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.

PIR 和酚醛绝缘材料有什么区别？在选择绝缘材料时，PIR 和酚醛绝缘板是最佳选择。虽然酚醛板以其出色的热性能而闻名，但 PIR 绝缘板在几个关键方面往往表现优于酚醛板。下面，我们重点介绍这两者之间的主要区别 […]

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.
