How is the PUR and PIR market changing in Europe? A technological and macroeconomic perspective

Just a dozen or so years ago, the choice of insulation technology was primarily a cost-driven decision. Today, manufacturers of insulated metal panels, investors, and designers must consider a much broader range of factors — from fire safety and energy efficiency to insurance requirements and expectations regarding the environmental footprint of a building project.

The development of the PUR and PIR market is also being increasingly influenced by wider macroeconomic trends, including rising energy costs, the growth of the logistics and warehousing sector, and the European Union’s climate policies. Interestingly, despite a common regulatory framework across Europe, the pace of change and the scale of the transition toward PIR systems still vary significantly from one country to another.

Why did Europe begin moving away from PUR?

Although PUR systems remained the standard in insulated panel production for many years, the European market gradually began to change its approach to insulation technologies used in industrial construction. This shift was driven primarily by increasingly stringent fire safety requirements and the growing importance of safety in industrial and warehouse facilities.

Over the past decade, Europe has experienced rapid growth in the logistics and warehousing sector. Larger high-bay warehouses, the expansion of e-commerce, and the increasing value of stored goods have made fire safety a much more significant consideration than in the past.

At the same time, both European and national regulations concerning the fire classification of construction materials and the fire resistance of building elements became more demanding. Particular importance was placed on requirements resulting from EN 13501-1+A1:2010, which significantly influenced the way industrial facilities are designed and assessed.

Investors and insurance companies also began playing a more influential role, focusing not only on construction costs but also on reducing fire risk and ensuring the long-term safety of entire facilities.

Europe is not developing uniformly

Although the European market operates under a common regulatory and construction framework, the pace of transition from PUR to PIR systems varies significantly between countries. Manufacturers’ and investors’ decisions are influenced not only by fire safety requirements but also by local economic conditions, industrial development, investment costs, and the specific characteristics of national construction markets.

In Western European countries such as Germany, Austria, Belgium, the Netherlands, and Switzerland, PIR systems quickly became the standard in modern industrial construction. These markets have long prioritized quality, long-term durability, and high fire safety standards. Trust in product quality and production consistency also plays a significant role. In practice, this translates into a greater willingness to invest in premium solutions and technologies that ensure highly repeatable performance.

A different situation can be observed in parts of Central and Eastern Europe. Romania is a good example, as it is currently one of the fastest-growing industrial construction markets in the region. At the same time, the country is becoming an increasingly attractive destination for foreign companies establishing manufacturing facilities and logistics centers in Central and Eastern Europe. For such investments, premium solutions that meet demanding requirements regarding quality, safety, and energy efficiency are chosen more frequently. As a result, the Romanian market is also rapidly advancing in terms of the technologies used in insulated panels.

At the same time, strong cost pressure remains a significant factor, and economical solutions continue to be widely used. Consequently, Romania represents an interesting example of a market positioned between a cost-driven approach and growing interest in premium technologies.

Differences are also visible between Northern and Southern Europe. In warmer regions such as Spain and Portugal, production economics continues to play a dominant role, whereas in colder climates thermal insulation performance and long-term energy efficiency are considerably more important.

As a result, the European PUR and PIR market is evolving along multiple paths. Despite common regulations, each country retains its own characteristics shaped by local economic conditions and the maturity of its investment environment.

The PUR and PIR market is entering a new stage of development

In many European countries, the market has already reached a certain level of maturity regarding the choice between PUR and PIR technologies. For modern industrial and logistics facilities, PIR systems have often become the standard due to fire safety requirements and investor expectations.

At the same time, panel manufacturers and investors increasingly expect more than compliance with basic insulation and fire performance criteria. Quality certifications and conformity with market-specific requirements across Europe are becoming increasingly important. In addition to international standards such as ISO, local certifications and requirements play a significant role, particularly in markets such as Germany, Switzerland, and Scandinavia, where special emphasis is placed on quality, performance consistency, and system safety.

For many manufacturers and investors, technical performance alone is no longer sufficient. Long-term quality consistency, supplier reliability, and the ability to meet additional requirements imposed by insurers and large international projects are becoming equally important.

The market is also paying increasing attention to sustainability, environmental performance, and the origin of raw materials used in PUR and PIR systems.

As a result, the European PUR and PIR market is gradually shifting away from basic price competition toward quality, safety, certification, and the long-term value of the overall solution.

Sustainability as a new direction for the PUR and PIR market

Sustainability has become one of the most important development drivers of the European construction industry, including the market for PUR and PIR systems used in insulated panel production. Increasingly, investors, manufacturers, and international industrial groups are evaluating not only the technical performance of a system but also its environmental impact.

The European Union plays a key role in this process. Through environmental regulations and climate policies, it is increasingly influencing the pace of change within the construction sector. This is particularly significant because the construction industry currently accounts for approximately 38% of global carbon dioxide emissions. In practice, this creates growing pressure to reduce the environmental footprint of buildings throughout their entire lifecycle—from raw material extraction and material production to building operation, demolition, and recycling.

As a result, interest is growing in solutions incorporating recycled raw materials, technologies that reduce carbon footprints, and systems that support ESG strategies. This trend is particularly visible in Western Europe, where energy efficiency, environmental performance, and ESG reporting increasingly influence purchasing decisions made by large organizations and international investors.

Importantly, as European regulations continue to evolve, non-financial reporting requirements will gradually extend to smaller companies. These businesses will increasingly expect suppliers to provide environmental data and greater transparency throughout the supply chain.

The approach of panel manufacturers is also changing. They are increasingly looking not only for stable and safe technologies but also for solutions that help create competitive advantages through sustainability and supply chain quality.

There are strong indications that environmental considerations will continue to play a growing role in the coming years, influencing not only PUR and PIR system manufacturers but also the entire European construction market and investment decisions at every stage of modern industrial and logistics projects.

The PUR and PIR market – Europe enters a new phase

The European PUR and PIR market is currently undergoing a period of significant transformation. Just over a decade ago, the choice of insulation technology was driven primarily by the economics of the system itself. Today, the market is increasingly focused on fire safety, energy efficiency, quality, certification, and the environmental impact of the overall solution.

Although the pace of change still differs from country to country, the direction of development across Europe is becoming increasingly clear. Modern PIR systems, premium solutions, and technologies that support long-term investment stability and safety are gaining greater importance.

At the same time, the construction industry is entering a new stage in which sustainability, supply chain transparency, and environmental responsibility are becoming just as important as technical performance.

As a result, the future of the PUR and PIR market will depend not only on technological advancements but also on the industry’s ability to respond to evolving regulatory, investment, and environmental requirements that are increasingly shaping modern industrial construction across Europe.

How to choose the right PIR System for real production needs in insulated panel manufacturing?

Puroxen 1800 vs 1750 — one market, different needs

Although PIR systems have become the industry standard in the production of metal-faced insulated panels, manufacturers are increasingly facing another important decision — selecting a system that best matches their production requirements and market expectations.

Today’s sandwich panel market is far more complex than it was just a few years ago. For some manufacturers, achieving the lowest possible thermal conductivity remains the key objective in order to produce panels with the highest insulation performance. Others focus primarily on process stability, a wide processing window, and the reliability of day-to-day production. An increasing number of producers are also paying close attention to production economics, line efficiency, and opportunities for cost optimization.

This is precisely why Purinova has developed different PIR systems designed to address specific market needs and various production models within the sandwich panel industry.

Two different approaches to PIR panel production

To meet the diverse needs of sandwich panel manufacturers, Purinova continues to develop a portfolio of PIR systems tailored to different production models and market expectations.

Puroxen 1800 was developed for manufacturers seeking the highest insulation performance, an exceptionally wide processing window, and maximum production stability. Puroxen 1750, on the other hand, addresses the needs of customers looking for the right balance between process stability, product performance, and production economics.

Although both systems belong to the group of advanced PIR technologies for insulated panel production, each was designed with different technological priorities and production approaches in mind.

Puroxen 1800 — a Premium-Class System

Puroxen 1800 is the most advanced PIR system in Purinova’s portfolio, developed for manufacturers seeking the highest insulation performance and maximum production process stability. The system was created in response to the needs of the most demanding customers, for whom not only laboratory results matter, but also production reliability, consistent quality, and the long-term stability of panel properties. It is primarily chosen by companies that build their competitive advantage on the quality of the finished product and the long-term trust of end users.

Puroxen 1800 is the result of many years of market experience and close cooperation with sandwich panel manufacturers. Its refined formulation combines very low thermal conductivity with high cell stability, excellent dimensional stability, and strong adhesion to metal facings.

One of the system’s greatest advantages is its wide processing window. In practice, this translates into greater day-to-day production stability and reduced risk of issues caused by fluctuations in ambient temperature, differences in operator performance, or temporary process deviations. This is why Puroxen 1800 is often selected by manufacturers seeking maximum process reliability and a lower risk of product claims.

The advanced performance of the system is primarily driven by Purinova’s formulation expertise. The careful selection of surfactants, catalysts, and additives influences not only the final panel properties but also the stability of the entire production process.

Foaming technology is another key factor in premium PIR systems. Puroxen 1800 has been developed to work with virtually all foaming technologies commonly used in the market — from conventional pentane-based blowing agents, such as n-pentane, cyclopentane, and cyclopentane/isopentane blends, to modern next-generation HFO (hydrofluoroolefin) blowing agents.

This compatibility with a wide range of blowing agents allows manufacturers to optimize the system according to the specific requirements of their production line and the desired panel performance. The choice of blowing agent affects not only the production process itself, but also the final thermal conductivity and long-term stability of the system.

Puroxen 1800 has been on the market for more than 10 years and has been proven in industrial use by numerous sandwich panel manufacturers. Thanks to its high process stability and consistent quality, the system is characterized by a very low level of customer claims compared with many solutions available on the market.

Puroxen 1750 — the balance between performance and production economics

Puroxen 1750 was developed in response to the needs of sandwich panel manufacturers seeking a stable and reliable PIR system while maintaining favorable production economics. The system was designed for customers who do not necessarily require the lowest possible thermal conductivity values, but instead focus on stable processing, efficient production, and consistent panel performance.

Puroxen 1750 was not created as a simplified version of a premium system, but rather as a solution tailored to a different production model and a different set of market requirements. In practice, this means a distinct formulation approach designed for production lines where the key objective is to combine process stability with cost optimization.

The system has been developed to deliver very good fire and mechanical performance while maintaining a wide and stable processing window. This allows manufacturers to sustain high production line efficiency while reducing the risk of technological issues during day-to-day operations.

Puroxen 1750 is particularly well suited to markets where not only the quality of the system itself matters, but also the overall economics of the production process and the ability to remain competitive while maintaining consistent finished product quality.

Solutions supporting sustainable development

Sustainability-related considerations are playing an increasingly important role in the construction industry. Investors and manufacturers are paying attention not only to the technical performance of finished products, but also to the origin of raw materials, the use of recycled content, and the environmental impact of products throughout their lifecycle.

In response to these market expectations, Purinova continues to expand its portfolio of solutions designed to support customers in achieving their sustainability goals. Alongside standard PIR systems, we develop technologies focused on increasing the share of recycled raw materials and reducing the use of selected chemical substances within formulations.

Particular emphasis is placed on solutions based on secondary raw materials. Purinova develops technologies that primarily utilize materials recovered from waste generated during the production and processing of PIR foams. The use of PIR dust as a raw material for new formulations allows valuable material to be reintroduced into the production cycle and represents a practical example of circular economy principles in action. Our sustainable product portfolio also includes formulations incorporating recycled PET-based raw materials, which have long been recognized and utilized within the polyurethane industry.

Purinova’s portfolio also includes halogen-free systems. This means that the formulations do not contain halogenated flame-retardant additives used in some traditional solutions. Such an approach is increasingly recognized as one of the key directions in the development of modern insulation materials, responding to growing market expectations related to sustainability, product stewardship, and future environmental regulations.

Importantly, modern sustainable solutions are no longer merely a complementary offering. Thanks to carefully engineered formulations, they can deliver performance comparable to traditional systems based on petrochemical raw materials, while maintaining excellent thermal insulation properties, mechanical performance, and processing stability. This allows sandwich panel manufacturers to pursue their sustainability objectives without compromising the quality, process reliability, and production efficiency expected from modern PIR systems.

Technological support as part of the System

In modern sandwich panel manufacturing, the PIR system itself is often only one part of the overall technological process. Equally important today is the know-how behind the formulation, quality consistency, and day-to-day production support.

Panel manufacturers know their production lines, capabilities, and limitations better than anyone. Purinova’s role is to understand the chemistry of the entire process and support customers in achieving stable, safe, and repeatable production. Every production line operates under different conditions — varying in length, speed, equipment configuration, and process characteristics — which is why implementing a PIR system often requires an individual technological approach.

Technical support extends far beyond the initial start-up phase. It also includes further process optimization, sample analysis, and ongoing quality monitoring. An equally important aspect is the selection of the right formulation, catalyst packages, and processing parameters tailored to a specific production line.

Another key element of technical support is ensuring the consistency of the supplied system. Even the most optimized production process can become problematic if raw material properties vary from one delivery to another. For panel manufacturers, consistency of system parameters has a direct impact on product quality, process repeatability, and overall production efficiency.

Maintaining this consistency is supported by an extensive laboratory infrastructure and a multi-stage quality control process covering both raw materials and system components used in PIR production. Supplier qualification, raw material verification, and continuous monitoring of production processes help minimize the risk of unwanted deviations and ensure customers receive a stable and reliable product.

In practice, this means that a modern PIR system is much more than just a chemical formulation. It is also a guarantee of consistent quality, technical support, and expertise that helps customers achieve reliable day-to-day production.

One market – multiple strategies

Today’s insulated panel market clearly demonstrates that selecting the right PIR system is about much more than simply comparing technical parameters. Equally important are the characteristics of the production line, the desired process efficiency, the performance requirements of the finished panels, and the manufacturer’s long-term business objectives.

Puroxen 1800 and Puroxen 1750 were developed with different production priorities in mind. The former focuses on achieving the highest insulation performance and maximum process stability, while the latter offers an attractive balance between production efficiency, processing stability, and manufacturing economics.

Regardless of the system selected, success depends not only on the formulation itself, but also on technical support, quality consistency, and the ability to tailor the solution to individual production conditions. It is the combination of these factors that enables manufacturers to achieve stable, reliable, and competitive insulated panel production.
