A glass insulating sealed unit suitable for capless or stopless glazing comprising two spaced-apart glass plates and spacers to separate and join the glass plates arranged about the entire periphery of the plates and between the plates. The spacers are adapted for connection of the unit to adjoining support members in order to support and fix the unit. The preferred spaces each comprise a generally channel-shaped member having its elongate recess open along the edge of the unit. Structural sealant on two opposite sides of each spacer bond each of said sides to the adjacent inside surface of a respective glass plate. An elongate strip of compound providing both dessicant and vapor seal extends between the glass plates and along inside surface of the spacer. Each spacer is preferably connected to a support member by means of flat clips evenly spaced along the spacer and threaded connectors extending through holes in said clips. Each clip has two flat ends with the thickness of each end being about equal to or less than the width of the recess formed by the spacer. The dual purpose compound can be a combination of butyl rubber and polyisolbutylene that adheres to the glass plates and is capable of continuing to adhere to either glass plate in the event the structural sealant fails.
A glass insulating sealed unit capable of being mounted on a building without the use of exterior stops comprising at least two spaced-apart glass plates and spacer means to join and seal the edge portions of said glass plates arranged about the entire periphery of said plates and between said plates, said spacer means including at least one connecting spacer device extending along at least one side of said unit having a channel-shaped recess that is open along the edge of the unit, structural sealant on two opposite sides of said spacer device bonding each of said sides to an adjacent inside surface of a respective glass plate, and an elongate strip of compound capable of providing both a dessicant and a vapour seal extending between the glass plates and immediately adjacent to the surface of said spacer device which faces towards the centre of the sealed unit and wherein said spacer device is adapted for the connection of said unit to an adjoining support member so that the exterior glass surface thereof is the outermost point of the unit and adjacent surrounding surfaces of said building.
A glass insulating sealed unit capable of being mounted on a building without the use of exterior stops comprising at least two spaced-apart glass plates and spacer means to join and seal the edge portions of said glass plates arranged about the entire periphery of said plates and between said plates, said spacer means being inset from the edges of said unit, separate connecting means for fastening said sealed unit to an adjoining support member, said connecting means having an end portion having a thickness less than or equal to the distance between the glass plates, wherein said sealed unit is fastened to said support member by insertion of said end portion into the edge recess formed by the inset of the spacer means and by attachment of said connecting means to said adjoining support member and said sealed unit is adapted to be held in place and supported on said adjoining support member by being clamped to said support member by said connecting means and wherein after the clamping operation the exterior glass surface is the outermost point of the unit and adjacent surrounding surfaces of said building.
A glass insulating sealed unit capable of being mounted on a building without the use of exterior stops comprising two spaced-apart glass plates and spacer means to join and seal the edge portions of said glass plates arranged about the entire periphery of said plates and between said plates, said spacer means including spacer members extending along each side of said unit and having a channel-shaped recess that is open along the edge of the unit, and a separate unitized connecting frame for fastening said sealed unit by means of the spacer members to adjoining supports, said frame having a hook portion extending about its perimeter on one side of said frame, wherein said hook portion has a flat end section that projects into said recess on all sides of said sealed unit and after said frame has been fastened to said adjoining supports the exterior glass surface is the outermost point of the unit and adjacent surrounding surfaces of said building.
