Sandwich panels PIR Premier "ProfHolod" - three-layer panels with thermal insulation
from fire-resistant polyisocyanurate foam
on a customized PIR Premier system
from the best foreign components.

Sandwich panels with PIR Premier allow you to reduce the cost of cooling or heating due to thermal conductivity of 0.0194 W / m * K, comply with the European standard EN14509. The PIR Premier system was developed at the ProfHoloda R&D center in 2016 and is the best-selling PIR system in Russia.

According to PU Europe, 115 mm thick PU foam saves 162 kWh per sq. m of insulated surface.

The unique, deepest 20 mm docking profile on the market ensures that there are no cold bridges.

Service life of panels: from 50 years.

Sandwich panels with insulation made of PIR Premier polyisocyanurate foam are a modern hydro- and heat-insulating building material.

The main difference between PIR and PUR polyurethane foam is the high fire resistance confirmed by certificates: G1, EI45. 

Foam polyisocyanurate PIR Premier "ProfHolod" from the best foreign components insulates better than other heaters: its thermal conductivity coefficient is only 0.0194 W / m * K.

Polyisocyanurate foam PIR

Polyisocyanurate foam or PIR is a modified polyurethane foam or polyurethane foam. Like PUF, PIR is produced by the reaction of a polyol and an isocyanate. In this case, the components are consumed in such a way that the isocyanate index exceeds 290, which corresponds to a ratio of at least 2: 1 (isocyanate is twice the amount of polyol). The reaction between polyol and isocyanate is exothermic. During the reaction, heat is released and polyurethane bonds are formed. Free molecules of excess isocyanate interact with each other in the presence of a catalyst at temperatures above 160 degrees Celsius, forming stronger, more stable, polyisocyanurate bonds. The result is polyurethane foam reinforced with polyisocyanurate bonds.

Due to this chemical structure, PIR retains all the positive properties of polyurethane foam: low thermal conductivity, vapor and water resistance, durability. Due to its structure and the content of fire retardants in it, PIR does not support combustion - it self-extinguishes when the fire source is removed. Compared to polyurethane foam, PIR has higher tensile and compressive strengths and can be used where increased requirements are imposed on these properties, for example, in the structure of buildings that are subject to strong wind loads.

Customized PIR Premier "ProfHolod" system

Since 2016, the customized PIR Premier blend has been guaranteeing the quality of ProfHoloda and PIR Plates ® sandwich panels: thermal conductivity and physical and mechanical characteristics. Because it is designed for use on the automatic lines for the production of sandwich panels installed in ProfHolod. Most manufacturers in Russia and around the world use universal solutions from a limited number of producers of raw materials systems.

The PIR Premier system is the best-selling system in Russia. The system is certified according to the European standard EN14509, all ProfHoloda sandwich panels on this system have the CE mark.

Sandwich panels with PIR Premier demonstrate a resistance of more than 185 kPa when tested for compressive strength at 10% deformation and more than 160 kPa at break at a density of 40 kg / m3.

To guarantee the quality of insulation, PIR Premier components are carefully selected at the ProfHoloda Research Center. The selection criterion is the physical and mechanical properties of the foam, better spreadability, low thermal conductivity - only 36 parameters. Tests are carried out on water absorption, dimensional stability and weight loss in accordance with GOST for cellular plastics.

To introduce the recipe on the ProfHolod line, he conducted about 100 tests of 9 catalysts from 5 suppliers from all over the world: in order to select the optimal ratio of catalysts, pressure, components and press speed on the ProfHolod automated lines.

To ensure the quality of every square meter in every batch, the company's R&D center online monitors the composition and characteristics of the sandwich panels by monitoring 14 indicators from the line.

To control the properties of PIR Premier at the molecular level, at the beginning of 2020, ProfHolod installed the world's most modern polyester production unit from the German company H&S.

Because ProfHolod believes that it is here, in Russia, that high-tech products can be produced in order to save energy and money for partners and clients.

Areas of use

Sandwich panels with PIR Premier polyisocyanurate foam are used for construction:

• large refrigerating and freezing warehouses
• production, warehouse and logistics complexes
• shopping malls
• sports facilities, swimming pools, cinemas
• commercial real estate objects
• food industry facilities

Sandwich panels with polyisocyanurate foam insulate:

• foundation and floor
• external walls: both outside and inside, in particular as part of a renovation
• interfloor and attic floors

Due to the unique chemical properties, sandwich panels with PIR Premier are indispensable for construction:

• refrigerating and freezing chambers
• warehouses of aggressive or chemically active substances
• liquid gas storage facilities
• other similar structures

Advantages of sandwich panels filled with polyisocyanurate foam

You will build a building in a short time at any time of the year and in any climatic conditions.If
you are building a building from sandwich panels with polyurethane foam or polyisocyanurate foam, the construction time is reduced by more than 10 times compared to traditional materials: brick, concrete. Sandwich panels can be mounted on a metal frame at any time of the year, even in the Far North: by minimizing "wet processes".

You can be sure of its fire resistance.
PIR Premier meets the main requirement for insulation: fireproof, nonflammable, extinguishes when exposed to fire.

You will reduce the cost of foundation
Sandwich panels with PIR Premier and PUR Classic insulation reduce the total weight of the building by 10 or more times compared to structures made of bricks, concrete and other building materials.

Increase the usable area
Polyurethane foam increases the interior surface of buildings by insulating it with a thinner layer in the same way as thicker layers of other materials.

You will reduce transport costs
Lightweight and durable PIR Premier PUR Classic insulated sandwich panels are cheaper and easier to transport than tons of bricks, cement, sand, reinforced concrete slabs or lumber.

Your building will last 50 years or more while maintaining all the energy efficiency indicators.According
to research carried out by the European association PU Europe, the thermal conductivity of a polyurethane foam sample that has served 33 years is fixed at an almost unchanged level of 0.0272 W / (m * K) with a slight decrease in thickness from 60 to 59/05 mm.

Your building will look modern
ProfHolod sandwich panels are manufactured in the factory. Their surface does not need any external or internal finishing. And using a wide range of colors of metal, you will build a building in the corporate colors of your company, satisfying the wishes of the designers.
