Insulated glass skylight assembly

An insulated glass skylight assembly adapted to be mounted to cover an opening in a roof structure, comprising:

• a box-like liner adapted to be mounted adjacent the edge of an opening in a roof structure areound the periphery thereof, to surround said opening and to form a wall extending upward from said roof structure;
• and
• a swinging window unit including,
• an insulated glass insert of a predetermined size and shape to substantially conform to said opening in said roof structure;
• an inner supporting frame adapted to engage and seat on said liner and to support said glass insert;
• an outer encasing frame adapted to be coupled to said inner supporting frame and capture said glass insert therebetween, said inner and outer frames being located adjacent said wall of said liner and engaging the peripheral portion of said glass insert so as to expose a maximum amount of said glass insert overlying the opening in said roof structure while maintaining minimum exterior dimensions for said skylight assembly;
• a first means for sealing positioned between said glass insert and said inner and outer frames to provide insulation and prevent a direct contact therebetween;
• a second means for sealing positioned between the engaging surfaces of said inner supporting frame and said liner so as to seal said engaging surfaces therebetween when said swinging window unit is positioned on said liner;
• and
• means for pivotably interconnecting said swinging window unit to said liner so as to permit shifting of said swinging window unit with respect to said liner between a closed position overlying said opening in said roof structure, said first means for sealing including a gasket interposed between said glass insert and said inner supporting frame, and a sealant system including a strip of sealing material disposed along the primeter of said glass insert and a strip of caulking disposed on said glass insert adjacent to said strip of sealing material on the side nearest to the center of said glass insert, said sealant system interposed between said outer encasing frame and said glass insert, said gasket has having a slot formed therein adapted to receive and seal the peripheral edge of said inner supporting frame and has having an outer orthogonally-projecting edge in position to cooperate in properly seating said glass insert and to prevent direct contact of said glass insert with said inner supporting frame and said outer encasing frame.

• a means for sealing positioned between said glass insert and said outer frame to provide insulation and prevent direct contact therebetween;
• and
• a unitary sealing means positioned between the engaging surfaces of said inner supporting frame and said liner and between the engaging surfaces of said glass insert and said inner supporting frame so as to seal engaging surfaces therebetween when said window unit is positioned on said liner.

An insulated glass skylight assembly adapted to be mounted to cover an opening in a roof structure, comprising:

• a box-like liner adapted to be mounted adjacent the edge of an opening in a roof structure around the periphery thereof, to surround said opening and to form a wall extending upward from said roof structure;
• and
• a swinging window unit including,
• an insulated glass insert of a predetermined size and shape to substantially conform to said opening in said roof structure;
• an inner liner supporting frame adapted to engage and seat on said liner and to support said glass insert;
• an outer encasing frame adapted to be coupled to said inner supporting frame and capture said glass insert therebetween, said inner and outer frames being located adjacent said wall of said liner and engaging the peripheral portion of said glass insert;
