O-ring gasket configuration
Ensuring a reliable seal against air and dust infiltration is essential if a museum display cabinet is to do its job of conserving fragile objects appropriately.
The standard solution
Some cases on the market use gaskets and/or sealants along both the edges and flat surfaces of the glass panes to achieve an airtight chamber. This approach often creates a mismatch between surfaces with gaskets and those with sealant.
Goppion’s innovative approach always places the gaskets on the edges of the panes of glass and therefore on the same plane. We incorporate the case’s horizontal components (display deck and light attic) within the area enclosed by the gasket system, employing a topographical O-ring configuration, while making the technical compartments (housing the lighting apparatus in the upper section and containing hygroscopic material in the lower) independently accessible. As a result, we can create irregular rectangular units that can be made airtight by the application of an O-ring seal on their outer perimeter.
