The domestic construction sector has undergone significant changes in recent years under the influence of the world market. In particular, this applies to technologies for the construction of private houses. Canadian construction ideas, which suggest the rapid construction of strong, environmentally friendly and energy-efficient houses, have become especially in demand. Along with this, the production of SIP panels is developing, which act as the main material for such buildings. The manufacturing technology is not only distinguished by high profitability, 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 type of wood-shaving building material. I must say that the segment of multilayer panels and in isolation from Canadian technologies is quite popular these days, as it allows you to quickly implement a project with minimal cost. Also, relatively high technical and operational indicators of the material stimulate interest from the consumer, which, in turn, motivates the business. The production of SIP-panels differs precisely in its orientation to the popular technology of panel-frame 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 prices, however, in terms of high-quality operational 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 characteristics of the material. In practice, this improvement is expressed in strength, resistance to weathering and mechanical stress.
It is clear that high technical and physical characteristics are achieved during the complex process of processing raw materials. The full technological cycle provides for the implementation of three main stages - assembly, cutting and gluing. The first two stages of manufacturing are carried out on the center line, and the third on separate equipment. Assembly activities, in turn, involve the combination of polystyrene sheets, OSB and PSB boards. In parallel with this, cutting of blanks is also carried out in accordance with the originally conceived dimensions. After this, the final stage begins, in which polyurethane or other glue is used, which provides for the Canadian production of SIP panels in its standards. The technology also allows the possibility of simultaneous bonding of several panels, but this already depends on the capacities of a particular workshop. Physically, this process is carried out by pressing machines that provide a load of about 5 tons.
Raw materials for panels
In accordance with the requirements of the technology, the basic set of the raw material base should include oriented particle boards and non-shrink suspension polystyrene foam sheets. As a binder component, a polyurethane composition is used. However, it is the glue base that is the most controversial ingredient in this kit. The fact is that the production of SIP panels gives the final product the necessary margin of safety, but environmental cleanliness is still being questioned. Today, new adhesives are being developed that can provide a high bonding function, but at the same time they will have less harmful effects. Perhaps the advent 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 supplying communication nodes, a pressing machine, a cutting point, etc. The cost of the finished lines varies from 2 to 3 million rubles. Of course, this option is more likely to be suitable for enterprises that already have the ability to create a new conveyor. If it is planned to organize a small private line, then it makes sense to arrange separate production of SIP panels. Business from scratch in this case is more promising and retains all opportunities 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, press and thermal knife.
The main expense item may be equipment. In the case of the purchase of a finished workshop, the costs will amount to an average of 2.5 million, and if we are talking about self-assembly, we can talk about 200-300 thousand. Of course, in addition to this, we should add the costs of auxiliary equipment, 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 for these investments, since one unit of material makes an average profit of 1 thousand. Depending on the productivity, investments can be paid back either in a few months or in a year.
Material Sales Channels
The basis of the client base can be private construction companies that are engaged in the construction of wooden houses. This segment is still in demand in the Russian market, and the fashion for Canadian technology 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.
Although stone and brick houses are still associated with quality, durability and reliability, alternative construction technologies constitute a serious competition for them. If comparisons in terms of strength do not always count toward panel-frame technologies, then affordability and energy efficiency are the indisputable advantages that homes made of SIP panels have. The production of this building material is largely focused on Canadian standards, but Russian process modifications are increasingly appearing. The departure from the classical idea is associated with differences in the characteristics of wood materials. Russian forestry allows the use of a high-quality raw material base, which in some respects outperforms North American products.
