Double-Hung windows are one of the most popular styles for homeowners. The window can be operated from the bottom or top sash, sliding up and down for ventilation. Since it opens and closes without protruding, double-hung windows are an excellent choice for rooms facing walkways, porches or patios.

The Advantages for Aluminium Windows and Doors

1. Sound insulation—(windows and doors are dedicatedly 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. Windproof–(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. Waterproof—( the frames of windows and doors adopt a three-cavity design and feature strong rigidity, the independent drain cavity can ensure 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 resist aging for over 10 years, the airtightness 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.)

6. Surface— (it is treated with corrosion and aging resistance, which ensures fresh and beautiful surface in any place and environment.)
