Natural wood has been and remains one of the most popular building materials due to its environmental friendliness, strength and aesthetics of appearance. Wood has negative properties that must be taken into account during construction. Let's take a closer look at the timber of natural humidity, the advantages and disadvantages of the material, because its use provides for a special technology for creating wooden buildings.

What it is?

Profiled timber of natural moisture is used for the construction of private houses and country buildings. Such material externally looks like a square or rectangular solid wood board and assumes 18-20% wood moisture, that is, the timber does not pass drying, in contrast to the dry version . According to the standard, the building material must be smooth and even, this applies to its front surfaces, which excludes additional finishing work.

However, immediately after the rough work, it is impossible to proceed to finishing - due to the water content.

Its quantity is influenced by the environment - wood is highly absorbent . But the timber retains its percentage of moisture only for a certain period of time and subsequently loses this property during operation, especially if the house is often heated. For the construction of a wooden house, such a beam is usually used with a limited budget, since it is more than affordable in cost compared to similar materials. In its category, winter wood is valued higher, but the species of wood, the type of profile and its section also affect the price.

Pros and cons

Wet construction timber has certain advantages for building a house

• It is more affordable and cheaper than rounded logs and timber glued from boards.
• Ideal for the construction of summer cottages, since it is considered more reliable than frame-panel construction.
• The disinfecting properties of coniferous timber are well known; moreover, it is cool in a log house in the hot season.
• The building material has other useful properties - despite the shrinkage, the installation is quite simple, and it can be dealt with without the intervention of professionals. Even without cladding, the material looks beautiful and aesthetically pleasing.

But in housing construction, it is advisable to know about the shortcomings of a wet bar

• The consequences of an increased amount of moisture are the appearance of fungal organisms - mold spots and bacteria that cause rotting of the material. If the wood is not ventilated, it will quickly deteriorate, rot and lose its presentation. To avoid this trouble, it is important to think over the ventilation system to the smallest detail.
• From 6 months to a year, the structure shrinks, amounting to about 5%. Because of this, living in the house (without finishing) is impossible.
• A significant disadvantage of a wet bar is that it dries, and this can significantly affect the shape and size of the building material - its width and thickness are reduced. Shrinkage leads to cracking of the tree, and the owner will have to think about the use of screeds in the form of special pins and nails at the beginning of construction. Another problem, if the timber has become dry, is twisting due to stress stretching the tree in three directions.

Based on the shortcomings, it is easy to come to the conclusion that it is better to use dry chamber drying building material.

Application

A suburban building can be erected from a simple bar with minimal processing. Such profiles do not have fasteners and are usually used for the construction of ceiling beams, log floor or are used for pile-screw foundations as a strapping.

It is also used for the construction of walls, but this requires the cost of facing and grinding the surfaces of the timber, which differ in some roughness . Therefore, it is advisable to take a profiled type of material of natural moisture for the construction of residential premises. In addition to the fact that the front sides of the profiles are smooth, they are equipped with special spikes and grooves.

The peculiarity of using wet wood is assembly for shrinkage . Since this natural process can be interfered with by additional structures, for example, doors and windows, they are not installed immediately. The roof does not interfere with this, so it can be installed, but it is important to provide ventilation for the walls to prevent the development of fungus and mold. At the same time, it should be remembered that the walls are mounted only with the use of wooden dowels, since metal clamps rust and contribute to the appearance of cold bridges.

Professional builders recommend building a house from wet material in the winter.

How to treat with an antiseptic?

Disinfecting treatment is carried out with the onset of stable, warm weather, when the air temperature does not drop below + 10-12 degrees at night. Antiseptic agents such as "Neomid-440", "Fenilaks", "Biosept" are designed to prevent the aging process of the tree and its rotting , retain the beauty and structure of the material. Some compounds, for example, "Senezh", additionally bleach wood.

Raw wood processing includes several stages

• First, the surface is prepared - cleaned of dirt and dust, polished.
• First of all, the composition is applied to the corners, the ends of the timber.
• The antiseptic can be applied with a roller or brush, at least two layers thick, at intervals of several hours.

Internal and external processing will protect the house from a wet bar for 15-20 years, but this depends on the thoroughness of the work done.
