<p>A double glazing unit comprising separator frame members surrounding a dead air insulating space between panes of glass. The frame members are located inwardly of the edges of the panes to form a channel defined by outer faces of the frame members and the surfaces of the panes from the frame members to the edges of the panes. A sealing substance is disposed to fill the channel. The improvement resides wherein the frame members have a cross-section providing central side portions in direct engagement with the surfaces of the panes to minimize or eliminate any passage of air and moisture to or from the dead space and surfaces sloping away from the panes to form, with the panes, recesses open to the dead air space inwardly of the central portions. Adhesive is disposed substantially to fill the recesses inwardly of the central portions and to adhere to the surfaces of the panes and to the surfaces of the frame members.</p> |
