ImperiClad Door Jamb and System

Keep the weather out and protect against moisture with Quanex’s ImperiClad™ Composite Door System, featuring an integrated door jamb and threshold system. Made from Quanex’s MikronWood™ engineered composite material, ImperiClad systems are energy-efficient and outperform competitive materials.
