Desiccants also help to absorb moisture from the air, which prevents condensation and mould from the frame. The spacer bar is constructed of aluminium and is an essential component of the insulation system. The aluminum blocks the transfer of heat, but also keeps the edges of the insulated glass warm to avoid condensation.
