The article tells about the advantages of construction of PIR and PUR sandwich panels for farmers and entrepreneurs engaged in agriculture.

In connection with the policy of import substitution in Russia, a growing number of people who have decided to take up farming, growing vegetables and processing of agricultural produces. On the market there are a large number of players, and the competition among the enterprises of small and average business is sharp as ever. Therefore, before any entrepreneur has an important task to reduce all production costs.

What are the requirements for the vegetable and agricultural complexes

Alexei Gorokhov, Executive Director of the Association “NAPPAN”:
“We can formulate the main characteristics that should have a modern agro-industrial complexes. It is a high speed of construction for low-cost, economical and trouble-free operation for at least 50 years.”

Contemporary market conditions impose certain requirements for energy efficiency of such structures. Since more heat loss through the building envelope, increasing energy costs. This, in turn, leads to higher costs of production and increase the ultimate cost of production.

Also to the fruit and vegetable storage have strict requirements for temperature and humidity level. For example, potatoes, eggplant, cucumbers, tomatoes and peppers stored at temperature from 0 to + 8 °C. And this temperature regime should be maintained consistently all the time.

To prevent spoilage of products, it is necessary to build sealed greenhouses, with controlled or modified atmosphere with low oxygen content. This increases the shelf life of products from 2-3 to 6-8 months.

In addition, the final cost of products is influenced by initial production costs. To cut costs, reduce material capacity of the constructions. Therefore, agricultural buildings should be build from a lightweight and durable material having a low coefficient of thermal conductivity.

Also the speed of construction negative impact of atmospheric phenomena — rain, snow, and so-called “the human factor”. Consequently, the material from which, for example, built a vegetable store, or animal farm must be waterproof and all-weather, and all the processes simple and straightforward for installers.

The sandwich panel consists of three layers. It is facing (steel sheet), insulator (foam), coating (steel sheet). Moreover, in contrast to panels based on mineral wool, polyurethane foam is sprayed and will not stick to the veneer. This creates a high strength connection.

Gorokhov Alexei:
“Foam used in the PIR and PUR sandwich panels, is a polymer with a low coefficient of thermal conductivity and polystyrene, preneporochnoe structure. Therefore, the material is not subject to vlagonakopleniyu and bioporazheniyam”.

PIR is a kind of flame retardant polyurethane foams, the so-called thermosetting polymer is a polyisocyanurate. Under high temperatures, the outside material is formed Carbonari preventing the spread of flames. Therefore, PIR panels, you can erect structures with particularly stringent requirements for fire resistance, for example, the roof.

Novikov Yuri, expert of the Association “NAPAN”. The speaker representing the manufacturer of sandwich panels:
“Polyurethane foam sandwich panels this is a modern building material made in high-tech industrial production. Therefore, all material specifications, fully meet the specifications of the manufacturer. Of PIR/PUR sandwich panels, characterized by high teplopotreblenija, build energy-efficient structures — the so-called building-thermoses. This reduces the cost of heating the premises”.

Sandwich panels polyurethane-based, can in the shortest possible time to build vegetable storage, cold storage, processing production. During the construction of completely missing the so-called “wet processes”. You do not want to mix the solution, etc. This feature, as well as durability polyurethane foam to moisture allows you to mount design, regardless of the time of year.

While the panels have a relatively low weight, which reduces logistics costs. Also reduced: the material of the metal framework, transportation costs, and labor costs for installation.

Due to lower weight, PIR panels are easier to manipulate at the construction site. And due to the higher stiffness than that of panels based on mineral wool, reduces the risk of damage to the long panels are “on a break” during installation.

Ilushkin Vladimir, expert of the Association “NAPAN”. The speaker representing the manufacturer of sandwich panels:
“Because farmers and agriculture are closely connected with food products, it is necessary to eliminate the risk of mold and bacteria in the heater. PUF panel, which is especially important for agriculture, do not accumulate moisture. It’s chemically inert and biologically stable material. It does not decay with time. Resistant to acid and alkaline environments. Does not rot, is not susceptible to the harmful effects of rodents and insects”.

The most important advantage of PU foam sandwich panels is a hermetic joint, because the panels have a labyrinthine castle, they are joined “at the pins”. Therefore, no additional zapisivat connection, you have built a solid insulating bezrazlichny circuit, simplified all the technological operations. Butt does not get wet, which means that it does not break at low temperatures, increases the speed of construction, with consistently high quality of work that can be maintained all year round.

Important: to break the “cold bridge” on the fasteners, in refrigerating chambers are used termobloki — * * * PIR/PUR sandwich panels, providing thermal-, hydro – and gas tightness at the place of mounting screws. Next, the drilled hole zapisyvaetsya technology that provides a low thermal conductivity of the node, which is then covered with decorative thermocapacitor.

Summing up

On the totality of technological and consumer factors, PIR and PUR sandwich panels have no competitors. When using PUF sandwich panels, significantly accelerated the construction of agricultural complexes. Long life material, easy and well proven technology of installation of the panels, allow to build houses or farms, which in the future will not require repair and, therefore, reduced all the expenses for their operation in the long term.
