Edge seal of the insulating glass.

The edge seal is a component of the insulating glazing and refers to the elements that join the panes with a special spacer (aluminium, stainless steel or plastic) and adhesives and sealants. On the one hand, the edge seal has the task of preventing the penetration of water vapour into the cavity and, on the other hand, of preventing the escape of the air or gas mixture from the cavity.
