When constructing energy-efficient production facilities, warehouses, or residential buildings, choosing the right insulation is crucial. Two common types of rigid insulation used in insulation panels are Polyisocyanurate (PIR) panel and Expanded Polystyrene (EPS) panel. While they may seem similar, they have distinct characteristics that make them suitable for different applications. Technology Polyisocyanurate (PIR): PIR panel […]

PIR insulation boards are rigid foam panels made from polyisocyanurate, offering excellent thermal performance, moisture resistance, and durability. Commonly used in walls, floors, and roofs, PIR boards feature low-emissivity foil facings that enhance insulation and act as vapor barriers. With a low thermal conductivity (as low as 0.022 W/m·K), they are ideal for modern construction standards requiring space-efficient and energy-efficient solutions.

Quelle est la différence entre le PIR et l'isolation phénolique ? Lorsqu’il s’agit de choisir des matériaux d’isolation, les panneaux isolants PIR et phénoliques font partie des meilleures options disponibles. Alors que les panneaux phénoliques sont connus pour leurs excellentes propriétés thermiques, les panneaux isolants PIR les surpassent souvent sur plusieurs aspects clés. Ci-dessous, nous soulignons les principales différences entre ces deux […]

Pre-insulated duct board materials are an advanced alternative to traditional metal ductwork in HVAC systems, offering lower thermal conductivity, improved fire performance, lighter weight, and faster installation. Common options include phenolic, PU, and PIR duct boards, each providing distinct advantages in thermal insulation, durability, and safety. By reducing heat loss, preventing condensation, and improving airtightness, pre-insulated duct boards help lower energy consumption and enhance overall HVAC system efficiency, making them a reliable and cost-effective solution for modern building applications.

Pre-insulated ducts made from PU, PIR, or phenolic foam offer superior thermal insulation, lightweight construction, moisture resistance, and low noise compared to traditional galvanized iron (GI) ducts. They eliminate the need for additional insulation layers, simplify installation, and reduce long-term energy costs. Ideal for projects with space or weight constraints, pre-insulated duct systems can achieve over 20% energy savings over a 30-year lifespan.

This guide provides a step-by-step overview of installing PIR, PU, and Phenolic pre-insulated air ducts—from tracing and cutting to folding, taping, reinforcement, and final sealing. Proper installation ensures airtight performance, better airflow, and long-term HVAC efficiency.
