Reduced Conductivity with Warm-Edge Spacer
Most of the heat loss in patio doors can be attributed to conduction through solid materials (eg. thermo spacers, glass, door sashes and frames). Heat conducts from the warmer to the cooler side of the door. All our insulated glass units are made with warm-edge spacers that reduces conductivity by 75% when compared to conventional aluminum spacers, offering superior insulation performance.
