Modern people have long been accustomed to using apartments in high-rise buildings as housing. They are built of foam concrete and brick. To insulate the walls in these buildings are increasingly used materials of synthetic origin, which, although not harmful to human health, but sometimes are not able to perform their direct functions.
That is why residents of megacities are trying to move to houses made of natural wood. If this is not possible, then you can build a house in the country. For this, logs or timber, insulated with jute thermal insulation, are usually used.
Varieties and features of jute insulation
Before you lay the jute on a beam, you should familiarize yourself with the varieties and features of this material. It has a natural origin, therefore it is close to dry wood. We can assume that jute is a dry grass, a spinning crop that successfully replaces flax.
Modern jute thermal insulation has excellent characteristics, among them:
- ability to seal joints;
- biological inertness;
- lack of an unpleasant smell;
- tight fit to the beam and log;
- steam throughput;
- resistance to decay.
Additional benefits
Jute insulation is also quite dense. If you purchase a quality jute, then its density will be 60 g / m 2 , while the layer thickness can be up to 10 mm. The fiber length does not exceed three centimeters.
You can meet jute insulation in several varieties, in the first case, up to 15% of felt is added to the material, in the second - flax - up to 50%. Pure jute and jute with flax impurities are produced in rolls of different widths.
Selection and styling
Before you lay the jute on the beam, it is important to choose the right material. It is only necessary to start the insulation work some time after the completion of the construction of the house. During this period, the wood will reach the desired moisture level, and the walls will sit down. But even after thermal insulation, the interventional heater will allow moisture to pass from the beam or log.
Using thermal insulation, it will be possible to fill the joints to prevent the formation of cold bridges. When choosing a thicker seal, you will ensure ease of installation. The material should be placed in the connecting groove so that it does not move, and after it is pressed by a log, the insulation must be fixed with a stapler, installing fasteners at a distance of 250 mm. If you purchased too wide a tape, then its edges need to be turned inward. The tape should also be located in the bowls.
Features caulking
Laying jute on the beam is a prerequisite for insulation. Some masters believe that there is no need to caulk the joints, but in practice this procedure is still required. Once the log is seated, it can be tightly twisted. On the one hand, a 0.5-cm gap is formed, while on the other hand, the seal is tightly clamped.
In this case, caulking helps, in which it is best to use tow or tape. This should be done only a year and a half after the construction of the house. In some cases, laying an interventional insulation does not imply tucking the ends of an overly wide tape. In this case, the ends will hang from two sides. After the house shrinks, the hanging ends can be hammered into the joints.
However, in this case, you may encounter a problem, which is expressed in the fact that after 2 years the sealant decays under the influence of ultraviolet radiation, moisture and wind. Between the joints, in the end, you will have to hammer in low-quality material, which does not always allow complete sealing to be achieved.
Why you should choose a jute compactor
If you have not yet decided whether to lay the jute on the beam or any other material, then you should familiarize yourself with this issue in more detail. First of all, they begin the construction of a wooden house, pursuing the main goal - environmental friendliness. For caulking joints between the crowns, you can use other materials, namely:
- moss;
- flax batting;
- liquid acrylic sealants;
- flax rope.
One of the advantages of jute over the above materials is that it does not wrap on a drill. The insulation has such a structure that when drilling the metal does not adhere to the thermal insulation, which is very convenient during operation. In addition, the jute is ready to serve exactly as long as a wooden house stands. The declared term of operation of thermal insulation is 75 years.
Some owners of wooden houses do not use jute to warm the crowns of timber, preferring acrylic sealant. Experts believe that the appropriateness of this approach may raise doubts. Although the joints will not let the cold through, the walls will lose their ability to breathe. Steam will cease to circulate and wood may begin to rot.
Styling features
You can independently carry out the laying of jute on a beam, the features of these works require the observance of several rules. It is important to lay the tape on the connecting groove. It should fill the space of the bowls.
Without bends, the material is stacked if the house is built from an ordinary log or glued profiled beam. Sometimes the insulation has double-sided bending, this solution is suitable for houses made of chopped or rounded logs. The material can also be laid with one-sided folding, this method is suitable for structures made of planed timber.
It is important to take into account the dependence of the thickness of the insulation on the material of the walls. If it is intended to use glued beams during construction, then the insulation should have a thickness of 0.5 cm. When the system is based on a round log, it is necessary to purchase insulation with a thickness of 0.8 to 1 centimeter. If you plan to use a chopped log, then the jute should have a thickness of up to 1.5 cm.
Technology of work
Quite often, novice masters ask themselves how to correctly lay a beam when using jute insulation. The work will consist of several stages. The first involves the distribution of the insulation along the inter-crown grooves, at the next stage the material is fixed using a stapler. Next, the next log or beam is laid, and at the end of the crowns the thermal insulation is cut off with scissors.
As soon as the laying of the log house is completed, the protruding parts of the insulation can be submerged inside. It is important to pay particular attention to the fact that the grooves must be completely filled with thermal insulation. When installing log walls, which will be assembled manually, it is necessary to select the thermal insulation depending on the quality of the interventional joints. The neater and denser they are, the easier it will be to insulate the walls. But, as practice shows, the elements of the log house, assembled by hand, are of average quality. In this case, it is important to know how to properly lay the jute on the beam.
Mentioned insulation material is combined with an analog in the form of tow. Lay out the insulation with your hands and placed in the cuts and grooves. In the place where the thickness of the jute tape is enough, you can fix the tow with a stapler.
Recommendations for laying jute between logs and beams without longitudinal grooves
Quite often, lately, home masters have been laying jute. At the same time, a profiled beam or a rounded log is insulated in one layer. When using conventional timber, the thermal insulation must be laid in two layers. This rule will be more applicable to timber houses that do not have longitudinal grooves. This building material is deprived of recesses for insulation, it is not possible to form a thermal lock in it, so it will be subject to blowing.
Conclusion
A prerequisite for the construction of a wooden house is the laying of jute on a beam. Interventional insulation made from natural materials is preferable to synthetic sealants, which, although easy to use, do not allow the wood to breathe. As practice shows, the technology of warming wooden residential structures, which were popular among our ancestors, is not only more familiar, but also more reliable for a Russian resident.
