as follows:

OSB boards first class - they are usually chosen for rooms where there is a low level of humidity;
Type two - the material can be safely chosen for dry rooms, it is even used as a structural element during construction work;
Type 3 OSB – these boards are used in rooms where there is a high level of humidity;
The fourth type of such products is used for cladding structures that can cope even with significant mechanical loads. Moreover, we are talking about conditions where there is a high level of humidity.

Application area

One thing can be said about the scope of application - installation of OSB is a truly urgent task, since such boards are used in many construction aspects.

It’s just that this material has such a manufacturing technology, due to which all internal defects are simply eliminated (at the same time, Chipboard sheets they appear very often - voids, uneven fillings). Due to all this, OSB is a more preferable option - it does not deform and does not shrink.

And now in detail - where exactly can this material be used??

Often for walls OSB sheathing is a very profitable solution. Due to this approach, the house receives reliable protection from dampness, and also acquires additional insulation. What's best here: there is no need for additional finishing work after installing OSB;
In the construction of frame-panel houses, OSB boards are usually used, which have high level moisture resistance;
Since the material has such valuable quality, it makes a decent reusable formwork;
It is used as a base when making external cladding walls, as well as internal works– if wooden finishing is carried out country houses, cottages (made of timber, rounded logs);
OSB boards are your faithful assistant if you are making sheathing or rafters for the roof. This material can work even under serious load - it will definitely withstand the weight of not only the roof itself, but also all accompanying loads (wind, snow) - even if natural tiles (a material that weighs nothing) are laid on the roof;
If you need to level the floors in your house or lay them from scratch, here again you can pay attention to the installation of OSB. It’s just that such a slab is an ideal option for creating a very strong, even base. It’s better not to find it under plank floorboards, carpets or other coverings;
Pay special attention to the process when you need to adjust the joints of the slabs to a plane. If necessary, they must be equalized - without this there is no way.

An interesting point - not every manufacturer can use OSB boards as underlying layers - in case of organization floor coverings. And the panels are laid so that the smooth side is facing up.

What else does a master need to know?? Following:

Apply additional protective covering it is not necessary in the form of paint or varnish - the material initially has excellent protection in the form of a special impregnation;
Processing slabs is not that difficult - about the same as regular wood. Screws and nails adhere perfectly to the surface. OSB boards are not afraid of rotting, fungal influences, the decorative qualities of such material are excellent;
OSB panels today are often used in furniture production - after all, they are an excellent alternative to natural solid wood (but in terms of cost, they are significantly more profitable);
The material does not weigh that much - therefore it is perfect for finishing, construction, painting works and not only.

How to finish a house faster

It is quite logical that any owner wants to move into his home faster - especially if the construction is carried out independently. Private cottages are located separately from neighboring buildings - so in this design you don’t have to worry about neighbors.

Here a completely justified question may arise: maybe you shouldn’t do the rough sheathing - but immediately attach the finishing OSB materials directly onto the frame posts?

Is this approach to the matter allowed, or is it excluded?

If you pay attention to the instructions compiled by professionals, it will immediately become clear: you cannot do this. There will also be reasons for this conclusion. Simply, it is important to insulate the house - only in this situation will it be comfortable (especially since winters in the Russian Federation are cold - almost throughout the entire territory).

Why are frame bevels required at all - lower and upper? Everything is simple here: they form spatial rigidity - together with the cladding. They can also be called mandatory elements if we consider the design of any frame structure.

A frame that does not have slopes will retain its mobility even with cladding - as is the case when there are any. However, if there is no cladding, you can imagine what the consequences may be.

External rough wall cladding

Today a lot of materials are used for rough cladding. different materials. There is definitely a choice here - everyone will agree with this. Pay attention to at least these options:

Board;
OSB boards.

Any of these surfaces needs finishing: this could be facing with plaster - with a mesh or a layer of polystyrene foam. There is an opinion that even the boarding can be left as a finishing touch - but in this case the wood will need to be processed additionally. Hydro-wind protection of the walls is also installed under the boards.

You must take into account the following: it is not recommended to finish the frame with boards - without rough, preliminary covering with OSB boards. Otherwise, there is a risk that the boards will come loose in the fall or spring. In addition, this is important for the spatial rigidity of the frame.

You will get fewer joints due to the area of OSB sheets - which cannot be said about working with other materials. OSB finishing is usually made with a material whose thickness is 11-13 mm.

Let's take a closer look:

The OSB boards are fastened to the racks so that there is a joint in the middle. And there should be a small gap between the plates - three to five millimeters is enough;
The sheet completely covers the lower trim;
The top frame is closely related to the number of storeys of the house. It will be completely hidden - and the edge of the OSB slab will be aligned with the edge of the trim if the structure has only one floor;
When a building consists of two floors, the sheet is positioned as follows: it must fit onto the racks of both floors at once. But somewhere in the middle of the sheet the top trim overlaps. This condition cannot be called mandatory, but if it is met, the rigidity of the structure increases noticeably, which benefits the structure;
Sheathing with OSB boards when fastening to a window opening is carried out in two-story houses, should be produced in a single sheet - this is exactly what the professionals advise. Then all the joints can be moved to adjacent racks outside the racks of the opening. They simply cut through the slab window hole– there is nothing complicated in such work;
When horizontal or vertical jumpers are made in the frame, the result is a very convenient joining of the slabs. In the event that these jumpers have the same cross-section as the racks - and this often happens;
Spiral nails are selected for fastening. Self-tapping screws are also suitable - 0.5 or 0.45 cm long. You should also not refuse combined fasteners (both nails and self-tapping screws) - such a solution is considered to be of very high quality.

Remember that basic rules When performing fastening work, it is imperative to comply.

Namely:

It is customary to fix the finishing of OSB slabs in intermediate areas every 300 mm;
After 150 mm, fix the places where the slabs are joined;
After 100 mm it is necessary to sew the outer edge.

To prevent cracks in the material due to too zealous fastening, a distance of 1 cm is maintained from the edge of the slab to the place of fixation (a little less is possible).

A gap of 4-5 millimeters is left between the plates so that they do not warp. The fasteners are driven 4-5 cm into the rack;
The part of the OSB board that is vulnerable (one might say this is the “Achilles heel” of the finishing material) is the ends. To ensure the protection of these areas, gaps are provided, which are called expansion gaps (between the crown beam and the upper edge, also between the foundation wall and the lower edge). Here the gap will be 10 mm. And between those slabs where there is no tongue-groove, 3 mm is quite enough;
To seal these expansion gaps, apply a sealant to acrylic base. It is important that it carefully fills all the cavities - and that this work is done evenly;
Wind protection, waterproofing - all these tasks will be performed by a superdiffusion membrane, which also has the property of vapor permeability (this indicator is 750 g/m² or more).

Use polyethylene various films, glassine - not recommended by masters. It’s just that these materials have a low level of vapor permeability; all excess moisture must be reliably ventilated.

Also, you should know:

The superdiffusion membrane is installed depending on the rough lining with materials, what it is fine finishing. For example, the membrane is often attached closely to the insulation - to the frame studs;
They make a sheathing (here they use wooden slats, the cross-section of which is 2 by 5 or 3 by 5 cm. Thanks to this design, it will be achieved required clearance. Then you can finish the surface with OSB boards, SML, DSP or sheathe it with boards;
From the inside of the room, you can use film to create a vapor barrier for the walls. The material is installed in such a way that it fits tightly enough to the insulation. A construction stapler is used for fastening. The joints are overlapped - 150-200 mm; the joints must be taped.

For such work, you can choose the simplest adhesive tape - there is no need to use construction material. Vapor barrier adhesive tape will also work.

To perform a vapor barrier, you can use foiled polyethylene, which will not thicken the wall thermal insulation (basic). Foam material is also often used for this task - this practice is common in our time.

Finishing the structure inside

Which is better: OSB sheathing or plasterboard cladding? Many are clearly inclined to favor option number one - when it comes to interior finishing work in the house. It is quite difficult to keep the frame posts in a completely level state - when work is being done, the same applies to drywall.

It’s just that the sheets of this material are softer when compared with osb boards. They will easily repeat all the irregularities - so then you will have to work hard to get perfect flat surface– more layers will need to be applied for leveling.

OSB board is an order of magnitude stiffer in structure than plasterboard sheets, so all flaws can be smoothed out to a certain extent. Afterwards they begin to carry out work related to finishing.

Watch a video about how OSB boards are used for interior decoration. This material will definitely be useful if you do not have much construction experience.

OSB-3 boards and roofing work

Roofing work is a very popular way to use materials such as OSB boards. By the way, to cover the roof with OSB-3 slabs, a material thickness of 0.18 cm is sufficient.

In order:

Products can have both a locking edge and a straight edge. The first option is more preferable;
Between load-bearing beams the distance should not be more than 609 mm - this applies to both the organization of sloping and flat roofs;
Are slabs capable of expanding? great importance. For each linear meter It is customary to leave a gap: 2 mm is quite enough (believe me, this is enough);
When laying slabs with smooth edges, the gap is made a little larger - 3 mm. Leave it around the perimeter of each slab - this is the only way to achieve optimal results;
Nails are used to attach OSB to the roof. Attached to supporting supports. There should be a distance between them: 10 cm or even more;
The finishing of OSB boards is attached with nails - they should have a length that exceeds the thickness of the board by two to two and a half times (or even more) - this is quite normal.

If the interior decoration is done using OSB panels, the following can be noted: a slab made of polished panels will look better if it is very important in your space appearance. It is better not to use such slabs for finishing. ceramic tiles or wallpaper - this is what the manufacturers themselves recommend. And it’s best to listen to their opinion!

Self finishing garage - all the most popular options

Each owner has his own idea of what his garage should look like. Simple enough for one metal box, and the second seeks to create a well-appointed and warm house, in which you can park your car, knock down a shelf if you need to, and meet with friends, a kind of mini-club based on your interests. Accordingly, the decoration of the garage inside and outside will be different. In this article I will try to highlight the most popular options for finishing garages today, with the emphasis on self-arrangement.

What does finishing work in garages include?

All structures of this type are divided into capital block and light metal constructions. Naturally, both materials and finishing technology will be different in each case.

But no matter which home you choose for your car, the overall technology includes four main areas:

The first and, perhaps, most important thing is the arrangement of the walls from the inside and, of course, from the outside;
The question of how to decorate the gate has always been considered a painful and no less problematic one.;
Whatever one may say, the car still has a decent weight and a durable floor in the garage plays an important role. Moreover, the problem doubles if the owner also wants to equip himself with a cellar or inspection hole;
Ceiling decoration can be called more desirable than mandatory, but we will also touch on this issue.

Since the finishing of the floor, ceiling and gate in all garages is generally similar, I will talk about these areas below in separate chapters. Let's start our conversation with options wall decoration in block and metal garages.

How and how to decorate walls in block structures

IN in this case Block structures mean buildings made of brick, cinder block, foam or aerated concrete, as well as solid or prefabricated reinforced concrete structures.

Of all the above materials used for the construction of garages, foam and aerated concrete require a special approach. It is strictly forbidden to leave these materials unfinished, since they are hygroscopic, that is, they can be quite saturated with moisture.

Good old plaster

As long as capital construction has existed, people have been plastering buildings. Therefore, the list of how to decorate the walls of a block garage is traditionally topped by plaster.

Many people strive to create comfort and make the finish pleasing to the eye not only in residential premises, but also in technical ones, for example, in the garage. In addition, sometimes such design is simply necessary, in cases where insulation or other material is hidden under a layer of finishing. Since you still want to save a little money, the inside of the garage walls is often covered with OSB board - an inexpensive and very well-proven material.

What is such a plate?

Oriented particle board, as its name suggests, is a similarity to the familiar chipboard - a material obtained by gluing shavings together. At the same time, the second part of the name – “oriented”, indicates that the chips in the thickness of the material are not randomly located, but in certain directions. Since the plate is multilayer, the chips are located in the inner layers in the transverse direction relative to the long side of the part, and in the outer layers - longitudinally. All types of smallpox can be divided into several groups:

OSB of the first type does not have moisture-resistant impregnation and coating. Not suitable for finishing and used for making furniture.
OSB of the second type is also not moisture resistant, but has greater strength than the first type.
The third option is OSB with a moisture-resistant coating and impregnation. It is best suited for indoor and outdoor use.
OSB of the fourth type is not so common and has maximum resistance to water, as well as mechanical strength. Mainly used for outdoor work.

To decorate a garage space, it is better to choose the third type of panels. They are able to withstand moisture and do not absorb it. Besides mechanical strength sheets are very high, which is quite important in this room.

How finishing is done

In principle, finishing garage walls with OSB slabs is carried out using exactly the same technology as decorating with plasterboard or other types of panels. You will need to assemble a sheathing or frame to which the sheets will be attached. However, here it is worth paying attention to the fact that a frame in a garage space is still preferable - it will allow you to put insulation into the wall and improve the situation with heat conservation.

There is only one nuance that sometimes prevents the assembly of a full-fledged frame - the small dimensions of the room. If the size of your garage is small, sheathing will be a more preferable choice, since it “eats up” a lot less space. The principles of assembling the frame and sheathing are no different from installing exactly the same structures under sheets of plasterboard or decorating with plastic panels.

Things to consider

To make your garage look beautiful and the finish to last a long time, you must follow some rules when installing all components, as well as subsequent decorative finishing.

If the height of the sheet is not enough to cover the entire space from floor to ceiling, it is necessary to follow the principle used when attaching drywall - install the sheets “in a staggered manner”, without creating cross-shaped joints.
It is necessary to leave a small compensation gap of three to four millimeters between the adjacent sheet and the sheets. It will allow the panels to deform slightly from humidity and change temperature conditions without allowing the sheet to warp. The gap is filled with sealant during finishing.
If the garage is humid, it would be a good idea to cover all surfaces with clear or tinted varnish. However, it cannot simply be applied directly to an unprepared surface. First, you should go over all the walls with medium-sized sandpaper, prime them, and only after that apply varnish. This treatment will significantly improve the ability of pockmarks to withstand exposure to water and increase the service life of the surface.

The rest will be easy. Having mounted in a standard way sheathing or frame, you attach the pox to them with long self-tapping screws. The screw heads need to be recessed into the plane by a couple of millimeters so that they do not interfere with further finishing, and all joints between adjacent parts are filled with acrylic sealant. It is better suited than silicone, since after installation the slabs are often painted, and the paint adheres better to the acrylic composition. The only difficulty that you may encounter is that the sheets are large in size and weigh a lot, therefore, it is better to call an assistant for finishing work.

Create indoors comfortable conditions and the cladding will make it warm and cozy garage OSB slabs. This modern finishing material is suitable for cladding walls and ceilings and has many advantages over conventional plywood or lining.

OSB boards are panels made from wood shavings. It is a building material consisting of wood shavings(thin chips), glued together with various resins with the addition of synthetic wax and boric acid. Sawdust from coniferous and other species is laid in them in several longitudinal and transverse layers, impregnated with paraffin and various synthetic resins. To give strength and durability, the material is pressed under pressure at high temperatures.

The resulting slabs are durable and free of cracks, chips and other defects. Covering walls with this material has many advantages:

such slabs do not delaminate;
thanks to antiseptic impregnation, fungi and mold do not appear on them;
the panels are flexible and easy to install on uneven surfaces;
the cladding is not destroyed by moisture.

How big is the quantity synthetic resin, the product labeling will tell you. The largest number of these components have slabs of classes E2 and E3, and the smallest are panels with the E0 and E1 symbol. Since the garage is not a residential space, it can be finished with OSB with any marking.

Installation stages

To sheathe a garage with OSB panels, you will need a frame made of metal or wooden beams. If the choice is made in favor of wood, it must first be treated with fire retardant impregnation and solutions against mold and mildew.

First, markings are made inside the garage. For curved walls, to draw marking lines, you need to select the most protruding section and use it as a reference point.

According to the markings, install horizontal beams, fixing them with dowels or self-tapping screws. Then, using metal corners, they are attached to the horizontal guides. vertical racks. Frame installation is complete.

Now all that remains is to finish the racks with OSB panels. They are attached to the frame with self-tapping screws, the length of which should be 4-5 cm greater than the thickness of the sheet. During installation, a gap of about 3 mm must be left between the plates - this will avoid deformation of the panels due to humidity or temperature changes.

To further protect facing materials from aggressive influence external factors, they can be coated with woodworking varnish. First, the surface of the OSB board should be degreased and lightly sanded.

You can also make a prefabricated frame on which to sew OSB boards. But the principle is still the same.

A garage made of OSB boards is one of the new technologies for constructing this type of structure. The production of panels occurs by pressing wood-polymer chips at a certain temperature. Due to the polymer in the form of resins, the fibers are glued together, resulting in durable slabs. Let's look at the pros and cons of OSB boards for garage construction.

OSB boards for the garage: pros and cons of the material

The advantages of the panels include:

Low cost compared to the construction of reinforced concrete slabs or monolithic frame for garage;
There is no need to order additional special equipment, since the slabs are easy to install yourself due to their low weight;
High characteristics of moisture resistance and strength;
OSB panels are easily amenable to any construction operations such as grinding, sawing and drilling.

The disadvantages of the designs include:

OSB boards are one of the options for sandwich panels, the middle layer of insulation in which quickly rots under large temperature changes;
Additional wind, hydro and vapor barrier is required, since if moisture gets on the insulation the insulation will be damaged. thermal insulation characteristics frame;
Since so-called “cold bridges” can form at the joints of sheets, you will need to seal the seams using shaped overlays;

A garage made from OSB slabs can be erected in literally 2-3 weeks. The cost of building a 3x6 garage box will be within 70 thousand rubles (the price is indicated taking into account all the installation and construction of the frame with your own hands). Let's look at the stages of construction and covering a garage with OSB panels.

Do-it-yourself foundation and subfloor for a garage made of OSB

A garage made of OSB panels should be installed on a strip concrete base. The width of the trench can be dug no more than 60 cm, and the depth is around 40 cm. This is due to the fact that such wooden garage It is quite light and does not require a massive foundation. A trench must be dug along the perimeter according to the selected size of the garage box, adding 100-200 mm.

After compacting the trench with sand, be sure to reinforce the entire area of the future foundation and fill concrete mixture. After 2-3 weeks, the concrete will set and the subfloor can be laid.

The floor can be made using timber and unedged boards. The most important thing is to lay it perfectly horizontally - use a level for this. The board is laid with small seams of 5-7 mm for natural ventilation floor. If you are planning to make a warm garage for use in winter time years, then lay the boards tightly and additionally insulate with 30-40 mm polystyrene foam.

Having completed all the work on tying the subfloor to the foundation, you can proceed to the second stage: erecting a frame of OSB panels on the tape.

Installation of garage frame and roof from OSB panels

First, we install vertical racks made of timber, with a section of 150x150 mm. You can also build a frame from metal profile. But then additional painting and processing is necessary. special solution from rust. The stands are attached using iron corners on the bolts. Next, we drill holes for the horizontal beam in the middle and fasten it with bolts. All that remains is to fill the resulting openings under the wall opening with OSB boards.

Important! Be sure to leave an opening on the end side for the gate. In addition, you need to cut holes on the side of the garage for plastic windows And entrance doors. The dimensions of technological holes can be seen in the projects.

WITH outside Insulation boards of 20-40 mm in 1-2 layers are attached to the sandwich panels. It all depends on what region you are in and whether you intend to use the garage in winter. For exterior finishing you can use PVC panels or simply paint the walls in the chosen color. The inside of the garage is mainly lined with clapboards and the OSB boards are left unfinished.

Attention! Since OSB is easily destroyed under the influence of moisture, a film for hydro and vapor barrier must be laid under the contour of the panels. This will help keep the OSB garage dry and warm for many years.

Making your own garage roof from OSB panels is quite simple using hollow-core slabs. They are relatively light in weight, so lifting them yourself without the help of specialists is quite easy. In this case, the wall frame will not be subject to serious load. After laying the floor slabs, it is necessary to lay out the logs and install rafter system roofs. Then the sheathing is made from the planed board, the gables are sewn up and laid roofing material. The process of erecting a roof on a garage is described in more detail in the corresponding section on the website.

conclusions

Provided that a garage is built from OSB boards in a dry climate, such a building without reconstruction and finishing can last about 30 years. In cold climates with high temperature variations garage box will last 10-15 years.
