A panel that emits infrared light is known as an PIR panel. A heat source, such as a halogen lamp, is housed inside the panel, which is constructed out of an IR-transmissive material like glass or plastic. Infrared radiation is produced by the heat source and subsequently released from the panel. Polyisocyanurate (PIR), which is usually cut into boards, can be used as insulated plasterboard, in wall cavities, and in insulated metal panels. PIR panel requires only half the thickness of other mineral-based insulation because of its superior thermal performance. It is well known for usage as a low-moisture barrier, similar to PUR.
