PIR Sandwich Panels (Polyisocyanurate Insulated Panels) represent a next-generation insulation solution that combines enhanced fire performance with ultra-high thermal efficiency. Compared to traditional PU and EPS panels, PIR offers a more stable chemical structure, improved fire behavior, and lower thermal conductivity. These panels are widely used in cold chain logistics, pharmaceutical clean rooms, and energy-efficient industrial buildings, where both safety and insulation performance are critical.

FAQ
1. What makes PIR better than PU panels?
PIR has a more stable polymer structure, offering better fire resistance and lower thermal conductivity than PU.
2. Is PIR suitable for cold storage projects?
Yes, PIR is one of the best materials for cold rooms, especially for temperatures below -18°C.
3. What joint systems are available?
We provide:
Camlock system (for cold rooms)
Hidden joint system (for buildings)
4. How does PIR perform in fire conditions?
PIR forms a protective char layer, slowing flame spread and reducing smoke.
5. Can PIR panels be used in food or pharmaceutical industries?
Yes, with stainless steel or coated surfaces, they meet hygiene standards.
6. What is the lifespan of PIR sandwich panels?
Typically 20–30 years, longer than EPS panels.
