Aluminium Double Hung Sash Windows

Aluminium double hung sash windows use two sashes that slide vertically. This is a classic window type commonly seen in North American residential styles. The upper and lower sashes can be opened separately, allowing users to adjust ventilation from the top or bottom.

When opened, the sash does not swing inward or outward. This makes the window suitable for areas near furniture, curtains, exterior passages, or compact spaces.

Profile depth options commonly include 70mm, 90mm, and 120mm series. The sash lifting system can be configured with a spring balancer or constant force balance system. These options help the sash slide smoothly and remain stable during daily operation.

Glass options include single glass, insulated glass, Low-E glass, or laminated glass. The product can also be equipped with screens, grille bars, and tilt-in cleaning structures. These options support ventilation, insect protection, decorative needs, and easier routine maintenance.

This aluminium double hung sash windowst is suitable for North American residences, apartments, townhouses, old house renovation, school dormitories, senior apartments, and light commercial buildings. Its appearance is simple and works well for unified facade design.

Compared with a single opening structure, the upper and lower sash design gives users more flexible ventilation control. For standardized housing projects and renovation work, this window can balance space saving, ventilation adjustment, and installation adaptability.

When purchasing this product, buyers can focus on profile series, sash size, balance system type, glass configuration, and whether screens or grille bars are required. The product can support mixed colors or models within the same minimum order quantity. Samples can also be provided for confirmation.
