Refrigerated furniture represents the last link in the chain of food cold before the product is in the possession of the consumer, The development of products and especially food is essential, but this should not be at the expense of the consumer. quality of their conservation.

  • Good exposure includes good visual access to the products contained in the refrigerated cabinet without having to open it, however, during the exhibition, the refrigerated cabinet must maintain the temperature and ensure the conservation of products that need to be cooled or frozen. So, Due to the laws of thermodynamics and the opposite of the exposure function, furniture should at least protect products against thermal aggressions of all kinds, such as closing and opening doors.
  • Such thermal attack of a refrigerated enclosure is for example minimized by means of a glazed element as disclosed by DE 30 487 63 A .

  • Such a glazed element has the advantage of providing a larger transparent surface due to the absence of at least one lateral cross member on the movable support and the presence of a spacer and transparent peripheral seals while allowing a reduction of the energy consumption.
  • thermal insulation is usually determined by the overall performance of a glazed element in multiple glazing, defined by the thermal insulation coefficient. Several factors influence this coefficient. For example, the thermal bridges bonded to the glass as such, the fixing points of the glazing on the support structure, the joints distributed over the entire surface of the glazed element and finally the peripheral connection joints between each glazing commonly called spacers .
  • the thermal improvement remains generally insufficient and the use of such multiple glazing, because of their thickness and their weight, requires the use of a complete support frame, extending over the entire periphery of the glazing, which gives them good mechanical strength and better insulates the glazing. Nevertheless, the presence of a support frame creates a large footprint.
  • the invention proposes to substitute conventional insulating glazing elements included in a support frame, a glazed element comprising at least one insulating glazing consisting of at least two sheets of glass supported by a movable support devoid of lateral cross over at least one lateral edges, thus having a lower thickness while giving it good thermal insulation and a larger transparent surface.

  • These compounds are elastomers which, after crosslinking, have elastic properties. They have good resistance to oxidation and have a low permeability to water vapor. Silicones, which are elastomers with one or two components, are particularly preferred because of their adhesion to glass, their resistance to external agents and their aging. Butyls of "hot melt” type are hot melt rubbers with good resistance to penetration of moisture. Their firm consistency at normal temperatures makes them good candidates as sealants.
