Insulating glass is made of two or three panes, the space between which is determined by various lateral spacers. The spacer is filled with a desiccating agent with absorptive characteristics. Joining the glass to the spacers is done by a organic permanent plastic sealant, which creates a barrier against moisture penetrating between panes. The outer edge of the insulating glass is sealed with a flexible permanent two-component sealant with excellent mechanical properties. This doubly-sealed insulation glass guarentees high resistence to moisture entering any cavity and mechanical strain. Insulating glass is used in windows, doors, winter gardens and facades.
