Abstract
A multiple glass sheet insulating unit having a welded or fused glass, sealed peripheral edge. The unit comprises at least two glass sheets each having a low emissivity coating applied to a surface thereof. The sheets are disposed such that the hermetically sealed space between the sheets is of a width between 0.125 inch to 0.375 inch and the coating on one of the sheets faces the sealed space and the coating on the other sheet faces the ambient. A highly insulating gas such as krypton fills the sealed space.
Claims10
An insulating window assembly, said window assembly comprising:
- (a) at least first and second sheets of glass spaced from one another at a width of 0.125 inch to 0.375 inch in face-to-face parallel relation, said first and second sheets of glass having opposed inwardly facing surfaces and outwardly facing surfaces;
- (b) fused marginal edges wherein said first and second glass sheets are attached to one another.,
- (c) at least one sealed air space, said air space disposed between said first and second glass sheets and filled with a gas;
- and
- (d) a coating with low emissivity and high visible light transmittance applied to at least one inwardly facing surface of one of said glass sheets and applied to the outwardly facing surface of the other of said glass sheets
