Aluminum is made of GB6301t high-grade profile materials via double-spiral assembly processing. The reinforced nylon is employed to insulate the interior and exterior of the window frames to block the heat exchange for energy-saving purpose.

The aluminum is connected with the interior wood through special structure to let the materials of different thermal expansion coefficients have stable performance and not to be affected by the changes of cold and heat.

The exterior of the windows and the doors uses aluminum to achieve perfect matching of color and style. And the interior uses high quality wood.

 

Meanwhile 5+12A+5 double glazing and high quality German hardware are adopted to make the high-end windows and doors.
