The independent testing laboratory of the Research Center for Construction Technologies and Materials has confirmed the durability of polyisocyanurate PIR inside sandwich panels. The thermal conductivity of the PIR foam in the sample of PH Insulation sandwich panel remained at 0.021 W/(m*K) after 8 years of operation, according to the tests.
The sandwich panel’s sample with PIR core has been in use in the facade of the PH Insulation door manufacturing building, located in a with high humidity environment.
The first in Russia independent test of the performance characteristics of polyisocyanurate foam in sandwich panels, that have served as a building envelope for 8 years, fully confirmed the information known to the PIR manufacturers. The durability of PIR is indeed unique, sustaining its thermal conductivity levels over long terms.
Being experts in energy-saving technologies, we have been aware of these qualities of PIR for quite some time, and that is precisely why we recommend PIR to our clients for construction and insulation. PIR systems, especially PIR Premier, effectively save both energy and money over the long term

The measurement of thermal conductivity was conducted according to the Russian standard GOST 7076-99 “Building Materials and Products. Method for Determining Thermal Conductivity and Thermal Resistance under Steady-State Thermal Conditions”. During the test at the Construction Technologies and Materials center, the thermal conductivity of the PIR insulation was measured in its natural moisture state across the entire surface of the sandwich panel using the λ-Meter EP500e device.
The new tests confirm conclusions made by PH Insulation’s R&D center in 2023. Last year PH Insulation’s specialists tested a sample of a wall sandwich panel with PIR, which had been in use since 2015 as an enclosing structure of PH Insulation’s production workshop in the Moscow region.
