Additionally Plasto offers special TGI/SWS spacers in insulated glass units. These spacers are made of plastic and compared with aluminium spacers they are more efficient in preventing thermal bridging. As the TGI/SWS-spacer has low thermal conductivity, cold does not reach the inner pane. In this way the TGI/SWS-spacer helps reduce heat loss and avoid the occurrence of condensate on the windows. The efficiency of the TGI/SWS-spacer compared with the aluminium spacer is about 50 – 60%. Hence, a Plasto window together with the TGI/SWS-spacer is even more heat efficient and resistant to condensation.
