ABSTRACT:
A contaminant sealing system which may be utilized to enclose dust and other contaminants such as asbestos in an area between the roof and ceiling of a building. The contaminant sealing system utilizes a new and novel suspended ceiling comprising a plurality of ceiling tile frames, and a plurality of ceiling tiles which are positioned within the ceiling tile frames by way of an attaching mating means such that the cell which is formed is sealed to prevent the passing of dust or other contaminants through the cells. The plurality of cells are connected to each other and sealing means are provided in the form of seam covers to prevent dust or contaminants from passing through the connection between the cells. A plurality of X-shaped braces are positioned partially over the seam covers and are fixedly attached to the corners of the ceiling tile frames to reinforce the entire structure. Hanging means are provided for hanging the ceiling structure to an existing overhead ceiling joist, thereby providing a suspended ceiling which encloses dust or other contaminants from the remainder of the room. Also disclosed is a modification of the contaminant sealing system which utilizes a metal hood which is attached to the top portion of the plurality of ceiling tiles and each metal hood thereby prevents the passing of radio waves or the like through the ceiling and into the room. Also disclosed is a new and novel method for sealing dust and contaminants and enclosing the dust and contaminants within an area between the roof and ceiling of a building.
