Larch is an excellent tree for creating durable houses and foundations for them. In this article, we will talk about all the advantages and disadvantages of larch profiled beams as a material for housing construction. What is the difference between glued laminated timber and profiled timber, and is it advisable to use it when building a turnkey house, we will give an approximate calculation of the price for a timber as of 2020.
Larch is a wonderful material, the properties of which people have appreciated for a long time. During the construction of the Italian city of Venice, the builders used larch piles to lay the foundation.
Centuries later, the locals decided to check if the foundation was intact. And lo and behold! The wood not only did not rot, but became hard as stone, despite the influence of sea water. It could not be damaged with an ax; only small scratches remained on the surface.
Choosing a profiled larch bar for construction, you must clearly understand that, despite all the beauty of this wood, it is extraordinary the density of the material can play a cruel joke.
After 15 - 20 years, in such a house you cannot even make elementary repairs. Neither hammering a nail into a tree from the inside to hang, say, a new painting, nor decorating the facade in a different way. Larch turns into stone.
As we already said, water has no effect on larch timber. The material does not grow moldy or rot. Based on this, experts recommend making the lower crown, which is located in close proximity to the concrete base, to be made of larch. This way, you protect the top crowns from rot, mildew and moisture, contributing to the longevity of your home.
Larch is an impeccable material for laying floors, installing verandas, railings and steps. The end result is a wonderful home that will not lose its beauty over the years, or even centuries.
For the production of profiled timber from larch with natural moisture, builders use the technology of planing and milling wood along the entire length.
Such material is made only from a complete array.
Thus, at the initial stage, high quality material is obtained. Larch is much more difficult to cut due to its high hardness, so the price of the material is quite high. Builders recommend using dry profiled larch timber for building houses. The material of natural moisture indicates that the houses will shrink for a long time by 2 - 3%.
Glued larch timber differs from profiled, processing technique and high performance characteristics.Houses made of glued larch timber are more reliable and durable. A distinctive feature of this material is that it does not rot, does not crack, retains its properties even in regions with a harsh climate, is resistant to moisture and natural wear and tear.
The price of glued laminated timber depends on the manufacturer, as well as the color of the material. The color palette is quite diverse and able to please even the most demanding customer. Larch glued beams have antiseptic characteristics typical of natural wood. Insects and rodents do not touch larch.
Houses made of different types of larch timber have an excellent level of thermal insulation, depending on the massiveness of the walls.
But, despite this, larch houses are a little cooler than, for example, cedar or pine houses. And all because of the high density of wood.
In Russia, larch is a fairly accessible material. It is used to create underground premises, as well as supporting elements for the construction of mines, etc.
Larch is a needle that contains a large amount of resins, and due to this it has such high biological characteristics. Resins prevent damage to wood by insects and rodents, and also make it extremely hard over time. Regardless of the flammable properties of resins, larch has fireproof properties.
But, in any case, it requires processing with special fire-fighting substances.
Larch smells very nice of needles. Those who already live in such houses note the beneficial effect on the microclimate in the room, and do not want to decorate the walls from the inside in any way in order to enjoy these aromas for an extremely long time.
An innumerable number of reviews from the owners of such houses in various forums, as well as to photos and videos of houses made of larch timber, prove that untouched natural facades and interior decoration are more attractive than finishing with modern materials. This has its own charm - to preserve natural beauty and be a part of nature. Larch log cuts have a wonderful structure of amber-pink and red-brown undertones. The central solid part of the trunks captures the main surface of the section, its sapwood is relatively narrow.
Houses made of profiled larch timber 200 x 200 cm are highly environmentally friendly. They do not need to be treated with antiseptics. Outwardly, such houses are very beautiful and monumental.
The durability of such housing will delight more than one generation in the family.
The antioxidants contained in larch have a beneficial effect on human health, prolonging life, and preventing the development of various diseases. In addition to the above, such houses tolerate frost and temperature changes well, and are easy to use.
The paradox of such a wonderful material as larch timber in its positive aspects.
The high concentration of resin makes wood processing quite difficult. The viscosity of the structure forces the use of expensive equipment and sophisticated technologies.
Saws and knives become blunt very quickly when cultivating larch timber.
The density of the structure makes the process of logging and transportation heavier. The main supplies of larch timber are made from Siberian forests.
And there, as you know, the easiest way to transport wood is rafting down the river. Due to its heavy weight, larch often sinks, but it is also an expensive pleasure to take out by special vehicles. These nuances affect the pricing policy, so a larch house cannot be cheap. For example, in the middle zone of the Russian Federation the price of 1 m³ of larch timber fluctuates around 14,000 rubles. To this price, you need to add the cost of work - about 6,000 rubles.
The high moisture content and density of the trunk means that the wood will definitely dry out. Moreover, this happens unevenly along the entire length of the bar.
In order to minimize the negative consequences of this process, the ends should be coated with oil paint, drying oil, clay or lime, immediately after the felling.
Wide larch planks are warped and cracked on the outside. In order to minimize this disadvantage, the material is radially sawed.
Profiled larch board eventually becomes hard like a stone, which makes it difficult to carry out finishing work.
It is believed that larch timber is not the best material for building houses in the cold regions of the country.
This is explained by the fact that dense material heats up for a very long time. But some experts consider this statement to be very controversial, since much depends on the quality of the timber and the construction technology.
Larch - the queen of the forest has a life span of 600 years, and the height of a mature tree can reach 50 meters ..
. From large-caliber logs, you can build a monolithic frame, without the need to splicate the material. A house made of such wood will last for about 200 years.
The complexity of the whole construction process lies in the difficulties of transporting timber. The modern technological process makes it possible to use larch as a profiled and glue bar.
For decoration of houses - internal or external, flooring, terrace and deck larch boards, lining, euro lining, block house are used.
Often builders do not advise to build houses only from larch beams. The best option is considered to be the use of this material together with cedar or pine. It is also recommended to construct combined frame buildings.Thus, it is possible to reduce the cost of building a wooden house and facilitate its further use as a permanent home. It is rational to use larch elements during construction where there is a risk of contact with moisture: lower crowns adjacent to the foundation:
This will prevent the formation and further spread of mold, mildew, rot to the upper elements and will provide the structure with durability.
The price of a turnkey larch house, built in a few months by professional builders, will result in approximately 1 million rubles on a small area of 60-80 m2. Accordingly, for buildings on a larger square, with an interesting architectural form, the price will be several times higher.
The price for 1 m² of larch wall depends on the diameter of the timber. The estimated price for 1 m³ as of 2018 ranges from 20,000 rubles. This is the cost of material, excluding construction work. Also, the cost of building a house from larch depends on the availability of the project.
Such projects are prepared by specialists taking into account all requests for design, ventilation and air conditioning systems, wiring and lighting. A good heating system will make larch housing warm and comfortable for living.
The coldness of the floor and walls is felt only when it comes into contact with wood. You can dress warmly during the cold season and move the beds away from the walls and enjoy the pleasant indoor air, which is great.
The floors in the house can be made of cedar or pine, for those who are already very thermophilic.
