Sawn treated softwood is wood that has been injected with chemical preservatives to protect it from rotting and of course parasites. The wood is placed in a vacuum storage tank that removes air and replaces it with a preservative. The most important thing you should know about this pressure treatment is that to this day, this process is the best way to avoid harmful putrefaction and insects, however, cannot prevent weathering and corrosion.

Although newer pressure-treated timber methods do now coat with a sealant to protect the wood from the weather and corrosion. The pressure treatment protects the wood from internal decay, while the sealant also protects the wood from external damage. The sealant in addition prevents the timber from drying too quickly, which can lead to excessive deformation.

Sawn treated softwood has been a valuable building material for thousands of years, however as the timber tends to rot, this limits its use for many applications. Natural wood products are susceptible to moisture, especially in environments that promote bacterial or fungal growth where boring insects are particularly challenging.  Although other building materials (such as stone, concrete, aluminum, or steel) can be used in place of wood in many harsh environments, they are often more expensive and difficult or less convenient to apply.

In order to overcome the limitations of natural wood and make it suitable for use in more extreme environments, pressure-treated wood was developed. To produce pressure-treated timber, one of several different chemical compounds can be compressed into the grain vast pressure, hereafter protecting it from elements, fungal growth, bacterial growth and pest damage.


Humidity resistance

Natural wood that is left in a damp or humid environment quickly becomes softer, causing fungi, bacteria and other microorganisms will take root and the wood inevitably slowly decompose. Pressure-treated timber uses one of several copper-based compounds. Copper is a natural fungicide that protects it from fungi and other microorganisms that causes wood to decay in damp environments. Following treatment, the wood can be used for a variety of applications, e.g. for decks that are constantly exposed to various elements, sill panels on possibly wet concrete and even as support columns for pillars and pillars where the wood is immersed further.

Fungous resistance

Even if there is only a very small amount of water, many different types of mushrooms can bind it to the wood and start to grow, transferring its root structure deep into the wood to slowly decompose it. When wood weakens, it can be hunted by other organisms, including insects and bacteria. Pressure-treated wood uses copper-based compounds (such as quaternary copper ammonium salts or copper azoles) to prevent the growth of fungi.

Fly resistance

In many areas, insects such as termites and wood ants are a major threat to any structure made of wood. Insects can easily penetrate the wood, weaken the strength of the wood, and ultimately cause dangerous structural problems, especially when the wood is exposed to a damp environment. The copper compound in the wood after pressure treatment can prevent insects from being damaged, and other chemicals (such as borate or rare arsenic compounds) can be added to further prevent insect activity.

If pressure-treated wood is used effectively in the construction process, it is placed in areas prone to insect activity. It can also form a barrier to protect the rest of the structure from insects, including untreated wood. In addition, other evil insects (such as cockroaches and spiders) can be prevented from remaining in the building.

High load capacity

The first advantage of wood is that its weight is relatively low with a high load-bearing capacity, so that a strong and light design is created. An example is a wooden house that was built on the smallest foundation.

Fast installation speed

Another advantage of wood is that it is quick and easy to install. This wood has no competitors. Dust-free, technology-free, easy to install, and at top speed. If you put the wooden floor in the cabin, you can also safely continue your work, which is different from concrete.

Natural wood sources

Another advantage of wood is worth mentioning – it’s natural source. His natural and human intimacy is based more on chemical reactions. Wood used for wood production can bring vitality and warmth to people, not to mention environmental protection. Because wood is a leader in covering walls and floors, home decoration products (such as floors, log houses and cladding) are possible.
