Patent ID: 7117640

Claim:
A RF shielded and acoustically insulated room door panel, the door panel comprising: a first outer section; a second outer section; a first side member extending along a side edge of the first outer section; a second side member extending along an opposite side edge of the first outer section; said first and second side members having inner surfaces facing each other and outer surfaces facing opposing directions, said outer surfaces facing away from the first outer section; an acoustic noise absorbing layer disposed between the first outer section and the second outer section; and a RF shielding layer disposed between the first outer section and the second outer section, wherein the RF shielding layer is positioned adjacent to and spaced apart from one of the first outer section and the second outer section thereby defining an acoustic noise insulating air gap free of insulation between the RF shielding layer and one of the first outer section and the second outer section, said RF shielding layer extending to the outer surfaces of the first and second side members.
