Cool Edge

SWISSPACER's warm edge spacer bars have low thermal conductivity so in winter they reduce the amount of heat escaping from buildings to maintain a comfortable indoor temperature and reduce energy bills. They work in the same way to achieve the opposite effect in warm climates where air conditioning is used to keep buildings cool. ‘Cool edge’ reduces heat transfer from the outside to the inside thus minimising the warm edge on the inside of the window. Air conditioning has less work to do which cuts the cost of air conditioning bills.
