Definitions

• the invention relates to insulating glazing.
• a well-known type of insulating glazing comprises two sheets of glass which are spaced apart by a blade of gas such as air and which are separated and joined by means of a spacer frame constituted by hollow metal profiles folded or assembled by corner pieces.
• the profiles are lined with a molecular sieve which has the role, in particular, of absorbing the water molecules trapped in the interleaved air space during the manufacture of the glazing or which would penetrate thereafter and which would be liable to condense by cold weather, causing fogging.
• the spacer frame is glued to the glass sheets by an elastomeric cord of the butyl rubber type applied directly to the profiles by extrusion through a nozzle. Each corner of the spacer frame is also lined at the corner piece with butyl rubber.
• the elastomeric sealing bead acts as a temporary mechanical support for the glass sheets.
• a crosslinkable sealant of the polysulphide, polyurethane or silicone type is injected into the peripheral groove delimited by the two glass sheets and the spacer frame, which completes the mechanical assembly of the glass sheets.
• the main function of butyl rubber is to seal the interior of the glazing with water vapor and gases, while the sealant provides sealing against liquid water or solvents.
• a drawback posed by such manufacture is that of the storage of materials. In order to be operational for any new order placed for insulating glazing, many batches of each material must be disposal, which does not participate in simple and rapid management as regards the supply and storage of these materials.
• FR 2 807 783 and FR 01/13354 propose an insulating glazing whose choice of materials and the arrangement of the interlayer make it possible to facilitate the management of the manufacturing flow of glazing, to simplify assembly operations, and to restore glazing without destroy it, in particular by replacing the molecular sieve and / or reintroducing gas, which also makes it possible to reduce production costs.
• the interlayer consists of a substantially flat profile which is fixed to the glass sheets by its internal face while being pressed against the edges of the glass sheets.
• This profile may not be placed over the entire periphery of the glazing but on one part to at least play its role of interlayer, the other part of the periphery of the glazing being surrounded by another profile intended to present various functions.
• This other profile can for example be hollow to contain the molecular sieve, easy peeling and sticking of the substantially flat profile constituting the interlayer allowing easy access to the hollow profile to replace the sieve.
• This other profile may also have a shape suitable for wedging and / or fixing the glazing in the bay for which it is intended.
• the configuration and the material of the interlayer therefore allow it to be placed on the edges of the glass sheets, which moreover makes it possible to increase visibility through the glazing.
