All About Kiln Boards

Currently, various wooden materials are widely used in construction and finishing work. They can be made from a wide variety of breeds and in a variety of ways. In this case, all the workpieces are preliminarily thoroughly dried. Today we will talk about kiln drying boards.

Kiln-dried boards are dry lumber, the moisture level of which becomes minimal during such processing.

Wooden blanks are sent for drying in special ovens, which ensure the most efficient and deep drying. It is not recommended to use naturally dried wood in construction, because after its installation, strong shrinkage will occur, the material will begin to deform, and then collapse, as a result, the structure may break.

Moreover, even after chamber drying, the wood will still contain a certain percentage of moisture.

Chamber drying takes place in several main stages.

• Material preparation. At this stage, the raw materials are sorted. All blanks, depending on the quality, are divided into separate groups.
• Warming up. To prevent a strong tension of the internal structure of the tree, it is warmed up a little in advance by short-term heat exposure.
• The main stage. Direct drying takes place in the chamber. In this case, the transition should be gradual, at this moment the most suitable parameters of heat flows are established.
• Moisture heat treatment. At this intermediate stage, the maximum removal of moisture from the wood is ensured, while one temperature regime is stably maintained. Sometimes installations with fans and extractors are used to regulate the process.
• The final stage. At the end of the chamber drying, regulation and final leveling of the moisture values ​​of the wooden boards takes place. Too dry elements are slightly moistened, and poorly dried lumber is sent to dry out. In terms of time, chamber processing takes several hours. The period in this case will depend on the volume of the laid material and the size of the boards.

These lumber can be very different depending on the species from which they are produced. Most often, various types of wood are used for their manufacture.

It is this material that is mainly used to create boards.

This breed has an unusual and beautiful natural structure, so it is often used for finishing work. And also dried pine structures allow to provide good thermal insulation. The material lends itself easily even to deep processing. This breed dries quickly.Pine has a low cost, and its processing does not require large costs.

This breed also lends itself well to any processing and drying. Larch has an increased stiffness, it is considered a fairly resistant, durable, strong wood. And also the tree boasts a variety of colors and textures.

Larch contains special phytoncides, due to which it has important antioxidant properties that protect humans from pathogenic bacteria and various viruses.

This breed is as strong and durable as possible. Oak materials lend themselves well to chamber drying and deep processing. They can withstand high levels of humidity, heavy loads.

The wood has a pleasant light brown or yellow color, but over time it begins to darken gradually, sometimes acquiring a red tint.

The tree will be able to withstand high humidity, heavy loads. But at the same time, it is significantly inferior in terms of strength to other types of wood. Birch has a homogeneous wood, it is a nuclear-free variety, has a pleasant light brown tint.

The breed also has a homogeneous structure. After kiln drying, linden wood has a significant density. It is distinguished by its light, beautiful colors. But at the same time, linden cannot be called a durable material - it does not tolerate moisture well. If it is not dry enough, it will quickly crack and deform. In addition, birch does not have high strength either, therefore it can be suitable for the manufacture of only lighter or temporary structures.

This wood has a beautiful color and interesting texture, therefore, it is maple that is often used for finishing structures.

All wooden planks can also be divided into two large groups, depending on the manufacturing technology.

• Cut type. Such boards are thoroughly processed and dried. They have a rectangular cross-section. They are not characterized by edges with bark particles. This lumber is formed from a log using a longitudinal cut. It is this variety that is most often used in the process of installation work, exterior and interior decoration. Edged boards are mainly made from softwood.
• Unedged variety. Such models are used a little less often. They are also made by ripping, but the barked edges will not be cut. Unedged boards are not used for decoration, they do not have an attractive appearance. Such a tree is used to form various flooring, roofing battens, individual parts of load-bearing structures.

Besides, it is worth highlighting the dry planed variety of boards. Such lumber is versatile. It goes through deep chamber drying and processing from all sides using specialized powerful equipment.

The calibrated material can be called multifunctional, since it can be used in a wide variety of areas., including for the design of facades, the construction of fences and partitions, the installation of floor coverings. All the positive properties characteristic of this type of boards do not change after drying in the office.

Before buying such lumber, be sure to pay attention to their size. Models with values ​​of 150x50x6000, 200x50x6000, 50x200x6000, 50x150x6000 millimeters are considered standard, but there are samples with other sizes.

Kiln-dried boards are widely used in construction and finishing works.

So, they are often used in the creation of residential buildings, the design of floor coverings, internal partitions, as well as fences, ceilings, terraces, verandas, facades.

Some varieties, made from beautiful wood species with original colors (maple, birch, linden), are used to create various decorative products. The natural pattern of this wood can also make them more interesting.
