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.
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.
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.
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
PIR insulation boards are also moisture-resistant because of their closed-cell structure. This prevents moisture absorption, ensuring effective insulation even during damp conditions.
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.
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.
Many manufacturers offer various customisation options to suit your needs. PIR panels can be customised based on the thickness, dimensions, or aesthetic appeal.
PIR panels find extensive applications in both internal uses as well as both external walls and roofs of the building.
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.
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.
Reputed manufacturers have their own team of engineers to help you install sandwich panels at the construction site, taking care of the transportation, quality check, proper assembly, and installation.
PIR sandwich panels from Rinac have been widely used across various industries. These state-of-the-art panels are equipped with unique properties to support different needs.
Rinac’s InstaCeil, PIR-insulated ceiling panels offer a superior alternative for conventional insulated and false ceilings with exceptional thermal and fire-resistant properties.
Additionally, Rianc’s clean modular construction (CMC) solutions offer improved strength and excellent thermal properties when combined with flat, leveled, corrugated surfaces inside out.
PIR panels have become a popular choice in the construction industry. With the speed of construction, easy installation, competitive pricing, exceptional thermal property, recyclability, and much more, the PIR panels also offer customization and flexibility.
