OSB-3 plate: characteristics and application

OSB-3, whose characteristics are of interest to many domestic craftsmen, has recently gained great popularity. The field of application of these canvases is very wide, including the OSB is often used in the arrangement of the base for mounting the roof linings and bituminous shingles.

Characteristics of OSB-3

OSB-3, the technical characteristics of which comply with safety standards, can be applied in the interior of living quarters. The class OSB-3 assumes the possibility of using the material for external and internal works. Humidity can be moderate, which distinguishes the canvases of this class from OSB-1 and OSB-2. The last two options have not so impressive density and do not undergo even a little increased humidity.

OSB-3 is based on wood chips. Cloths are produced by the method of pressing chips, when they undergo the action of high pressure and considerable temperature. A glutinous base here is a waterproof resin. Plates consist of several layers, chips in each of which are differently oriented. OSB-3 - a plate whose characteristics deserve attention - much stronger and more elastic than wood. The material is free from defects in the form of knots.

Application area

OSB-3, the characteristics of which are impressive, can be used in the construction of frame structures, as well as in the process of covering the frame of the framework of walls. Convenient canvases and when leveling floors, as well as overlapping. The builders found the OSP one more use: when constructing a structural system of stairs and staircases.

Floor leveling with OSB-3

OSB-3, the characteristics of which allow the material to become increasingly popular, can also be used for floor leveling. Their laying is performed on a pre-assembled lag system. In this case, between the webs at the time of the flooring there should be a temperature gap, the minimum width of which is 3 mm. Whereas between the slab and the wall, the width of this groove should be equivalent to 12 mm. The webs should be positioned, guiding the main axis at an angle of 90 ° with respect to the lags. The conjugation of short edges of the OSB should be located on the logs. Long edges that do not have an emphasis on the bars, must have a lock-groove, a bracket or some support.

If the material is stacked on logs installed on the ground, the soil must be well waterproofed. To fix the plates you should use self-tapping screws, which can be replaced with spiral 51 mm nails. Whereas if a ring fastener is used, its length should be 45-75 mm. Installation of fasteners is carried out with a step of 30 cm, with regard to the intermediate supports, on the fasteners is installed at a distance of 15 cm.

OSB-3 is a plate, the characteristics of which will determine whether it is worth buying - can be glued to the surface of the log, this will increase the rigidity of the system. Use at the same time is recommended mounting glue, made on the basis of chemical solvents. In the areas of the comb-groove locks, it is necessary to apply glue type D3.

Tools and materials

To perform work on leveling the floor or arranging the flooring, it is necessary to prepare some tools and materials, among them there are:

• Self-tapping screws;
• Plates;
• Lags;
• Waterproofing.

Installation of OSB-3 on walls

OSB-3, the characteristics of which allow you to install on all types of surfaces, can be used for wall leveling. Between the webs, as well as around the openings, you should leave a gap, the minimum width of which is 3 mm. When walls are walled, professionals are advised to use OSB, the thickness of which is 12 mm. If there is a need to make additional insulation of the system, you can buy mineral wool, and apply mineral plaster on top of the slabs.

Plywood OSB-3, the characteristics of which attract domestic craftsmen and professional builders, is attached to the wall using self-tapping screws or 51-mm nails. When installing the fasteners, do not approach the edge of the sheet more than 1 cm.

Mounting of the OSB on the roof

OSB-3 boards, the technical characteristics of which allow them to be used in outdoor work, should only be attached after checking the smoothness and strength of the rafter's feet or the lag of the lathing system. If the above elements are not installed smoothly, this will affect the appearance of the roof. When wetting the canvas in the rain, use them is not recommended until dry. When installing over an attic or any other space that is not heated in the winter, you should take care of ventilation. Holes for this should not be less than 1/150 of the entire horizontal base.

Considering the structure of the canvas, it is necessary to fasten it with a long edge at right angles to the rafter or elements of the crate. Pairing short edges of the sheet should be on the roof supports. As for the long edges, they also need to be secured or stapled, where necessary. Between the material with straight edges it is necessary to form a gap with a minimum width of 3 mm: this eliminates deformation during expansion. Plate should be at least two pillars.

Installation in the presence of a chimney

At the moment of fixing the material, the masters should remain on the rafters or elements of the crate. If the roof system has an opening for the chimney, then the lining must be moved away from the chimney to a distance approved by the building codes. In this case, it is also necessary to use self-tapping screws or nails. Install fasteners at a distance of 30 cm, placing self-tapping screws on rafters or components of the crate. As for the areas of coupling, the distance between the screws should be 15 cm.

OSP-3 2500h1250h9mm "Kalevala"

The OSB-3 plate 2500х1250х9mm "Kalevala", the characteristic of which will determine whether you should use it for your own needs, is a modern material. It is superior in its qualities to plywood and chipboard. At the heart of the blade are not only chips, but also technological resins. As a rule, OSB is made from aspen, as this breed is less exposed to the environment. The cost of the canvas is 550 rubles. When installing, it is worth counting on the fact that the weight of one sheet is 17.3 kg. It is easy enough to saw, cut, plan, and if necessary even grind.

Do not be afraid that the material will not retain the nails, in addition, among themselves, the slabs can be glued together with joinery, which will make it possible to get a sufficiently strong connection. If it is intended to use the material outside the premises, it is recommended to coat it with varnish.

By roofing OSB-3, you will get a system that has excellent heat and sound insulation properties, which is very important for private buildings in case of rain or excessive activity of birds. If you have a business in the production of upholstered furniture, then the material described will find its use in the construction of buildings.

A fairly wide scope of use has enabled OSP to gain popularity. This material gradually replaces the analogues, because its quality characteristics attract the attention of consumers.
