PIR Sandwich Panel

Polyisocyanurate or PIR is a fireproof insulation material, derived from polyurethane. The PIR sandwich panels are manufactured on the continuous lines and the space between the metal sheets is filled with fireproof polyisocyanurate foam.This process makes the insulating layer of sandwich panels homogeneous and improves PIR panels’ strength and thermal properties in comparison with EPS-core panels.

What is the difference between PIR and PU sandwich panels?

In summary, while both PUR and PIR are effective insulation materials, PIR offers better insulation performance, improved fire resistance, and enhanced moisture resistance compared to PUR. However, the choice between the two will depend on factors such as project requirements, budget, and specific application needs.
