A radius elbow is a curved duct fitting designed to redirect airflow at various angles (typically 45° or 90°) with minimal resistance and pressure loss. Its smooth curvature ensures efficient airflow transition and reduces turbulence.
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.
