1.2 million m²
B1 grade or above · up to 250 °C
VIKKINS’ PUR production line is equipped with an advanced six-component multi-injection foaming system and automated controls from Siemens. The system adjusts in real time based on ambient temperature to ensure consistent panel quality.
Our PUR panels feature high strength, energy efficiency and environmental friendliness — ideal for modern insulated building applications.
PIR panels developed by VIKKINS are produced with an enhanced formulation using excess isocyanate and a high isocyanate index, creating a compact cross-linked structure. The result: greater thermal stability and fire resistance, withstanding temperatures up to 250 °C for short periods.
PIR foam offers low flammability (B1 grade or above), excellent resistance to flame penetration, smoke toxicity, and deformation. Compared to standard PUR foam, PIR panels deliver superior thermal performance, better fire resistance and lower smoke emissions — ideal for high-standard insulation applications.
