Insulated Glass

Hardglass Industries Pvt Ltd offers Insulated Glass – 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 to maintain the mechanical strength of the joint but also protects the space between the glass from outside influences. The air enclosed between the two glass panes is dried with a desiccant. Because of the low heat conductivity of the enclosed dry air between the glass panes, heat transmission through the window is drastically reduced. The sealants delay the moisture getting into the air space and the desiccant absorbs the moisture coming through the seal. Process of insulating glass: this is done on world class Lisec plant. All materials like aluminum spacers, corner keys, desiccants and sealants are 100% imported and of international standards. The aluminium 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 washed and dried on the automated Lisec manufacturing line and conveyed to the assembly for last inspection and assembled with the aluminium 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 silicone. Suitable time for curing is allowed before final cleaning and transportation. The company also offers gas filled units in which case gas is filled using Lisec equipment before secondary sealant.
