Reliable double hung Window Manufacturers from china
In double hung windows, the sashes move in rails in the plane of the window. They do not rotate or swing in the room, so curtains and sill decorations do not get in the way when you open the window.
Grandsea Windows and Doors will design and manufacture the perfect double-hung window for your application, ensuring that the sashes that separate the opening do not obstruct the view of anyone sitting or standing in the room. For larger window areas, only part of the area is usually designed as a vertical sliding window.
Glass cleaning in double-hung windows is more complicated than with, for example, tilt-and-turn sash windows: the glass must be removed from the vertical rails to be cleaned.
Excellent ventilation effect
Our double hung windows allow both upper and lower sashes to be opened at the same time, creating excellent natural ventilation effect and effectively improving indoor air quality.
Flexible opening control
The opening degree of the upper and lower sashes can be freely adjusted to accurately control the ventilation volume to meet the needs of different seasons and weather.
Enhanced security
Equipped with a multi-point locking system and tempered glass, it greatly improves home security and gives you peace of mind.
Convenient cleaning and maintenance
The innovative tilting design allows the sash to tilt inward, allowing you to easily clean the outer glass without the help of ladders or professional tools.
Excellent energy-saving performance
Adopting advanced Low-E glass and sealing technology, it effectively blocks heat transfer, helping you reduce energy consumption and save money.
Classic and beautiful design
The perfect fusion of traditional and modern design is suitable for various architectural styles and adds timeless charm to your home.

Get Every Answers About double hung windows
Double hung windows consist of two vertical sliding sashes within a single frame, which can slide vertically; casements can only swing outward or inward. Casement windows can be opened fully, while double hung windows can only be opened halfway. Casement windows are usually better sealed.
The cost to replace a double-hung window can vary widely, including labor costs and the cost of purchasing the window. Professional installation typically costs around $150 per window, and window costs depend primarily on window size, frame material, and features. In Grandsea, a standard aluminum double-hung window costs $300.
