ABSTRACT:
A double insulated, ventilating skylight for a building or the like, comprising inner and outer substantially co-extensive frames, each of the frames having at least one substantially rectangular vertical wall and an upwardly directed window panel, the vertical walls having substantially co-extensive openings therethrough. Inner and outer doors are hingeably mounted on the inner and outer frames respectively to close the openings or to provide ventilation therethrough. Means for opening and closing the inner door from within the building is provided, with linkage means connecting the outer door to the inner door so that both doors open and close simultaneously. For the purposes of insulation, means are provided for sealing the inner and outer doors against the inner and outer vertical walls when the doors are closed and insulation material substantially fills all spaces between the inner and outer frames, except where the insulation material would interfere with the ventilation or transmission of light through the window panels.
In an alternative embodiment, only the outer frame assembly and insulating material is provided, so that existing skylights may be doubly insulated as well. Linkage means are also provided for operably connecting the inner and outer doors, so that whatever means exist for operating the inner door, the outer door will be operated simultaneously therewith.
