SWISSPACER is at the heart of energy saving windows. Warm edge spacer bars insulate the edges of an energy efficient sealed unit. They keep the panes of glass apart and maintain the integrity of the air gap that insulates a building from heat loss through windows.
This loss is not only reflected in a building's energy balance, but also leads to a cooling of the inside surface temperature along the glass edge - i.e. the edge becomes cold. If the surface temperature sinks below the dew point temperature of the surrounding air, condensation will develop - a comfort and hygiene flaw which consumers frequently object to. Apart from the health risks posed to residents, long-term condensation can also cause damage to the window frame.
