The cavity between the glass panes can be filled with either argon or desiccant. Argon, unlike air, has a lower thermal conductivity, which can reduce heat transfer. Furthermore, a desiccant adsorbs moisture from the air, to prevent condensation and mould from growing in the frame. The spacer bar that is usually made of aluminium, is a crucial part of the insulation system. The aluminium not only prevents heat transfer but also keeps the edge of the insulated window to avoid condensation.
