PIRMAX Ductboard

High Thermal Performance Insulation Ductboard for HVAC Applications

Product Introduction

PIRMAX DUCTBOARD is a modified PIR (Polyisocyanurate) rigid thermal panel that can be used in domestic and commercial ducting. The PIR is laminated with non permeable aluminium foil to both sides of the board with one side black.

PIRMAX DUCTBOARD is extremely lightweight, easy to handle, allowing faster installs in HVAC ductwork applications and requiring less support hangers. With closed cell content greater than 90% and very low water transmission, even through the core, PIRMAX DUCTBOARD is highly resistant to moisture penetration.
