An In-Depth Guide to PIR Panels: Understanding Their Use ...

The modern construction industry is witnessing an increased demand for sustainable and energy-efficient building materials. One such innovative construction material is polyisocyanurate or PIR panels which offer clear benefits over other traditional materials such as polyurethane (PUR). Undoubtedly, any building, whether commercial or residential, requires excellent insulation to save on energy bills and improve the comfort of the people, especially during cold seasons. This is where PIR panels have proven their worth.

In this article, we will discuss more about PIR panels, their benefits, uses, and much more. 

What Are PIR Panels?

PIR is a thermoset polymeric material that combines isocyanates and polyols. PIR panels are rigid insulation boards that are made of polyisocyanurate foam. The panels comprise PIR foam that is sandwiched between two surfaces, preferably metals. The manufacturing process of the PIR foam results in a highly cross-linked, closed-cell structure/ This ensures very low thermal conductivity and, thus, exceptional thermal insulation and performance. 

Additionally, being a thermoset plastic, PIR is a rigid, robust material and does not melt when heated. On the other hand, thermoplastic materials such as polyethylene or polystyrene soften to turn into a liquid when heated. 

These PIR panels can also come faced with aluminium foil to create a barrier against moisture and improve performance against flames. Thus, depending on the manufacturer, PIR panels can also be fire-resistant. 

What Are the Benefits of Using PIR Panels

PIR panels are the most widely used cladding system for roofs and walls as well as internally for walls, ceilings, linings, and partitions. Let&#;s discuss some of the unique benefits and properties of PIR panels that make them a preferred choice in the construction industry. 

Exceptional thermal performance

PIR panels have excellent thermal insulation properties, minimizing heat transfer and thus maintaining the desired temperature. This means a reduced need for heating and cooling systems as well as energy savings. 

Lightweight and Easy installation 

PIR panels are relatively lightweight and, therefore, easy to transport and install. Their lightweight also makes them a preferred construction material when it comes to reducing the structural load on the building. 

Also, they are easy to disassemble and hence offer the 

Barrier against moisture 

 PIR insulation boards are also moisture-resistant because of their closed-cell structure. This prevents moisture absorption, ensuring effective insulation even during damp conditions. 

Better fire properties 

PIR foam, due to the presence of isocyanurate rings, shows comparatively better fire properties than PUR. Experts have also stated that usually, PIR panels do not increase the risk of the spread of fire or influence the fire severity. However, the fire rating depends on the manufacturer. 

Strength and durability 

PIR panels have a high compressive strength that improves their durability and service life (longevity). Be it high footfall or harsh weather conditions such as temperature fluctuations, rain, and wind, PIR panels are designed to withstand unsuitable environmental conditions. 

Design flexibility 

Many manufacturers offer various customisation options to suit your needs. PIR panels can be customised based on the thickness, dimensions, or aesthetic appeal. 

What Are Different Applications of PIR Panels? 

PIR panels find extensive applications in both internal uses as well as both external walls and roofs of the building. 

• Clean rooms

• Cold rooms, storage, and warehouses 

• Air handling units (AHU)

• Roof panels 

• Wall panels 

• Lining panels within existing buildings 

• Separation walls (usually fire-resistant) between the sections of a building 

• Panels in modular/prefabricated buildings 

• Factories and industrial premises 

• Hospitals and their extensions, and clinics

• Schools and universities 

• Leisure such as cinema halls and others 

Points to Consider During Installation 

There have been misconceptions about how the performance of insulation products is affected by their design and installation, especially when they are part of ground-floor build-ups. 

Here are a few points. For instance, 

A PIR insulation board should be placed above the DPM (damp-proof membrane) for protection against moisture. 

• It should also be placed below the AVCL (air and vapor control layer to reduce any potential risk of condensation from the floor and also to protect the foil facing from alkalis in screed over it. 

Without correct installation, there is always an associated risk. The performance of PIR insulated panels can be compromised due to moisture or damage to the foil facing.

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.

Panels in action

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.
