Hollow core door with perimeter air flow

A hollow core door having a panel about which air flows to prevent pressure build up in a room having a forced air system for providing a flow of air into the room comprising in combination:

• a pair of stiles spaced apart;
• a pair of rails spaced apart and secured to the spaced apart pair of stiles to define a frame;
• an inside skin secured to the frame;
• an opening in the inside skin having an inner periphery of a first length;
• an outside skin secured to the frame;
• an opening in the outside skin having an inner periphery of a second length which is substantially the same length as the first length of the opening in the inside skin;
• a panel secured to and spaced apart from and disposed between the inside and outside skins, and having an outer periphery which is greater in length than the first length of the opening in the inside skin, which first length is substantially the same length as the second length of the outside skin inner peripheries of the openings in the inside and outside skins, whereby air flows non-linearly with at least five changes of direction in the air flow through the opening in the inside skin, about the outer periphery of the panel, and outwardly through the opening in the outside skin.
