  • Ceiling module perimeter seal
    Patent number: 6351920
    Abstract: A ceiling module perimeter seal establishes an air-tight seal between modules forming a ceiling structure. The seal includes a groove about the perimeter of modules and aligned relative to a corresponding groove of an adjoining module. Aligned grooves in adjacent ceiling modules establish an enclosure between modules and apertures fluidly couple the enclosure with gel sealant troughs of the ceiling structure. Gel sealant flowing in the troughs enters the enclosure and thereby establishes an air tight seal between adjoining ceiling modules.
