PIR (polyisocyanurate) metal-faced insulated panels are one of the most versatile forms of lightweight construction, combining design flexibility with high performance and factory in-built quality. They are also the most widely used cladding system for the roofs and walls, being used on 60% of all modern industrial and commercial buildings.

In addition to traditional industrial and warehouse projects, panels are now regularly specified for buildings in the retail, distribution, leisure, commercial, chill and cold stores, transport and energy sectors, as well as for hospitals, schools and accommodation. PIR cored panels are used as roofs and walls for the external envelope and also internally for walls, ceilings, partitions and linings. The unique advantages of insulated panels make them a valuable resource to create buildings that are both aesthetically pleasing and offer guaranteed in-service performance.
Ease of installation, relative light weight and energy saving features resulting in accelerated payback are the principle reasons why insulated panels are one of the main products used in the refurbishment of existing buildings, helping to bring them up to current energy and airtightness standards.
The unique advantages of Insulated Panels are what make them such a valuable resource to create buildings that are both aesthetically pleasing and offer guaranteed in-service performance.
From the more traditional ‘big sheds’ to public buildings and architectural statements, insulated panel systems are also increasingly used on residential buildings. In every case the same benefits of clean, fast track construction, excellent thermal performance and durability apply. As well as these performance benefits, insulated panel systems have evolved to provide a focal point in terms of design. They are no longer available in just the familiar trapezoidal profile widely associated with industrial style buildings; a range of different profiles now add interest, including curved, flat or micro rib, and specifiers can also make use of a vast array of colours to distinguish their designs from the ordinary.
Insulated panels can be used as a high performing substrate for facades or roofs using almost any kind of construction material, from traditional slate or tiles to glass, metal, wood or ceramic, opening up the design possibilities even further. There are not just aesthetic advantages to be found in the use of insulated panels; their strength makes them able to support green roofs, and also to accommodate renewable technologies such as photovoltaics, adding greatly to the potential of projects to enhance sustainability.

What is PIR Insulation?
Polyisocyanurate (PIR) insulation, a type of foam board, is well known for its superior thermal insulation capabilities. The production of PIR involves a chemical reaction between a polyol and an isocyanate, creating a rigid foam. This foam stands out for its high thermal resistance, low water absorption, and impressive structural strength. The distinctive fine cell structure and closed-cell composition of PIR contribute to its exceptional thermal performance and resistance to moisture.
Why is PIR Insulation so Expensive?
PIR insulation's notable performance comes with a higher price tag compared to alternatives. Several factors contribute to this cost disparity:
Despite its higher initial expense, PIR insulation's benefits - superior thermal performance, durability, and fire resistance - justify its cost, offering long-term savings and performance advantages.

UK PIR Insulation comparison chart
There's a PIR board for virtually every part of your building envelope, from stud walls and floors to roofs and lofts.
This chart provides a detailed comparison of various PIR insulation boards available in the market from brands like Xtratherm, Celotex, Recticel, Kingspan, Ecotherm, and IKO. From their thermal properties to compressive strength, and from their versatility in application to their dimensions, we've gathered data from leading manufacturers to help you make an informed decision.
Comparing PIR to Other Insulation Board Types
When it comes to insulation, one size does not fit all. Each type of insulation board offers unique benefits and limitations, making the choice highly dependent on specific project requirements.
PIR vs EPS Insulation

So, which is better, EPS or PIR?
The lower the R-value, the better the insulation! PIR may be more expensive to buy, it outperforms EPS in all other aspects.
PIR vs HP+
So, which is better, PIR or HP+?
Ultimately, for projects prioritising space and efficiency, PIR is the superior choice. However, HP+ is a strong contender for those seeking a balance between cost, performance, and flexibility in installation thickness. Both materials offer significant potential for energy cost savings, with the decision often boiling down to the specific application and project requirements.
PIR vs XPS
So, which is better, PIR or XPS?
XPS and PIR are closely matched in terms of moisture resistance and compressive strength, but PIR edges ahead with its thermal performance and fire safety ratings. For projects where thermal efficiency is paramount, PIR stands out as the more effective solution.
PIR vs Phenolic
So, which is better, PIR or Phenolic Insulation?
Phenolic foam offers excellent fire performance and a slightly better thermal efficiency than PIR. However, its higher cost, susceptibility to moisture, and more complex installation process can make PIR a more practical choice for a wide range of applications.
Is PIR insulation right for me?
Choosing the right insulation material is a crucial decision in any construction or renovation project. As we've explored, PIR insulation stands out for its exceptional balance of thermal efficiency, fire safety, and versatility across different applications. While other materials like EPS, HP+, XPS, and phenolic foam have their respective strengths, PIR often emerges as the best overall choice for homeowners and builders looking to enhance energy efficiency and reduce long-term costs.
The comparison highlights the importance of considering not just upfront costs but also long-term savings and performance benefits. Ultimately, the "winner" in the insulation race will depend on specific project requirements, but PIR insulation is undoubtedly a top contender for those seeking to maximise energy efficiency and building performance.
FAQs
Can PIR insulation be used in all areas of a building?
Yes, PIR insulation is versatile and can be used in various parts of a building, including roofs, walls, and floors. Its excellent thermal efficiency and moisture resistance make it suitable for both interior and exterior applications.
How does PIR insulation compare to fiberglass insulation in terms of R-value?
PIR insulation typically offers a higher R-value per inch than fiberglass insulation, meaning it provides greater thermal resistance and thus better insulation in a thinner layer. This makes PIR an efficient choice for areas where space is limited.
Is PIR insulation environmentally friendly?
While PIR insulation involves chemicals in its production, many manufacturers are moving towards more environmentally friendly blowing agents and materials. Its high efficiency also means that buildings require less energy for heating and cooling, contributing to overall energy savings.
Can PIR insulation be recycled?
Recycling PIR insulation can be challenging due to its chemical composition and the blowing agents used. However, efforts are being made to improve recyclability and manage end-of-life disposal in an eco-friendly manner.
How long does PIR insulation last?
PIR insulation is known for its durability and can last the lifespan of a building if properly installed and protected from UV light and physical damage. Its resistance to moisture and mould contributes to its longevity.
Does PIR insulation need a vapor barrier?
Due to its closed-cell structure, PIR insulation inherently resists moisture absorption, reducing the need for an additional vapor barrier in many applications. However, building codes and specific project requirements should always be consulted.
Is PIR insulation fire resistant?
PIR insulation has better fire resistance compared to other foam-based insulations like EPS or XPS. It is treated with fire retardant chemicals, which improve its fire performance. Nonetheless, it's important to comply with all applicable building codes and standards regarding fire safety.
How does PIR insulation handle moisture and water exposure?
Thanks to its closed-cell structure, PIR insulation is less prone to water absorption, making it an excellent choice for damp or prone-to-flooding areas. However, prolonged exposure to water should be avoided to maintain its insulating properties.
