OSTI ID:6493759
This patent describes a multiply glazed, vented window or door assembly comprising: spaced apart glass panes sealably secured perimetrally in parallel side sash members and parallel upper and lower sash members. At least one of the sash members has in its outer surface, a linear groove perimetrally aligned with the space between the panes and further having a breathing port extending from the marginal wall of the groove through to the space between the panes; an elongate flat plate having fine perforations and parallel end flanges projecting generally perpendicularly therefrom, fitting into and sealing off the groove at spaced distances from the port to provide an air circulation manifold under the plate. The plate is sufficiently long to have sufficient perforations to provide a cross-sectional area which correlates with the cross-sectional area of the port; and means for securing the plate in place.
