Sandwich panels with the fire-proof polyisocyanurate PIR Premier filler are designed for construction of big refrigerating groups, terminals and other buildings with the elevated fire safety requirements.
They have the best characteristics among the hydro and heat insulation materials, and are easy to mount. They can have smooth or profiled surfaces of any RAL colour.
PIR, or Polyiso, has more universal applications, such as:
- Refrigerators, cold and freezing rooms
- Vegetable and fruit storages
- A variety of agricultural facilities: cowsheds, pig farms, poultry houses, etc
- Logistic facilities, refrigerated warehouses
- Production and office buildings, workshops
- Service stations, hangars
Sandwich panels with PIR Premier are also used to modernise and improve energy efficiency of buildings constructed from other materials.
ProfHolod PIR Premier sandwich panels - three-layer panels with thermal insulation made of fire-resistant polyisocyanurate foam on a customised PIR Premier system from the best foreign components. Sandwich panels with PIR Premier allow reduced costs for cooling or heating due to thermal conductivity of 0.022W/m*K, and comply with the European standard EN14509.
The PIR Premier system was developed in the ProfHoloda R&D center in 2016. According to PU Europe, 115mm-thick PU foam saves 162 kWh per sq. m of insulated surface. The unique, deepest 20mm docking profile on the market guarantees no cold bridges. Panels have a 50-year service life.
What is PU?
Polyurethane foam is a lightweight and durable material that was invented in 1937 in Germany. Polyurethane is made up of small closed cells. 3% of its volume is solid material, and 97% filled with gas. As a result polyurethane foam perfectly holds the required temperature: thermal conductivity of gases is lower by tens and hundreds of times compared to solid materials.
How is PIR Premier different from other PIR systems?
For more than 3 years Profholod's custom-made PIR Premier blend guarantees the quality of sandwich panels and PIR Plita® insulator: thermal conductivity and physical and mechanical characteristics. The reason is PIR Premier was created specifically for the company's lines. Whereas most manufacturers of sandwich panels with polyurethane use universal foam from a limited range of manufacturers.
Profholod created PIR Premier in partnership with international corporations Dow, BASF, Evonik in 2016. The system is certified according to the European standard EN 14509 and, since 2017, all ProfHolod sandwich panels with PU are CE marked.
To guarantee the quality of the sandwich panels and PIR Plita® insulator, the PIR system components are carefully selected in Profholod's R&D Center, established in 2016.
Through 2019, the company produced more than 5,000,000 square meters of sandwich panels with PIR Premier, with over 5,000 tons of polyol systems.
PIR Premier insulation sandwich panels deliver resistance of more than 185kPa when testing compressive strength at 10% deformation, and more than 160kPa at break at a density of 40kg/m3.
