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 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 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.

Why use insulated panels?

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.

  • One piece factory engineered product – simplicity of construction
  • Speed of construction – quicker amortisation
  • Factory installed quality – guaranteed performance
  • Competitive cost – performance with minimum risk
  • Flexible specifications – readily meets performance specifications
  • Highest inbuilt thermal performance – minimum thickness: lowest weight
  • Engineered joints – highest inbuilt air tightness
  • Factory engineered – proven fire performance
  • Proven designs – quality and appearance
  • Totally engineered system – proven buildability
  • Refurbishment – the economic solution

Panels in action

From the more traditional ‘big sheds’ to public buildings and architectural statements, insulated panel systems are also increasingly used on domestic 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.


High levels of insulation and airtightness contribute to a more comfortable working environment, whilst the range of colours and finishes available adds interest to the surroundings.

Industrial and warehouse

Strong, lightweight insulated panel systems help to reduce the need for secondary steelwork in large industrial buildings.

Public sector: education

Insulated panels are often used to upgrade educational buildings, or to build energy efficient new ones.

Public sector: healthcare

Good levels of fire and thermal performance and fibre free construction make insulated panel systems a good choice for clean environments such as hospitals and healthcare buildings.


Insulated panel systems can provide a thermally efficient substrate for traditional finishes such as tiled roofs, or the systems themselves can be used for a modern look.


Insulated panel systems combine high levels of thermal performance with attractive profiles and colour options. Speed of construction means that business can be up and running more quickly.

Sports & leisure

From studios to theatres, stands to stadia, insulated panels can be found in many sport and leisure venues.


Airports, service stations, car parks all make use of the benefits of insulated panels for speed, style and performance.

Controlled environments

Whether it’s a medical facility or a warehouse storing perishable goods, EPIC-member panels offer excellent thermal efficiency and airtightness which, coupled with their proven fire performance, makes them a great choice for creating cold storage or any environment where the air quality and temperature need to be tightly controlled.
