Abstract
An insulated glass unit comprises two sheets of glass separated by an aluminum spacer, a thermosetting resin sealant such as a polysulphide or polyurethane sealant or a hot melt butyl sealant being applied around the edges of the unit to seal the sheets together. The spacer is connected by corner keys made of aluminum tape. Curing or melt-bonding of the sealant is accelerated by the application of microwave energy, suitably by passing the unit through a tunnel with microwave generators on each side thereof. The unit passes through the tunnel on a conveyor held upright by pinch chains. The conveyor and pinch chains are made of a nonpolar material such as polypropylene.
