Abstract
Double paneled door assembly providing RF shielding and soundproofing through the use of two door panels, i.e., back door panel and front door panel, as well as respective back door frame and front door frame. The door panels and door frames are joined together by door pins and door pin bushing as well as frame pins and frame pin bushings, and the double door panels are mounted on the double frames by heavy duty hinges. The use of two door panels and frame panels with a volume of sealed air or other inert gas between the panels aids the RF shielding and soundproofing properties of the door. The bushings act as damping mechanisms to reduce transmission of vibration from the front side of the door assembly to the back side of the door assembly that will ultimately reduce waves permeating into an enclosed room or area.
