What is the difference between glued laminated timber and ordinary timber? Glued and profiled timber: which is better to use in construction.

What is the difference between lumber like board and timber? What lumber is widely used in the construction of log houses? You can read the answers to these questions in our short note.

What is the difference between timber and board?

Let's start with what a bar is. Beam - wood material, made from logs by cutting off their sides (edging). Depending on the number of the latter, there are 2, 3 and 4-sided timber. The exception is the so-called, which is made by connecting several lamella boards. Boards are made from logs or beams, depending on the processing, they can be edged or unedged.

In general, to the question “What is the difference between a beam and a board?” it is not so easy to give a definite answer. The point is not only in the size of the lumber, but also in the purpose for which it will be used. Most often, timber is used as a material for the construction of enclosing or load-bearing structures. It can be the walls of a house made of timber, a roof, a skeleton frame building. In turn, the main purpose of the boards is finishing work.

Judging by the dimensions of the lumber, the ratio of thickness to width of less than 1/2 means that we have a board in front of us (with a thickness of up to 100 mm). If this ratio is greater than or equal to 1/2, we have a bar in front of us. However, in the latter case, a bar and a bar are also distinguished. If, with the above ratio of parameters, the thickness or width is less than 100 mm, then this is a bar. Everything else is called bars. For example, 100x200, 150x150, etc.

Lumber used in the construction of houses

Depending on the goals pursued and wood processing technologies, a whole range of lumber is distinguished. Each product is used for its intended purpose. So, timber is most often used for load-bearing structures. Boards are used for finishing works, both indoors and outdoors. Below we have presented a small table with the main range of lumber used in the construction of timber houses.

Building materials made of wood differ not only in their size, production technology, but also in characteristics that allow them to be used in various areas of construction. In search of differences between timber and boards, they are first set by the intended use of these materials, and only then they talk about their geometric dimensions.

Variety of lumber coming to construction markets, very large. And if everyone understands what a board is, then with some other terms it’s not so simple. Who can immediately answer what is the difference between a bar and a bar? Unless you're a builder, a carpenter, or a sawmill worker, you probably don't know the difference between the two. But it's actually very easy to figure it out.

Beam or bar

The suffix "ok" in Russian is a diminutive. In other words, when it is added to a word, the derivative will mean something less than the thing called the original term. The way it is. According to GOST, lumber is considered to be lumber with a thickness and width of 100 mm or more. If at least one parameter is less than 100 mm, this is no longer a beam.

A bar is lumber with a thickness of less than 100 mm, and the ratio of width to thickness should be no more than 2 to 1. If the ratio is greater, then it will no longer be a bar, but a board. Of course, with the boundary values ​​​​of thickness and width, the difference between a bar and a bar is conditional, because when planing with a planer, it is easy to remove a few millimeters of material, formally transferring it to another “category”. Since the main difference between these lumber is the thickness, the scope of their application will also be different.

The standard types of bars used in our country in terms of thickness and width for different breeds trees are presented in the following table:

Comparison

Timber as massive and durable lumber is mainly used in construction to create load-bearing structures. It is usually used as beams or supports, occasionally - in the construction of walls, followed by siding or other cladding. Bar like less durable material found its “vocation” in construction during the construction of not so powerful structures - for example, it is used as lags when laying a plank floor, as well as in some other cases. Outside of construction, the bar is used in the production of containers and in the furniture industry.

If a bar is obtained by sawing a bar or boards, then the bar can be made both from logs and by gluing boards. Both materials are planed if necessary. Any number of sides can be planed. If two opposite sides are processed, such a beam is called two-edged, if three - three-edged, four - four-edged.

Both timber and bar are calibrated. Calibration consists in drying lumber and processing it according to specified dimensions or patterns (calibrated profiled timber). Preliminary drying is necessary so that the bar or bar subsequently does not “lead” during the natural evaporation of moisture, which will necessarily affect its size and shape. Calibrated profiled timber, made from some tree species, is used to build houses. Such walls are treated from the outside with a special composition and basically do not need exterior finish. A profiled bar is most often used in furniture production. On this, perhaps, it is possible to complete the story about the difference between a bar and a bar.

What is the difference between glued laminated timber and ordinary timber?

Beautiful, environmentally friendly, easy to build and relatively inexpensive buildings can be seen both in elite villages and within the boundaries of large cities in all regions. To priority benefits wooden houses, can be attributed to:

• Regular air exchange through the array providing ventilation.
• Unparalleled sustainability.
• The property of a tree to release phytoncides that disinfect the air.
• aesthetic appearance.
• Low thermal conductivity, allowing you to save on heating.
• Manufacturability of the material, which simplifies the construction process.
• Availability of processing and decoration.
• Investment attractiveness of the project as a whole.

Despite the commonality of the main characteristics of wood materials, before starting construction, it is necessary to answer the question: “Which timber to choose?”. Most modern developers prefer glued beams, which are distinguished by durability, reliability, affordability and an adequate pricing policy.

Comparative analysis of glued beams with other types

To get an objective assessment of glued laminated timber, we will conduct a small comparative analysis of this material and, say, solid timber.

First, let's define the concepts:

• Glued laminated timber is a building material, the characteristics of which meet all the requirements for individual construction. The technology of its manufacture allows you to fully preserve all the properties natural wood. External difference house built from glued laminated timber log cabin, consists in smooth and flat surfaces.
• Solid timber is a building material that is obtained as a result of four-sided edging of logs. It is widely used for low-cost construction country houses and outbuildings. The manufacturing technology of the material is considered the simplest and least expensive. Developers warn that after the end construction works, the house shrinks significantly and for a long time due to the high natural humidity.

From what material will be chosen for construction wooden house, depends on the timing and cost of construction work. It is worth noting that, despite the fact that glued beams are somewhat more expensive than solid ones, in the end, the total cost of construction and further operation will not differ significantly.

Competitive differences of glued beams

Spruce and pine are most often used in the production of glued beams. Depending on the destinations of the future, the thickness of the walls is chosen at home. So, for example, for capital housing, the best option will be 220mm, and for seasonal - 150mm.

Based on these initial requirements, the material is selected and calculated. The main advantage at this stage can be considered standard sizes blanks, which significantly reduces costs and installation time.

The remaining advantages of glued beams can be structured as follows:

• The technology used in the production of glued laminated timber provides for thorough forced drying of all lumber, providing high strength, resistance to moisture and ultraviolet radiation.
• In the process of manufacturing glued beams, the slats are glued together with a special glue that does not emit toxic substances during the construction and operation of the building.
• Glued laminated timber has a perfectly smooth surface that does not require expensive decoration methods.
• The aesthetic component is no different from other types wooden material, because the natural color of the tree and naturalness are preserved.
• Glulam technology ensures a minimum percentage of deformation even when long-term operation houses in the most adverse climatic conditions. The structure will not shrink or crack.
• Resistance to mechanical damage.
• In the manufacture of glued laminated timber, protective antiseptic impregnations are used, which prevent the appearance of mold, fungi and repel moisture.

Thus, glued laminated timber has a number of advantages that make it a popular material for houses for various purposes.

Internal and external processing of timber houses

The final stage in the construction of a wooden house is its internal and external processing. It should be noted that this procedure is mandatory for both solid and glued beams. However, in this plane there are significant differences that speak in favor of glued beams.

Wood is natural material subject to destruction due to the appearance of mold, fungus or decay. Processing with special materials and decoration help to significantly extend its service life.

It is worth noting that houses built from glued laminated timber are less vulnerable to both the above factors and moisture, since already at the first stages of production, the slats from which the timber is made undergo special processing. If the house was built from a single bar, the owners will have to repeat the application procedure several times protective equipment- after completion of work, and then after the expiration of the shrinkage period.

Interior decoration of the house from glued laminated timber

Separately, it is worth noting the features of the interior decoration of wooden houses made of solid and glued beams. The owners of a house made of solid timber are waiting for a wide range of work, which involves leveling surfaces, grinding, priming, painting or varnishing. After some time, the process of deformation of the structure will begin, which can lead to cracking or other types of damage.

Houses made of glued beams do not need expensive interior decoration. Perfectly smooth surface allows to realize interesting design solutions based on emphasizing naturalness and environmental friendliness. In most cases, the walls are simply covered with a colorless varnish, which allows the color and texture of the wood to be preserved.

As a conclusion, we can state the expediency of using glued laminated timber, in view of its undeniable advantages before the rest building materials this category. At the same time, it should be noted that for budget construction it is better to use other, cheaper types of timber.

Lumber used in the construction of houses

Depending on the goals pursued and wood processing technologies, a whole range of lumber is distinguished. Each product is used for its intended purpose. So, timber is most often used for load-bearing structures. Boards are also used for finishing work, both indoors and outdoors. Below we have presented a small table with the main range of lumber used in the construction of timber houses.

Building materials made of wood differ not only in their size, production technology, but also in characteristics that allow them to be used in various areas of construction. In search of differences between timber and boards, they are first set by the intended use of these materials, and only then they talk about their geometric dimensions.

Construction timber houses is becoming more and more in demand. The material is ecologically impeccable, allows you to get an optimal microclimate for a person indoors, is characterized by low thermal conductivity, reliability and wear resistance. For the construction of cottages, profiled or glued beams are used, each of which has certain advantages.

Features of profiled timber

Profiled timber most often has natural humidity and after construction shrinks, the duration of which can exceed 12 months. Delivery of the dried material having humidity no more than 20% is possible. Such a beam is more expensive, but the shrinkage of the material is minimal.

Due to the processing of solid logs, during which the hardest part is cut off from the logs, the strength of the profiled timber is lower than that of the glued one. The advantages of the material include:

• Ecological cleanliness, the absence of foreign impurities in the timber.
• Profiled timber has an attractive appearance and texture, does not require additional processing and finishing after installation.
• Subject to compliance technological process when laying crowns, the thermal conductivity of the material is minimal, which has a positive effect on heating costs.
• The cost of profiled timber is significantly lower than that of glued timber.

When choosing a profiled material, the owner suburban area can save a lot. In this case, the operation of the house can only be started after the final shrinkage of the building.

Features of glued laminated timber

Glued laminated timber is made by gluing lamellas special formulations, environmentally friendly and does not emit harmful elements. This manufacturing technology guarantees high strength of the material, resistance to deformation, a minimum number of cracks and crevices. For production, the most dried wood is used, due to which shrinkage finished house does not exceed 1%.

During operation, the cottage gradually absorbs water, and the moisture content of the material approaches the same characteristics of profiled timber. Unlike other materials, glued beams:

• unaffected by harmful micro-organisms
• does not rot
• has a large operational resource.

The main disadvantage of the material is its high cost.

How to choose a timber for building a house?

Both variants of timber are suitable for private construction of both houses and cottages, as well as suburban buildings. Modern technologies production of materials allow us to achieve excellent quality from profiled and glued beams and the same performance characteristics. When choosing, compare following options timber:

• If you need to reduce the cost of construction, it is best to choose profiled material.
• For erection big houses and cottages, glued timber with a width of up to 0.275 meters is best suited, while its profiled timber has a maximum width of up to 0.2 meters.
• If environmental friendliness is considered to be the determining parameter, it is allowed to use profiled material or glued material made using appropriate compositions.
• Air exchange is significantly better in material made from solid logs.
• If we compare the duration of the shrinkage process, then glued laminated timber wins.

From an aesthetic point of view, both materials make it possible to obtain externally attractive and stylish houses that can please their owners for 50 years, subject to the rules of operation. Durability log house not inferior to buildings made of other materials.
