Profiled timber of natural moisture: features of use in

Natural moisture profiled timber is a building material that many experts choose because of its relatively low cost. However, in this regard, the builders do not show unanimity, because some believe excessive humidity is critical for the performance of the timber. Is this true, and how can you deal with such phenomena - we will tell in our article.

Technological aspects of production

How do profiled timber

Discussions about what is better - timber or timber, as well as which timber is better - dry or natural moisture - among professional builders does not lose its relevance to this day.

In order for our readers to form their point of view, first we will figure out what the construction beam itself is:

• Most often, timber means a blank that is either cut from a solid wood trunk or glued from boards of suitable length and thickness.
• On the upper and lower planes of the beam, a special shape profile is formed during the manufacturing process (the “two spikes” and “comb” configurations are the most popular). The profile configuration is chosen so that the two beams are interconnected with almost no gap.

• The most simple to manufacture is considered a massive material, cut from a single piece. Glued varieties of timber, for example, from larch, are distinguished by a high price, but at the same time they are characterized by minimal shrinkage and almost complete absence of deformations.

As for the moisture content in wood, according to this parameter, raw materials of natural moisture content and billet, subjected to chamber drying, are distinguished. What is a bar of natural moisture and what is its difference from dried, we will tell in the next section.

Moisture

Wood moisture is an indicator that characterizes the proportion of water in the composition of building materials.

And here you should take into account a number of nuances:

• The water in the tree is divided into two categories - free and bound. Free moisture is removed from the wood very easily by natural evaporation. It is enough that the wood has lain for some time in a room with a normal level of humidity - and the proportion of free water in the timber will be reduced to a minimum.
• With bound water, it is becoming more and more difficult: special technologies have to be applied to remove it, since natural drying demonstrates very low efficiency. In addition, an increase in the amount of bound water leads to a decrease in the strength of the wood.

Proceeding from this, under the bar of natural humidity understand the material that has been subjected to the removal of only free water. To reduce the content of bound moisture, it is necessary to treat the wood in special chambers - this is the only way we can get a dry timber.

Features of use in construction

What is the difference between houses from natural moisture bar from buildings erected from dry material?

• The first and most important difference is the shrinkage of wood. The fact is that the associated moisture, as we noted above, leaves the wood slowly. When this occurs, the deformation of the wooden parts, causing a change in linear dimensions.

Note! A house from a bar of natural moisture during the shrinking process is deformed unevenly: the change in dimensions in the transverse direction is much greater than the compression along the fibers. Simply put, the house becomes lower, and the width is compressed slightly.

• If you are building a house from such material with your own hands, then you should take care of maintaining the shape of window and door openings separately. In order for the form of windows and doors to remain unchanged during drying, it is necessary to pre-install special constructions in the openings - casing.
• If the construction is used professional timber natural moisture, experts recommend that the main work in the cold season. This is primarily due to the reduced risk of cracking during drying: the lower the temperature in the first two or three months, the lower the likelihood of cracking a damp tree.

Tip! To avoid the appearance of cracks in the summer, the instruction recommends that compensatory cuts be made on the workpieces.

• Another feature is the presence of a beneficial environment for the development of bacteria and fungi. On a dry tree, these parasites settle extremely reluctantly. Therefore, to protect the building you need to apply appropriate measures (to provide waterproofing, apply impregnation, etc.).

Pros and cons of a timber that has not been dried

In order to finally figure out which material to buy - a bar of natural moisture or dry - briefly summarize all the pros and cons.

Let's start with the shortcomings, because there are more of them:

• Shrinkage and craving. The higher the initial moisture, the stronger the frame will be deformed during the drying process. Attempts to perform the finishing of an insufficiently qualitatively dried house will lead to sad consequences - it’s not worth trying.
• During the drying process, cracks may form in the very mass of the beam. Again, it is very important to control the temperature regime when standing a log house, and this can be done only by scheduling work on the calendar.

• Wood, especially the ends of the boards, must be protected from precipitation and penetration of bacteria and fungi. Trying to save on bioprotective impregnation is not the best idea.

What sways positive quality profbrusa natural humidity, they are:

• By manufacturability and performance characteristics, it is almost not inferior to the dried material. Installation is just as easy, except that blanks of a similar size will be a bit heavier.

• But the cost of material with a natural moisture level is a significant plus. If the period of exposure for complete drying for you is not a critical factor, you can safely make a choice in favor of cost savings.

Conclusion

Houses from the profiled timber of natural moisture should be built if you want to reduce the cost of purchasing building materials. Of course, the time needed to erect a building will increase, but if you are planning a slow project with phased financing, you will not need to spend money on more expensive chamber drying material.
