A straight duct is a linear section of rectangular or circular ducting used to transport air between HVAC components and spaces. It forms the main trunk or branch of ACMV systems and ensures consistent, efficient airflow.
Pre-insulated duct system features a rigid polyisocyanurate (PIR) insulation core, often with an embossed aluminum foil facing. This pre-insulated system is designed for internal use and offers benefits like low weight, quick installation, and space-saving possibilities.
