Although the processability between PIR and PUR panels is similar but with certain differentiating nuances, such as processing temperatures, higher in the case of PIR panels, or the use of adhesives to improve the adhesion between the sheet and the foam, in the case of PIR panels, although more and more PUR panels producers are also using an adhesive in certain panels to guarantee the adhesion between the sheet and the foam, the field of application of PUR/ PIR sandwich panels is very similar, and they can be used for:
- External enclosure: facades and roofs.
- Compartmentalisation of interior spaces: fire sectors, partitions, food processing rooms, clean rooms, cold rooms, etc...
Advantages of PUR/PIR sandwich panels
The advantages of PUR / PIR sandwich panels is what makes these insulation panels even more attractive for health, safety and environment:
- Thermal insulation: It is one of the thermal insulation products with the lowest thermal conductivity coefficient. It guarantees the absence of thermal bridges thanks to the homogeneity of the insulation at all points of the panel. The assembly also minimises thermal bridges thanks to the joints, normally tongue and groove, between panels. Reduced insulation thickness thanks to the low thermal conductivity coefficient of the polyurethane foam.
- Optimisation of usable space, since a minimum thickness is required to achieve a maximum thermal insulation level.
- Virtually no water absorption due to the closed cell structure of the polymer, which makes them waterproof.
- Mechanical properties that give the panels great rigidity and low weight, which facilitates and economises transport, handling, installation and structural sizing. Ease of machining and cutting.
- Reaction to fire performance which makes PUR/PIR sandwich panels fire safe.
- PUR/PIR sandwich panels are a prefabricated product, sustainable in their manufacture and very light for transport to the construction site. The construction of a building, both residential and industrial, with polyurethane sandwich panels generates very little waste which makes the building process more sustainable. It is recyclable: the metal sheet is melted and the polyurethane is recycled using three techniques; mechanical recycling, chemical recycling or incineration with energy recovery. The insulating capacity of polyurethane sandwich panels helps to reduce energy consumption.
Properties of PUR/PIR sandwich panels
In terms of properties, the main difference between PUR/PIR sandwich panels lies in their composition. The foam obtained with PIR (Polyisocyanurate) systems contains a high degree of aromaticity due to the formation of the polyisocyanurate structure, providing a higher thermal stability compared to urethane (PUR) groups, thus improving its fire resistance.
The PIR foam reacts safely to fire by forming a carbonised surface layer that protects and prevents the penetration of fire into the inner layers. In the composition of PIR panels, as a general rule, there is a lower concentration of flame retardants than in PUR panels, thus generating less smoke during combustion. There are even PIR panels on the market that are free of halogen flame retardants.
Even so, the products must be tested to determine their fire behaviour with the reaction and fire resistance test methods according to current regulations depending on the location.
In terms of thermal properties, PIR remains stable in a higher temperature range than PUR.

What are PUR and PIR boards?
PUR and PIR boards are high-tech insulation materials that are widely used in the construction industry. PUR (polyurethane) board is a traditional insulation material made from polyurethane, which is lightweight, durable and effective in protecting buildings from heat loss. It is primarily used for insulating roofs, walls, as well as attics and foundations. PIR (polyisocyanurate) board , on the other hand, is a more advanced version of polyurethane that contains more isocyanurate rings, making it more resistant to high temperatures and fire. PIR is often used where greater resistance to external conditions is required, for example in industrial construction.

Main differences between PIR and PUR boards
One of the key differences between the two materials is their chemical composition. PIR panels have better fire resistance due to the additional isocyanurate rings, making them more suitable for areas where the risk of fire is higher. PUR panels, on the other hand, have greater flexibility, which can be an advantage in applications where the material needs to conform to irregular shapes.
Temperature resistance is another important aspect that distinguishes the two materials. PIR boards have a much better resistance to high temperatures, making them more versatile and safer for industrial applications or buildings with a higher risk of fire. For this reason, PIR panels are often chosen for insulating flat roofs, external walls or warehouses.
In terms of thermal insulation, both materials offer excellent performance, but PIR boards have a slightly better thermal conductivity coefficient than PUR boards. This means that for the same thickness, PIR boards provide better thermal insulation. For projects where maximum energy savings are a priority, the choice of PIR panels may be more beneficial.
One of the more practical differences is the price. PUR boards tend to be cheaper than PIR boards, making them a more common choice for residential buildings where fire safety issues are not as critical. PIR panels are more expensive, but their higher price is justified by their better thermal properties and higher resistance to external factors.
Application of PUR and PIR boards
The differences between PUR and PIR boards affect their application. PUR boards are ideal for insulating roofs, attics and walls in residential buildings. Due to their flexibility, they work well in irregularly shaped areas where the material needs to fill the space precisely. In addition, the lower cost makes them more affordable for private investors who are looking for efficient but cost-effective solutions.
PIR boards, on the other hand, are better suited to more demanding conditions, such as insulating industrial or commercial buildings. Thanks to their higher fire resistance and better insulating performance, they are often used in facilities where special protection against high temperatures is required. PIR is also more commonly chosen for insulating flat roofs, where there is a greater risk of surface heating.
Which solution to choose?
The decision to choose PIR or PUR panels depends primarily on the specifics of the project in question and the insulation expectations. PIR board will be a better choice where fire safety and maximum thermal efficiency are priorities. PUR board, on the other hand, will prove its worth where flexibility, affordability and versatility of use are more important.
In residential buildings, where there is not a high risk of fire and the flexibility of the material is key, PUR board may be the ideal solution. In industrial or commercial buildings, where increased fire protection is required, PIR panels will be a better choice.
