PIR stands for polyisocyanurate, and this is one of the most commonly used materials for building PIR Sandwich panels. The PIR panels are an improved version of PUR (polyurethane) panels. These kinds of panels are majorly used for constructing industrial walls and ceilings, their biggest advantage being fire resistance and structural strength they offer. PIR panels have a Polyisocyanurate core with highly crosslinked polymers, and this makes these closed-cell foam panels the best for thermo-insulation, extra tensile strength while also being quite lightweight.

This effective thermal insulation also ensures the least negligence in thermal conductivity. These features thus also additionally make the PIR panels ideal to be used in cold storage, humidity areas and refrigerators. The enclosing sheets are usually made of Aluminium, plywoods, coated or stainless steel, FRP or flexible boards. 

These PIR panels are designed with the typical tongue and groove style, sometimes with a metal cam locking system to secure joints against air leakage. The insulation performance and fire resistance are not the only advantages of this kind of panel, as they have excellent acoustic applications making them preferable for buildings. The cost and performance may vary based on which material is used. But it offers even better thermal stability and flammability resistance than polyurethane foam.


To sum up, PIR panels are typically used for roof panelling, warehouse walls and ceilings, clean and cold rooms, air handling units, wall panelling for Condominium, panelling modular houses. However, PIR panelling cannot be used as insulation for existing cavity walls, as PIR foams cannot be inserted within existing cavity walls. 


Another advantage of this panelling is that they are eco-friendly and reusable, saving heat and a further charge for maintenance, thus making it a great choice for air conditioning units. As we have mentioned before fire resistance is one of the key advantages of PIR panels which makes it one of the best choices for safety purposes. These panels are easy to clean compared to other similar panels made of other materials, so it’s a great choice for building industrial walls and ceilings where dirt accumulation happens at a higher rate.

Furthermore, these panels are built in a modular style, which ensures that they can be assembled and installed easily. Similarly, these panels can be disassembled just as easily, thus making portability one of the advantages of using PIR panels. The corner panels are built at a 90-degree angle which offers extra strength and stability. 

Customisation is another great advantage of using PIR panels, as it is available in a varied range of colours and textures. The customisation also ensures that these panels can easily be fitted effectively into every wall, roof, floors and doors. These customisations also make these PIR panels quite budget-friendly. What’s more along with being excellent acoustic feedback it can also be made soundproof and is impervious to moisture absorption.

The moisture repelling feature along with complete water and vapour resistance property is a huge advantage, as this gives the panel antibacterial properties. This makes PIR panels suitable for certain industries like pharmaceutical storages.
