The domestic construction sector has undergone significant changes in recent years under the influence of the global market. In particular, this applies to technologies for the construction of private houses. Canadian building ideas have become especially in demand, involving the rapid construction of strong, environmentally friendly and energy-efficient homes. Along with this, the production of SIP panels is also developing, which act as the main material for such buildings. The manufacturing technology is not only highly profitable, but also, in general, allows you to get a decent result in the form of a modern residential facility.
What is a SIP panel?
In essence, this is a kind of wood-shaving building material. I must say that the segment of multilayer panels, even apart from Canadian technologies, is quite popular these days, as it allows you to quickly implement a project at minimal cost. Also, consumer interest is stimulated by relatively high technical and operational indicators of the material, which, in turn, motivates business. The production of SIP panels is distinguished precisely by its focus on the popular panel-frame technology.construction. These are three-layer structural sheets, which also have high-quality external insulation.
Traditionally, frame houses won due to the high speed of construction and affordable price, however, in terms of quality performance parameters, they were noticeably inferior to classic log cabins. The modern production of SIP panels has made it possible to solve this problem by improving the physical parameters of the material. In practice, this improvement translates into strength, weather resistance and mechanical stress.
Production technology
It is clear that high technical and physical characteristics are achieved during a complex process of processing raw materials. The full technological cycle involves the implementation of three main stages - assembly, cutting and gluing. The first two stages of production are carried out on the central line, and the third - on separate equipment. Assembly activities, in turn, involve the combination of polystyrene foam sheets, OSB and PSB boards. In parallel with this, the workpieces are also trimmed in accordance with the initially conceived dimensions. After that, the final stage begins, in which polyurethane or other glue is used, which provides for the Canadian production of SIP panels in its regulations. The technology also allows the possibility of simultaneous gluing of several panels, but this already depends on the capacity of a particular workshop. Physically, this process is carried out by pressing machines that provide a load of about 5 tons.
Raw material forpanels
In accordance with the requirements of the technology, the basic set of raw materials should include oriented strand boards and non-shrinking suspension polystyrene foam sheets. A polyurethane composition is used as a binder. However, it is the adhesive base that is the most controversial ingredient in this set. The fact is that the production of SIP panels gives the final product the necessary margin of safety, but environmental friendliness is still being questioned. Today, new adhesives are being developed that can provide a high binding function, but at the same time will have less harmful effects. Perhaps the emergence of a new and cleaner glue will give a new impetus to the development of technology.
Equipment for the production of SIP panels
There are two approaches to organizing a production line for SIP panels. In the first case, it is planned to install a fully equipped complex with all the necessary units for the manufacture of building materials. Such a mini-workshop includes supply communication units, a pressing machine, a cutting point, etc. The cost of finished lines varies from 2 to 3 million rubles. Of course, this option is more suitable for enterprises that already have the ability to build a new conveyor. If it is planned to organize a small private line, then it makes sense to arrange a separate production of SIP panels. Business from scratch in this case is more promising andretains all the possibilities for further expansion. Those who wish to organize such a workshop will need a small room in which it will be possible to install a cutting machine, a press and a thermal knife.
Financial investments
Equipment can be the main expense. In the case of the purchase of a finished workshop, the costs will average 2.5 million, and if we are talking about self-assembly, then we can talk about 200-300 thousand. Of course, in addition to this, you should add the costs of accessories, rent, regular purchase of raw materials and maintenance. About 50-70 thousand per month will also go to these points. However, the production of SIP panels quickly pays off these investments, since one unit of material on average brings a profit of 1 thousand. Depending on productivity, investments can be recouped either in a few months or in a year.
Material distribution channels
The basis of the client base can be private construction companies that build wooden houses. This segment is still in demand on the Russian market, and the fashion for Canadian technologies has only expanded the range of services of such enterprises. Also, the production of SIP panels can be focused on the supply of individual developers who plan to independently implement projects. As practice shows, the possibility of direct interaction with the manufacturer of building materials provides a great advantage for consumers of different levels.
Conclusion
Although stone and brick houses are still associated with quality, durability and reliability, alternative building technologies are serious competition for them. If comparisons in terms of strength do not always take into account panel-frame technologies, then affordability and energy efficiency are the undeniable advantages that houses made of SIP panels have. The production of this building material is largely focused on Canadian standards, but Russian modifications of the technological process are increasingly appearing. The departure from the classical idea is associated with differences in the characteristics of wood materials. Russian forestry makes it possible to use a high-quality raw material base, which, in some respects, outperforms North American products.
