The Pre-Insulated (PIR) duct industry in Sri Lanka has generated significant attention recently, with plenty of noise around various misconceptions. In this article, Kingspan, a global leader in the PIR duct industry, aims to clear the air and provide accurate information about PIR ducts and their benefits. PIR ducts are insulated systems made from polyisocyanurate foam, known for their high thermal efficiency, lightweight design, and strong corrosion resistance. Despite these qualities, Sri Lanka’s initial exposure to lower-quality brands has unfortunately created a negative impression.

When comparing PIR ducts with the more traditional Galvanised Iron (GI) ducts, the benefits of GI ducts come at a price. GI ducts are robust, capable of withstanding physical stress, and resistant to impacts.

However, they are also heavy, leading to increased labour costs and difficulty during installation. Their rigidity limits design flexibility, often resulting in costly modifications.

Furthermore, GI ducts are susceptible to corrosion in humid environments, significantly reducing their lifespan and requiring higher maintenance.

On the other hand, PIR ducts are lighter—15 to 20% less than GI ducts—which reduces installation time and labour costs. Their flexibility allows for easy adjustments during installation, making them suitable for a range of projects. PIR ducts are also corrosion-resistant, which minimises maintenance and extends their lifespan regardless of the environment.

Additionally, PIR ducts offer natural acoustic and thermal insulation, making them a more energy-efficient choice. Their sleek, aesthetically pleasing finish only adds to their appeal in modern applications.

The PIR industry has also faced challenges with unethical practices, as evidenced by a recent incident involving a well-known brand manipulating product certifications and test reports to gain approval for high-value projects.

However, while some brands may resort to such tactics, others are committed to manufacturing high-quality, sustainable products that adhere to proper standards. Choosing the right brand for specific project needs is key to reaping the true benefits of PIR ducts.

When selecting the right PIR brand it is essential to review the type, weight, and composition of the product, request samples for inspection, and insist on genuine fire, toxicity, and smoke certificates that meet global standards. Visiting the manufacturer’s factory, understanding the production process, and confirming the availability of stock are also crucial. Ensuring that panels and accessories come from the same brand is vital for maintaining uniformity and quality.
