Introduction to Warm Edge Spacer Bar
A warm edge spacer bar is a crucial component in the production of insulating glass units (IGUs). Traditional spacer bars, typically made of aluminum, are good conductors of heat, which can lead to thermal bridging and energy loss in windows. Warm edge spacer bars, on the other hand, are designed to reduce heat transfer at the edge of the glass, improving the overall energy – efficiency of windows and doors. They help to prevent condensation on the inner surface of the glass, enhance the comfort of indoor environments, and lower energy consumption for heating and cooling. Warm Edge Spacer Bar
