Abstract

A multi-glazed window having at least two window panes which are spaced apart by a spacer frame consisting of straight rails and angular connecting members in the corners, each of said connecting members having an inclined surface limiting a triangular corner chamber in the frame which is filled with a sealing and/or glueing substance which is injected through a hole in the outer wall of the spacer frame, so that the said triangular corner chamber is completely filled with the said substance, and the cavities in the spacer frame is effectively closed, so that the space between the two window panes can be completely airtight.

Claims

1. A multi-glazed window having at least two window panes and a spacer frame between said panes, said frame comprising rigid, hollow space rails of substantially closed, rectangular cross-section having their corners mitre cut, and angular connecting members having legs inserted in the ends of the spacer rails for joining said corners of said rails edge against edge, said connecting members being completely solid or closed and at least a portion of their legs having a cross-section which fits tightly in the inner cross-section of said spacer rails, and each connecting member having an inclined surface defining with the spacer frame an outer closed corner chamber, there being a hole in the spacer frame connecting said chamber to the outer atmosphere for the injection of a sealing and/or glueing substance.

2. A window according to claim 1, wherein a second hole is provided in one of the walls of said corner chamber which faces one of said window panes.
