The technology of casement windows:
In manufacturing, sliding windows are generally simple in structure and have no special requirements for equipment, so they are manufactured in small workshops with small electric saws. Casement windows need a better "angle bumper" and "double-head cutting saw king" to produce excellent aluminium alloy flat windows because they are connected by 45 degrees thick aluminium alloy corner pieces.
In summary, casement windows are superior to sliding windows in performance, and they are widely used.

Features of windows
1. Sound insulation
windows and door are designed and selected, their sealing property is several times higher than that of original windows and doors. They can insulate above 30DB noise outside the windows.
2. Wind proof
strong firmness is ensured by super thick profile and refined three dimensional structural shape design and fixing them with screw on the frames of windows and doors.
3. Water proof
the frames of windows and doors adopt three-cavity design and feature strong rigidity, the independent drain cavity can ensure the smooth drainage in any case.
4. Heat insulation
quality heat-insulated materials are used and feature strong anti-flaming and fireproof performance.
5. Watertight and Airtight
imported adhesive tape is used and can be resist aging for over 10 years, the air tightness is less than0.5M/M.H, and the water tightness is more than 350PA, therefore, it can prevent gale and rainstorm from against the air windows.
