Abstract

A glazed window frame, including a glazing panel set into a frame of channel shaped metal members with an elastomeric sealing material occupying each channel and engaging the two faces of the glass panel, the side flanges of the channel being formed or provided with means to limit or prevent escape of the sealing material from the channel.

Claims

1. A method of constructing a framed panel in which a plurality of frame members each providing an inwardly facing channel are assembled around a panel with the edges of the panel lying in the channels, and in which a viscous sealing material is introduced into each channel to provide a seal and to locate the edge of the panel, each channel being provided with a resilient sealing member along each of its side flanges to engage the adjacent face of the panel and limit escape of the sealing material therefrom.

2. A method according to claim 1, in which the sealing material is caused to flow into gaps between the faces of the panel and the side flanges of the channels, thus preventing contact betwen the panel and each channel.

3. A method according to claim 1, in which the sealing material is viscous when introduced, and is then caused or allowed to become more solid though elastomeric, when in position.

4. A method of constructing a framed panel in which a plurality of frame members each providing an inwardly facing channel are assembled around a panel with the edges of the panel lying in the channels, and in which a viscous sealing material is introduced into each channel to provide a seal and to locate the edge of the panel, the sealing material being injected into the channel of each frame member before the panel is introduced into the channel, and additional quantities of the sealing material being injected at the corners of the frame, and means are provided to prevent or limit the flow of excess sealing material from the channels.

5. A method of constructing a framed panel in which a plurality of frame members each providing an inwardly facing channel are assembled around a panel with the edges of the panel lying in the channels, and in which a viscous sealing material is introduced into each channel to provide a seal and to locate the edge of the panel, the sealing material being injected at a plurality of points around the frame after the panel has been located with its edge lying within the channels of the frame members, and means being provided to prevent or limit the flow of excess sealing material from the channels.

6. A framed panel, comprising a number of elongated frame members joined together at the corners of the frame, and each providing an inwardly directed channel around the frame, and a panel or glazing sheet located with its edges lying in the channel, with a sealing material located in the gap between the channel of the frame and the edges of the panel, and also engaging both faces of the panel, and in which each side flange of each channel is provided with a resilient sealing strip to engage the adjacent face of the panel and restrict escape of the sealing material.
