PUR

Polyurethane Core

La ligne de production PUR de VIKKINS est équipée d'un système avancé de moussage par multi-injection à six composants et de commandes automatisées de Siemens. Le système s'adapte en temps réel en fonction de la température ambiante afin de garantir une qualité constante des panneaux.

Nos panneaux en PUR se caractérisent par leur grande résistance, leur efficacité énergétique et leur respect de l'environnement — ils constituent donc la solution idéale pour les applications modernes de construction isolée.

PIR

Polyisocyanurate Core

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.

Buildings demanding insulation, fire safety and hygiene

01

Cold Storage & Freezer Rooms

Excellent thermal insulation and vapor sealing for facilities holding −30 °C interiors with zero condensation through the envelope.

02

Food & Pharma Processing

Hygienic, easy-to-clean PE/PVDF surfaces compatible with GMP environments. Closed cell rate > 97% blocks mold ingress.

03

Industrial & Workshop Roofs

Fast-track installation over portal frames, B1-grade fire rating, and superior soundproofing for noisy production environments.

04

Logistics & Distribution Hubs

Long-span panels (up to 150 mm thick) deliver lower U-values down to 0.20 W/m²K — cuts HVAC running cost across high-bay warehouses.
