The woodworking plant "Kalevala" is one of the largest enterprises for the production of OSB-boards in all of Russia . The plant has the most modern and high-tech equipment. Therefore, their products are environmentally friendly and meet all international quality standards. The plant is located in the Republic of Karelia, in Petrozavodsk.

Advantages and disadvantages

OS board "Kalevala" is an oriented strand board produced by a relatively young company founded in 2013 . German equipment is installed there and the most innovative technologies are applied.

Manufacturers use pine, spruce, and larch as the main material.

Initially, they are cleaned of branches and bark, and then crushed into flat chips from 0.4 to 0.8 millimeters thick, 2.5 to 14 centimeters wide and 0.5 to 5 centimeters long. OSB-boards include:

• about 90 percent wood;
• urea-melamine resins;
• resin of coniferous trees;
• isocyanic resins;
• paraffin emulsion.

Such components make the slabs moisture resistant and environmentally friendly.

This material can be used in a variety of areas:

• in furniture production;
• in the construction of partitions;
• for filing the ceiling;
• as bases for roll roofs;
• for the assembly of billboards;
• to create pallets;
• for the construction of country houses.

OSB "Kalevala" have many advantages

1. First of all, it is strength. They can even be used to create those structures that are subject to heavy loads.
2. Compared to wood, OSB boards are lighter and more moisture resistant, they practically do not rot, they have no knots or small cracks.
3. The material has good noise and sound insulation.
4. Since the boards have a smooth and even surface, there are no problems when laying the insulation.
5. Plates are durable. They retain their attractive appearance over time.
6. OSB boards are very lightweight.

Despite the large number of advantages, it is worth noting some of the disadvantages of this material

1. First of all, it is an unpleasant smell coming from OSB boards. This is easily explained by the fact that phenolic resins and boric acid are used in the manufacture. An unpleasant odor is especially noticeable when wall cladding indoors. However, a few days after the end of the work, he disappears.
2. Another drawback to which you need to pay attention is too low vapor permeability. If you use OSB plates both for wall cladding and for finishing the floor, then it will be very difficult for fresh air to freely enter such a room.
3. This material is susceptible to fungal infections. Manufacturers are trying to solve this problem by treating the surface of the plates with special antiseptics.
4. At the folds, the slabs can easily deform, so you need to be very careful when working with them.

Types and their characteristics

Oriented strand boards are divided into several types.

OSB-1

This type of board can only be used in places with low humidity. It is suitable for the manufacture of furniture, packaging, as well as for wall decoration in moisture-resistant rooms.

OSB-2

Such plates are more rigid. They are not suitable for external cladding, but can be used in dry rooms and when laying sub-floors.

OSB-3

Plates of this class are distinguished by higher strength. In addition, they are already moisture resistant. They can be used as flooring or to create load-bearing structures.

OSB-4

This type of slab is considered the most durable and reliable. They can be used both indoors and outdoors, without worrying about the fact that the material is deformed.

The disadvantage of this material is the high price.

OSB is also distinguished by the method of finishing the sheets

1. Unpolished … Most often, such slabs are used as roof decking. They have a rough surface for high adhesion.
2. Sanded … Such sheets are machined. They look beautiful and are suitable for wall cladding.

Most of the OSB boards have standard parameters. The weight of a sheet with dimensions of 12 mm by 24 mm is 12, 5 kilograms. Moreover, its thickness is 0.6 cm. Slabs measuring 1250x2500 weigh about 18.3 kilograms. Each sheet is 9 mm thick.

Comparison with OSB of other brands

Nowadays, a large number of manufacturers have appeared on the building materials market who are engaged in the manufacture of OSB . It is very difficult for an uninformed person to see the differences and understand what is the difference between the plates of different manufacturers.

Among other advantages, it is worth noting the homogeneous structure of the ends and the vapor permeability of the material. The disadvantages include the weak rigidity of the plates.
