Energy Saving Aluminum Casement Window Inswing or Outswing

1. Aluminum is light but strong, the window frame and sash by aluminum alloy can expand the window view
2. Aluminum itself is heat conducted, the thermal barrier between the extruded aluminum alloy profile can help to prevent the heat conduction inside and outside
3. Standard 1in IGU( insulated glass unit) double  pane can help to improve the thermal performace, air infiltration, water resistance and sound insulation efficently
4. Durable window hardware make the window operate smoothly, and the whole window more sealed after closed. The energy efficieny is improved much as well.
