The insulted glass is a prefabricated unit made of two or more glass panes, which have been separated by an air gap and edge-sealed together. This edge seal not only binds the individual sheets of glass together. This edge seal not only binds the individual sheets of glass together. To maintain the mechanical strength of the joint but also projects the space between the glass from outside influence. The air enclosed between the two glass panes, heat transmission through the window is drastically reduced.
The moisture getting into the space and the desiccant absorbs the moisture coming through the seal.
All material like aluminum spacers, corner keys, desiccants and sealants are 100% imported and of international standards. The aluminum spacers are cut to size, filled with desiccant and joined at the edges in the form of a frame, primary sealant butyl (polyisobutalyne) is applied to the edges and made ready to be incorporated in the assembly. Glasses are and dried on the computerized manufacturing line and conveyed to the assembly for last inspection and assembled with aluminum spacer in which primary sealant has already been applied. The assembly is then pressed and conveyed to the applicator table for applying the secondary sealant which is two part polysulphide or two part structural silicon. Suitable time for curing is allowed before final cleaning and transportation.
The aluminum profile or space bar is responsible for establishing the precise distance between the glass panes, as there is a correlation between the glass panes and the energy saving properties, and last but not the least the absorbent will dry the cavity filling completely to prevents the condensation inside the glass panes. The moisture which has to be absorbed comes from the wet air which is trapped into the intermediate airspace during the production and form the moisture vapour which penetrates through the sealant during the lifetime of the insulating glass unit.
