PIR HVAC Ductwork Panels: A Comprehensive Guide for Contractors
As a contractor, selecting the right ductwork material is crucial for ensuring energy efficiency, fire safety, and long-term performance in HVAC systems. PIR (Polyisocyanurate) pre-insulated ductwork panels offer a superior solution compared to traditional materials like mineral wool or phenolic foam. Below is a detailed introduction to help you understand their benefits, specifications, and installation advantages.
1. What Are PIR HVAC Ductwork Panels?
PIR ductwork panels consist of a rigid PIR foam core sandwiched between two protective layers, typically:
Inner & Outer Layers: Aluminum foil (0.08–0.2mm), for durability and moisture resistance.
Core Material: PIR foam, a modified polyurethane with enhanced fire resistance and thermal efficiency.
