For the construction of various structures from time immemorial, people have used wood. And although during this time there has been a significant evolution of construction technology, many wood products have remained unchanged to this day. This primarily applies to such unsurpassed lumber in popularity, such as boards and beams. It will be interesting to find out what are their differences, as well as which of these materials is stronger.
The main differences
Lumber is the name given to products from the processing of wood material, which is formed when logs are cut with the help of special equipment. Depending on the method of sawing the lumber, you can get boards or bars . The latter are used both for the construction of load-bearing structures and for interior decoration of premises. Some consumers often mistake edged building boards for timber, but there is a difference between these wood products.
A bar is considered a high-strength building material used in critical (load-bearing) parts of wooden buildings being erected . It is often used for supporting functions during frame housing construction, as various kinds of beams, floors, rafters and floor logs. Counter-laths are often arranged with a bar in the roofing business, since it differs significantly from the board in strength. The latter does not have such a high bearing capacity as a timber, therefore it is mainly used for finishing the floor, walls, ceiling, as well as when forming the lathing. In addition, the board is ideal for the construction of summer gazebos and light outbuildings (for example, sheds).
As for the dimensions, the board is called lumber, the thickness of which cannot exceed 100 mm. But at the same time, the width of the product should exceed the thickness by 2 times or more. In the case of a bar, the width is either equal to the thickness, or slightly more (up to 2 times).
It should be borne in mind that a full-fledged bar can be called a product that has a thickness of at least 100 mm. Lumber that resembles a bar, but with side sizes less than this indicator, experts call bars, from which lighter wooden structures are constructed. And very thin square products with side dimensions less than 50 mm, rather, can be attributed to slats that are not related to the main elements of the building.
Depending on the processing of the sides, the timber is divided into the following types:
- two-edged (that is, having 2 processed opposite sides);
- three-edged (with 3 processed sides);
- four-edged (all available sides are processed).
As you can see, the main difference in the materials is their intended use. All others (dimensions, geometric shape, processing method) are already considered after the definition of the function of the building material. It must also be said that the boards are made either from logs or from a bar. A board with a thickness of 100 mm also consists, in fact, of at least two elements of a bar, for example, with dimensions of 100x100 mm, not to mention the number of bars that can be made from it.
Can a board be used instead of a bar?
Depending on the purpose and technology of wood production, the type of sawn timber is determined, which is best suited in a particular case. Each product must be used strictly for its intended purpose. This rule applies to beams and planks. The timber can be used as an alternative to the board for interior and exterior decoration of the room . But it is not recommended to use an edged board instead of a timber, since it is less reliable.
In the event of such a replacement, the life of the structure is likely to be significantly reduced.
What's better?
Many people often think about what kind of tree is best used for building and covering a house. The issue can be resolved only after considering the quality characteristics of the materials, as well as clarifying the external design of the building. The timber is stronger and more reliable than edged boards, but it also costs much more . In addition, using a timber, the consumer does not have to insulate the walls from it from the inside, protect them from mold and even trim.
Unfortunately, It will not be possible to give an unequivocal answer for a better choice between a bar and a board, since the material must be purchased depending on the tasks that are assigned to it . The beam is stronger and more reliable, so it is ideal for organizing the frame and support. In turn, the board is a building material with good performance characteristics, thanks to which it can be used to decorate the interior of the structure.
- To the benefits timber include strength, environmental friendliness, ease of installation. The disadvantages are the complexity of manufacturing, high cost.
- Pluses edged boards are considered: ease of processing and installation, environmental safety, attractive appearance. The disadvantages of the product can be called a tendency to rot, the appearance of mold, as well as fragility in case of improper use.
